Abstract
Measurements of particle concentrations in one cylinder of a 1982 5. 7 liter GM V-8 diesel engine have been made using a unique total cylinder sampling system. The first part of the paper is devoted to an examination of the performance of the sampling system. The role of blowoff and nucleation in the formation of sample artifacts is discussed. The remainder of the paper is devoted to the results of a study of the formation and removal of carbon particles during diesel engine combustion. Several operating conditions have been examined. The influence of both injection timing and load on particle formation and removal has been investigated. The concentrations of volatile and non-volatile particulate matter have been measured as a function of crankangle position. Particle formation begins 1-5 CAD after the start of combustion.
