SPARK-IGNITED INTERNAL COMBUSTION ENGINE AND METHOD OF CONTROLLING THE SAME

A spark-ignited internal combustion engine includes a variable compression ratio mechanism that changes a mechanical compression ratio and an actual compression ratio start timing-changing mechanism that changes a start timing at which actual compression starts. An actual compression ratio is change...

More Information
Summary:A spark-ignited internal combustion engine includes a variable compression ratio mechanism that changes a mechanical compression ratio and an actual compression ratio start timing-changing mechanism that changes a start timing at which actual compression starts. An actual compression ratio is changed according to the specific heat ratio of an intake gas that is supplied into a cylinder. L'invention concerne un moteur à combustion interne à allumage par étincelles comprenant un mécanisme à rapport de compression variable qui modifie un rapport de compression mécanique et un mécanisme de modification du temps de départ à rapport de compression réelle qui modifie un temps de départ auquel commence la compression réelle. Un rapport de compression réelle est modifié conformément au rapport thermique spécifique d'un gaz d'admission qui est envoyé dans un cylindre.
