Abstract

An apparatus for draining oil from an engine. The apparatus includes an engine having an engine housing, crankshaft, a piston, and an oil reservoir, an engine starting mechanism configured to engage the crankshaft and piston, a check valve configured to prevent pressure in a crankcase from escaping and configured to allow filtered air into the engine, and a selector valve configured to open a flow path between the check valve and a vent so oil can be drained.

Description

technical field [0001] The invention relates to a lubrication system for an internal combustion engine. More specifically, the present invention relates to an oil removal system and method for an internal combustion engine. Background technique [0002] In internal combustion engines, including those used in lawnmowers, snow blowers, or other outdoor powered equipment, the oil should be drained and replaced periodically to maintain optimum engine performance. In these applications, the engine is usually mounted to a frame, such as a lawn mower deck. When it is desired to drain the engine oil, the oil is usually drained through a drain hole located near the bottom of the engine, or by tilting the device so that the oil can be drained from the drain hole. This method sometimes requires handling very heavy equipment and uses gravity to drain the oil and often results in spills. Contents of the invention [0003] In one embodiment, the invention provides an apparatus for dr...
