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

[ranger34]

Hyundai, Kia, BMW, Volkswagen and Audi uses Bosch CRDi. Ford uses Bosch CRDi for the Focus, Jaguar vehicles, Mazda vehicles, Land Rover vehicles, and other Euro market vehicles; while for the Ranger and Everest, they use VM Motori's CRDi. For the SuperDuty pick-ups, they use Navistar's CRDi system under the PowerStroke name. I think maybe they are going to use Bosch's CRDi for the upcoming Expedition CRDi.

nagtataka nga ako kung bakit mas malakas ang engines equipped with Bosch CRDi compared sa Ford Ranger Duratorq CRDi engines with VGT pa. yun pala hindi Bosch CRDi ang Ranger.



from common rail encyclopedia:

Ford introduced a new 2.5 L version of the Duratorq for the Thailand-built 2007 Ford Ranger (J97U). It is a 16-valve DOHC engine of the VM Motori 2500 cc engine, with Bosch common-rail direct injection and a variable geometry turbocharger. It produces 143 PS (141 hp/105 kW) and 330 N·m (243 ft·lbf).[1]

[edit] 3.0

A 3.0 L Duratorq similar to the 2.5 is also used in the 2007 Ranger as the top of the range. It produces 156 PS (154 hp/115 kW) and 380 N·m (280 ft·lbf).

from the post above, the new Ford Ranger is equipped with Bosch CRDi. but still i have the same question - how come its power output is still not at par with the CRDi engines of Hyundai that are so similarly equipped? meron pang VGT ang Duratorq engine niya.

no offense to Ford Ranger owners...curious lang po talaga ako.

Puede pong reason dyan eh, siguro, nilimitahan talaga, maybe for emission purposes, fuel efficiency, engine durability, smoothness (less sound & vibration),etc. I've read somewhere before na ginagawa yan nung ibang manufacturers, especially sa gas engines. Di ba kaya nga me mga after market na "superchips" para sa mga specific model ng cars/engines na pag kinabit mo, makukuha mo yung "true maximum horsepower capability" ng engine. Me narinig ako na meron daw ganyan para sa 3.0 D4D ng fortuner, you will get as high as 170+ hp pag ikinabit mo. I could be wrong though!

[lolo pepe]

*vctradingcubao...you have a good point there.

[boybi]

Have anyone tried to dyno test a Hyundai CRDi engine? There's a possibility that the Koreans are overdeclaring the power output of its engines. I've heard before that the Japanese also did it a few decades ago.

DAPAT NGA EH GINAGAWA YAN NG MGA CAR REVIEWS, KASI VERY POSSIBLE TALAGA NA ME KONTING EXAGGERATION DYAN

Engines from the factory are tuned to only about 70% of its maximum performance because of liability issues. Aftermarket chips can tune the engines to only about 85% of the maximum. Engines that are tuned to it's maximum are F1 engines that's why they only last 1-2 races.

So hp and trq ratings would depend on how much the factory is willing to tune their engines, not because they lack the knowhow.

I have one question about hyundai engines. Except for the vera cruz engine, are the rest also made by hyundai or sourced from other engine manufacturers?

May point ka dyan or pwede din na underdeclared HP rating kasi kung titingnan natin, paano na a outperfom ng 2.5 Crdi ng Hyundai/Kia ang mga 3.0Crdi gaya ng sa Fortuner, Alterra, Patrol, Ranger/Everest at Trooper.

I believe they're making their own engines now since they spent a lot money developing their R&D and collaborating with well-known foreign companies. Sa Sorento kasi puro Korean ang components nakikita ko. Though may nag mentioned before dito na may mga starex engines na bago sold sa ibang market with Mistubishi engines on it.

Actually, having driven both Hyundai's 2.5 CRDi (Starex) and Ford's 2.5 CRDi (Everest), I can say this:

Taking into account merely the top-end power is misleading. What is more important is the torque-curve and the "power under the curve". In other words... power from the moment you step on the throttle till you run slap-bang into the rev limiter.

Ford's DuraTorqs are immensely accelerative. They have a ton of instant torque from the get-go all the way to the redline. In fact, in AT mode, they can be awfully jumpy. They're tuned for truck work, so low-to-midrange torque is more important than top-end power. But they do have power... more, in fact, under the curve than other engines rated within 5 hp of their lumps.

Hyunda's CRDis, on the other hand, have a smoother tip-in, and a seamless rush of torque up to redline. They're a bit more refined, but they're not a kick in the pants like Ford's DuraTorqs are. Still, they're the smoothest diesels out there, now, with the best top end power.

Toyota's D4Ds... well, they need some more refinement. Their turbo-engines seem to lack low-end punch, and torque comes on slowly. Great top-end, though. The best D4D I've driven so far is the Hiace's non-turbo lump. Lots of low down torque, perfect for city driving. I still don't get why their 2.5 is so gutless compared to the competition, when their 3.0 is actually pretty good.

Mitsubishi's DiD (Strada) feels a bit down on power compared to Hyundai's similar engines, but it drives the most like a gas engine amongst the CRDis I've driven so far.

