SUPERCHARGED INTERNAL-COMBUSTION ENGINE WITH A FILTER FOR EXHAUST GAS PARTICLES

摘要

In order to limnit the exhaust particulate emission when supercharging a pressure wave machine-supercharged internal combustion engine, an exhaust particulates filter is arranged in the high-pressure part of the exhaust gas system ahead of the pressure wave machine. By increasing the supply of fuel to the engine itself and/or briefly closing a charge air flap valve a recirculation flap valve and/or brief opening of a exhaust gas by-pass valve, the exhaust gas attains the combustion temperature of soot components deposited on the surface of the filter. These soot components are burned off, and the filter is automatically regenerated.
