Method and apparatus for conditioning an automotive vehicle engine to regenerate a particle filter

摘要

The method involves triggering reheating of an engine when the engine is found in a low temperature range presenting an upper limit situated between fifty and eighty degree Celsius and corresponding to a mechanical risk of the engine in case of triggering of a particle filter regeneration in the range. The engine is reheated by applying additional load e.g. a heating unit (700), on an electric alternator (800) of the engine. The heating unit is placed in an air inlet of the engine and heats the air in upstream of a cylinder. An independent claim is also included for a diesel engine of a motor vehicle, comprising a particle filter and regeneration unit of the filter.
