ABSTRACT:
An internal combustion engine of the type in which the combustion space is divided into a main combustion chamber and an auxiliary combustion chamber connected to each other by a communication passage, and an ignition plug and a fuel injection nozzle are provided for the auxiliary combustion chamber so that the flame produced by the ignition and combustion of a arch fuel-air mixture in the auxiliary combustion chamber spreads into the main combustion chamber to cause effective secondary combustion in the main combustion chamber, and the upper surface of a crown of the piston has a conical configuration of which the apex is located to be brought to a position adjacent to the center of the opening of the communication passage opened to the main combustion chamber when the piston reaches the upper dead point in the compression stroke thereof, and the crown has a bank formed on the peripheral edge of the crown.
