摘要： A control unit according to the present invention performs an automatic stop control in which an injection of fuel from a fuel injection valve is stopped to stop a rotation of an engine when an automatic stop condition is satisfied. Furthermore, the control unit performs a first injection, in which fuel is injected from the fuel injection valve of a cylinder in an expansion stroke, and an ignition operation for igniting the fuel injected by the first injection, when a restart demand occurs after an initiation of the automatic stop control. In addition, the control unit performs a second injection, in which fuel is injected from the fuel injection valve of a cylinder in a compression stroke, and an ignition operation for igniting the fuel injected by the second injection. Then, the control unit performs a third injection, in which fuel is injected from the fuel injection valve of a cylinder in a compression stroke, when it judges that a start-up failure for which a crank angle of the cylinder which is in the compression stroke after the second injection cannot get over the compression top dead center occurs or will occur.

摘要： The invention relates to a control device of a multi-cylinder internal combustion engine. The control device starts executing an ignition engine start control to restart the engine operation when a predetermined engine restart request is generated, a last signal output from a crank angel sensor corresponds to the compression TDC and a signal is output from the sensor before a time elapsing from the output of the last signal reaches a predetermined time. The control device starts executing a starter engine start control when the engine restart request is generated, the last signal output from the sensor corresponds to the compression TDC and no signal is output from the sensor before a time elapsing from the output of the last signal reaches the predetermined time. The control device sets the predetermined time on the basis of a last engine speed acquired on the basis of the last signal and a signal output from the sensor immediately before the last signal is output such that the predetermined time set when the last engine speed corresponds to a first engine speed, is longer than the predetermined time set when the last engine speed corresponds to a second engine speed larger than the first engine speed.

摘要： A control device according to the present invention performs an automatic stop control in which an injection of fuel from a fuel injection valve is stopped and a rotation of an engine is stopped when an automatic stop condition is satisfied. Furthermore, the control device controls an injection operation of fuel and an ignition operation to the fuel in consideration of compression when the fuel is actually ignited in an expansion stroke cylinder, when a re-start demand occurs after an initiation of the automatic stop control and the engine is to be re-started by an ignition start-up. Specifically, the control device predicts a crank angle at an actual ignition time point in a case where processing for performing the ignition start-up at the present time whenever a predetermined time period has passed. Then, the control device initiates the ignition start-up when the crank angle falls within a predetermined range in which a sufficient compression can be attained. Thereby, the engine is more certainly re-started by the ignition start-up.

摘要： The control device executes a first control for controlling a throttle valve opening degree to a first opening degree when a particular condition is satisfied. The particular condition is a condition that it is predicted upon a satisfaction of an engine stop condition that a level of one of noise and vibration generated in an interior of a vehicle from a source other than an engine is equal to or larger than a predetermined level when an engine rotation stops. The control device executes a second control for controlling the throttle valve opening degree to a second opening degree larger than the first opening degree without executing the first control when the particular condition is not satisfied upon the satisfaction of the engine stop condition.
