摘要： An air cleaner system for small internal combustion engines (20), including a removable or replaceable air cleaner element (72) detachably mounted within an air cleaner cavity (70) which is defined at least in part by the shroud (26) of the engine. The air cleaner element includes engagement structure (82) for releasable engagement with a wall (44) of the air cleaner cavity to permit mounting of the air cleaner element within the cavity, and removal of the air cleaner element from the cavity, without the use of tools. In addition, a cover (60) is provided for releasably engaging the air cleaner cavity to cover the air cleaner element.

摘要： A compression release mechanism (20) for use in a single or multi-cylinder engine to make the engine easier to hand start. The assembly (20) includes a compression release shaft (32) disposed substantially within the camshaft (22). The compression release shaft (32) is formed in at least two segments (34, 36) and can therefore be formed accurately, repeatedly and cost effectively using powder metal technology. Consequently, the weight of the flyweight member (38) that is attached to the compression release shaft (32) can be accurately controlled, thereby allowing the compression release mechanism (20) to disengage at a precisely known rotational velocity of the camshaft (22). The compression release shaft (32) may engage one or more valve actuation devices (28), which in turn force exhaust valves (80) open during starting engine speeds. The compression release mechanism (20) is conveniently contained within the housing (64) by a housing wall (65) bearing against the flyweight member (38) and a cam (24) bearing against an end of the compression release shaft (32). These bearing surfaces (65, 68) also hold the compression release shaft segments (34, 36) together.
摘要翻译：一种用于单缸或多缸发动机的压缩释放机构（20），用于使发动机更易于手动启动。组件（20）包括基本设置在凸轮轴（22）内的压缩释放轴（32）。压缩释放轴（32）形成为至少两个区段（34,36），并且因此可以使用粉末金属技术精确地，重复地且成本有效地形成。因此，能够准确地控制安装在压缩解除轴32上的飞摆构件38的重量，能够以凸轮轴22的精确已知的旋转速度使压缩解除机构20脱开，。压缩释放轴（32）可以接合一个或多个阀致动装置（28），这继而在起动发动机速度期间迫使排气阀（80）打开。压缩释放机构（20）通过抵靠飞摆构件（38）的壳体壁（65）和抵靠压缩释放轴（32）的端部的凸轮（24）方便地容纳在壳体（64）内。这些支承表面（65,68）也将压缩释放轴段（34,36）保持在一起。

摘要： A twin cylinder engine (50, 300), includes a pair of cylinder members (74a, 74b) mounted to mounting surfaces (72a and 72b) of a crankcase (52), and cylinder heads (96, 324) mounted to the cylinder members. The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear (156) which extends into the crankcase for driving engagement with the crankshaft (58). The cylinder members may be configured for either side valve-type ("L-head"), or overhead valve-type ("OHV") engines, and the cylinder members may also be used in single cylinder engines.

摘要： A line of small internal combustion engines (50, 300, 400, 500, 600, 700), including twin cylinder engines (50, 300,400) and single cylinder engines (500, 600, 700). The engines each include a crankcase (52, 302, 402, 502, 602, 702), and one or more cylinder members (74, 306) attached to the crankcase, the cylinder members being separate components from the crankcase. A number of different crankcases are provided for various types of single and two cylinder engines, the crankcases having common mounting structure (72, 76) to which the cylinder members may be attached. Thus, the manner in which the cylinder members are attached to the crankcases is the same for each of the different types of crankcases. Two different types of cylinder members are provided, one having a side valve or "L-head" valve train (110), and the other having an overhead cam ("OHV") valve train (332). The cylinder members are therefore modular components which may be selectively used in a variety of different types of engines.
