Abstract
An engine lubrication and speed control method is provided. The four-cycle engine has a engine block having a cylindrical bore and an enclosed oil reservoir formed therein. A vertical or horizontal crankshaft is rotatably mounted in the engine block for rotation about a crankshaft axis. An oil pump, which is driven by the camshaft connected with a cam gear or driven by the crank shaft connecting with the crank gear, inhales the oil from the oil reservoir to splash lubricate into the cylinder bore and valve chamber. A speed control governor is provided on the wall of the cylinder block. The engine is provided with a cylinder head assembly defining a compact combustion chamber having a pair of overhead intake and exhaust ports and cooperating intake and exhaust valves. A commonality of parts between the horizontal and the vertical engine is highly achieved.
