ABSTRACT:
A gasoline engine of four-cycle spark ignition type comprises a piston-cylinder assembly having a piston including a partition and a combustion chamber separated into two compartments by the partition in the forward portion of the piston reciprocation, and an ignition plug set in one of the compartments in which the first combustion occurs. In this case, the ignition timing is determined in a period in which the ignited flames are retained by the partition so as not to contact the mixture in the other compartments, and the flames in the first combustion compartment are in contact with the combustible mixture in the next compartment when the compartments communicate with each other by releasing the separation of the chamber in the back portion of the piston reciprocation stroke.
