H22A4 Continued after the bell

Read back – few typo’s

Dont care…   because what we are doing here…  is BELTING OUT DOCUMENTATION

A MAP…  to what we need to capture.

Typo, technical errors, omissions – unimportant for the expert..  as the expert will (on the second pass) easily catch and correct these things.

SPARK

A nominal 12V battery operates with a single coil.  There is a Fixed distributor (does not rotate and fires off of a TDC sensor).  It has, as you would expect, a rotor, points, wires, plugs.

Plugs are firing -not a wet plug to be found.

Plug wires were “sloppy loose” so…  went ahead and replaced the Rotor (broke the internal insulator hood – as I do every time…  Did not replace the gasket.  Did have to soak out the distributor with PB Blaster and “Chip it away” to get it off (rust).

The replacement parts were PURE GARBAGE procured from AutoZone.  Rotor was sloppy loose, cap was from a loose mold, wires were not adjusted correctly and did not sit “locked”…  sigh…  whatever…  it snaps and starts.

I replaced the ($14 each) Platinum plugs with ($2.50) Each copper plugs.  Fine by me, thats a service item.

Coil…  yea…  could be an issue.  Might be overheating…  dont think so.

Spark timing…  could be an issue.  Would manifest in different ways at different RPM at different loads.  Its feels fine to me.

 

FUEL

This is where I am focused…  for several reasons

I do not believe a stoichiometric ratio is being maintained in the high power range*

Fuel tank is between the trunk and the rear passenger seat.  Fuel pump is accessed under a flap and is mounted in the tank.  It has a “Sock” which…  for the reader…  I have run down to empty AT LEAST 200 times.

I have run different pumps at different times.  Larger pumps require modification to the fuel pressure regulator (later)

Anyhow – this pump has the job of pressing as hard as it can on the fuel system.  It maintains a good head on the fuel lines.  Those lines go thru a secondary filter – which is hard to replace – which I replaced.  The old filter had no gunk in it (nobody poured sugar into my take as far as I can tell)

From there we go into a regulator who’s job it is … to maintain a STEADY KNOWN PRESSURE on the fuel rail.  This is crude and related to vacuum.  At high vacuum levels a valve pulls back and allows fuel to return to the tank.  At low vacuum levels the return path is restricted and higher pressure is achieved.

This is hard-mapped into the fuel tables and trimmed thru long and short adjustments based on primary O2 feedback

So…  I swapped the fuel pressure regulator with an un-known good unit.  No change

The rail then goes into a set of injectors which can gum up.  Tons of ways for an engine to run fine at low flow rates and fall off at high flow rates

But remember…  I was stomping on it…  running 120MPH…  wide open at 8,000RPM…  when POP – something went.

Suck a bag up into the intake?  Suck a valve into the combustion chamber?  Hmmm…  who knows

So….

I dont really suspect the injectors and if I did…  I would flush the system with a solvant (that would not eat the o-rings) and be done with it.

At this point…  measurements are required.

There is something called a banjo bolt – on the fuel rail and on the fuel filter.  It attaches the fuel line by allowing gas to flow thru a small hole (its a hollow bolt).  These sometimes come with a second threaded hole atop that…  for screwing in a Fuel Pressure Regulator (or bleeding – WHICH DOES NOT NEED TO HAPPEN)

I have 2 or 3 fuel pressure regulators.  I have extension hoses to run them out of the engine bay and up to the driver window (NEVER) inside.  I could run a sensor with a sender…    any number of solutions.

What I need to know at this point is:

1)  What is the fuel pressure with a closed throttle body

2)  What is the fuel pressure with vacuum line removed (affirms it is working)

3)  What is the fuel pressure (on the RAIL) under wide open throttle at High RPM???

IF – the fuel pump can not keep up with this need….  THEN…  I need to dig into that shit pot and swap it out.

Fuel pressure is…  collected…  in the….  system.

Stored energy – like a capacitor.

In the lines, in the fuel filter, on the rail….  ready for dynamic response.

