STRATEGY FOR QUENCHING INCIPIENT COMBUSTION OF RESIDUAL HOMOGENEOUS CHARGES DURING COMPRESSION STROKES IN A DIESEL ENGINE
摘要
During regeneration of a DPF (22), cylinders of a diesel engine (12) are fueled by main injections and post-injections. This creates exhaust having sufficiently high temperature and suitable constituent content to cause particulates trapped in the DPF to burn off. However, residual unburnt fuel will create an air-fuel mixture that is sufficiently homogeneous to begin combusting during a subsequent compression stroke. The invention quenches incipient combustion of the mixture during the compression stroke by injecting fuel into the respective cylinder before the next main injection of fuel.
