    摘要： A drive plate assembly includes a plate member adapted for mounting to an engine block. The plate member has first and second gears mounted thereto such that they intermesh. The backlash of the gears is predetermined by mounting to the plate member and unaffected by mounting the plate member to the engine block. A method of assembling a powertrain is also provided.

    摘要： An engine drive assembly includes a camshaft gear, and a first idler gear engaged with the camshaft gear. The engine drive assembly further includes a crankshaft gear engaged with the first idler gear and a second idler gear assembly engaged with the crankshaft gear. Additionally, the engine drive assembly includes a balance shaft gear engaged with the second idler gear. The crankshaft gear drives the camshaft gear via the first idler gear and the crankshaft gear drives the balance shaft gear via the second idler gear assembly.

    摘要： The rotary valve assembly of the present invention employs a rotary valve body member that is rotatably mounted in a cylindrical opening in a valve casing forming the head above a piston. The axis of this opening and the rotary valve are perpendicular to the axis of the piston and its associated cylinder walls. The intake and exhaust ports are openings that pass through the valve casing from its outer edge to the cylindrical opening containing the rotary valve. There is also a cylinder port between the cylindrical opening in the valve casing and the cylinder containing the piston. The rotary valve body has a circular cutout or scoop portion removed therefrom to allow intake gases to flow from the intake port via this cutout into the cylinder port and then into the cylinder. This same cutout also allows gases to pass from the cylinder port into the exhaust system via the exhaust port. The rotary valve is preferably integral with and driven by a shaft mounted in sealed bearings (mounted in the valve casing) and the shaft is in turn driven mechanically by appropriate coupling to or with the crankshaft. There is no metal-to-metal contact between the rotary valve body and the opening in the head and thus, no need for a separate lubrication supply. The cylindrical opening in the head contains a plurality of non-metallic sealing members which contact the rotary valve body. The rotary valve body has spacers on both sides to prevent metal-to-metal contact with the walls of the cylindrical opening.

    摘要翻译： 本发明的旋转阀组件采用旋转阀体构件，其可旋转地安装在形成在活塞上方的头部的阀壳中的圆柱形开口中。 该开口的轴线和旋转阀垂直于活塞的轴线及其相关联的气缸壁。 进气和排气口是通过阀壳从其外边缘到包含旋转阀的圆柱形开口的开口。 在阀壳体中的圆柱形开口和容纳活塞的气缸之间还有一个气缸口。 旋转阀体具有从其移除的圆形切口或勺部，以允许进气从进气口经由该切口流入气缸端口，然后进入气缸。 同样的切口也允许气体通过排气口从气缸口进入排气系统。 旋转阀优选地与安装在密封轴承（安装在阀壳体中）的轴一体并由其驱动，并且轴通过适当地联接到曲轴或与曲轴一起被机械地驱动。 旋转阀体与头部开口之间没有金属对金属的接触，因此不需要单独的润滑电源。 头部中的圆柱形开口包含与旋转阀体接触的多个非金属密封构件。 旋转阀体在两侧具有间隔件，以防止金属与金属与圆柱形开口的壁接触。

    摘要： Arrangements for stabilizing valve timing adjustment mechanisms such as cam phasers during operation of an engine are described. The described approaches are particularly well suited for use during skip fire control, although they may be used advantageously in other applications as well. In general, the phase of an adjustable phase camshaft is controlled relative to a crankshaft of an engine. In one aspect, at least one of (i) firing events in a skip fire firing sequence, and (ii) dynamically determined valve actuation events are used in the control of the camshaft phase during operation of the engine. In some embodiments, hydraulic pressure within a cam phaser is varied in a manner that maintains the phase of the camshaft substantially more stable through transitory variations in torque applied to the camshaft by the actuation of the valves than would occur without the variations in hydraulic pressure.

    摘要： A camshaft assembly may include a first shaft adapted to be rotationally driven, a first lobe member fixed for rotation with the first shaft, and a torsional damper fixed to the first shaft. The torsional damper may include a mass structure fixed to the first shaft and an elastic member disposed between and coupling the mass structure and the first shaft. The elastic member may have a spring constant providing a first sideband natural frequency and a second sideband natural frequency for the camshaft assembly.