It is possible to have a fuel pump capable of high pressure but incapable of high flow that could easily run a car at lower loads then falter near instantly at high loads.

This would point at the fuel sock…  not at the pump…  because if the pump were getting weak…  eh…  let me think about that…

….

Well…  the pump is working against back pressure.  The highest backpressure is at idle (er… no…  this is when bypass is enabled)…  well then…

We need to measure flow

We must measure flow in order to correlate the work that the pump needs to do at the time when the backpressure from the fuel regulator is offset by the flow thru the injectors.

Yea – anyway…

Voltage to that pump is maximized at higher RPM (unless for some reason the ignition system is eating up too much current and the voltage sags…)

Which it has MANY times… since I regularly run the motor on only the alternator with no battery.

The battery acts as a (snip) – dont know, dont care.

The pump has seen a lot of work.  It was procured by a huckster…  as my original pump…  the wallbro…  was HUGE…  and required a modified (Drilled) fuel regulator to keep fuel pressures SANE.

Wait a second…  dude…  did Matthew forget to swap out the racing fuel pump and accidentally match it to the factory fuel pressure regulator ?!?!?

Hmmm.. …..   This could definitely cause some premature wear.

Well…  anyway…

Since I “did my thing” (patented Schindler Magic Show) at work – I have a few days off to “Think about where I want to work”

Says my Direct Manager and his Director (and Presumably his VP).

See…  I really dont give a fuck about political correctness or playing the game by the rules.  This is what makes me special and different.  I am like dig-dug gone berserk when rooting around for trouble.  I allow NO PERSON to skew my perception of how and why a system works well or does not work well.

I do not drink my Koolaid.  I do not eat my Flintstones vitamins.  I do not take an “Anti-Depressant”…  or any other substance that gives me a false sense of wellness…  when things may or may not be well.

SCHINDLER – ON HEIGHTENED ALERT – AT ALL FUCKING TIMES

(Its a Vet thing… you will never understand if you dont already) – hopefully

Now…  I do allow people to skew my view…..

(continued from above)

(Except those people who steer and point me to the problems…  those people who I have infinite love for…  even a whisper in the hallway…  a loud conversation across the room…  a mention during a walk…  a slip during lunch)

I pick up the sent of trouble from small talk…  and that is where investigation and troubleshooting begins…

Because let me tell you ….

At EVERY company I have EVER worked at there are ALWAYS some number of GLARING problems that are SO obvious that NOBODY addresses them and they become MALIGNANT.

So I pound on the war drum when I find these problems.

Shakes people up.  Oh well, dont know, dont care…  Back to what I was doing.  My cathartic writing…

ah….  Where was I?

(FYI – currently I am working at a spot that pretty well has a handle on rapidly responding to issues found in a healthy way.  FOR THE MOST PART.  There is some room for improvement in the ladder.  )

Ya know what…  more on that…

***

It is required that a chain of command works on something more than trust…  so as one goes up the chain…  it is expected that the breadth and depth (relative to the subject matter at hand) becomes more rich…  such that this person can SHOOT FROM THE HIP and just know they are right.

If we go up the chain and reach individuals who have to take guidance from above or below we end up with a bottle neck.

This happens when ORGS or divisions (that should be separate) are mashed together due to budget, resources, schedule, decisions – what ever.

I always report up the chain.

First my Team – keep it local

Then my Manager – escalate

Then his Uppers – in an order which will tell me who is who and what is what

I have no fear of the CEO, CTO, VP’s, Senior Managers, Directors, Managers…  because…

Usually…

None of them have SIGNIFICANTLY more experience or SIGNIFICANTLY more pedigree or SIGNIFICANTLY more brain-juice than I do.

They simply steer toward the organizational side of things while I steer toward the technical side of things.

So…  WE ARE ON EQUAL FOOTING

Because I make technical decisions…  which…  are just as heavy as programmatic decisions.

Anyway kids…  never let the flock scare you.  If you are a bad-ass engineer…  own your opinion.  Adjust it quickly.  Speak up and speak loud and clear.

