SOURCES OF HYDROCARBON EMISSIONS FROM DIRECT INJECTION DIESEL ENGINES

Some results of a systematic study on sources of unburned hydrocarbons from direct injection diesel engines are presented. The following possible sources are considered and investigated experimentally and/or analytically: local over-mixing, local under-mixing, bulk quenching, cyclic misfire, cyclic variation, and wall effects. The significance of each source under a variety of operating conditions including simulated deceleration, light loads, high loads, and simulated acceleration are discussed.
