Abstract
An auxiliary chamber () having a spark plug () and an auxiliary fuel injector is formed at the central part of the top surface of the main combustion chamber (). When making an air-fuel mixture in the auxiliary chamber () burn by the spark plug (), an air-fuel mixture in the main combustion chamber () is made to burn by jet flames ejected from the communicating holes (). The injection ports of the auxiliary fuel injector () are oriented toward a tumble flow inflow peripheral region (R) which is located on the peripheral part of the end portion of the auxiliary chamber () at a place located on a side where the tumble flow W flows in from the communicating holes (). When the tumble flow (W) is made to be generated in the main combustion chamber () by the tumble flow control valve (), auxiliary fuel (QF) is injected from the auxiliary fuel injector () toward the tumble flow inflow peripheral region (R) of the auxiliary chamber ().
