摘要： An oil system for a two-stroke outboard marine engine is disclosed. The oil system includes an oil system housing having an inlet, an outlet, and an oil return. The housing includes an oil filter base to receive a replaceable oil filter thereon. The oil is routed in a closed loop that includes an oil reservoir, the inlet to the oil system housing, through the replaceable oil filter, and is then returned to the oil reservoir. Periodically, a solenoid opens the closed loop system to divert oil to the two-stroke engine, at which time a remote vent valve is activated to allow air to enter the oil reservoir to displace the dispensed oil.

摘要： A marine propulsion unit comprises a cylinder (1), a combustion chamber (2) extending from one end of the combustion chamber, a spark plug (8) provided in the combustion chamber (2), and a piston (5) mounted for reciprocating movement within the cylinder (1). A first port (9) is provided in the combustion chamber (2), and this is selectively openable independent of the position of the piston (5) within the cylinder (1). If the propulsion unit should be immersed in water so that the cylinder becomes flooded, the cylinder can be purged by opening the port (9) and moving the piston (5) so as to expel water through the port (9). Once all water has been expelled further movement of the piston causes gases in the cylinder to pass over the spark plug thus removing trapped water from the spark plug without the need to remove the spark plug from the engine to dry it. The location of the first port is chosen so as to maximise as far as possible the flow of gas over the spark plug (8), to minimise the time taken to remove trapped water from the spark plug. Once the spark plug has been dried sufficiently to allow ignition to be achieved, the propulsion unit can be restarted. A second port (10) can also be provided to improve drainage of the engine.
摘要翻译：一个船舶推进装置包括一个气缸（1），一个从燃烧室一端延伸的燃烧室（2），设置在燃烧室（2）内的一个火花塞（8）和一个活塞（5）在气缸（1）内的运动。第一端口（9）设置在燃烧室（2）中，并且其独立于活塞（5）在气缸（1）内的位置选择性地打开。如果推进单元应浸入水中以使气缸淹没，则可以通过打开端口（9）并移动活塞（5）来清洗气缸，以便通过端口（9）排出水。一旦所有的水被排出，活塞的进一步运动就会导致气缸中的气体越过火花塞，从而从火花塞中除去被捕获的水，而不需要从发动机上去除火花塞以将其干燥。选择第一端口的位置以尽可能地最大限度地使火花塞（8）上方的气体流最大化，以最小化从火花塞移除捕获的水所需的时间。一旦火花塞已被充分干燥以便能够实现点火，则可以重新启动推进装置。还可以设置第二端口（10）以改善发动机的排水。

摘要： A water pressure and volume regulator for a marine engine includes a regulator body having a flow path defined therethrough. A piston is mounted along the flow path and is normally biased toward a closed position to block the passage of water along the flow path through the regulator. As the pressure within the water flow exceeds the biasing force urging the piston toward its closed position, the flow path is opened to enable to passage of excess water therethrough to help regulate and maintain a desired pressure of the water flow as it is supplied to the marine engine.