Be ready at ALL TIMES to get kicked in the teeth, stabbed in the back, fired, undermined, bit by sheep, and all of the things that come with climbing up the ladder.

Jesus how do I get off on these rants?

Oh yea…  because I am bringing up a new generation of engineers.

Real fucking engineers.

Not PC engineers, or mandatory minimum engineers, or male engineers…  ANY GOD DAMN WARM BODY THAT CAN HOLD ITS OWN

You hear me?

Give a fuck if you are gay, black, female, foreign, crazy, deformed, or even high on some kind of pharmaceutical.  Even all those things….

The one and only one thing I judge an Engineer by is their ability to  Engineer.

Engineering happens in different ways at different times…  as and where required.

Under fire, while at rest

Accurate to the best of your ability

Precise to the best of your ability

Complete to the best of your abiity

You do that for me…  and I will find a way to work around your geeks and tweaks.

Ok…  Ok…  back on track….

Fuel systems in an H22A4

 

NOP

 

Lets go on a 30 page rant about the state of Engineering …  what we have, what is needed, what happened last time…

Dude…  is anyone aware of the fact that we just pulled out of the hardest curve anyone has ever witnessed since the dawn of human?

1970

1980

1990

2000

2010

2020

Dude….  Seriously dude….

I have been asked (and have answered) to understand ALL OF THAT

AND

ALL that came before it…  the foundation

D O    Y O U   H A V E  A N Y  I D E A

Of how much my mind has had to grow to encapsulate that body of knowledge?

From the Gates thru the chips thru the joints thru the boards thru the firmware thru the software thru the system….  the sensors and API’s…  the communication protocols…

OMFG the communication protocols…

The conceptual level…  hardware level…  built in functionality level…  the paradigms and methods and ways…

The noise and losses and reflections and buffers and decoding

THE DECODING…..

The Cyclic Redundancy…  the Hybrid FIFO Queues….  The 5200 MESSAGES a second we have to process…

The ingress and shock and vibration and temperature

The 42 fucking programming languges

The 42 fucking cultures that pour into engineering

The constant bombardment of new and better parts…  with new and more fleeting loose ends…

The data sheets…  hundreds and hundreds of pages describing buffers and registers and and timing and ….

See….

While Mechanical engineers stepped into Modeling tools that effectively do their job for them…

3D printers that just fart out whatever they can imagine instantly at no cost

3D modeling that gives you very close to 100% feedback…

We over here in (what was called…) Electrical Engineering have had to take the helm.

We are forced to master

SOFTWARE ENGINEERING

FIRMWARE ENGINEERING

PCB ENGINEERING

NETWORK ENGINEERING

ELECTRONICS ENGINEERING

ELECTRICAL ENGINEERING

MECHANICAL ENGINEERING

VALUE ENGINEERING

I can go on like that…

and I am not talking about “Familiar with” here…

I am talking about WORKING KNOWLEDGE used on a DAILY BASIS to make SYSTEM LEVEL decisions which aim at SHIT THAT WORKS

Sigh…

Software Engineers have had an easy run as well….  their compilers (tools I have MADE for them) have become better and better…  languages easier and easier.

Dude…  Do not tell me…

I had to roll with the ORIGINAL SHIT

The Assembly language

The versions of C that still had BUGS

Like..  the VERY LANGUAGE AND ITS COMPILER had BUGS.

Lol…

And I ride a skateboard to work.

 

Must be because I am a prick.

 

fuck it.

 

I learned all of those professions (Dumped thousands and thousands of MY hours into learning those things) for Myself.

If people cant see it…  or do not appreciate it…  or are unable to open their minds to the fact that some of us are poly….

Sheeeit

Its a capitalist paradigm.

 

Go ahead.

Take my house.  Take my job.  Take my car.

Take my reputation.

I could give a fuck….

 

Because when the avalanche comes….

When the water gushes….

