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： When a displacement of an armature of an electromagnetically driven valve fails to reach a predetermined threshold value even after an elapse of a predetermined time from switching opening/closing of the valve, it is determined that step-out has occurred or step-out is about to occur and then the valve opening/closing control is changed. The valve opening/closing control is changed, for example, by interrupting application of current to the valve for attracting the armature released from the other valve.

摘要： A rush adjuster which adjusts a relative position between a valve body and an armature in an axial direction so that a state of zero-rush is formed is arranged between an armature shaft and a valve shaft. At a time of starting an electromagnetic drive valve, a first starting current is applied to either one of an upper coil and a lower coil for generating electromagnetic forces for attracting the armature closer, whichever a distance with respect to the armature is shorter.

摘要： An internal combustion engine having an electromagnetic valve driving mechanism adjusts an amount of magnetizing current to be applied to the electromagnetic valve driving mechanism in accordance with a temperature or viscosity of a lubricant used in the electromagnetic valve driving mechanism. Accordingly, intake and exhaust valves can be driven with an electromagnetic force corresponding to a viscosity of the lubricant. Therefore, changes in opening-and-closing operation speeds of the intake and exhaust valves resulting from a temperature or viscosity of the lubricant that is supplied to a sliding portion of the electromagnetic valve driving mechanism can be reduced.
