The camshaft of the diesel engine is arranged in a lower mode, a middle mode and an upper mode. The existing light high-speed diesel engine generally adopts an overhead valve camshaft form. Its advantages are high rotation speed of diesel engine, adapting to the match of passenger car, simple valve mechanism and less mechanical loss. The middle-mounted camshaft and the lower-mounted camshaft are difficult to improve the rotating speed of the engine, and overspeed causes the faults of valve bounce, large noise and the like, thereby affecting the performance and reliability of the diesel engine. However, at present, the design of an overhead valve camshaft diesel engine requires an optimum arrangement from the beginning. Generally, the mounting seat and the cylinder cover of the camshaft are integrally manufactured, and the high speed is generally realized by adopting full chain transmission or full gear transmission, so that the arrangement of a chain or a gear mechanism is convenient and leisurely; however, since the crankshaft and the camshaft are far apart from each other, if gear transmission is adopted, the mechanism becomes complicated and the transmission noise becomes large.
If the traditional V-shaped diesel engine adopts a middle-mounted cam shaft and a lower-mounted cam shaft, the rotating speed of the engine is difficult to increase, and a valve actuating mechanism is complex; if an overhead camshaft is adopted, because the distance between the crankshaft and the camshaft is long, all-gear transmission is often adopted, so that the transmission mechanism becomes complicated, and meanwhile, the noise of the engine is increased due to the all-gear transmission.