I know what I am doing

 

Proven

And proven and proven and proven…  even when faced with impossibly contorted proofs …  even when I fall flat on my face…  even when I have to crawl the ceiling.

Like a god damn poltergeist over here.

RELIABILITY, then SAFETY, then QUALITY, then VALUE

Thats the order I do things.

I can explain it….

 

Now where was I?  Oh yea…  H22A4….  fucking gas engine.

Why am I not making enough money to buy 3 wrecked Tesla and tear them apart into a new Vehicle?

Clearly because….  eh…

-Patrick

 

P.S.  Thats called an “Epic Rant”

These days I have to store them up and let them loose “late” since…  the world is so connected.  I have some more really good rants about my experiences at Zero Motorcycles.

My favorite is where (I HEARD) that the Sales Guys (and the like) were pulling like $250k while I was getting paid $40k (or more…) under market as the Quality Engineer.

What does that tell you?

Yea…
Respect and Pay your Quality Team.  They are very important.

 

 

The H22A4

Ack…  So tired that my eyes are still crossed.  Its 4:27 – Plenty of time.

 

Symptom:

Engine was producing close to 200hp, revving up past 7,500RPM, producing steady torque with no dead bands or hiccups.

Something blew out (or sucked in?)

At this exact moment in time the engine performs flawlessly in economy mode.  As soon as the secondary lobes (and secondary runners, fuel map, ignition timing etc) switch –  the engine has a range of trouble.

It can be as bad as “wont run” to as good as “its is almost working”

There is very heavy blow-by coming out of the oil cap (more than previous motors, I think this is the 4th H22 the chassis has seen).

The plugs are reading (by my account…) lean.  Now…  I read plugs for forced induction and I am looking for maximum power…  so tan, maybe like coffee with cream.  These plugs are pretty white (Far from the whitest I have seen) and there are signs of preignition/detonation (specs).

Now remember…  It starts perfect, idles as expected, free turns as expected, drives under load, below 30% throttle, up to 7,000 RPM – just as perfect as you could ask for.

The engine will also produce torque and low RPM if I step into it.

Its High RPM, High Load (after the switch-over point) where it either stutters or bogs or just does not work well.

An engine needs an Air to Fuel ratio along with a spark to operate (I will not get into compression, dynamic compression, spark timing, or any second order stuff)

An appropriate (translated functional) A/F Ratio is anywhere from…  eh… 8:1   ….  all the way up to 15:1, maybe 16:1  (those are numbers from my tuning with my WB02 with my engine in my operating environment).  8:1 is considered “PIG RICH” and results in poor performance.  Climbing into 9:1 gets you close to the optimal window where “you cant tell”.  After 10:1, 11:1, 12:1…..  most of those, with forced induction, “will work” for the most part…  if you must.

12.5:1    Good place to aim for for Supercharged High Compression (says the guy who is on his 4th motor lol…)

Climbing up into the 13’s, 14’s 15’s….  distinct power loss can be butt-felt above 15:1.  Up into the 16’s (outside of my accurate measurement range) you can flutter the power.

Anyway – these plugs are reading 14.7:1  (i.e. Normal…  not my tune)

 

Troubleshooting:

We all have our methods and ways.  Sometimes it is to get the car running NOW, sometimes to get the car to a certain LEVEL, sometimes just to tinker and learn.

First is learning what you are working with.

 

 

AIR:   What affects it

Factory with a Cold Air intake.  Remote actuated flapper upstream of the filter (to reduce noise with a resonant chamber) – likely…  not wired up…  need to check it.

Air Filter – duh they clog up

Throttle Body & Plenum – Big vacuum leaks here can allow unmetered airflow (NOT TRUE FOR HONDA) into the combustion chamber without fuel to match it.  Yes…  the Primary O2 SHOULD detect this and go rich on the table by a few percent…  but that is not the correct way to go about it…  as (its a 2D table) at any given time we are in a cell (Spreadsheet) which correlates to Manifold Absolute Pressure and RPM.  HALT.  We are measuring the vacuum on the plenum so a vacuum leak WILL register – unlike with a MAF vehicle.  The only thing that will be affected is the IAB (Intake Air Bypass) PWM and a little of the TPS (Throttle Position Tuning).

