    摘要: A control device includes a valve system which can selectively operate at least one of an intake and exhaust valves of an automobile engine by means low speed cams 12 or high speed cams 13. It further includes an engine speed detecting device; and operation mode determining device for determining whether the engine is in a low or high speed operation mode based on engine speed data, and for producing a signal indicative of a current operation mode. The control device varies a fuel supply suspending engine speed for each operation mode based on the signal from the operation mode determining device, and issues a fuel-supply suspending command when the current engine speed is above the fuel supply suspending engine speed. An optimum fuel supply suspending engine speed is set for each engine operation mode, so that the valve system can operate reliably even when operation mass applied thereto varies.

    摘要: A valve operating apparatus, which transmits the rotation of the crankshaft of an automotive engine to the intake and exhaust valves to open and close the valves, can selectively vary the timing to open and close the valves and ther lifts of the valves. The valve operating apparatus includes a camshaft with low- and high-speed cams and low- and high-speed rocker arms, one of which is fixed to and the other rotatably supported on a rocker shaft. The valves can be opened and closed by the low-speed rocker arm. The other rocker arm and the rocker shaft can be engaged and disengaged by an engaging mechanism that is actuated by an actuating mechanism depending on the operating condition of the engine.

    摘要: An internal combustion engine includes: a variable valve train mechanism, configured to receive a cam displacement of an inlet cam so as to vary a driving output for driving an inlet valve continuously from a maximum valve lift to a minimum valve lift so as to match the driving output with a running condition of the internal combustion engine; and a control part, configured to control the variable valve train mechanism so as to set a valve lift of the inlet valve to a starter valve lift when starting the internal combustion engine in a cold state. The starter valve lift is formed so that a valve opening period of the inlet valve is set to encompass an overall area of an induction stroke period of the internal combustion engine from a top dead center to a bottom dead center of the induction stroke period.
