摘要： A cam shaft of an engine is provided with a timing change mechanism (VVT) which is driven by hydraulic pressure to alter the timing of a intake valve (valve timing). This VVT is controlled to change the valve overlap of the intake valve and an exhaust valve, thereby adjusting the suction and exhaust in and from a combustion chamber. To control the VVT, an electronic control unit (ECU) computes a target value for the valve timing in accordance with the running condition of the engine and controls the supply of the hydraulic pressure to the VVT based on the target value. The ECU determines the level of the actual hydraulic pressure given to the VVT. When the actual valve timing does not lie in a predetermined range with respect to the target value, the ECU determines that an abnormality has occurred in the VVT, and executes a predetermined fail safe routine. When the hydraulic pressure is equal to or smaller than a reference value, the ECU suppresses WT malfunction determinations.

摘要： A varying mechanism (VVT) for continuously varying the valve timing of an intake valve in a predetermined range is provided on a cam shaft in an engine. By controlling the VVT, the valve overlap period of the intake valve and an exhaust valve is continuously varied in a predetermined range, thus adjusting the amount of the internal EGR in combustion chambers. When determining that the operational load of the engine is small and intermediate based on the value of a manifold pressure, an electronic control unit (ECU) computes a target value for advancing the valve timing with respect to the rotational phase of a crankshaft based on a throttle angle, an engine speed, etc. The ECU also computes a limit value to restrict the target value in accordance with the value of the manifold pressure. When the target value is smaller than the limit value, the ECU controls the VVT based on the target value. When the target value is greater than the limit value, the ECU replaces the limit value with target value and controls the VVT based on this target value.

摘要： An improvement of a valve timing control apparatus for an engine is disclosed. The apparatus has an intake valve and an exhaust valve which are alternately opened and closed in a valve timing sequence according to a rotation of a cam shaft. A timing pulley mounted on the cam shaft has a housing accommodating a plunger movable therein and a sleeve secured to the cam shaft. The housing has a first and second pressure chambers defined by the plunger and sealed with respect to each other. The plunger is arranged to move in an axial direction to selectively advance and retard the cam shaft based on differential pressure between the first pressure chamber and the second pressure chamber. A controller controls an electromagnetic valve with a specific control value to adjust the fluid pressure to be supplied to the first and second pressure chambers to maintain the valve timing sequence converged to a target valve timing. The controller corrects the specific value based on a rotational speed of the engine when the plunger is in one of the extreme positions in the chambers, and adjusts the fluid pressures based on the corrected specific value.

摘要： Disclosed is a device for calculating an amount of an air introduced to a cylinder of an engine. An air-intake passage introduces the air to the cylinder. An air-exhaust passage exhausts gas from the cylinder. Both passages respectively have an intake valve and an exhaust valve. Both valves are respectively driven by an intake valve drive mechanism and an exhaust valve drive mechanism in accordance with a rotation of a crank shaft to alternatively and selectively open and close, and simultaneously open during a valve overlap period to open the passages to the cylinder. A variable valve timing mechanism controls an operational timing of the valve drive mechanisms with respect to the crank shaft in accordance with a running condition of the engine to vary a timing of the valve driven by the valve drive mechanisms. The calculating device comprises a first detecting device, which detects a rotational speed of the crank shaft. A second detecting device detects an intake pressure in the air-intake passage. A third detecting device detects the operational timing of the valve drive mechanisms. A calculating device calculates a displacement of the operational timing according to the detected rotational speed of the crank shaft and the detected operational timing. A first computing device computes the amount of the air introduced to the cylinder in response to the rotational speed of the crank shaft, the intake pressure, and the displacement of the operational timing.
