Abstract
A Stratified Charge Engine where the main combustion chamber is made into one part of the cylinder head is described. The main combustion chamber in this engine is smaller than in Pre-Mixture Combustion Engines. Other main features of this engines are direct and simultaneous air/fuel injection, installation of a squish area and prevention of combustion in the end-gas zone. The thermal load and the weight of the piston in this engine are lower than in normal Stratified Charge Engines with fuel jet impingement. The fuel jet is kept inside the main combustion chamber, resulting in an higher anti-knocking quality of this engine as compared to Pre-Mixture Combustion Engines.
