    • A valve timing control system for an internal combustion engine, which precisely learns the maximum retard position thus making fine valve timing control possible. The control system includes a learning unit for learning a phase difference between the cam angle and the crank angle when a valve overlap between an intake valve and an exhaust valve is at a minimum, a learning instructions transmitting unit for transmitting to the learning unit, a learning instruction for learning the phase difference between the crank angle and the cam angle, and a valve timing control variable calculating unit for calculating a valve timing control variable, for varying the valve timing, on the basis of a deviation between the learned value and the present phase difference between the crank angle and the cam angle. The learning instruction transmitting unit is used only before shipment of a motor vehicle equipped with the internal combustion engine or upon mechanical inspection thereof. The learning unit learns the phase difference between the crank angle and the cam angle only when receiving the learning instruction from the learning instruction transmitting unit.

    • A multi-cylinder internal combustion engine with at least one cylinder row is equipped with a cylinder head housing containing intake and exhaust valves that feed combustion air to the cylinders and release combustion exhaust gases through an exhaust system via control devices in dependence of the position of the crankshaft. Devices for generating differing exhaust valve lift progressions of at least two cylinders arranged in one cylinder row are incorporated to reduce overlapping opening phases of these exhaust valves. The intake valve and the exhaust valve of one of the two cylinders are themselves in an overlapping opening phase. Thereby, a uniform filling rate of the cylinders with new gas is achieved, particularly on a V-8 engine with a 90°-bent crankshaft.

    • To exactly obtain a volumetric efficiency or ignition timing corresponding to a shift amount in rotational angle or phase of a camshaft relative to a crank shaft operably connected therewith even if the opening/closing timing of an exhaust valve and an intake valve is changed so as to optimally control an fuel injection amount or ignition timing, the fuel injection amount or the ignition timing is controlled by calculating a fuel control parameter or an ignition timing control parameter on the basis of an intake pressure and a rpm of the engine. When the valve timing is changed, the amount of change in the valve timing is detected so that the fuel control parameter or the ignition timing control parameter is compensated for on the basis of the change amount thus detected.
