Method and device for reducing the load of exhaust gas components of internal combustion engines

摘要

The method involves setting a fuel-air ratio close to lambda 1 or higher (weaker) for high anticipated exhaust gas temp. using the fuel and air delivery system (64) and blowing cool air into the exhaust gas system (24) close to the combustion chambers of the internal combustion engine (10). The cool air is delivered by a pump (58) mounted on the engine An Independent claim is also included for an arrangement for implementing the method.
