  • Method and apparatus for forming and burning a fuel-air-mixture in an air-compressing piston internal combustion engine
    Patent number: 3981286
    Abstract: A method for forming and burning a fuel-air-mixture in an air compressing piston type internal type combustion engine. At least a portion of the air compressed in the combustion space of the working cylinder is tapped off. The tapped off portion is passed into a chamber which is in communication with the combustion space. A measured amount of fuel is injected through an injection nozzle into a fraction of the portion of air during its recirculation into the combustion space. The fraction of air and the injected quantity of fuel are together accelerated towards the combustion space conveying the thus formed mixture into the air present in the combustion space during combustion. The quantity of fuel injected is adjusted and determines the amount of the air fraction. An apparatus for practicing the aforegoing method is also disclosed.
