Abstract
An oil-cooled engine assembly is provided for cooling lubricating oil, which has lubricated movable parts of an engine and subsequently recirculating cooled lubricating oil to the movable parts. The engine assembly includes a lubricating oil pump contained in the engine, and a hollow frame body which supports the engine. The hollow frame body has an oil passage through which lubricating oil flows. The lubricating oil pump is connected to the oil passage. Lubricating oil, which has lubricated the movable parts of the engine is air cooled with the frame body. Cooled lubricating oil is circulated again to the movable parts of the engine.
Claims13
An oil-cooled engine assembly comprising:
- an engine;
- a lubricating oil pump disposed within the engine;
- a hollow frame body which surrounds the engine and engine accessories including a carburetor and a muffler, supports the engine, and is internally formed with an oil passage through which a lubricating oil flows;
- a plurality of cover plates covering the frame body, one of the cover plates having an intake port;
- and
- a cooling fan mounted to a crank shaft of the engine for drawing in outside air through the intake port;
- the lubricating oil pump being connected to the oil passage so that after lubricating movable parts of the engine, the lubricating oil is air cooled by the frame body and then returned to circulation for lubricating the movable parts of the engine again.
An oil-cooled engine assembly, comprising:
- an engine having movable parts that require lubrication during use of the engine;
- a hollow frame body supporting therewithin the engine and defining inside thereof an oil passage for storing and flowing a lubricating oil;
- a lubricating oil pump disposed within and driven by the engine, the lubricating oil pump being connected to the oil passage for circulating the lubricating oil from the engine through the oil passage and then back to the engine to thereby lubricate the movable parts of the engine accompanied by heating of the lubricating oil which, in turn, heats the frame body;
- and a plurality of cover plates covering the frame body for dissipating heat from the frame body and thus from the lubricating oil while the lubricating oil circulates through the oil passage.
