Particle filter regenerating method for e.g. diesel type internal combustion engine, involves increasing temperature of exhaust gas at inlet of oxidation catalyst during idle phase of engine and regeneration of filter

摘要

The method involves injecting fuel e.g. diesel oil, into an exhaust line in upstream of an oxidation catalyst that is disposed in upstream of a particle filter. Temperature of the exhaust gas at an inlet of the catalyst is increased during an idle phase of an internal combustion engine and regeneration of the filter, where the temperature of the gas at the inlet is adjusted by modifying injection parameters of the engine. Temperature of an internal surface of an exhaust tube between an injection point of fuel and the inlet of the catalyst is adjusted to a high value of 360 degree Celsius. An independent claim is also included for a device for implementing a method of regenerating a particle filter comprising a temperature sensor.
