Japan Clean Air Program (JCAP) - Activities of Combustion Analysis Working Group 2000-01-1974
The objective of the Combustion Analysis Working Group (WG) in JCAP is prescribed to analyze tail gas emission data obtained by the JCAP Diesel and Gasoline WGs, and to technically explain the origin of the difference in emission levels in terms of the engine, after-treatment, and fuel technologies applied in the measurements. Toward this end, the group firstly constructed the methodology necessary for providing the final outputs, and is carrying out systematical studies such as single-cylinder diesel engine experiments, contractual basis studies on diesel combustion mechanisms. Surveys on the mechanism and performance of after-treatments and the fuel effects on them are also being carried out. This report presents an overview of the methodologies, plans, and some results of the studies.
