摘要： An internal combustion engine inner-cylinder pressure estimation apparatus includes a detection unit that detects an operation condition of an internal combustion engine, a calculation unit that calculates an ignition delay that is an interval from an ignition timing to a starting timing of heat generation by combustion, based on an operation condition detected by the detection unit, and a combustion velocity calculation unit that calculates a combustion velocity, based on the operation condition. There is simulated a phenomenon that after an ignition delay period following an ignition timing has elapsed, a flame generated at the gap portion of an ignition plug expands up to the inner-cylinder wall surface at the combustion velocity and in the shape of an ellipsoid whose center is the gap portion of the ignition plug.

摘要： Provided are a control device and a control method for an internal combustion engine, which enable a throttle-valve upstream pressure through simple calculation processing without being affected by a state of an opening degree of a wastegate valve (WGV). When a wastegate (WG) command value to a WGV driving section (212) for driving a WGV (33a) provided in a bypass passage (33) which bypasses a turbocharger (32) is to control supercharging to be weakened to the lowest level, the throttle-valve upstream pressure is estimated from an exhaust-gas amount. Otherwise, a value obtained by adding a preset value to an intake-manifold pressure is used as a throttle-valve upstream pressure estimate value. As a result, the throttle-valve upstream pressure is estimated with high accuracy by an inexpensive configuration without mounting a throttle-valve upstream pressure sensor, and then engine control is performed.

摘要： A target injector valve opening period is calculated based on a target fuel injection amount, and an injector (2) is controlled by a current supply control unit (51) in accordance with an injector drive period acquired based on the target injector valve opening period. An actual valve closing delay period is calculated based on a drive waveform of the injector (2) at this time, and a difference between an actual valve closing delay period and a valve closing delay period calculated from a target injector valve opening period is learned. Then, the injector drive period is corrected by feedback control using a result of this learning.
