Abstract
The invention concerns an internal combustion engine provided with a vacuum sensor for monitoring the level of partial vacuum in the engine's inlet manifold, in order to provide an indication of engine load. during changes in engine load, the level of partial vacuum presented to the vacuum transducer is modified from that obtaining in the inlet manifold in order to improve the accuracy of the output of the transducer during changes of engine load.
