    Abstract: PURPOSE:To to make it possible to use a miniature and lightweight motor, by driving a step motor to control the velve timing, when a cam shaft is given a reaction force from a valve spring along the positie rotating direction. CONSTITUTION:Whether the number of steps is increased in order to advance the valve timing, or the number of steps is decreased in order to delay the valve timing, is decided by the first discriminative means 5 based on output signals from an intake air quantity sensor 2 and an engine speed sensor 3. And then, whether it is the crank time for that a cam shaft is given a reaction force from a valve spring along the positive rotating direction, or not, is decided by the second discriminative means 7 based on a signal output from a crank angle sensor 6. Pulse is fed so that a step motor 4 is driven by the number of steps output from the first discriminative means, at the time the cam shaft is given a reaction force along the positive rotating direction. As the step motor 4 is driven when the load is small, a miniature/lightweight motor is enough to use, and the consumption of electric power can be decreased.

    Abstract: PURPOSE:To detect an accurate phase difference between a crankshaft and a camshaft by a method wherein pulse generators are respectively arranged on the camshaft and on the crankshaft and the phase difference is calculated from the interval between the adjoining pulses of said pulse generators and the rotational frequency of an engine. CONSTITUTION:A pulse generator, which generate a pulse every time a crankshaft makes a turn, consists of an indicator piece 62 on a crankshaft 10 and a magnetic sensor 64 facing to the piece 62 and a pulse generator, which generates a pulse every time a camshaft makes a turn, consists of an indicator piece 66 on a camshaft 18 and a magnetic sensor 68 facing to the piece 66. The two magnetic sensors 64 and 68 are connected through wires 70 and 72 to a control circuit 74, which has a function to calculate the phase difference based upon the pulse signals from said pulse generators. The sensor 68 on the camshaft 18 issues one signal every time the sensor 68 faces to the indicator piece 66 correctly during one turn of the camshaft. Similarly, the sensor 64 on the crankshaft 10 issues one signal every time the sensor 64 faces to the indicator piece 64 correctly during one turn of the crankshaft. Consequently, the phase difference is detected and can be accurately measured by measuring the time interval between the adjoining pulses and the rotational frequency of an engine.

    Abstract: 【課題】この発明は、内燃機関の制御装置に関し、複数の気筒のバルブ駆動カムのプロフィールを切り替えるカム切替動作を行った際に、一部の気筒もしくは気筒群でプロフィールの切り替えに失敗したとしても、気筒間もしくは気筒群間でバルブ駆動カムの異なるプロフィールが混在する確率を下げられるようにする。 【解決手段】ECUは、複数の気筒のそれぞれのバルブ駆動カムのプロフィールを第1プロフィールから第2プロフィールに切り替えるための第1カム切替動作をカム切替機構に実行させたにもかかわらず複数の気筒のすべてのバルブ駆動カムのプロフィールが第2プロフィールで揃わない場合に、第2プロフィールへのプロフィールの切り替えが成功した1または複数の気筒である1または複数の正常気筒を少なくとも対象として、バルブ駆動カムのプロフィールを第1プロフィールに切り替えるための第2カム切替動作をカム切替機構に実行させる。 【選択図】図7
