摘要： A marine engine comprises a powerhead having an engine block, a cylinder head and a crankcase containing a crankshaft. Operation of the marine engine causes rotation of the crankshaft. A crankcase cover encloses the crankshaft in the crankcase. A supercharger is on the crankcase cover, the supercharger being configured to provide charge air for combustion in the powerhead. The supercharger comprises a charge air outlet for conveying charge air from the supercharger for combustion in the powerhead. A drainage port drains lubricant from the supercharger to the crankcase.

摘要： Returning engine oil to the primary oil sump from outboard locations in a flat engine can be a challenge. In the present disclosure, the pressure fluctuations occurring at the underside of the piston, due to reciprocation of the piston, are used to pump the oil from outboard locations to the primary oil sump. To prevent backflow of oil during periods of negative pressure difference, a check valve is placed in the oil drain passage. The check valve allows flow from the outboard location to the primary oil sump and no flow from the primary oil sump to the outboard location by opening and closing as driven by pressure fluctuations due to piston reciprocation. Such a check valve also prevents backflow of the oil to one of the outboard locations when the engine is tilted.
摘要翻译： 将发动机油从扁平发动机的外侧位置返回主油槽可能是一个挑战。 在本公开中，由于活塞的往复运动而在活塞的下侧发生的压力波动用于将油从外侧位置泵送到主油槽。 为了防止在负压差期间油回流，止回阀被放置在排油通道中。 止回阀允许从外侧位置到主油槽的流动，并且由于由于活塞往复运动的压力波动而驱动的打开和关闭，不会从主油底壳流到外侧位置。 当发动机倾斜时，这种止回阀还防止油向外侧位置的回流。

摘要： A lubricating system for a two-stroke engine is provided in which oil is more reliably pumped into the two-stroke engine. The oil travels through passages that are integrally cast into the cylinder and/or crankcase. The oil may be injected directly into the crankcase chamber or intake passage. The oil pump may be a rotary pump mounted on the crankcase concentric to the crankshaft. It is also possible to not use an oil pump, and have the oil drawn into the engine by vacuum created in the crankcase.

摘要： Disclosed is a lubrication device for a four-stroke engine, including three independent spaces which are crank room, cam room and lubricant room. A chamber is in communication with the three spaces respectively. A suction path assembly is located in the lubricant room and a plurality of suction holes are defined in the path assembly. An air inlet is defined in the suction path assembly. When the piston moves upward, the crank room is in a negative pressure status so as to suck air via the suction path assembly which is in communication with the crank room and the lubricant room by the chamber. The air flows fast in the suction path assembly and generates lower pressure so as to suck the lubrication oil which is then moisturized and sent into the crank room. When the piston moves downward, the crank room and the cam room are in communication with each other and the lubrication oil is sent into the cam room.
