Hyundai CRDI engine against Toyota D-4D

[diesoline]

How about the CRDi engine of Kia Sorento? Does it have problems with the Diesel fuel here? Baka maselan.

I have a 2004 kia carnival 2.9 crdi and have driven it for over 25000 kms on our "dirty" fuel. i haven't had any problems so far. no smoke belching, no loss of power, no engine shutdowns. if dirty fuel is a concern, i think the solution would be to change the fuel filters more frequently than what the periodic service requires.

i haven't changed my fuel filter yet but i will do it sometime soon after i do a b20 biodiesel fillup.

Well as far as I know, wala pang complaints as far hyundai or Kia CRDi is concerned. Wise the sila ano ( Hyundai/Kia). They might not be using the latest technology sa engine but thats because they studied it first before adapting it to their car so no problems will emerge on their model. Unlike toyota, yeah new technology nga engine nila pero kawawa initial buyers since they will be the one to suffer first since their technology is not yet tested especially sa pinas where diesel quality is not good. Yeah they can sort it out but dami muna suffer. I'm afraid na later on, they will issue a recall and it's going to be a big abala sa D4D owners. Ngayon lang pila na sabi nga ng isang kaibigan natin. My friend use Seaoil " Bioexceed " sa Sorento nya and over 9K ODO never have problems. Baka the fact that Hyundai and Kia are using Bosch components/technology kaya good ang engines nila???

carlove dont love no korean cars hehe

The Innova will still not carry people as well as a traditional van. It is still a 5+2.

Btw, the Hyundai/Kia 2.5CRDi is against the engine of the Hi-Lux 4x4. Not the 4x2.

D-4D High technology, clean diesel[/SIZE]

Originally introduced in Europe in the top selling Avensis range, D-4D is widely recognised as one of the most advanced diesel technologies on the market today. Toyota D-4D engines can now be specified on Yaris, Yaris Verso, Corolla, Corolla Verso, Avensis, Avensis Verso, RAV4, Land Cruiser and Previa models.

Until recently, diesel engines relied on relatively simple technology with a low-pressure mechanical injector delivering fuel to a pre-combustion chamber in the cylinder head, where a single ignition - fired by the intense heat of high compression - takes place.

The system was reasonably fuel efficient but lacked precision and refinement, leading to vibration and noise. Fuel combustion can be incomplete, allowing smoke and other emissions to pass into the exhaust.

D-4D components
Toyota's common rail system makes use of a high pressure pump and intelligent, computer controlled injectors to deliver precisely the right amount of fuel, at precisely the right time, directly into the centre of the combustion chamber. D-4D is above all powerful, robust.

Refined, powerful and clean
D-4D common rail diesel engines offer class-leading performance along with the widest torque band in the market. Either four or six cylinder, turbocharged and intercooled, a variable nozzle turbocharger has been installed to boost power output while maintaining low emissions and low fuel consumption. Torque is boosted at low engine speeds for improved driveability.

The power boost is achieved by controlling the velocity of the exhaust gas inflow to the turbocharger at all times in response to engine conditions. The speed of the turbine depends on the flow velocity of the exhaust gases going through the impeller. The flow velocity of the gas is controlled by the variable vane nozzle.

The computerised engine control unit calculates the optimum turbocharger pressure from a series of engine operating conditions such as throttle opening, engine speed, atmospheric pressure and water temperature. It then opens or closes 11 variable vanes in the turbo inlet manifold to adjust the intake pressure to the optimum value.

The long-term durability of the turbine housing is assured by the use of oxidisation resistant cast iron. The engine block is also cast iron alloy while the cylinder head is light-weight aluminium alloy.

Twin overhead camshafts are driven by a toothed belt which is auto-tensioned forsmooth, quieter operation. Belt life has been maximised to 150,000km for reduced maintenance costs.

The crankshaft pulley is dampened to reduce vibration and drives the V-ribbed belt that powers the alternator. The use of a V-ribbed belt, with auto-tensioner, results in longer belt maintenance intervals and lower running costs. The engine oil filter has also been moved in order to improve access and reduce service times.

Low emissions
All Toyota D-4D engines meet at least European Step III emission legislation and Avensis D-4D already meets Step IV emissions regulations. Potentially harmful gases and particulates reduced, thanks to the improved fuel consumption and more efficient combustion of the direct injection engine. Emissions of the main greenhouse gas, CO2, are cut by around 20%.

Improvements to the exhaust gas recirculation unit (EGR) further cut NOx emissions. A step motor on the EGR valve enables more precise control of quantities and the use of water cooling of the EGR passage lowers the temperature of the exhaust gas, allowing a greater amount to be recirculated.

Twin catalytic converters help the diesel-engine meet Step III emissions. One converter, just downstream of the exhaust manifold, uses thin-wall substrates for faster warm-up while a full sized oxidation catalyst beneath the floor ensures cleaner emissions even at low exhaust gas temperatures.

Precise control of fuel injection is achieved through the engine control unit and a 'drive-by-wire' throttle position sensor. There is no accelerator cable.

Reduced noise and vibration
Toyota engineers used advanced computer analysis (the Finite Element Method) to study noise and vibration throughout the car. It has been reduced to a minimum. The engine block has been stiffened by reshaping the rear surface, with optimum positioning of ribs and by improving the cylinder wall thickness. These measures not only reduce noise but also lead to increased durability.

The air cleaner case has been increased in size to reduce the amount of air intake noise. On the exhaust side, a ball joint between the downpipe and the main exhaust has been used to reduce vibration.

An extra sound proofing sheet in the front occupant footwells and sound proofing felt on the passenger compartment side of the front panel reduce engine noise transmission.