Secondary Runners – 4 intake runners are open all the time.  A matching 4 are on a set of butterflies which are spring loaded.  They rest OPEN (Free flow).  A vacuum chamber with a check valve and a pneumatic switch control them.  At apx 4200 or 4500 RPM they open up.

Valves – 4 per cylinder, 2 on the job of intake, 2 on the job of exhaust

  • In the airflow path we must respect the exhaust!

So….  there is a CAT that can get packed full of oil and debris.  Several resonators (pretty clear shot) and a muffler (also a clear enough shot) – with the highest probability of back-pressure developing at the CAT….  due to running an engine which burns oil and runs rich at lower temperatures for extended periods of time (Packing).

So…  Yesterday I went ahead and swapped the air filter.  There is something VERY LOUD in the exhaust or attached to the exhaust.  Will see what later.  Probably a valve or a head bolt.

O-Rings vs Potting

For anything mobile I would pot it.  Space ship…  Cruise Missile…  Automotive Engine Component.

For anything stationary I would O-Ring seal into an enclosure.  (These days you can probably even get a seal out of 3D printed parts.)

Which connectors and how they exit the PCB is the interesting part.  This is where C.O.T.S. becomes REAL important.  Avoid custom at every turn.

4:20 Posts…

If nobody has caught on yet…

I have been doing a series of posts that go public at 4:20AM PDT daily.

Here and there…  in this venue and that venue… from whatever device is in front of me…  from whatever screen name I happen to be logged in as.

(And I utilize a persistent online Identity, unmasked IP, and distinct signature of prose…  so this is not “Troll Work” or “Anonymous” or “Terrorism”)

((lol not funny))

 

This is Captain’s Log – USA

 

This is not a copy and paste activity.  Its a “Wake up sick to my stomach at 3:20AM” … activity…

So its stored ammo…  but stored only in my mind…  and spilled out as fast as possible…  with no editing…  so as to “keep it real” (note – if you address my truth by judging my spelling and grammar you ARE retarded – … by definition).

Yea…  so…

Thats all I feel like writing today.

I am not a reporter – BUT I AM

I am not an MP – BUT I AM

I am brutally honest – AND THAT IS WHAT IS NEEDED – AND THAT IS MY DUTY.

So…..

If I audit you (and I can, in various ways)…  or you audit me (which you can, in various ways)…  remember at all times that I am Schindler.

Worth more that way.

Rules of Engagement

When a man is on private property (especially his own private property… no matter what anybody says or has said…) we do not shoot him.

Even if he is black. . .

Note:  Those are my people, I have been right there, with my wife and child on the street….   facing off with costumed humans wearing armor and wielding weapons….  stopping injustice from happening again.

(The particular injustice I speak of was around housing prices…  but that is a story for another day…  and I am a man who has built more than 1 house)

Anyway –

The article skipped the details (that led police to him…) and that’s fine.  It is an Order of Magnitude thing.  I do not care why the police were there.  A man is dead.

This is an example of SYSTEMATIC INJUSTICE, which I have experience with.

 

Life Proof:

A woman once systematically called wolf (the police) on me as well.  Am I dead?

Swat team came out onto our property with Assault Rifles.  At night.  Way out in the woods.  Up my very steep and scary driveway.  No lights…

NOT WELCOME just oozes from the approach to my home at night. . .  Cops must have been… (and rightly should have been)…  scared for their life on the approach.

 

WAIT

 

!!  Just because they are “Scared for their life” they can shoot ME!! ?

!! On my property !! ?

!! On the word of a liar !! ?

 

WHAT THE FUCK?

 

I did not get shot for 3 or so reasons.

