A start control system for an internal combustion engine which is capable of automatically restarting the engine while ensuring excellent startability and fuel economy of the engine, and permits reduction of the size of the system, to reduce the weight and manufacturing costs of the system. An electric motor drives an oil pump. An accumulator accumulates oil pressure delivered from the oil lamp. A hydraulic motor is connected to the accumulator via oil passage and driven by the oil pressure accumulated in the accumulator, for starting the engine. An electromagnetic valve is arranged across the oil passage, for controlling supply of oil pressure to the hydraulic motor. An ECU controls operation of the oil pressure supply control valve to thereby cause the hydraulic motor to start the engine.

1. A start control system for an internal combustion engine, comprising:an electric motor; an oil pump driven by said electric motor; an accumulator for accumulating oil pressure delivered from said oil pump; an oil passage through which said oil pressure is transmitted; a hydraulic actuator connected to said accumulator via said oil passage and driven by said oil pressure accumulated in said accumulator, for starting said engine; an oil pressure supply control valve arranged across said oil passage, for controlling supply of said oil pressure to said hydraulic actuator; control means for controlling operation of said oil pressure supply control valve to thereby cause said hydraulic actuator to start said engine; and misfire-detecting means for detecting a misfire of said engine, wherein said control means controls said operation of said oil pressure supply control valve such that said supply of said oil pressure to said hydraulic actuator is stopped, depending on an output from said misfire-detecting means.
