摘要： An internal combustion engine torque estimation device that accurately estimates the torque of an internal combustion engine without being affected by engine speed changes. A reference signal, which is output at predetermined rotation angle intervals of a crankshaft for the engine, is acquired. In accordance with the reference signal, the amount of change in the rotation speed of the crankshaft is acquired as a rotational fluctuation. A filtering process is performed on the rotational fluctuation in synchronism with reference signal output timing to extract a frequency component synchronized with a combustion cycle of the engine. The torque of the engine is estimated in accordance with the extracted frequency component.

摘要： It is an object of the invention to enhance the possibility of realizing a required torque in a supercharging region where scavenging occurs in a control apparatus for a supercharged engine. In order to achieve this object, the control apparatus for the supercharged engine according to the invention determines an operation amount of an intake valve driving device from a target in-cylinder air amount that is calculated from a required torque, and determines an operation amount of a throttle from a target intake valve passing air amount that is obtained by adding an amount of air blowing through an interior of a cylinder to the target in-cylinder air amount.

摘要： This internal combustion engine is provided with a variable compression ratio mechanism capable of changing a mechanical compression ratio by changing the volume of the combustion chamber at the top dead center. The pressure and temperature of remaining combusted gas within the combustion chamber at the time when the exhaust valve is closed in the intake stroke is measured or estimated, the pressure and temperature of intake air supplied into the combustion chamber after the exhaust valve is closed in the intake stroke is measured or estimated, and based on the assumption that the pressure and temperature of the remaining combusted gas which saturates the volume of the combustion chamber at the time when the exhaust valve is closed in the air intake stroke become, when the intake air is supplied to the combustion chamber, equal to the pressure and temperature of the intake air, the volume of the remaining combusted gas after the change is calculated.

摘要： An object of this invention is to appropriately control the valve timing (VT) even in a case where a plurality of local maximum points or local minimum points exist on a characteristic line representing a relation between the VT and an air amount. An engine 10 includes VVTs 42 and 44 and the like. When a predetermined operation condition that a plurality of local maximum points exist on a load characteristic line representing a relation between the VT of an intake valve 32 and a load KL is established, an ECU 60 first calculates the VT corresponding to a maximum value KLmax of the load KL as a maximum air amount VT (VTmax). Subsequently, if the maximum value KLmax of the load is less than a target KL, the ECU 60 changes the VT towards VTmax. Thus, the direction in which the VT is changed is determined based on VTmax that is calculated irrespective of a change tendency (slope) of the characteristic line or the like at the current time. Therefore, even when a plurality of local maximum points exist on a characteristic line of an air amount index, it is possible to prevent the VT from being guided by the slope of a characteristic line or the like and latching onto a local maximum point that is not the optimal point.

摘要： Disclosed is a control device, which controls an air-fuel ratio sensor that is mounted in an exhaust path of an internal-combustion engine. The air-fuel ratio sensor is capable of pumping oxygen in a gas. Normally (time t0-t1, time t3 or later), a positive voltage Vp1 is applied to a sensor element (FIG. 7A), and the air-fuel ratio is calculated (FIG. 7C) in accordance with a sensor current (FIG. 7B). A heater is driven after internal-combustion engine startup to heat the sensor element. In a process in which the sensor element temperature rises, a negative voltage Vm, which is oriented in a direction different from that of the positive voltage Vp1, is applied to the sensor element.