  1. It was the Santa Cruz County Sheriffs…  and they are, for the most part, seasoned and smart.
  2. ********************************************************* Redacted *********************
  3. My “boom-stick”, (the one I train with and use to scare off Mountain Lion and Criminals, Glock 22 SE, S/N MAB022), was in its lock box, marked as appropriate, in plane view – … thru the french doors that I salvaged from Craigs List and installed…. into the wall of the house I salvaged, that we were living in.
  4. I came out in my fucking tight black underwear and did a dance for the boys with the machine guns.
  5. They followed PROCEDURE and secured the situation by pulling pops out of the house, surrounding him, and CLEARING THE SCENE.
  6. The men with machine guns then left my property…  but not before yelling “GOOD…. LUCK…. BUDDY….”

Ya see…

(and there are a lot of topics to cover here…)

In life there are 3 things

RIGHT NOW

VERY SOON

THE FUTURE

You better be integrating RIGHT NOW so as to INSTANTLY manifest your VERY SOON in a way that lands you in THE FUTURE you want.

Otherwise you may likely land in the FUTURE someone else wants (another story)

Since I am a decorated citizen (MSEE)…  retired servant (NNSA)…  and extremely active member of the work force and social movement scene…

It should be OBVIOUS to any LAW…  that my ability to integrate the future in the immediate…  (by adjusting my position, velocity, and acceleration…) is above reproach.

Should I be shot by any law…  or should the law attempt to unnecessarily corner me…  its highly probable that an injustice has occurred.

Oh now on that account…   have I got something to  ->  FUCKING SAY.

  1.  It aint about the Military Industrial Complex
  2. It aint about Politics or Economics
  3. It aint about our Orange Future (first it was green, then blue, then red…  now Orange…  its an emerging market thing… just go with it… and really soon we will have mobile batteries everywhere capable of freeing you from the existing grid infrastructure…)

 

Its a story about Liars.

 

 

How you catch a liar.

How you spot a liar.

Why a liar lies

How they do it, why they do it, what they are thinking….

 

I have 3 on the hook right now.  Set DEEP…  way past the barb.

 

I usually play “Catch and Release”…  or…   “Catch and Hand Off”…  but this time…  I am going to take the needle nose pliers…  reach into these liars mouths…  and pull those hooks out.

 

Just like I do when I catch a fish.

Updates: I like them in bunches

  • The “Resources for Solving Problems” page has seen an update.
  • As for Schindler Engineering Services…  Looks like they are up for grabs:  -> as I am dead-short on cash  <-   (after being annihilated in court by my previous partner).

Looking to get paid @ Industry rates or better.

Facebook

See?

It is that easy.

Just speak your truth…  then kill your Facebook page.

(after backing it up and cloning it of course DUH)

 

 

Be like Elon Musk.  Change the world in a positive way.  Your way.

Its easy with a little practice.

Stand up and fight for a brighter future.

 

 

There is no “US and THEM”.  Only US.

 

 

Go for the WIN,WIN every time…  and accept no false dilemma of the:

WIN,LOSE

LOSE,WIN

LOSE, LOSE

 

Those are games that our predecessors played.  We do not play those games.  We play only for the WIN,WIN… and in my game…  everybody can WIN.

Fully Distributed (and qualified…) BMS

The proper way to do it…

The hardware landed last week (very nice kit complete to the wire ends).  Today we had the kick-off that green-lighted us for testing.

What we are looking at is a secure ISOspi bus behind a CAN firewall.  We will be developing some TEST ONLY hardware to interface with and exercise this system.  Look for pics as things develop.

Week 1)  Get the firmware playing nice, confirm command line communication and power draw, put together the LabView spread for viewing all data and exercising all functions.

We will be spending equal time between expanding functional test and trying to break basic functionality (every permutation of what could possibly hang the hardware in a high power state…  so basically…  just testing the dead man and handshake timers).

I have pics now…  but on the run late for my day job (as a superhero)

FYI:  Schindler Engineering is back on non-profit work for now.  That was always where we gave our best performance anyway…  More fun that way.  Sporting.

thanks, – Patrick
