Abstract
In an internal combustion engine, a lubricated camshaft assembly is in a cam chamber formed between a cylinder head and a cylinder head cover. The cylinder head includes outer bolt-receiving holes in which selected head bolts are inserted, and which are outside of the cam chamber. An oil discharge passage in the cylinder head has an inlet opened into the cam chamber, and an outlet opened into an outer bolt-receiving hole. The inlet of the oil discharge passage is disposed on one lateral side of the cam chamber. An opening part of a timing chamber is on the other lateral side of the cam chamber. An endless loop timing chain or belt is disposed inside of the timing cover, for transmitting the power of a crankshaft to the camshaft. A vehicle, which may be a four-wheeled all-terrain vehicle, may incorporate the engine and cylinder head as described.
