    Abstract: A four-stroke engine comprises an oil tank (2), a crankshaft chamber (1), a distribution chamber (5), a rocker chamber (4), a combustion chamber (9), and a lubricating system. The oil tank (2) is communicated with the crankshaft chamber (1) through an oil supply channel (21). The crankshaft chamber (1) is communicated with the distribution chamber (5) through a first oil transmission channel (15) and a unidirectional valve (151) is disposed in the first oil transmission channel (15). The rocker chamber (4) is communicated with the crankshaft chamber (1) through at least one oil return channel (41), and a unidirectional valve (413) is disposed in each oil return channel (41). The distribution chamber (5) is communicated with the oil tank (2) and used for separating an oil-gas mixture into oil mist and fluid oil. The four-stroke engine further comprises a cam (7) and a transmission mechanism (8) connected between the cam (7) and a crankshaft of the crankshaft chamber (1) in a matched manner. The cam (7) is matched with a rocker (44) of the rocker chamber (4) and located above the combustion chamber (9). The four-stroke engine has a simple lubricating system, and is desirable in operation stability and low in noise.

    Abstract: A 4-stroke engine incorporating a mono-shaft multi-valve operating system, the multi-valve operating system incorporating a first cam follower assembly that is associated with an intake valve, a second cam follower assembly that is associated with an exhaust valve, and a cam follower channel assembly that is integrated into a crank web of the engine, the cam follower channel assembly including a base circle channel, a cam channel, and a cross-over channel. The cam follower channel assembly is configured to commonly interact with the two cam follower assemblies to operate the intake valve at a first instance, and the exhaust valve at a second instance, with both instances occurring while the crank web completes two rotations. When either of the two cam follower assemblies engages with a cam channel of the cam follower channel assembly, the cam follower channel assembly is configured to provide a camming operation to operate the respective valve. When either of the two cam follower engages a base circle channel of the cam follower channel assembly, the cam follower channel assembly is configured to prevent operation of the respective valve.
