ABSTRACT:
When analyzing exhaust gases from vehicle internal combustion engines according to the simplified method, where the inertia and the internal losses of the engine are used as braking factors and the engine, during a given period of time, is subjected to a series of short incidents of fuel supply increases above idling speed level, it is important to ensure that all play is eliminated in the transmission path between the monitoring unit determining the fuel increase incidents and the fuel supply means. The fuel supply increase incidents should furthermore be selected so with respect to resulting changes in effective mean pressure (PME) and speed (RPM), that the fuel supply means, during each incident, will be displaced in a positive direction only, until the engine returns to the idling speed level.
