An interior combustion engine is basically a large air pump that powers itself using fuel. As the air is trapped, sufficient fuel has to be provided to create power to maintain the engine's procedure while having a valuable amount left over to propel the automobile when required.

The temperature of the air also plays a role in combustion top quality in much the very same way as the differing atmospheric stress.
