First week of school out of the way, already 3 projects completed.. I like tradeschools :) I worked a lil on the 'engine' over the weekend, finally got a look into the code base, specifically the RPM calculator and the events. I need to adopt a similar rpm/crank angle setup (I should just get a fran...

No injectors clicking just yet.. working towards the pressure regulation

School starts on Monday..

Silhouette, or Silly for short.

.. just recently 18mo, and finally got "fixed" on Monday

At least you didnt call him 'Pongo'

that was the shipping pallet.. getting it off of it will require a lift + engine stand.. which are on the list

Cleaned up the second (downstairs) kitchen - somewhat, which is also now the only entrance since I removed the upper entrance front door (still no permits, I may need an engineer's stamp for seismic retrofit). I moved my chemistry stuff (some of it) to where I was housing some of the construction st...

Yup.. and cleaned up the kitchen today.. had replaced the window (that got drenched in bio) a few days ago.. flow bench kinda got a bit of sawdust + gypsum on it, but the real mess came from plant pots that fell over and spilled soil everywhere.. I may have a few days downtime of doing house work, s...

ok.. I'm giving this more thought.. Now that I don't have a job anymore, in preparation for being a full-time student, I am wondering if going with the Smart fortwo as the shell would be a good decision considering I have a rolling chassis of my electric project car in the garage. Money isnt the big...

I actually started back in december because it was relatively dry.. but I really wanted to dodge the hot sun - especially since that wall is west facing, although less daylight hours means less outside work.. I have the rest of that wall to resheath (+2 windows) and a longer wall with 4 windows to d...

Today is my last day of work.. School starts in 3 weeks.. Still a ton of house work to do. I replaced the sheathing + windows of the oriel (sort of like a Bay window, but cantilevered up a story).. so I made good progress given the longer US weekend, but all that happened with the flow bench was tha...

I see wave forms and comments about printf but I don't know what they mean. I'm not sure if my understanding of those comments is an issue or not. I suspect you're making good incremental progress, and you seem to have a plan that's allowing you to keep making the progress. the debug printfs that I...

Yup, it was the debug info.. specifically the printf I was using which uses a debug serial port.. obviously it is a blocking call DS1Z_QuickPrint1.png I made an output of when the rotary encoder was detected(purple).. upon seeing the issue with the hall effect on/off, I commented out the prints and ...

Didn't do anything over the weekend, because of life.. Story of my 2018 so far. I was wondering when you would stumble into my thread.. Was treating it as a dialog between only myself and kb1gtt for a while :) The more the merrier. Anywho.. The current effort is the timing of the SCV in relation to...

Didn't do anything over the weekend, because of life.. I noticed I didn't share this image, of a double SCV timing graphic. Comes from a denso service manual. EDIT: maybe HP2 not relevant for this vehicle https://www.denso-am.eu/products/diesel-components/common-rail-suction-control-valve-scv if I h...

So, I was able to rig up a stepper via SmoothieBoard getting G-Codes through the serial interface from the KL25Z.. and it was actually able to turn the HP pump once I fixed alignment issues with a u-joint socket.. DSC_5121.jpg .. Somewhat .. It was able to turn it while the rail wasn't "on"...

I was able to program a UART serial port on the KL25Z to interface with the SmoothieBoard and send G Codes.. (took most of the night because I am fairly new to it all) only a few configs needed to make a "standard" "mm"/rev and feed rate.. G1 X10 F6000 is one rev @ 600rpm.. so ch...

Nice wood work. hah! this was one of the biggest hack jobs I've done.. just glad to have everything on hand, including a hole saw big enough, to do it.. there is a gap at the top of the stepper mount to the other filler block because it was thinner than the 3/8" OSB and I didn't want to cut th...

Stepper mounted.. very stable and glad I wont have to deal with the hand drill anymore.. That hall effect sensor will be (no longer flapping in the wind) picking up a magnet on the socket, likely held in place w/ electrical tape.. the shaft of the stepper is not ferromagnetic otherwise I would have ...

Another logic part of the puzzle.. Knowing that 0.5cc are injected at 100% (two plungers so twice per rev, but unknown when to TDC this happens just yet.. but it is timed).. What if I only wanted 75% of that 0.5cc? the plungers of the HP pump are driven by a concentric (square or triangular based on...

Got some misc electronics like hall effect sensors and whatnot to "know" when the pump as at a TDC or similar.. A bunch more math ahead and in the near future.. The initial goal is to determine the volume of the high pressure side. Common rail, lines, etc.. Because the high pressure inject...

Double checked in the service manual. the HP pump is timed w/ the crank (1:1 ratio on the timing chain) likely to inject into the rail right before or during an injector delivering fuel to the cylinder.. 2 injections of fuel per rev of the pump/crank. I wont be able to simulate that, nor RPM guidanc...

no worries, please excuse every step being dumbed down..

again, interesting it directly related to PSI instead of atm/bar or kPa.

good progress indeed.. next steps will be proper regulation.. and then the injectors!

I think most of my error is the physical delay of expectation when the gauge hit's the desired number and me pushing the stop button on the scope.. there isn't much reaction time and no regulation based on the two solenoids (one 100% on, the other 0% on).. but yeah, to get R2 for linear up that high...

I believe I have the equations.. went from 0 to 10k psi.. finally figured out a "Decent" way to have my hands on all of the controls (75psi primer pump switch, rail regulator switch, hand drill->HP pump, STOP button on scope, eyes on the gauge as it falls... then flip off the primer pump t...

New adapter came in. (one was wrong, was was right) First impression: Beefy at least compared to the low pressure gauge kit contents - of which I yielded about half of the brass adapters. This is "aircraft grade" aluminum - I would have preferred steel (stainless) - but the 1/8"-1/4&q...

yeah, I guess kitchen was an okay idea afterall.. I am renovating the house and that will be converted into the master bedroom/bath, kitchen - which is currently a wet bar - will go to the first floor (why would you ever have a kitchen on the second floor? it is sort a duplex) DSC_5089.jpg Anywho, I...

Fixed.. Will hold 80 PSI blocked off before the HP pump. When attached, it seems to get to 75psi, and will bleed down slowly when not fed (HP pump and feeder pump not on). HP pump seems to work at 10psi(not well and not below). When the HP pump runs I can imagine the pressure will drop from the 75ps...

What's the phrase?

FML...


forgot to reinforce a clossed tube, blew at 65psi.. cleanup was a mess(me, windows, fridge...... why am I doing this in the kitchen?!?) - rewarded myself with some beers at the pub for said cleanup, time to try again?

.. Ooopse

Crowsfoot "wrenches"(?) arrived, was certainly able to torque the lines I touched to proper 21 ft-lbs.. can't imagine trying to build up any kind of pressure in there with how loose one of the lines I messed with was, but as I said, a crescent wrench can only do so good, especially when yo...

Yes. I am getting variation of voltage from the purple and green line (they appear to be opposites, purple will lower with increase of pressure and green will increase). The scope, ch2 & 3, are connected directly to the signal lines, with a ground strap from the probe on ch2 connected to the neg...

Since I goofed around with the fuel lines (service manual states to replace with new, I think that may only be for the idea of contamination and not really the seating) I needed to order a set of crowfoot wrench heads.. my crescent wrench will not do.. also getting a 15k psi WIKA gauge to map some o...
