    摘要: An internal combustion engine is provided with a variable valve train capable of altering opening and closing timings and/or opening amounts of at least one of an intake valve and an exhaust valve of an internal combustion engine. The internal combustion engine is characterized in that the internal combustion engine is further provided with a negative pressure mechanism that operates using intake pipe negative pressure generated in an intake passage of the internal combustion engine, a throttle valve for adjusting the flow rate of intake air flowing through the intake passage, and negative pressure generating device that controls at least one of the variable valve train and the throttle valve to generate the intake pipe negative pressure, when the intake pipe negative pressure for operation of the negative pressure mechanism is insufficient.

    摘要: A control method with variable feedback gain for energization of an electro-magnetically driven intake/exhaust valve of an internal combustion engine increases opening and closing speeds of the intake/exhaust valve driven with electromagnets having small capacity and brings the final speed of the opening and closing action of the valve close to zero. A target moving speed of the armature relative to the electromagnets is determined dependent upon a spacing distance of the armature from the electromagnet; at least a part of energization of the electro-magnetically driven valve is controlled through feedforward control so as to make an actual moving speed of the armature relative to the electromagnets in conformity with the target moving speed while at least the other part of the energization is controlled through feedback control based upon a deviation of the actual moving speed from the target moving speed.

    摘要: A method of operating an internal combustion engine having an; electromagnetically driven intake valves for a vehicle. With the method, deviation of an opening operation of the electromagnetically driven intake valve in response to a command signal for opening the intake valve from a predetermined characteristic is detected, and at least one of parameters used for controlling operation of the internal combustion engine is corrected so as to reduce a change in an intake air charging state in which the internal combustion engine is charge with the intake air. A valve closing timing of the intake valve or a valve closing timing of the exhaust valve that cooperates with the intake valve may be used as parameters to be corrected.
