  • Method for reducing the particle emission of an internal combustion engine and engine controller
    Patent number: 9422885
    Abstract: The present invention relates to a method for reducing the particle emissions of an internal combustion engine over its service life. The number of cylinders of the internal combustion engine in which post-injection is carried out is incrementally increased during the service life of the internal combustion engine. The increase in the number of cylinders receiving a post-injection may depend upon at least one parameter, which may be a running time, a distance performance, a particle concentration in exhaust gas, a load profile, or other parameter. The individual cylinders receiving post-injection may be changed to distribute wear.
