<p>The present invention relates to a device designed to regulate automatically the compression ratio of the mixture taken in at the various levels of r.p.m. of an explosion engine of an aspirated type to achieve a balanced matching of its thermal and mechanical efficiency. The above is obtained, according to the invention, by providing a regulator comprising means actuated by the pressure of the engine oil, which are designed, to vary automatically, as a function of the engine r.p.m. and starting from the regime of the maximum torque onwards, the effective stroke of the piston in the proximity of the top dead centre.</p> |
