ABSTRACT:
An internal combustion engine provided with a precombustion chamber which utilizes a stratified charge type combustion process and is of a spark ignition type. This engine includes a main combustion chamber confined between the head of a piston, which is reciprocably fitted in a cylinder and one end wall of said cylinder a precombustion chamber defined in the head of said cylinder above said main combustion chamber and provided with an ignition plug and a fuel injection nozzle, a transer passage communicating said main combustion chamber with said precombustion chamber and an air intake port communicated through an air intake valve with said main combustion chamber. This precombustion chamber has an oval-shape in every section taken along a longitudinal axis thereof and incorporates many considerations such as the direction and cross sectional area of the transfer passage and the volume of the precombustion chamber as well as the direction of the fuel injection nozzle, thereby reducing the amount of NOx contained in exhaust gases from the engine.
