Abstract: The piston of this invention is so profiled that the diametric reduction of the shoulder portion of the skirt is greater on the thrust side than on the counter-thrust side and that the difference in diametric reduction between the thrust side and the counter-thrust side is maximum at around a position corresponding to the center of the piston pin. In the compression stroke, the piston moves up pressed against the cylinder liner wall on the counter-thrust side but the inclination angle of the piston at this time is small. Near the top dead center, the piston is rapidly pivoted and strikes against the cylinder liner wall on the thrust side. The point on the piston hitting the cylinder liner wall is at around a position equal in height to the center of the piston pin. This reduces the impact force of the piston and therefore the slap.
Abstract translation: 本发明的活塞是这样的，使得裙部的肩部的直径减小在推力侧比反推力侧更大，并且推力侧和反推力侧之间的直径减小的差异是 在与活塞销的中心对应的位置处的最大值。 在压缩行程中，活塞向上压靠在反推力侧的气缸套壁上，但此时活塞的倾斜角度较小。 在上止点附近，活塞迅速枢转并撞击推力侧的气缸套壁。 活塞撞击气缸套壁的点位于与活塞销中心高度相等的位置。 这就降低了活塞的冲击力，从而降低了冲击力。

Abstract: An intake air throttle valve control system for a diesel engine which greatly reduces vibration, noise and rough engine running at idling speeds. An intake passage connected in series with the intake manifold of the engine is divided into first and second parallel intake passages. A throttle valve is disposed in a first intake passage to provide a throttling effect therein in response to predetermined engine conditions such as engine temperature, oil line pressure and/or exhaust manifold pressure. A negative pressure control valve is disposed in the second passage to maintain a negative pressure downstream of first and second passages at a fixed value to prevent the pressure from being overly reduced by the throttle valve.

Abstract: An intake air throttle valve control system for a diesel engine which greatly reduces vibration and noise and rough engine running at idling speeds. A throttle valve is provided in an intake passage in series with the intake air manifold of the engine with the valve operated by a negative pressure responsive actuator. The negative pressure responsive actuator is coupled to a source of negative pressure through a series-connected arrangement of a water temperature sensing valve, a vacuum cut-off valve and a negative pressure control valve. The water temperature sensing valve operates to connect or disconnect the source of negative pressure to the actuator in response to the temperature of the engine coolant. The vacuum cut-off valve vents the connections to the actuator to the atmosphere in response to an engine operating parameter such as the exhaust manifold pressure, the pressure in an oil line of the engine, or an output voltage of a generator which varies in response to the engine speed. The negative pressure control valve introduces atmospheric pressure into the system in proportion to the magnitude of negative pressure in the intake manifold downstream of the throttle valve.
