INTERNAL COMBUSTION ENGINES

An internal combustion engine is provided with vacuum pump (17) to remove burnt gases from the engine cylinders during an exhaust stroke. The vacuum applied by the pump (17) is sufficient to remove the gases during an exhaust stroke and also apply a force to lift the piston. A certain amount of torq...

Summary:An internal combustion engine is provided with vacuum pump (17) to remove burnt gases from the engine cylinders during an exhaust stroke. The vacuum applied by the pump (17) is sufficient to remove the gases during an exhaust stroke and also apply a force to lift the piston. A certain amount of torque is therefore generated during the exhaust strokes. It is a similar manner and to similar effect a compressor (18) is provided to force fuel into the cylinders during induction strokes and also create a certain amount of positive torque. L'invention concerne un moteur à combustion interne. Ce moteur est pourvu d'une pompe à vide (17) pour évacuer les gaz brûlés des cylindres du moteur pendant la course d'échappement. Le vide appliqué par la pompe (17) est suffisant pour évacuer les gaz pendant une course d'échappement et appliquer également une force pour soulever le piston. Une certaine quantité de couple est ainsi généré pendant les courses d'échappement. De la même manière, un compresseur (18) est prévu pour forcer le carburant dans les cylindres pendant les courses d'admission et créer ainsi une certaine quantité de couple positif.
