The new Volkswagen Passat has just been presented as a preview of what awaits us at the Geneva Motor Show in 2019. We've already explained to you what the changes of this sedan would be and we'll talk about it in the next days. One of the points I want to emphasize with this article is its new engines. In truth, none of them is a raging novelty, and had already been published in other cars … except for one of them. I'm talking about new 2.0 TDI Evo engine, the last letter to Volkswagen diesel. What do we know about this engine?
This propeller develops a final power of 150 hp. The engine belongs to the same EA288 family as the current engines of Volkswagen 2.0 TDI, but was subjected to a very thorough review of all its internal components. According to Stefan Gies – Product Manager of the new Volkswagen Passat – this engine shares the core of its architecture with the rest of the 2.0 TDI engines, but many of his pieces have been redesigned or renovated for more efficiency. In fact, they claim that it emits 10 g / km less CO2 as the existing 2.0 TDI 150 HP engine up to now.
Until the advent of electricity, this TDI Evo will be the spearhead of Volkswagen in terms of energy efficiency in internal combustion.
Some of the pieces that have changed are their pistons, now constructed of steel and longer stroke. The supercharging system has also been improved, as has the design of the intercooler. Reducing internal friction between engine parts was another priority for Volkswagen, which resulted in new crankshaft design and (possibly) new internal coatings. The engine cooling system has also been completely renewed in order to achieve a better cooling of the cylinder head. We do not know many more specific details of these engines.
The press release is brief and is limited to indicating that these engines are compatible with the Euro 6D-Temp and that its emission control system relies on the injection of AdBlue on the exhaust gases , in addition to the necessary particulate filter. Another important detail is that this EA288 Evo engine family will feature variable cylinder disconnection: This 2.0 TDI can operate with two cylinders in low load situations, reducing the car's fuel consumption. For some time, there had been talk of semi-hybrid engines, associated with a 48-volt electrical system.
They may have a refrigerated EGR and an integrated exhaust manifold in the cylinder head for better control of optimal operating temperatures.
In the case of the Volkswagen Passat, the 2.0 TDI Evo will not be a soft hybrid engine. Volkswagen claims that the return on investment needed to install a 48-volt electric system – in a car that is still around three years old on the market – is insufficient in this case. Whatever it is, the industry expects these engines to be micro-hybrids in the next generation of the Volkswagen Golf, without going further. As soon as we know more about this engine family, we'll let you know. For the moment, keep an eye on the information we previously posted on the EA288 Evo.
Just know … will it be from the latest Volkswagen diesel engine family? The mark has already set the expiry date of the internal combustion.
