It is intended to provide a compact and lightweight outboard engine and to prevent its output loss by preventing or minimizing lubricant oil staying in a crank chamber while the engine is driven in a tilt-up condition. For this purpose, the outboard engine...

An engine lubrication system has an arrangement in which the base of a crankcase (2) is used to form an oil reservoir (30), and a part of an oil slinger (31) that is driven by a crankshaft (1) via a transmission system (33) is immersed in the oil within th...

An oil-cooled engine assembly is provided for cooling lubricating oil (O), which has lubricated movable parts of an engine (11) and subsequently recirculating cooled lubricating oil to the movable parts. The engine assembly (10) includes a lubricating oil ...

The IC engine has the different auxiliary systems for operation of the engine, e.g. the cooling system and the cooling pump, the fuel system and the fuel pump and the lubrication system and the lubrication pump, each provided as a modular component and dri...