Isuzu? Well, I'm waiting to see when their next generation CRDis will come out. They were into CRDi early (with the Trooper), but they're falling behind the curve.

[numbah5]

this is it. it's the future CRDi engine of the expedition.

Ford 4.4 Turbo Diesel
From Wikipedia, the free encyclopedia


The Ford 4.4 Turbo Diesel is the engine Ford is developing for their F-series trucks both as a base Diesel for their Super Duty Line and possibly for the F-150/Expedition. PSA may introduce this engine as the flagship of the upcoming 608 range.

It is to be based on the Lion V6 Diesel and has an estimated power output of 330 hp (246 kW) and 515 ft·lbf (698 N·m) of torque. As with the other AJDs it will have a Compacted Graphite Iron block due to the higher power output.

This engine was first meant for 2010 but now it seems like it will be in the showrooms in Aug-Sept 2008. Production will start in June 2008. A 6.7-liter diesel will follow 6 months later.

Powertrain Plans
Ford readies 6-speed automatics, new engines

By RICHARD TRUETT | AUTOMOTIVE NEWS

AutoWeek | Updated: 07/31/06, 2:54 pm et
DETROIT - Ford Motor Company will expand its use of six-speed automatics and introduce engines that are expected to dramatically upgrade the refinement and performance of its vehicles in the next five years.

Fuel economy is expected to improve incrementally as well.

Ford is focusing its powertrain engineering in four areas: diesel engines for light-duty trucks and SUVs, higher horsepower V-8s for cars and trucks, gasoline-electric hybrids and six-speed automatic transmissions.

Here's what's on tap:

Diesel engines: At year end, Ford will replace its troubled 6.0-liter Power Stroke diesel truck engine after just five model years.

In the first quarter of 2007, Ford's redesigned 2008 Super Duty trucks will be powered by a 6.4-liter diesel V-8 with a state-of-the-art piezo fuel injection system.

Ford engineers have finally resolved most of the 6.0-liter's quality issues, but the change is being made to boost power as well as comply with tightening emission regulations that take effect in January. The new engine will enable Ford to keep pace with General Motors' and Dodge's new diesel engines.

Look for the new 6.4-liter diesel, manufactured for Ford by International Truck and Engine Corp., to deliver 350 hp and around 625 pounds-feet of torque.

For light-duty trucks, such as the F-150 and Ford Expedition, Ford may use a 4.4-liter diesel V-8, based on a smaller engine used by its Land Rover division, beginning in 2010.

how true ba itong latest buzz about CRDI engines na masilan daw sa diesel. eh yun pa namang diesel dito sa atin eh daming halu...
oppss ok what i'm saying is how true is this rumor that according to the latest findings, CRDI engines are fussy on the quality of diesel fuel. i.e. adulterated diesel which is actually rampant here.

[cocoy]

Toyota's D4Ds... well, they need some more refinement. Their turbo-engines seem to lack low-end punch, and torque comes on slowly. Great top-end, though.

I still don't get why their 2.5 is so gutless compared to the competition, when their 3.0 is actually pretty good.

so the D4D hiace is not turbo charged? or not intercooled?

[numbah5]

its already turbo charged, because all CRDi engines are equipped with turbochargers... never heard of one not having turbochargers...

[niky]

My mistake... non-intercooled pala yun, and 2.5.

[lytspid]

heres what is wonderful about the crdi engines unlike the diesel engines before,they can be tuned and although in their stock stages they have more torque than their bigger counter part gasoline engines, with simple upgrades like the ecu or crdi tuning modules,we can unlock the hidden potentials of our crdi,as what ive experience on my fort after installing the crdi tuning module,yuo can readily feel the seat of the pants improvement and un mileage nya mas tumipid ngyon...

[oldblue]

wow Ford Expedition CRDi, suddenly biglang nawalan ng halaga Hummers dito hehehe

ang alam ko D4d lang ang maselan sa diesel e, dahil sa mga choke, pero nasolve naman ito by changing ECUs

[dbuzz]

ang alam ko D4d lang ang maselan sa diesel e, dahil sa mga choke, pero nasolve naman ito by changing ECUs

so lahat ng D-4D toyota engines ngayon ay di na nag cho-choke.

D-4D is what toyota named their CRDI(common rail direct injection) engines.
D-4D = Direct-injection 'common rail' diesel engine
[SIZE=2]D4D = Direct-injection “common rail” diesel engine

[SIZE=1]Toyota’s D4D direct-injection “common rail” engine heralds a new and exciting generation of clean, intelligent diesels. D4D makes use of a high-pressure pump and a common rail (pipe) for supplying all cylinders with high-pressure diesel.

The high-pressure injection creates better fuel atomisation for complete burning and increased power output, but also improves fuel economy. In addition the computer control unit injects a small amount of fuel into the cylinder just before the main fuel load ignites. This “pilot burn” lowers the explosive force of the main combustion process and goes a long way to reduce the noise and vibration formerly associated with diesel engines.
