ABSTRACT:
An internal combustion diesel engine having a piston sliding in a cylinder and forming a main combustion chamber between the piston and the cylinder head. The cylinder head also has a pre-combustion chamber which communicates by a connecting passage with the main combustion chamber, with a fuel injection nozzle and glow plug arranged to project into the pre-combustion chamber. In addition, a smaller auxiliary chamber is provided which communicates with the pre-combustion chamber by a nozzle shaped aperture, and supplies additional combustion air to the pre-combustion chamber to help effectuate complete combustion, even at high engine loads, of the air-fuel mixture.
