Petrol Direct Injection

Petrol Direct Injection

With petrol direct injection, the fuel is injected directly into the combustion chamber at a pressure of over 100 bar. Compared with conventional injection into the inlet manifold, this process is considerably more precise and is not dependent on the opening times of the valves.

A special combustion chamber geometry ensures an optimum mix of the fuel and air. Volkswagen engines with petrol direct injection are extremely efficient. With an appropriate driving style, the fuel saving compared with engines of the same power output with conventional injection technology can be as much as 15 percent. Petrol direct injection serves as the basis for innovative TSI technology.
