  • Method for controlling a diesel engine with a common-rail injection system during regeneration of the particulate filter
    Patent number: 7140345
    Abstract: Method for controlling a diesel engine with a common-rail injection system and a particulate filter, comprising the steps of performing at least one main injection (PRE, MAIN, AFTER) of fuel into a cylinder of the engine, the fuel being intended to take part in combustion inside the cylinder, and performing a post-injection (POST) in order to inject a predefined total quantity of fuel (QPOST) inside the cylinder, the post-injection being separated from the main injection (PRE, MAIN, AFTER) by means of a time separation interval such that the fuel injected during post-injection does not take part in combustion. The method also comprises the step of dividing the post-injection (POST) into a plurality of separate post-injections (POST1, POST2, POST3).
    Type: Grant