[SIZE=3]Hyundai Introduces New Diesel Engine Technology[/SIZE]
11/8/2004

Most diesel engine-powered vehicles are perceived to be noisy, highly pollutive and have very uncomfortable riding qualities. But diesel vehicles have positive points, too. Apart from the cheaper price of fuel, they produce more torque and are better load luggers like buses and trucks. Besides, they allow higher compression and, in that respect, are better than gasoline on the efficiency front.

Diesel engines are most efficient when the fuel at high pressure is injected directly into the combustion cylinder at the point when the piston is at its highest position.

Here, the compression heats up the air to temperatures above the ignition point of diesel, and there is a contained explosion as the fuel burns in this heated air. The explosion is a fairly violent one and the engine is high on NVH or noise, vibration and harshness.

One solution to this NVH problem is an indirect injection engine. But indirect injection makes and delivers power slower than a direct injection engine, and vehicles powered by such engines tend to be sluggish.

Hyundai's CRDi engine "redefines" diesel technology, says Hyundai Asia Resources, Inc. (HARI)

In a statement, the company said the CRDi -- abbreviation for Common Rail Direct Injection -- engine was developed by Hyundai with US-based Detroit Diesel using the system developed by European carmaker Fiat in 1997.

Common rail diesels have been doing duty in some luxury cars in the market, but this is "the first time it is being made available in the Philippines in this price range and in this vehicle category," HARI said.

The CRDi technology makes the diesel engine run like a gasoline-powered one. "It's fast, quiet and economical, while maintaining the diesel engine characteristics of higher pulling power," the company said.

In the CRDi unit, a tube -- also called common rail -- connects all the injectors and contains fuel at a constant high pressure of 1,350 bars.

To do what the indirect injection engine does, the CRDi engine squirts a small amount of fuel into the engine before the actual charge and another one afterwards.

The high pressure in the common rail ensures that when injected, the fuel atomizes to a very high degree and mixes evenly with the air, thereby leaving little unburned fuel and making very clean exhaust gas.

Engine pressure, fuel quantity and injection timing are controlled electronically. The injectors have variable control heads which allow a "very precise" dose of diesel into each cylinder. The onboard computer makes sure the fuel is injected at the optimum moment.

"This ensures lower emissions, makes the engine extremely responsive, and allows better fuel economy," HARI said.

The company also noted the level of refinement achieved in a diesel engine by the Hyundai CRDi.

"Although there is no mistaking the signature diesel engine noise when you start the car, once it is running, it is virtually indistinguishable from a gasoline-powered one in terms of driving and power delivery characteristics," it said.

The new CRDi engine in the Hyundai Starex produces 145ps and is capable of very fast acceleration with high torque even at low rpm. HARI added that the engine can even reach a top speed of 180 kph. Fuel efficiency is rated at "15% better than turbo intercooler diesel engines."

i like the CRDI of the Hyundai for power and torque,,, especially that there are glitches plauging the d4d of Toyota (refer to d4d woes thread), it may be newer but its not suited to our place.

[dlim]

for me, the hyundai CRDI is much better than the d4d.. because so far, no hyundai CRDI users had any problems with its commonrail, while the toyota innova's has alrrady very bad feedbacks about their D4D

[tebs]

ako, i'd go with starex. nothing about the engine. i'd just like the schoolbus space inside. hehehe... big family kasi kami. that would really save fuel money on our part rather than having 2 vehicles to transport us.

korean vehicles have gradually increased their reliability within the past few years. it's just that the dirty diesel we have that's making problems for the crdi engines being sold here. answer to that problem is biodiesel and more frequent changes of fuel filter

Toyota D4d ka nalang at least alam mo pag 5k na ODO reading mo masisira nato joke

hehhe! cool ka lang sir, maaayos din yng innova mo!

feeling ko.. kng pde lang ibalik/isoli katulad ng grocery ginawa mo na!

peace po tayo!

Tama ka dre. Infact it was mentioned sa ibang site that Sorento 2.5CRDi got a new technology upgrade. They call it VGT which stands for variable geometry turbo which enhaces Sorento 2.5 engine power from 140hp to 170hp. Di pa yan introduced sa pinas or even sa europe but in korea, it's already available. It's still with collaboration with Bosch company which as I have mentioned before, same company that pioneered this CRD technology.I think even BMW uses some components from bosch company for their CRDi that's why maski dito sa pinas, alang problem ang CRD engines ng BMW even though sabi nga ng iba na di maganda quality ng diesel.

i just found out that hyundai already launched in the Philippines their VGT engine (1.5 DOHC CRDi Turbo Intercooler with Variable Geometry Turbocharger) in the new Hyundai Accent w/ Max Output (bhp/rpm) 114 / 4000 and Max Torque (Nm / rpm) 241 / 2000... quite pricey though for a Hyundai at 748k but definitely worth at the pumps at 20.40 km/ltr(manufacturer's data)... i say that this is quite a tempting ride during this time of skyrocketing fuel prices..

Epic how is your Innova D4D? did you ever experience the same problem as larshell?

[Ventoy]

This is just Bosh technology against JaPANIS Denso kaya sorry to all D4D owners < Sana pwede swap ng engine Fortuner to one use by Hyundai CRDI VGT. I'm a Pro Toyota kaso this D4D problem nakaka-inis. I think Toyota engines were not suitable for Diesels

[boy starex crdi]

just bought my 2006 starex last december, and honestly speaking, i am surprised by its performance (power, torque, low vibrations, fuel economy etc), and ease of driving. It is comparable to a 2 liter gasoline engine (minus the fuel consumption thing). I know this because I have a toyota camry. I made reservation for the Fortuner but backed out because of the negative review on the D4D engine, which is quite sensitive (daw) to the "dirty" diesel fuel that we have. So far, I do not have problems with my new car, and I was glad I bought this one, which is very spacious that my 3 kids can even play hide and seek..
