Fuel injection system for combustion engine regulates additional fuel (e.g. LPG) fed to combustion chamber with lambda probe in exhaust flow upstream of catalyser and associated control electronics

摘要

The system has a high pressure pump for transporting preferably self-ignition fuel into a dual fuel nozzle (30) and a transport device for transporting an additional fuel, preferably liquid petroleum gas, via an additional fuel line to the dual fuel nozzle. The additional fuel quantity fed into the combustion chamber can be regulated via a lambda probe (75) in the exhaust flow (85) upstream of the catalyser and associated control electronics (80).
