TDI with Common Rail: Explained & Benefits

Hello,

I stumbled upon this information randomly on the Wendland website.
It also includes a list of all the modifications made to transform the standard engine into a high-performance TDI racing engine with 200 horsepower.

Hi Gustav,

... is that the base engine is specified as a 1.9-liter with common rail (CR) technology.

"By 'base,' I mean a standard engine, but currently, there isn't a 1.9L VAG CR-TDI available... or is Wendland modifying a VAG in-house CR racing TDI to produce 200 hp / 400 Nm?"

Or is the information on the website simply nonsense, at least regarding the base engine?

You are so funny!
I'm posting this here because I randomly found it on the Wendland website, and I thought that some people might be interested in it. Perhaps it could even lead to a new discussion .

I was wondering the same thing.

Despite everything, best regards .

I'm surprised that Wendland made the conversion to 200 horsepower seem so complicated, or is it just a bunch of nonsense?

One would need to know what type of base motor was used.

If you've already used a VP-TDI engine, this conversion shouldn't be too difficult, as long as you can secure the fuel pump and injectors properly.
But the effort required is far too much!

Take a PD engine with 130 hp TDI power, replace the VNT17 turbocharger with a VNT20, modify the intake system, increase the intercooler threefold in size, install an exhaust system designed to reduce back pressure and include a metal catalytic converter. Depending on needs, you can also add a tropical-type water cooler and an oil cooler.

After software programming adjustments, achieving around 200 horsepower and over 400 Nm of torque is possible without compromising the engine's durability.

Manuel.

To get back to the topic.

VW has already publicly acknowledged in industry publications that they are developing a common-rail system because the PD technology is reaching its limits, especially with regard to exhaust emissions and fuel consumption. Particularly when combined with particulate filters or NOx storage catalysts, a common-rail system is essential because it provides absolute freedom over injection timing (keyword: post-injection).

@ Gremlin

Unfortunately, I have to disagree with you. VW is continuing to use the PD (Pump Denoise) technology. If you examine the operating principle of the PD units closely, you will realize that they achieve the most homogeneous injection among all injector elements.

Why would VW develop a new 2.0L PD-TDI engine when they intended to switch to common rail technology? Audi is gradually transitioning to common rail in order to differentiate itself from VW. They started with the 3.3L V8 TDI, and the new 4.0L TDI will also be a common rail engine.

Have you ever seen a diesel engine that meets Euro 4 standards without using common rail (PD) technology?

Manuel.

Hello!


Volkswagen and Siemens plan to build a joint plant. The purpose is to introduce piezo common rail injection systems at Volkswagen.

That doesn't mean that PDs will simply disappear overnight.

Certainly, the method using piezoelectric crystals offers enormous possibilities. It allows for multiple pre- and post-injections to reduce emissions.

Certainly! Please provide the German text you would like me to translate into English. I will only provide the translation.

VW has actually been using common rail diesel engines in its vans for quite some time.
Perhaps the 2.0 PD with 16V is just a transitional engine, used to avoid falling behind in competition, because common rail engines are not yet sufficiently advanced at Volkswagen?
Volkswagen has internally admitted to having been complacent in the development of diesel technology. In fact, I once read a report suggesting that Mr. Piech accused the head of the development department or someone similar of this.

Hi, the 2.8L.

see: http://www.vw-nutzfahrzeuge.de/index.html?technik/lt_28tdi_motor.html

@ Manuel Thomas - it seems like you are ahead of your time; for me, it's currently 21:05 .

Which LT engine is a common rail engine?

Regards,

Manuel.

@manuel

I will put the announcement online sometime during the course of Monday .

The 2.8L engine in the LT is a common rail engine. The engine code is AUH.
VW is also continuing to work on common-rail engines. Indeed, it appears that pump-injector technology is reaching its limits in terms of development potential.
It seems that this has been assessed differently up until now.

Best regards, Lanz.

Check out Erwin's page; there's an information sheet about the VW CR diesel engine!

The engine from the LT is a purchased component from a Brazilian manufacturer. Volkswagen itself does not plan to use any common-rail (CR) engines.
For the LT, a large-volume diesel engine was needed as quickly as possible, and therefore the 2.8L CR engine was installed (it was not desired to purchase it from DC... ).
Audi is currently developing Common Rail (CR) engines and they are likely to be used in the next generation of six-cylinder models. The Pumpe-Düse (PD) technology is currently only feasible up to five cylinders, which is why the V10 PD TDI is essentially a twin five-cylinder engine.

The development of pneumatic technology is far from over. It would be very detrimental because it is widely used in the truck sector, and the current state of the art (see the DC Actros) demonstrates this.
Currently, the PD Tewchnik is the only one capable of meeting the 2004 emission standards without additional particulate filters (which Volkswagen absolutely opposes).

Common rail technology has been around for a while, even in trucks. At Volkswagen, engineers were still working on the TDI engine with a unit injector pump.
