For convenience' sake, a “crank angle at which dPVκ/dθ is a maximum while PVκ is increasing” is to mean a “crank angle at a combustion proportion of 50%” and be referred to also as “θCA50”. PVκ calculated for θCA50 is to be referred to also as “PVκCA50”. In addition, for convenience' sake, a difference between PVκ (which is zero in the embodiment as shown in FIGS. 3 and 4) and PVκCA50 at a start of combustion is also referred to as ΔPVκCA50.

摘要： To accurately specify an EGR rate from an output value of an in-cylinder pressure sensor, a specifying method of an EGR rate in an internal combustion engine of the present invention acquires an output value of an in-cylinder pressure sensor at an intake stroke to calculate comparison data related to an in-cylinder pressure at the intake stroke from the acquired sensor output value. An output value of the in-cylinder pressure sensor at an exhaust stroke of the same cycle is also acquired to calculate comparison data related to the in-cylinder pressure at the exhaust stroke from the acquired sensor output value. Two comparison data are compared to specify the EGR rate of an air-fuel mixture provided for combustion from a difference between the values.

摘要： A control device for an internal combustion engine is provided, which can carry out favorable injection amount feedback control even when a fuel property changes. A cylinder internal pressure sensor (16) that detects a cylinder internal pressure is included. A cylinder internal fresh air amount is calculated based on the cylinder internal pressure detected by the cylinder internal pressure sensor (16) (100). Based on the cylinder internal pressure detected by the cylinder internal pressure sensor (16), an actual heating value is calculated (120). From the calculated cylinder internal fresh air amount, a target heating value in a predetermined excess air ratio is calculated (150). A comparison value of the actual heating value and the target heating value is fed back to a fuel injection amount so that the calculated actual heating value corresponds to the target heating value (160, 170).

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.
