摘要: During a shut-down period of an engine based on an idle stop control, a computer estimates a power stroke cylinder and a compression stroke cylinder when the engine is stopped. A fuel is injected into the power stroke cylinder and the compression stroke cylinder in an intake stroke just before the engine is stopped. An air-fuel mixture is hold in each cylinder with the engine stopped. When an auto start is required while the engine is stopped, a spark ignition is performed in the power stroke cylinder to start cranking of the engine by combustion energy. At nest ignition timing, a spark ignition is performed in the compression stroke cylinder to start the engine without an aid of a starter.

摘要: The present invention has an object to obtain an accurate amount of intake air at the time of an operation of an EGR mechanism in a control system of an internal combustion engine which is provided with a first fuel injection valve for injecting fuel into a cylinder, a second fuel injection valve for injecting fuel into an intake port, and the EGR mechanism. In order to achieve this object, the present invention resides in a control system of an internal combustion engine which is provided with a first fuel injection valve that injects fuel into a cylinder of the internal combustion engine, a second fuel injection valve that injects fuel into an intake port of the internal combustion engine, an EGR passage that introduces an EGR gas from an exhaust passage of the internal combustion engine to an intake passage thereof, an EGR valve that is arranged in the EGR passage, and an obtaining means that obtains an amount of intake air in the internal combustion engine, wherein when the EGR valve is open, a determination is made based on a value of a cylinder injection ratio, as to whether the amount of intake air is in an increasing tendency or in a decreasing tendency with respect to a change in the cylinder injection ratio, and a value of the amount of intake air thus obtained is corrected according to a result of the determination.
