ABSTRACT:
The composition of the combustible mixture supplied to an internal combustion engine is controlled in dependence on the fluctuations in cylinder pressure which are monitored by sensing the fluctuations in the rotation of the engine crankshaft. These fluctuations are measured by comparison with a signal which simulates an engine running uniformly at the basic engine r.p.m. The signal which characterizes the r.p.m. fluctuations is compared with a nominal or command value and the resulting signal is used to control the mixture composition so as to maintain the fluctuations within predetermined limits.
