looks like mas superior talaga ang crdi systems ng mga koreans, it seems like theyre leading the way when it comes to diesel technology

you guys should watch out for the new crdi evgt-r engine of the santa fe, it develops 200hp from a 2.2L engine with 6 speed tranny

if crdi is to d4d/DiD, meron ba vgt or variable geometry turbo ang mga japanese diesels released locally?

Meroon na rin sa pagkakaalam ko, yung 3.0 D4D naka VGT na rin pero VNT lang tawag nila. Yung 2.5 ng Nissan Navara naka VGT na. Kahit Ford, yung 3.0 at 2.5 tdci engines nila naka VGT na rin. Hindi lang ako sure sa iba pero sigurado ako hindi lang ito yung mga naka VGT sa atin.

looks like mas superior talaga ang crdi systems ng mga koreans, it seems like they're leading the way when it comes to diesel technology. This may be true for Hyundai. This company has long been in the diesel industry: huge diesel tankers, diesel engines for trucks, construction, mining, generators, and diesel cars of course.

On the issue of diesel quality here.. i think it has nothing to do with it. wala kasi problema ibang car manufacturer.. Correct. But why do Denso systems have more problems that Bosch's.?

maybe because Bosch are 30 years ahead in making CRDi than Denso. nabasa ko lang sa wiki :D

Hyundai is using Bosch's?

myth lang yun sa kanila while a lot of people are actually experiencing it first hand. they won't mention the worse problems such as engine chocking and innovas/fortuners stalling in the middle of the highway

We also experienced this dreaded D4D problem in our Toyota Hi-Ace. Buti na lang the problem showed up before our trip to Legazpi city kaya meron pa time na magpalit ng sasakyan.

In our motorpool, we got 2 D4D Hi Ace and 1 D4D din na Innova. Yung sa Innova, nagpakita na ng signs ng black smoke emission. Yung recent encounter is the Hi-Ace. 3 years na yung hiace namin and it suddenly showed signs of erratic idling hanggang mamatay yung engine.

Tsk tsk I really hated toyota for this. the fact that they never saw it as a problem is indeed a big problem. If it is indeed a myth, hindi sana ganito kadami ang nagcocomplain about their units.

maybe its a sign na their not good in making diesel engine. or denso is not experienced enough compared to bosch

[Dieseldude]

From what I have seen, Denso seemingly has a design defect on the suction control valves of their first generation supply pumps. This has caused a lot of problems for engine manufacturers which use the same system.

I assume that it is for this reason that Denso has come up with a redesigned supply pump with an improved suction control valve.

I believe that local car distributors, with the aid of government should compel Denso to replace these problematic pumps with their upgraded pumps free of charge, and whether the vehicle is in or out of warranty. This is how consumer protection works in other countries.

my 2005 Toyota Innova J D4D fuel system warning light just turned ON suddenly; its an indicator that has a drawing of a fuel pump with dots on the bottom; it is an indicator just beside the fuel gauge; sorry dont know what that sign is called; am I just going to follow what is seen in Page 282 of the manual - Draining fuel filter water? what are the causes of that sign-fuel system warning light?

juz a follow up: what does D4D stand for?

tnx a lot...
