ABSTRACT:
An engine crankcase has oppositely inclined surfaces thereon, to which cylinders equipped with cooling fins are attached, to form a V-shaped engine. The crankcase has a crankshaft rotatably mounted therein, the front end of which projects from the front of the crankcase and has a cooling fan mounted thereon, the fan being housed within a cover adapted to pass cooling air backwards over the cylinders. A cam shaft is mounted vertically above the crankshaft, and the two are connected by gears mounted at the front of the crankcase. The rear end of the V-shaped region between the cylinders is open to provide for the escape of foreign matter, and the engine is balanced by locating the governor and the lubricant pump within the rear end of the crankcase.
