Operating principle
The new 90-kW TSI
Effective actions taken to reduce fuel consumption and improve driving dynamics are direct gasoline injection, engine charging and reduction of engine displacement. Volkswagen is taking precisely this approach in its TSI engines: Reducing engine displacement, and thereby lowering friction and throttle adjustment losses, results in lower specific fuel consumption and a higher level of efficiency. Depending on the performance class, this is done either by a combination of turbocharger and supercharger, or simply with a specially developed turbocharger as on the new TSI.
The TSI, which is 90 kW strong over a wide range from 5,000 to 6,400 rpm and offers a very high specific torque of 144 Newton-meter per liter, delivers exceptionally agile response even from very low engine speeds without the addition of a supercharger. There is no turbo hole here. When it comes to forming the charge mixture, Volkswagen implements, and this is the case in its TDI engines as well as the TSI, a combination of engine charging and direct injection. Here too it is clearly evident that gasoline direct injection and engine charging complement one another ideally and together enable an unprecedented increase in efficiency.
