摘要： A control apparatus for an internal combustion engine is configured, during a slightly stratified-charge lean-burn operation, to: calculate a basic total fuel injection amount based on a required torque; calculate a compression stroke injection amount based on an ignition delay index value; calculate, as a basic main injection amount, a value obtained by subtracting a compression stroke injection amount from the basic total fuel injection amount; calculate, based on an output value of an in-cylinder pressure sensor, an actual specified combustion index value that represents a main combustion speed or a combustion fluctuation rate; calculate a main injection correction term based on a result of a comparison between a target specified combustion index value or a tolerable specified combustion index value, and the actual specified combustion index value; and calculate a main injection amount by adding the main injection correction term to the basic main injection amount.

摘要： An internal combustion engine is provided that executes fuel injection and ignition with respect to a cylinder that remains stopped in an expansion stroke, and that performs ignition startup that starts up the internal combustion engine by rotationally driving a crankshaft by pressure of combustion accompanying the fuel injection. A motor generator (MG) that can rotationally drive the crankshaft is provided. A required assist torque Ast_trq exerted by the MG at the time of ignition startup is determined based on a maximum value Cyl_prss of an in-cylinder pressure that is detected by an in-cylinder pressure sensor at the time of ignition startup. The MG is controlled at the time of ignition startup based on the required assist torque Ast_trq that is determined.

摘要： A controller for an internal combustion engine includes a crank angle detector and an ECU. The ECU is configured to: (a) calculate a mass fraction burned; (b) acquire the crank angle, which is detected by the crank angle detector when the mass fraction burned reaches a predetermined mass fraction burned, as a specified crank angle; and (c) control at least one of an amount of fuel injected, an amount of intake air, or ignition energy on the basis of a first difference. The first difference is a difference between a first parameter and a second parameter. The first parameter is a crank angle period from an ignition time to the specified crank angle or a correlation value of the crank angle period. The second parameter is a target value of the crank angle period or a target value of the correlation value.

摘要： A control device for an internal combustion engine is provided that can detect the adherence of deposits to a cylinder pressure sensor without subjecting the internal combustion engine to an impact or the like. A control device for an internal combustion engine equipped with a cylinder pressure sensor detects changes in the sensitivity of the cylinder pressure sensor. If the control device detects a decrease in the sensitivity of the cylinder pressure sensor after detecting an increase in the sensitivity of the cylinder pressure sensor, the control device determines that deposits are adhered to the cylinder pressure sensor.

摘要： This invention determines whether or not an internal combustion engine is not performing combustion. If the determined result is that the internal combustion engine is not performing combustion, a maximum in-cylinder pressure Pmax during motoring is identified by an in-cylinder pressure sensor, and a crank angle θPmax corresponding to the maximum in-cylinder pressure Pmax is detected by a crank angle sensor. Further, a reference crank angle θPmaxtgt corresponding to the engine speed and the engine load factor is identified, and θPmax is corrected so as to become θPmaxtgt. Furthermore, the relation between a signal of the crank angle sensor and a crank angle (measured value) corresponding to the signal is corrected so that a measured value of the crank angle corresponding to Pmax becomes the post-correction crank angle.
