The four-stroke engine valve actuating mechanism generally comprises a valve group and a valve transmission group, and common valve actuating mechanisms can be divided into two categories, namely an overhead camshaft and a lower camshaft (including a middle camshaft) according to the arrangement of the camshafts on the engine.
The valve actuating mechanism with lower camshaft is located in the middle of crankcase and is driven with cylindrical timing gear, and the transmission from crankshaft to camshaft needs only one pair of timing gears and may have additional intermediate gear. For smooth meshing and noise reduction, the timing gear is mostly a helical gear. The gear transmission has the advantages of good transmission accuracy and reliability, but high noise. The valve train is mostly of an overhead valve type, and generally comprises a valve group, a valve transmission group and a valve driving group.
