What is Coagulation and Combustion of Soot Particles in Diesel Engines about?

Coagulation and combustion of soot particles formed in a diesel engine have been studied on two direct-injection diesel engines. Coagulation was studied by collecting samples of soot in the engine exhaust with a thermal precipitator and examining them by electron and optical microscopy. A coagulation constant which can be used to predict with a fair degree of accuracy the diameter of soot coagulates in the engine exhaust was derived. Soot combustion was studied by generating soot in two cylinders of a four-cylinder engine and recycling it in another cylinder where the soot-containing exhaust gases were subjected to a temperature cycle by undergoing compression. A soot combustion constant was derivo:l which can be used to predict the rate of soot combustion under known oxygen partial pressure. . The results of soot coagulation and combustion studies were applied to calculate for a diesel engine the importance of the combustion of soot during the expansion part of the cycle which follows the main burning period during the cycle. ~j SOOT RELEAS~ 8~ 8-.
