    • There is disclosed a valve timing controller having excellent response and used with an internal combustion engine. The controller performs a corrective control operation according to the oil pressure control characteristics of the actually mounted valve. The valve timing controller comprises an intake cam, an exhaust cam, an actuator for varying the phase of rotation of one of the cams relative to the crankshaft of the engine, an oil pressure control valve for applying oil pressure on the actuator, and a control means for controlling the valve timing by controlling the oil pressure output from the oil pressure control valve. The oil pressure output is controlled by controlling the current through the solenoid in the oil pressure control valve. The two cams are driven by the crankshaft of the engine. The intake cam opens and closes the intake valve. The exhaust cam opens and closes the exhaust valve. The control means detects the currents supplied into the solenoid to activate the actuator in different operating conditions of the engine. The characteristics of the oil pressure control valve are detected from the difference in the current value under these different operating conditions. An amount of control current is determined.

    • During the idling state, the number of times of injecting fuel per performance of the fuel delivery from a high-pressure fuel pump (47) is decreased or increased. If the number of times of injecting fuel per performance of the fuel delivery is decreased, the amount of fuel that needs to be delivered by one performance of the fuel delivery is reduced, so that the timing of starting to close an electromagnetic spill valve (54) can be delayed. Therefore, the lift of a plunger (48b) for 1 DEG rotation of a cam (22a) (i.e., cam speed) at the time of closure of the electromagnetic spill valve (54) decreases, so that the force applied from fuel to the electromagnetic spill valve (54) in the valve closing direction decreases. If the number of times of injecting fuel per performance of the fuel delivery is increased, the noises produced at the time of closure of the electromagnetic spill valve (54) increase because the timing of starting to close the spill valve (54) is advanced to increase the amount of fuel delivered by one performance of the fuel delivery. However, the number of times of closing the electromagnetic spill valve (54) during a predetermined period decreases, so that the number of occurrences of the valve closure noises decreases.
    • 在怠速状态期间,每次执行从高压燃料泵(47)输送燃料时喷射燃料的次数减少或增加。 如果每次执行燃料输送的喷射次数减少,则通过一次执行燃料输送而需要输送的燃料量减少,从而开始关闭电磁溢流阀(54 )可以推迟。 因此,在关闭电磁溢流阀(54)时凸轮(22a)旋转1°的柱塞(48b)的升程(即凸轮速度)减小,使得从燃料施加到 电磁溢流阀(54)在关闭方向上减小。 如果每次执行燃料输送时喷射燃料的次数增加,则在关闭电磁溢流阀(54)时产生的噪音增加,因为开始关闭溢流阀(54)的时间提前至 通过执行一次燃料输送来增加输送的燃料量。 然而,在预定时段期间关闭电磁溢流阀(54)的次数减少,使得阀关闭噪声的出现次数减少。 <图像>

    • 연료 공급 장치의 고압 연료 펌프(47)에 있어서, 캠(22a)이 단위 각도 회전할 때의 플런저(48b)의 이동량(캠 속도)은 캠(22a)의 위상에 따라서 변화한다. 고압 연료 펌프(47)의 연료 압송량은 전자 스필 밸브(54)의 폐쇄 밸브 개시 시기를 변경함으로써 제어되지만, 동일 폐쇄 밸브 개시 시의 캠 속도에 의해 크게 영향받게 된다. 그 때문에, 연료 분사에 필요량으로 되는 연료 압송량의 최대치가 얻어지는 전자 스필 밸브(54)의 폐쇄 밸브 개시 시기가 캠 위상 변화에 의한 캠 속도 변화가 일정해지는 소정 캠 각도 범위 내에 위치하도록, 예를 들면 캠(22a)의 캠 프로필이 설정된다. 그리고, 연료 압송량을 조정하기 위한 전자 스필 밸브(54)의 폐쇄 밸브 개시 시기 변경은 상기 소정 캠 각도 범위 내에서 행해진다.
    • 在燃料供给装置的高压燃料泵(47)中,在凸轮(22a)的单位角旋转期间发生的柱塞(48b)(凸轮转速)的移动量根据 凸轮(22a)。 通过改变电磁溢流阀(54)的关闭的开始时间来控制从高压燃料泵(47)输送的燃料量。 然而,所输送的燃料量受溢流阀(54)开始封闭时的凸轮转速的很大影响。 因此,例如,设置凸轮(22a)的凸轮轮廓,使得提供需要输送用于燃料喷射的最大量的燃料的电磁溢流阀(54)的闭合开始正时被放置在预定的 凸轮转速相对于凸轮(22a)的相位变化恒定的凸轮角度范围。 因此,在规定的凸轮角度范围内进行电磁溢流阀54的关闭开始时刻的改变,以调整输出的燃料量。
