Coagulation and combustion of soot particles in diesel engines

摘要: Coagulation and combustion of soot particles formed in a diesel engine have been studied on two direct-injection diesef engines. was by collecting samples the exhaust with thermal precipitator examining them electron optical microscopy. A coagulation constant which can be used to predict fair degree accuracy diameter coagulates derived. Soot generating cylinders four-cylinder recycling it another cylinder where soot-containing gases were subjected temperature cycle undergoing compression. derived rate under known oxygen partial pressure. The results studies applied calculate for importance during expansion part follows main burning period cycle.
