Ultra-low emission vehicle design for high performance engine

摘要

The present invention relates to an internal combustion engine having an exhaust port camshaft and an adjusting device for an ignition control device. In order to reduce the emission of harmful substances and to obtain an internal combustion engine which can also reach the limit value for the emission of harmful substances, it is proposed that the adjusting device for the exhaust camshaft in the partial load region is controlled such that the exhaust camshaft is delayed. At the same time, the purge control delays the purge time.
