Patent ID: 7322342

Claim:
A control device of an in-cylinder direct-injection internal combustion engine applied to an in-cylinder direct-injection internal combustion engine, in which fuel is directly injected into a combustion chamber of each cylinder from a fuel injection valve and an air-fuel mixture formed by fuel injection is ignited by a spark plug and burnt, and controlling ignition cut-off for suspending ignition by said spark plug when said internal combustion engine is started at an extremely low temperature, comprising: an injection amount calculating unit calculating a requested injection amount of fuel necessary during ignition cut-off based on a temperature of engine coolant, when said internal combustion engine is started at the extremely low temperature; an injection timing setting unit setting injection start timing and injection end timing between which wetting of said spark plug by fuel is less likely; an ignition cut-off times calculating unit calculating number of times of ignition cut-off based on the set injection start timing and injection end timing and a calculated value of said requested injection amount; and a start control unit carrying out ignition cut-off at the time of start at the extremely low temperature based on a calculated value of the number of times of ignition cut-off.
