Measurements of carbon oxidation rates in a diesel engine

Research output: Contribution to journalArticlepeer-review


Formation and oxidation of particle generated within cylinder of a passenger-car-type indirect-injection diesel engine have been studied. The history of both the particle mass and surface concentration were determined within the combustion chamber at different crankangles during expansion stroke using a system which allows the cylinder contents to be rapidly expelled, diluted, and collected in a sampling bag for subsequent analysis with an electrical aerosol analyzer. A stochastic model developed by MIT was used to simulate measured particle concentration profiles. The observed particle removal rates could be simulated using a kinetic expression given by K.B. Lee and J.M. Beer. However, this result was very sensitive to the assumed value of particle diameter used in the simulation model.
