Abstract:
The increased pollution of the air by engine vehicles has led most highly industrialized countries to reduce the limits on the emission of pollutants by combustion engines [1]. In order to evaluate the various measures for the reduction of pollutants [2, 3, 4, 5, 6, 7, 8], exhaust gas analysis systems with ever increasing performance are required [9, 10, 11]. The Sampling and Inlet System (SIS) presented here can resolve up to 100 gas samples per second with regard to time and make available associated with crankshaft angles to within 2°. In conjunction with a fast mass analyzer, the contents of exhaust gas can be determined in real time and on-line or with the use of an exhaust gas collection device, analyzed off-line without loss of time resolution. The system thereby makes an essential contribution to the expansion of dynamic exhaust gas analysis.
