System for assisting the regeneration of a particle filter comprised in the exhaust pipe of a diesel vehicle engine

摘要

An engine data collection and analyzing unit (18) determines the phasing and quantity of multiple fuel injections to be made for particle filter regeneration and also the current motoring mode. A history of motoring modes is kept (19) and the probability that a more favorable mode than the current mode will occur is calculated and used to either initiate or defer the regenerative process
