Diesel Fuel Injection System Help Desk

[1902]

i am new to this forum and i have a question on Calibration. i have a 1999 fieldmaster with over 200,000kms with no overhaul so far. i have hard starts in the morning but when i get it running its back to normal. a mechanic said it needs to be recalibrated. (or change the glow plugs)
i read somehwere that diesel engines need to be recalibrated every 120,000kms. so what is the correct approach?

hello dieseldude!

planning to replace the injection pump drive seal dahil may tagas sa likod ng timing gear case. wala nako makitang source ng tagas kundi sa injection pump lang.

isuzu 4JA1 naturally aspirated. not sure kung zexel or bosch...

tanong ko lang kung kelangan pa rin bang icheck ang injector timing (plunger stroke vs. crankshaft rotation)?

or simpleng salpak lang pupwede na?

kung kelangan e di may rason na akong bumili ng dial indicator kung ganun.

i have no issues so far naman with regards to excessive exhaust smoke, acceleration, etc.

2004 dmax MT 4jh1. Starter cranks strong but engine wont start. Handbrake light lit even with parking brake disengaged. Battery light also lit at key on position. Is the lights some sort of code to identify the problem. Car died on the road while traveling about 40kph.

Mga Sir, ask ko lang kung ilan odometer reading kailangan magpalit ng nozzle tips ng 3L na engine.

[beetlebmble]

Might be a good idea to service the clutch assembly/transmission system also, not that it affects FC, or would it?

After 6 years lol.. got my clutch / pressure covet/ release bearing replace at 278000 km. Aisin for the clutch and Nachi for the release bearing. Ok na ok ang performance. Lumambot din yung clutch pedal. For FC , the mechanic in toyozu suggested na ipacheck nozzle tips sa 300000. If yung spray pattern and leak test hindi na mahabol.. time to get ORIGINAL nozzles na. Sabay na rin papalit sa timing belt

sir dieseldude,

Quick Question lang.

ano ba size ng oil seal (front) nung injection pump ng isuzu 4ja1 NA???

ang nakikita ko sa google sources ay ang sumusunod:

18 x 31 x 6.8 mm atsaka 20 x 31 x 6.8 mm....

yung 20 x 31 x 7 mm meron sa mga auto supply...yung 18 x 31 x 6.8 mm e wala ako mahanap...mukhang nasa kit iyon.

lumalakas na kasi tagas nung harap ng injection pump as evidenced nung mga diesel leaks sa likod at harap ng timing gear case cover.

TY

[Dieseldude]

20 X 31 X 7 or 20 X 31 X 6.8 are both OK.

Our 2-in-1 invention consist of an electromagmetic component and a electrostatic component.

Napansin ko, if after some time, I open the air induction hose, I notice so many dust clinging to the needle sharp transducers. Its difficult to brush this dust because they are negatively ionized. Baka pwedeng lagyan ng maraming metal mesh para gawing air intake cleaning system, don't you think? Thanks for this thread.

[Dieseldude]

Since original car manufacturers don't produce a similar product for their cars such as yours, I don't see a need for it. A good intake air filter should be sufficient. It will also be easier to clean and/or replace.

Meron bang 100% effctive air filter? Bakit pagbukas ko ng mga engine na nakabitan namin ng device/s. kapal na dust. kapit na kapit dahil neg ionized. "Air cleaner na, fuel saver at engine enhancer pa!" hehehe thanks sa thread mo.

No, walang filter na kaya ang 100% filtration. Hindi ko pa nakita ang device mo, so hindi ko alam. Pwede mo ipa test yan thoroughly, apply for a patent, then sell your product to a car manufacturer.

I fully agree with Sir Dieseldude that there is no product that can provide 100% filtration. Besides, this is quite subjective as it depends on what size of particles you want to filter out and what is your objective. For vehicle application typical air filters are rated between 20-40 microns. Particles that cause most wear on rings and bearings are below 10 microns. There are highly efficient filter media that can handle smaller particles. They come in bigger sizes to compensate for the higher restriction and still deliver the air volume required. If you go for it you need to do some mods on your air intake box. I am interested to know more about your 2-in1 invention. If that can reduce the dirt for passing through the OEM filter that is worth looking into. You can PM me.

Fuelubecare, everytime I open the air intake hose to measure the voltage on the electrode/needles, i notice that the needles is/are full of dust which had been attracted. It is an easy modification to increase the surface area of a wire mesh to trap more dust. Kailangan ang removal ng wire mesh para madaling ilubog sa gasolina o special cleaner. Sobra ang kapit ng dust sa electrodes; hindi pwedeng i-brush dahil may attraction between the neg charged electrode and the neutrally charged dust. Btw, the voltage on the electrode is -500v to -1kv. Increasing it to a little less than -3kv may attract more dust.

Rmember that this dust particles ay ang mga nakalusot sa air filter, so the dust collection mode of the ES device will only augment the air cleaning function of the main air filter. Marami-rami rin yon, baka makatulong in prolonging engine life. Nasa proto pa lang ang device namin pero effective in collecting dust particles. Pls see the device * nuvisysdotblogspotdotcom. Tnx

Dieseldude, may patent application na kami as an electrostatic fuel saver but the dust collecting mode na idea ay nakuha ko sa thread mo. Pwedeng mag-apply na naman kami ng panibagong application kahit na i-extend lang namin o lagyan namin ng specially designed wire mesh which is connected to the neg output of the ES device. Galing ng idea mo bro, i-implement namin ito.

Our biggest problem now is that last month, an Australian chemist saw our product and possibly our blogsite and he gave us P75K to develop it. Maybe this month he will add another P300K dahil he is convinced about the efficacy of our device/s. Di lalo na ngayon kung ibalita namin ang dust collecting mode as an added bonus.

Medyo natabangan ako sa mga negative responses of some TS, kaya nag-lie low ako. Syempre, kailangang mgsipag-sipag ako ngayon dahil sa Australian Chemical Engineer na gumising sa akin. This month, ipatest namin ang device/s sa speedlab, before and after installation. I'll post the results on this thread (good, poor or bad). Ciao

Sir Dieseldude, are you still here?

Yes I am still here.

1. How sensitive yung delphi injector ng hyundai starex?

2. engine wont start after replacing 4 injector washer, bakit po nasira agad yung injector ?

[Dieseldude]

Delphi injectors are ok. We have had no problems with them.

Why do you say they are damaged? Have you had them tested? We can test those injectors

[simple man]

I would like to help! Throw in your questions regarding problems with your fuel systems (injection pumps/ injectors/ turbochargers/ electronic systems/ etc.....) Then you guys take it from there...................if I can be of help, why not!

sir pacncya po nakisingit na ako magtanung lang sana ako regarding sa akin pong sportivo model 2010, mahina kasi siya pag paakyat lalo na sa mga matataas na lugar, tapus pag sa patag naman po 80 to 90 kph lang kahit sa nlex or slex ramdam ko umiiyak na. pinalinis ko naman na ung water separator tapus pinapalitan ko na yung fuel filter kasabay ng change oil .anu po maipapayo ninyo na gawin ko...

[Dieseldude]

Sa palagay ko, dapat ibaba at ayusin ang injection pump.
