Hey guys, I'm glad you tuned in. It’s Tech Tuesday time with Benny!
Hi! I am happy he’s with me today. It's always fun to talk with him about technical highlights and how he experiences them in the car. Today we want to take a closer look at the technical changes in the Golf R 20 Years. That's what we promised you when we were in Sweden for the Tech Tuesday Special. We linked the video for you. Feel free to take a look. It came out really good! Definitely! Today we take you on a journey through the engine to talk you through the changes of the Golf R 20 years. To show you the technical highlights in detail, Sonja quickly removed the engine from our test vehicle.
Here we have again our well-known power unit, the EA888 in the 4th generation, as already in the Golf R with the DQ381 dual-clutch gearbox, which worked very well. And here we really made some further optimisation measures. Both in the inlet side and in the exhaust side. You have to imagine that the intake air arrives here and is compressed by the turbocharger. It then goes back over the intercooler and comes to the throttle flap. But we've also changed a bit on the engine itself. We can degenerate the internal engine sizes a little better and have been able to refine the application. We were able to add another 10 KW with this. So that we now have 333 PS.
Yes, 333 PS in the special edition. We get these because of the optimisation measures. Let's start at the inlet side. The throttle flap is located on the inlet side. Exactly here. And that controls how much air gets into the combustion chamber. So when you press on the gas, the throttle opens and when you step off the gas, it normally closes. This has the effect, when the throttle flap is closed, that the air that comes as Benny described earlier builds up in front of the closed throttle valve. Between this point and the combustion chamber, or the intake valves, a vacuum is being created, because the engine still draws in a little air.
And when you step on the gas again and the throttle valve opens, this area must first be filled with air until air is available for combustion. In the Golf R 20 Years, we changed it so that the throttle always remains fully open. This means that the air no longer accumulates in front of the throttle valve, but directly at the intake valves and is thus directly available for combustion as soon as you step on the gas.
