COMBUSTION CHAMBER FOR SUPERCHARGED INTERNAL COMBUSTION ENGINE

摘要

An auxiliary combustion chamber for use with a supercharged Diesel engine comprises a fuel injection and spraying device adapted to operate with delivery rates which are variable within a broad range. The device has a fuel injection port which opens into the chamber. The size of the port is such that the fuel is mechanically atomized when injected at the maximum rate. Air passage nozzles open into the combustion chamber at a location close to the port and deliver air jets at a speed and at a delivery rate sufficient for it to atomize the fuel effectively at minimum fuel delivery rate.
