Experimental studies of pollutant formation by concentration measurements (total HC, CO, CO(2), NO(x), O(2) and soot) are performed using a timed fast gas sampling technique. The test engine is a 1.9 litre DI diesel engine for passenger cars. The concentrations are measured as a function of crank angle. The influence of engine operating parameters such as injection timing, injection rate and load on pollutant formation during diesel combustion is evaluated from the measurements. The results demonstrate that the fast gas sampling technique is well suited to the study of in-cylinder processes of internal combustion engines.
