CRDi Maintenance Questions & Other Discussions [Thread]

[mambo]

Kasi yung mga dating diesel pag after 10 years parang pangit na takbo....


Not only that, I saw a CRDI particularly tucson at pag bumuga ng usok akala mo factory. And just wondering, bakit option ang CRDI sa atin? Why not encourage going "green"? Di ka man lang makakalabas at maglakad-lakad na di mangangamoy usok!

Again I have to agree with Dieseldude. HUEI on the 4jx1 is significantly different from Bosch and the rest of the OEMs because it uses an engine driven oil pump to feed high pressure oil into the injector to pressurize the fuel. A high pressure pump is not needed (CP3 common rail pump). Fuel is fed to the injector at a relatively low pressure (50-70psi) and a solenoid controls the high pressure oil going into the plunging mechanism to ramp injection pressure up to 21,000 psi. Huei was developed by Caterpilar and used on the 7.3L Power Stroke V8.

t2ern is very a patient person, relaxed and systematic. He will need support before his patients runs out and burns the unit out of disgust. Natuwa nga ako when he posted about needing help. A 4jx1 that we can actually examine, evaluate and tinker with the permission and full support of the owner.

If successful, you will make a lot of people happy while earning good bucks. How does this sound?

Sounds good!

tanong lang po... what is ECU? anong function nito?

[pup2]

Sana nga maganda mga CRDI pag tumagal...

Kasi yung mga dating diesel pag after 10 years parang pangit na takbo....

Never pa kami bumili ng diesel na sasakyan

Depende sa gamit at kundisyon, kahit naman sa gas engine puwede mangyari ito. Technically, thicker steel is used for the bodies of diesel engines (due to the higher compression ratios) so it has the potential to last even longer than gas -- though injectors will probably have to be maintained more (due to higher pressures). I think this is the reason why there are a lot of REALLY OLD diesel trucks going around as well as a lot of injector/calibration shops and what not. Tama ba yung last dieseldude?

Kaya nga mas madalas ang turbo diesel kesa sa gas na diesel -- puwera lang ang sa FXT ko. hehehe. Pero with the introduction and anticipated further improvements in CRDi, even gas stalwarts like Ford and Subaru and Porsche (yata) are coming out with them. Biro mo, mas matulin na, mas fuel-efficient pa. Talo pa nga yung mga hybrid na di masyadong OK eh.

Teka, si OTEP din madaming alam sa diesel ah. Yoohoo. Saan ka na DOC?

Electronic control unit is the brain in electronic engine management and it function like it. The unit monitors, actuates, coordinates, warns, derate or even shut down the engine.

*Sir Dieseldude,

You stated na iba ang common rail system ng Trooper sa ibang vehicles. Trooper lang ba ang may unique na common rail if given the same year? What about CRDi's in 1998 or below?

Yes, the Trooper's CR system is unique, and we have never seen a similar sysem installed on other vehicles here before or after 1998. This system is quite popular in the US on Ford and Navistar engines though.

Not only that, I saw a CRDI particularly tucson at pag bumuga ng usok akala mo factory. This is not normal. Something is probably wrong with it.

And just wondering, bakit option ang CRDI sa atin? Why not encourage going "green"? Di ka man lang makakalabas at maglakad-lakad na di mangangamoy usok! We have no choice on this. CRDI is here due to it's comformance to latest emission standards. CRDI is fast replacing all traditional diesel injection systems as it is supposed to be a "greener" engine. The traditional injection pump has become a thing of the past.

Hi PUP2,

Depende sa gamit at kundisyon, kahit naman sa gas engine puwede mangyari ito. Technically, thicker steel is used for the bodies of diesel engines (due to the higher compression ratios) so it has the potential to last even longer than gas -- though injectors will probably have to be maintained more (due to higher pressures). I think this is the reason why there are a lot of REALLY OLD diesel trucks going around as well as a lot of injector/calibration shops and what not. Tama ba yung last dieseldude? Tama ka pup2. And not all diesel workshops can work on CR as the old calibrating machines are not capable of testing common rail systems. Diesel workshops will have to train and invest on new CR equipment if they would want to go into this field.

...... with the introduction and anticipated further improvements in CRDi, even gas stalwarts like Ford and Subaru and Porsche (yata) are coming out with them. Biro mo, mas matulin na, mas fuel-efficient pa. Talo pa nga yung mga hybrid na di masyadong OK eh. Very true. CR is a very good system which we just have to be more familiar with.

Q lang, Dieseldude.

I have 2 crdi vehicles right now, a 2.5 strada and a 3.0 everest. Mabango ang exhaust ng strada, hindi masakit sa ilong, pero sa everest, parang ordinary lang. Pareho namang silang hindi mausok. I also fill them up with the same diesel brand. What could be the reason for this?

[niky]

I've seen new Hyundais, BMWs and Toyotas smoke... I think it has a lot to do with fuel quality in this country... not with the technology itself.

RE: ECUs... while it can happen, and often does, ECU failure is quite uncommon...

yan din ang question ko wayback sa thread ko noon but unfortunately medyo napagtawan Anyway…. To follow up dieseldude, lalo na ang isuzu non crdi’s but direct injection naman, bakit talagang masakit sa ilong kahit di maitim? while yung mga 4d56 and other indirect injection parang init lang ang labas? Thanks

[drey]

Hmmm... Di kaya maraming nagkaka-asthma dahil sa diesel na ganito ang usok o talagang lahat ng diesel?

[4JGtootsie]

Sir Niky add ko lang.

ECU don'ts

1. don't try be clever and open it
2. never cut battery while in ignition
3. never use 12 volt trouble lights/probe
4. don't drop it
5. only use relays that is oem to that ECU

anybody wants a 4jx1 engine with computer box? baka gusto nyo gawing testing ground.

Each engine manufacturer has it's own preference on combustion design like compression ratio, injection timing, fuelling, air boost, etc.

This accounts for the reason why each make & model has it's own characteristic exhaust scent, noise level, and fuel consumption curve.

By law, these new diesel cars would not have been allowed into the country if they didn't conform to our emission laws.

Smoke could be caused by so many factors:

1. As Niky posted, poor quality fuel could be a reason. This has to be validated though.
2. Poor engine maintenance.
3. Engine modifications.

i have starex 01 model.. and last december had it registered.. during the emission testing the guy really reved the engine really hard.. this emissions testing center is the one near the LTO tagaytay...i think the guy was really trying to fail my starex.. but there was no hint of smoke at all.. i should have taken a video of it. the guy really reved up the engine a few times..but no smoke at all. and the results was 0.10 on the emissions machine.. my question then is how far ahead is the emissions of a CRDi engine compared to my TCI starex? is there a totally different grading system?

[Dieseldude]

Hi Cocoy,

Yes there are various levels of emission standards. If my memory serves me right, Euro 2 is our country's present emission standard. Some countries use Euro 4 and/or 5 which are a lot stricter.

Whereas the TCI is Euro 2 compliant, most CRDI engines are Euro4 compliant.
CRDIs will definitely be cleaner burning engines.
