Spark ignition internal combustion engine |
| abstract |
The actual compression ratio is determined according to the octane number. A variable compression ratio mechanism A capable of changing a mechanical compression ratio and a variable valve timing mechanism B capable of controlling a closing timing of an intake valve 7 are provided. The mechanical compression ratio is maintained at the maximum mechanical compression ratio on the engine low load operation side, and gradually decreases as the engine load increases on the engine high load operation side. The actual compression ratio is increased as the octane number of the fuel supplied into the combustion chamber 5 increases. [Selection] Figure 10 |
