ABSTRACT:
An internal combustion engine, the static parts of which are formed as die castings. The engine includes a plurality of cylinders each closed at its upper end by an individual cylinder head casting. Each cylinder head casting has at least two tubular extensions thereon forming air intake and exhaust passageways and at least two valve stem guides. All of the cylinder head castings have flat horizontally extending upper faces all lying in a single plane and on which a valve train casing casting is seated. A single camshaft is journalled in the valve train casing and arranged to operate the intake and exhaust valves of all of the cylinders. The upper end of the valve trains casing is closed by a cover having a breather opening communicating with the interior of the valve train casing and also having air intake openings communicating with the air intake passageway of each cylinder. A shroud is mounted over the cover to define an air chamber which communicates with atmosphere through an air filter.
