Diesel engines: Di-D vs VGT

[zaza.altis]

good day to everybody . just want to get your expert opinion re this matter. Di-d from mitsubishi vs VGT from hyundai.
1. Which is more advanced/ modern?
2. more fuel efficient?
3. how do each one work? both are crdi right?
4. on the long run which will last longer?

thanks in advance. sorry medyo bobo ako sa diesel engines.

AFAIK, VGT (Variable Geometry Turbocharger) refers to a turbo charger and not a proprietary engine technology like Mitsubishi's DI-D or Toyota's D-4D. Pls. see the wikipedia article on VGT.

thank you for the reply but if you were to choose would you choose the one with vgt? thanks

The longevity, performance, etc. of both engines are almost equal. The Hyundai CRDi engine though produces more HP per displacement and can be chipped to produce even more. Mitsubishi's Di-D on the other hand is the more proven one.

zaza.altis * VGT is use to eliminate the turbo lag of the engine..as mentioned by mazdamazda Mitsubishi's Di-D on the other hand is the more proven one. Also, adding to that many CRDi engine claim that their engine has the most fuel efficient, but in real world hindi pala.. you can check all the FC's the vehicle you want to purchase. there so many threads here specially the review on fuel consumption.

Well... consider that both the Mitsubishi and the Hyundai 2.5 are based on the venerable Mitsubishi 4D56... Hyundai's CRDi vehicles in the Philippines have proven generally reliable, despite the poor diesel.

Which two vehicles are you picking between?

As far as i know, Hyundai - Kia diesel engine uses CRDi system by BOSCH... Toyota D4-D system by Denso, dunno for the DI-D of mitsubishi...

Basically, D4D and DI-D and CRDI uses the same principle of common rail and electronic injection..

Robert Bosch Co. is the key player in the development of Common Rail Technology..

[alwayz_yummy]

"crdi-vgt" is way newer than mitsubishi's "Di-D"..2 generations i think. iba ang "Di-D" sa "Di-D commonrail".. kaya iba power ng nasa 3.5 gen pajero than 3.0gen paj,L200, at the newly released montero sport.

pero kung sa power at power at efficiency lang, lampaso ang Di-D sa crdi-Vgt.. for the same 2.5L block, mas malakas power ng nasa starex than sa strada noh.. layo ng difference, even mas malakas pa sa 3.2L di-d!

the only 2.5L na pumantay sa power ng crdivgt ay yun sa navarra 4wd, a 2nd generation yd25-crdi. pero yung 1st generation non-crdi yd25t found on a 1999 jdm serena produces 150ps*4000 and 280NM*1800 already.(may naliligaw na nito sa local converted market ha)

what more pa pag naglabas ang nissan yung 3.0L version nung commonrail nila na based sa non-crdi zd30, lakas siguro nun.

ka nga kahit matrix or getz or accent crdi vgt lang masaya na ako e...pero 100T prenium than the same sub-compact...

^^^ best explanation here idol AY!

Note that on-paper power doesn't always translate to on-the-road power, though... In testing, the Ford Ranger's torquey engines are still the cream of the pickup crop (even against the Navarra)... wider powerbands, kasi. Nissan's new YD engine is rather peaky.

[alwayz_yummy]

i agree, on paper lang maganda basahin mga bigger numbers, iba parin ang test drives.

daing factors nga,e..

like the 2.2l CRDI Engine of Santa Fe, it is punchy form 0-50kph, but lags at top end.....hope to rechip the ECU ( if possible ) for a longer power bond.

but that small engine can match most 2.5-3.0l CRDI of other make.

Kevin Limjoco of C!Magazine chipped his. Says the acceleration times went from around 11 seconds to the mid-9's from 0-100 km/h. But his chip was really expensive. The Unichip will also work for your ride, and at 30,000 pesos, is about half the price of the common diesel chips on the market. The only disadvantage is that you'll have to leave the car at Speedlab for two or three days for installation and tuning, since it's not plug-and-play like the diesel chips... if the plug-and-play option is available for the Santa Fe, it'll cost another 20-30k.

I know the guy, he once dropped by in one of our ebs at Alabang and gave us few C Mags, but he was driving his Merc then. Do you know what software they use?

Thanks for the info Niky.

malaking factor din yung 5 speed AT sa acceleration, fully equipped talaga ang sta fe, 2.2 VGT na plus 5 speed AT pa.

kung fuel effiecieny di kaya mas matipid ang non vgt? kasi at low speeds sisipa agad ang turbo, unlike sa non vgt hi revs lang gagana, kaya sa stop and go traffic mas matipid ang non VGT,

sir niky, chip guru, Ive read most of your post reagrding chips and lpg conversion, balak ko kasi bumili ng chip din for my diesel DID, kaso yung nakita ko hindi yung kinakabit after the ecu, but sa fuel rail kinakabit (plug and play din, no wire cutting), sa engine bay kanakabit sa socket daw ng fuel rail. may difference ba yung ganitong chip ang yung unichip?

to everybody ,

thank you for your reply and comments. this thread is very informative indeed, more power!
