Turbocharging Engines for Racing and Passenger Cars

The principle of exhaust gas turbocharging is known for more than 70 years. Only since a few years turbocharging is applied successfully to gasoline engines respectively to engines for passenger cars.

Mainly a poor throttle response and an unsatisfactory acceleration characteristic prevented turbocharging from general use.

The paper deals with the application of turbocharging for racing and passenger car engines. It is reported on the problems, improvements, and Porsche's experiences.

The future chances of turbocharging with regard to exhaust emissions and fuel economy are discussed.
