Diesel Fuel Injection System Help Desk

[Dieseldude]

sir dieseldude, salamat po an andyan ka.
meron po ako problema sa 2008 dmax ls 4x4 ko.
may time po na kinakapos sya sa power.
prang napuputol po yung supply ng diesel.
minsan po pag mabilis ang takbo, nabibitin.
minsan po pag mabagal ang takbo, namamatay.
ano po ang dapat kung gawin?
magpalit na po ako ng fuel filter, at sinunod ko rin ung instructions sa pag bleed sa manual.
dadalhin ko na po sana sa casa, pero hintay ko po muna advice mo.
maraming salamat po. god bless you. tsup.

Sa experience ko, may problem ang high pressure supply pump. Mas mabuti kung ma scan muna ang Dmax mo para matumbok ang problem.

Kung under warranty pa yan, dalhin mo sa casa. Kung out of warranty na, pwede ma repair yan ng diesel workshop na may common rail test equipment....... cheaper and faster pa.

Another diesel noobie here,

How do you check and adjust the timing of electronically managed diesel engines? Can it be done outside the manufacturer's casa? or is the job left to them?

just wondering, TIA.

TIA.

Your question is quite broad. What specific engine make and model are you referring to?

[Negus]

for example, those new toyota d4d engines, I think they are electronically timed? I'm talking about those diesel engines which uses non-mechanical fuel pumps.

edit: got answers from another site.

I guess one can only adjust the timing by playing with the ECU for these types of engines.

Toyota D4D injection timing is electronically controlled. Timing map is stored in the ECU, and is variable. The ECU looks at many operating conditions like, coolant temp, throttle pedal position, engine rpm, etc, and adjusts timing as needed by the engine.

sir dieseldude help naman sa montero sport ko ... 2.5 gls a/t..

pag inapakan ng konti ang gas pedal (papuntahin lang ng 1k RPM) aakyat sya then bigla magdrop sa normal na 800 kahit nakaapak ka pa sa pedal. as in nasinok 8 out of 10 times mangyayari to... nung ckeck sa computer (MUT) wala naman lumabas na problem sa SCV nasa 175-183 ang unit nung SIQL kaya wala daw sa SCV... wala naman nakita na contaminant sa fuel tank at sa line..

ano kaya cause nito? nag lalaro din pala paminsan minsan ang RPM +- 100

kita nila lahat to pero wala silang clue...

nextweek try ko dalhin sa citimotors makati para icheck daw ang commmonrail...

natry ko na pala shell, petron,caltex,total.. ubos from fulltank to empty every brand.. maayos naman mga station na kinargahan ko

nakakainis lang sa stop and go na traffic pag umabante ka ng konti pumupugak ang sasakyan e,,

tnx!

as in nasinok 8 out of 10 times mangyayari to... nung ckeck sa computer (MUT) wala naman lumabas na problem sa SCV nasa 175-183 ang unit nung SIQL kaya wala daw sa SCV...Ano ba yung unit measure ng 175 - 183? And at what rpm was the test conducted?

wala naman nakita na contaminant sa fuel tank at sa line.. Good.

ano kaya cause nito? nag lalaro din pala paminsan minsan ang RPM +- 100. kita nila lahat to pero wala silang clue... Mabuti sana kung meron test pump assembly ang Mitsubishi. Palitan nila para ma-verify.

maraming salamat sir dieseldude sa reply!

sinabi ko na din dati sa service adviser na baka sa sensor ng pedal ang problem pero snob nya lang ako... pagpunta ko uli sa ibang service sasabihin ko..

hindi ko alam anong tawag sa unit na yun hehe pinakita lang kasi sakin na normal yung ganun na measure..

update ko kayo pag nadala ko na... thanks again sir!

Ok. We'll be waiting for your update. Bye....

dieseldude, here's another problem of mine. every morning when i start my pick up, it's idling like it's running out of fuel, but after a few seconds, the idling will be normal again. this is consistent every morning for the last 2 weeks. one of our mechanic told me that it could be the injection pump check valve. He said that the lines from the injection pump going to the injector maybe loosing fuel overnight because of a faulty check valve and that would explain why my pick up is "PALYADO" every morning when i start it,
what do you think is the problem? need help.. thanks in advance for the reply.

I got a 2005 Toyota Innova J D4D with a turbo timer... what does a turbo timer really does? is it true that it helps to cool your engine as you switch it OFF, coz I notice that everytime I turn off or remove the key from the car, the engine is still running and have to wait for the timer to stop or go to 0...
if it really has no purpose, can I uninstall it from the car?
why is it named turbo timer, does it really give you an extra push (speed) on the car?
sorry if it might be off-topic, but ive only been noticing this into diesel engine automobile, since I havent seen one on an automobile-gas with a turbo timer.

tnx...

Sir Dieseldude,
This is quite a simple question, I'm a newbie on diesels anyway..But what is the reason why diesel engine vehicles only have a maximum of 6k rpm in their tachometer (I think 4.5k rpm pa lang, start na ng redline)? While the gas engine has 8k-9k+ max rpm?

Thanks po!

He said that the lines from the injection pump going to the injector maybe loosing fuel overnight because of a faulty check valve and that would explain why my pick up is "PALYADO" every morning when i start it, Your mechanic could be right. I suggest that you manually pump the filter before doing a first start in the morning. If performance improves, then the check valve may be leaking fuel back to tank.

what do you think is the problem? need help.. thanks in advance for the reply.

I got a 2005 Toyota Innova J D4D with a turbo timer... what does a turbo timer really does? It cools down the turbo before shutting down the engine.

is it true that it helps to cool your engine as you switch it OFF, coz I notice that everytime I turn off or remove the key from the car, the engine is still running and have to wait for the timer to stop or go to 0...
if it really has no purpose, can I uninstall it from the car? You can uninstall it. Toyota never put one in anyway, and I wouldn't put one in my car too.

why is it named turbo timer, does it really give you an extra push (speed) on the car? No it does not.

sorry if it might be off-topic, but ive only been noticing this into diesel engine automobile, since I havent seen one on an automobile-gas with a turbo timer. It can be installed on both gas and diesel engines.

tnx...

sir dieseldude, i have a 2001 hilander sl and it emits too much white smoke when accelerating at every gear. the engine doesn't consume oil and city driving fuel consumption is 12 to 13 km/l, so i ruled out that it has a loss compression. but the oil dip stick shows some white smoke but our mechanic said that it is normal because it doesn't spits oil. could it be a faulty injector?

i have the injector cleaned at a calibration shop near us but excessive white smoke when accelerating is still there. pressure showed +-170 something on all injection nozzle and the mechanic said that it is normal. but i'm unsure of what he said because on the plate on the engine bay indicates it should be 185kg/cm2.

can i please have an advise?

thanks in advance for the reply

tnx for a straight forward answer on my inquiry

yet regarding this inquiry dont I have on my engine to help cool down the turbo before it shuts down?
what I mean is that, havent my (toyota) manufacturer thought of this, for buyers wont not need to put this aftermarket part on their car...

anyway my car is an Innova J d4d

tnx again...
