    Abstract: A system for the just-in time scheduling of camshaft timing for an internal combustion engine. A slave circuit generates an execution period corresponding to the execution period of the variable camshaft timing mechanisms. The control processor initiates the calculation of a correction signal base on the difference between the desired camshaft timing and the actual camshaft timing synchronous with the execution period of the variable camshaft timing mechanism. The calculation of the correction signal is executed by the central processing unit once and only once for each execution period of the variable camshaft timing mechanism.

    Abstract: A diagnostic system makes a diagnosis on a variable valve timing control system mounted on an internal combustion engine by forcibly switching the valve timing control system from an operative state to an in operative state. The diagnostic system comprises sensors for detecting a variation of an operating state of an internal combustion engine, based on the forcible switching operation, and for detecting a throttle valve opening of the engine. The diagnostic system makes the diagnosis by comparing a variation of rate of flow of intake-air with a predetermined reference value to determine whether the valve timing control system operates normally or abnormally. The diagnostic system provides both a predetermined diagnostic preparatory period and a predetermined actual diagnostic period. The diagnostic system calculates a variation of the throttle valve opening, varied from the throttle valve opening detected at the beginning of the predetermined diagnostic preparatory period before the forcible switching operation, and inhibits the diagnosis of the valve timing control system when the variation of the throttle valve opening exceeds a predetermined threshold.

    Abstract: A VRS sensor detects the angular rotation of a variable position camshaft which rotates in a variable relationship to a crankshaft, and transmits a Variable Cam Timing/Cylinder IDentification signal, representative of the position of the angular rotation of the camshaft, to an electronic engine controller (EEC). A profile ignition pickup (PIP) sensor detects the rotation of the crankshaft and transmits a PIP signal, representative of the rotation of the crankshaft to the EEC. The EEC receives the VCT/CID signal and the PIP signal and identifies the position of a first firing cylinder in a predetermined sequence of cylinder firing and determines the angular position of the camshaft in relation to the crankshaft by detecting the varying time duration between VCT/CID signals and PIP signals.

    Abstract: A valve timing control device for an internal combustion engine. The device comprises a variable valve timing mechanism capable of varying a valve overlap period; an increasing unit capable of increasing an amount of intake air in at least the idle condition; a determination unit for determining an optimal value of the valve overlap period in the current engine operating condition, on the basis of current engine speed, load, and temperature; a first controller for controlling the variable valve timing mechanism such that the valve overlap period becomes larger than the optimal value in an idle condition when the engine has not warmed up; and a second controller for controlling the increasing unit such that an amount of intake air is increased in an idle condition when the engine has not warmed up. Accordingly, in the idle condition when the engine has not warmed up, intake air is heated sufficiently, by the valve overlap period, to more than the optimal value and engine stall at such time is completely prevented by increasing the amount of intake air.

    Abstract: 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.
