Abstract: An internal combustion engine comprising a crankshaft rotatable about an axis, one or more pairs of cylinders opposed from each other on either side of the crankshaft, one or more pairs of pistons alternately moveable within the cylinders by combustion therein, and a common rod connecting the pair of pistons, the pistons and common rod being linearly slideable in a first direction. A linear bearing is disposed on the common rod between the pair of pistons and connects the common rod to the crankshaft, the linear bearing being slideable in a second direction normal to the first direction. As the pair of pistons alternately move within the cylinders, the crankshaft is driven by movement of the common rod and pair of pistons back and forth in the first direction and movement of the linear bearing back and forth in the second direction.

Abstract: Classic two stroke valve-less petrol engine, which operates without added lubricating oil to the fuel-air mixture. The above mentioned invention is applicable in the motorcycle industry, automotive industry, water sports industry, mechanical industry and other industries which need and use engines to power machinery and equipment to perform their functions. The well known positive qualities of the current two stroke engine make it desirable in numerous applications and uses, however its two major drawbacks (pollution from exhaust gasses containing unburned oil and greater fuel consumption) limit the scale of its utilization. The invention design of the petrol two stroke engine allows for the exhaust gasses to comply with the acceptable pollution levels, to increase the power output of the engines (due to the fact that lubrication oil, which until present was required by the former design, is absent from the air-fuel mixture) and to reduce the fuel consumption. Another factor in improving the technical characteristics of the engine is the embedded rotor plate/vane compressor which has the optimal capability for air induction at low, as well as at high rpm (rotations per minute). The optimal efficiency of the engine is achieved with the assistance of additional mechanisms and electronic devises for regulation of the air flow to the cylinder.

Abstract translation: 经典的两冲程无阀汽油发动机，其运行时不需要向燃油空气混合物添加润滑油。 上述发明适用于摩托车行业，汽车行业，水上运动行业，机械行业等需要使用发动机驱动机器设备履行职能的行业。 目前的两冲程发动机的众所周知的积极特性使其成为许多应用和用途的理想选择，然而其两个主要缺点（含有未燃油的废气的污染和更大的燃料消耗）限制了其使用规模。 汽油两冲程发动机的发明设计允许废气符合可接受的污染水平，以增加发动机的功率输出（由于前一设计所要求的直到现在的润滑油是 不存在于空气 - 燃料混合物中）并且减少燃料消耗。 提高发动机技术特性的另一个因素是嵌入式转子板/叶片压缩机，它具有最低的空气感应能力以及高转速（每分钟转数）的最佳能力。 发动机的最佳效率是通过额外的机构和电子装置的协助来实现的，用于调节气缸的气流。

Abstract: An apparatus for adjusting power and noise characteristics of an internal combustion engine comprises a wall configured to define an engine cylinder that includes a bore and a compression relief passage. A compression relief valve is configured to selectively adjust fluid flow capacity of the compression relief passage. A manifold is configured to be in fluid communication with the exhaust passage and includes an exhaust bypass valve to permit exhaust to at least partially bypass a noise suppressor. Operational characteristics of the engine can be adjusted along a range that extends from a first set of operational characteristics present when both the compression relief valve and the exhaust bypass valve are in a fully open position to a second set of operational characteristics present when both the compression relief valve and the exhaust bypass valve are in a fully closed position.
