ABSTRACT:
The present invention provides a swirl-injection type eight-stroke engine capable of constantly varying the injection-direction of the high-density-air from the slave cylinder, thereby effectively circulating the high-density-air around the master cylinder wall and master cylinder head during the injection process to speed up the mixing of the high-density-air and the hot combustion medium in the master cylinder, furthermore the hot spots in the master cylinder head and the master cylinder wall are eliminated with the two-direction swirling effect during the cold-expansion process.
