Abstract
The invention relates to a method for improving the initial conditions for starting a direct injection, spark-ignition internal combustion engine. Measures, such as adjusting the throttle valve, a varying inlet and exhaust valve timings, operating a secondary-air pump, ensures that the internal combustion engine, when running down, scavenges exhaust gases from the cylinder by providing fresh air into the. Furthermore, measures are undertaken for the braking and/or active rotation of the internal combustion engine so that it is a suitable position for renewed starting, the restarting being accomplished without the aid of a starter motor.
