FORKAMMARE TILL DIESELMOTOR

摘要

An improved diesel engine wherein fuel is preheated and vaporized within the precombustion chamber during a substantial portion of the engine cycle in which the precombustion chamber is isolated from the cylinder by an isolation valve. Compressed air from the engine cylinder is admitted to the precombustion chamber near the end of the compression stroke by the timed opening of the isolation valve. The precombustion chamber is shaped to enhance mixing of the compressed air with the preheated and vaporized fuel.
