METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE AND A CONTROL AND REGULATION DEVICE

摘要

An internal combustion engine (30) with a supercharger device (50, 52) for increasing the charging pressure in an air inlet system (33) has a number of cylinders (32). Each cylinder (32) has at least one exhaust valve (36) which is connected to the exhaust system (40) and at least one inlet valve (34), which is connected to the air inlet system (33). Scavenging is carried out with a valve overlap between the inlet valve (34) and the exhaust valve (36). For controlling the operation of the internal combustion engine the system monitors whether the scavenging was successful.
