CRDi does it really live-up to its expectation?..mula inilabas yun??

[dbuzz]

CRDi - Common Rail Direct Injection
(history: 1994 Fiat Group collaborated with R. Bosch to enhance and complete injection systems for diesel engines -outcome: CRDi)

Ito ang bragging nila noon ng sumikat yun ng 2005 compared to conventional diesel engine:

>>> 30% more powerful

>>> 70% more torque ..... (aha!!)

>>> Lower fuel consumption 30-35% more mileage..... (24km/L daw CRDi)

>>> High fuel effeciency

>>> Improvement in drive quality (malabo 'to)

>>> Far quieter due to its hydraulic accumulator or "rail" that reduced noise, vibration and harshness (NVH) and i qoute "more than matches that of a gasoline engine".

bottom line: ITS FAST, QUIET AND ECONOMICAL

well, is this so????..after sometime in the road now dito sa atin??

It's definitely not more powerful. Look at the engines of the new Pajero (4M41) and Patrol (ZD30). The power and torque output did not improve when both engines were equipped with CRDi.

I think that was because they already had direct injection to begin with, hindi nga lang common rail. The 4M41 has been going under the Di-D badge since the launch of the Gen3 pajero some 8 years ago.

[lolo pepe]

the CRDis are fuel efficient.

BMWs & MBs have been equipped with CRDi engines for quite sometime now, especially that their customer base in Europe has a great demand for diesel engines.

[Radical!]

Yes the CRDi lives up to its promises. The improved NVH to me makes a world of difference from the first-generation diesel engines. Driving our workhorses of yesteryear (Nissan Pick-up and Isuzu Highlander) got me easily tired due to the diesel clatter and vibrations. 'Liter for liter', the CRDi engine rocks!

[niky]

You can't base it on just one or two engine models. Look at the 4D56... it's gained a lot of power through the use of CRDi... the DiD version is pretty good, while the Hyundai CRDi version is even better.

In my experience CRDi engines are much quieter and smoother, with a better "pull" through the rev range than previous iterations of diesel. They're definitely more powerful, pound for pound, than older generation turbodiesels of the same displacement... yes, you can tune an older diesel for the same power, but driveability will suffer, and it still won't be as revvy as the CRDi.

As for fuel economy... that depends. Use more power, use more fuel... the Innova's D4D only gets around the same economy as the Crosswind's 4JA1... it does make 15-20 more horses and it definitely runs smoother, but that's disappointing. The Fortuner 3.0 D4D drinks like a sailor when you put the pedal to the floor, too.

The Hyundai Starex CRDi engine drinks less than the turbodiesel before it, but it's not spectacular.

But I guess this all depends on driving style and the specific engine-car combination we're talking about... the Accent, from dealership feedback from owners, gets 25 km/l in mixed everyday use. That's nowhere near C!'s 38.8 km/l, but it's still damn good...

[OTEP]

It's also worth mentioning that the more precise fuel delivery afforded by CRDi is also a factor in lessening emissions.

Of course if you used crappy fuel or neglected maintenance, that's another story. But all things being equal, present CRDi engines are designed to meet a stricter set of emissions regulations than their ancestors.

[XTO]

mabilis at tahimik pero sa durability at life-span medyo questionable pa.
sigurado mahal ang repair and maintenance.

[kpy555]

I believe the CRDi will, as I also believe car engineers and manufacturers around the world will continue to improve it.

We did not have any diesel-engined car for more than a decade (the last one we had was the Mazda B2200), and it is just this year that we got a Santa Fe CRDi. It really changed my perception of diesel engines nowadays, and I'm pretty happy with the performance.

[niky]

From my experience with CRDi engines.....

BMW Diesel: 220 HP 500 NM torque from a stock 3 liter CRDi Diesel - 240 ++ kph top speed and acceleration to the century mark in a consistent 7 seconds (though with all the torque smashing you against the seats it somehow feels faster). My FC in City driving during heavy heavy traffic is 7 km/l. In terms of tuning, I recently got the chip / harness to upgrade it to 275 HP and 630 NM torque (26% increase from a $300 product) and will be installing it over the weekend ( http://www.chiptuningdirect.com ). It's a super engine and has made me a firm believer in CRDi technology. And my diesel engine isnt even the newest iteration from the Bavarian company as they already have a twin-turbo version of my engine which is even more powerful and drivable.

Other examples which you can read about on the board are the fabulous Hyundai CRDi engines of the Sta. Fe and the Vera Cruz, the CRDi of the Getz and Accent. The Ford CRDi Duratorq engine in the new Ranger / Everest is also a gem.

Hey! Bring it over to Speedlab and have it dyno-tested... before and after... I'd like to know how that thing works out. We're getting a Santa Fe soon, and I'm looking into some chip-tuning options for it.

[louchua]

Crdi's are definitely more smoother, quieter and torquey than previous generation diesel engines. Take the new 2007 Dmax CrDi for example. We had the older model and there was diesel shudder all over. But with the 2007 model with the iteq engine, you can really notice the difference. Also the same with the 4D56 of the new Strada compared to the 4D56 of yesteryears.

[niky]

Nope... a customer. You could do it there, at autotechnika, at autoplus, or wherever... I just want to know how much it'll give... burning curiosity, eh...

Dyno-test? What does it do? Can somebody enlighten me briefly?

[Horsepower]

But those are ancient engines.

CRDi engines are best built from the ground up, not just modded.

[oldblue]

from 2k2 - 2k6:

1. i drove a 2.0L 1st gen CRV 4WD M/T - gas guzzler na siya para sakin at 5km/liter

2. i drove a 2.2L 2nd gen Strada 4x4 M/T - thrifty sa fuel pero parang tangke naman sa bigat i-drive. nanakit ang likod after a 1 hour bumper to bumper rush-hour traffic. hindi ko na kelangan mag-gym sa hirap eh

=====

then came the CRDi:

automatic na, responds like gasoline ang accelerator, and i dont go below 8km/liter even in bumper to bumper rush-hour traffic.

so did it meet my expecations? definitely! tipid, convenience and power all 3-in-1 coffee

Nagkakatalo lang naman yan sa system operating pressure. Baka naman low pressure system pa rin gamit nila. Alam ko kasi, higher operating pressure will yield more engine power. Yong bagong Pajero 3.0 DI-D is 160hp lang samantalang Sta.Fe 2.2 CRDI is 150 hp. Pag CRDI, magaling talaga siguro pag gawa ng BOSCH.
