    摘要： A compression release mechanism for small internal combustion engines, including a compression release member having an auxiliary cam and a weight section. The compression release member is supported for rotation on an annular bearing surface which is in eccentric relation to the longitudinal axis of the engine camshaft. At engine cranking speeds, the compression release member rotates with the camshaft, and the auxiliary cam projects beyond the base circle of a cam lobe on the camshaft to periodically engage a valve to vent pressure from the engine combustion chamber during the compression stroke of the piston to aid in engine cranking. After the engine starts, rapid rotation of the camshaft causes the compression release member to rotate under the inertial load of the weight section thereof to a position in which the auxiliary cam is retracted within the base circle of the cam lobe such that combustion may proceed in a conventional manner.

    摘要： An air cleaner system for small internal combustion engines, including a removable or replaceable air cleaner element detachably mounted within an air cleaner cavity which is defined at least in part by the shroud of the engine. The air cleaner element includes engagement structure for releasable engagement with a wall 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 is provided for releasably engaging the air cleaner cavity to cover the air cleaner element.

    摘要： First and second valve-operating characteristic changing mechanisms for changing the valve lift and the valve timing of an intake valve respectively are provided on an intake side of an engine. A hydraulic pressure control valve for the first valve-operating characteristic changing mechanism is mounted on one side of a cylinder head, and an oil filter for the second valve-operating characteristic changing mechanism is mounted on the other side of the cylinder head. The hydraulic pressure control valve and the oil filter are mounted outside a chain cover covering a timing chain. Therefore, the control valve and the oil filter do not interfere with the timing chain, and the maintenance of the control valve and the oil filter is carried out without removal of the chain cover.

    摘要： The invention relates to new and useful improvements in dual-cycle engine design and construction. The invention enhances the mechanical ability of such engines to automatically match the engine cycle with the load conditions while the system is in operation in a manner which significantly reduces the specific fuel consumption. Using the standard L-head engine configuration, the upper cylinder manifolding and the lower cylinder manifolding are combined as single flow channels reducing the number of components required to sequence flow to and from the engine. Combining the upper and lower cylinder manifold circuits standardizes the operating pressures in each system improving exhaust gas ejector efficiencies, facilitating engine control, and simplifying the application of pressure boosting in the air induction circuit. These improvements reduce the design complexity and simplify the automatic transition from 4-stroke to 2-stroke operation. Other benefits of the invention are the reduction of manufacturing costs, decreased engine weight and smaller system envelope.
