Abstract

Experimental studies of pollutant formation by concentration measurements (total HC, CO, CO(2), NO(x), O(2) and soot) were performed using a timed fast gas sampling technique. The test engine was a 1.9 l DI diesel engine for passenger cars. The concentrations were measured as a function of crank angle. From the results of the measurements the combustion at part load and idle was derived. Zones of soot formation and oxidation as well as NO(x) formation in and around the fuel spray were identified.
