Diesel Engines Combustion and Emissions

  • N. A. Henein


This chapter analyzes diesel combustion and emissions with emphasis on high-speed transportation engines. The contribution of these engines to air pollution in the USA is presented in Table I as the relative percentage of the emissions from other sources.(1) It may be seen that the two highest percentage emissions from the diesel engine are particulates and nitrogen oxides. Its other emissions that are not shown in Table I are the oxygenated hydrocarbons (including aldehydes), the odor constituents, and noise. The diesel emissions most offensive to the public are the exhaust odor and the visible smoke particulates.
