Abstract

The invention discloses a cam shaft with oil distribution timing, and relates to an engine. According to the cam shaft, an oil distribution cam is arranged on the basis of an original cam, formed by connecting a base circle, an oil stopping cam track circle and an oil releasing cam track circle smoothly, connected with an air inlet cam and an air exhaust cam in series and rotate coaxially with the air inlet cam and the air exhaust cam. In the use process, the cam shaft can be arranged on different portions to control other hydraulic components. According to the cam shaft with oil distribution timing, when the engine runs, the other hydraulic components are controlled to provide or maintain or release high pressure oil at a certain crank angle, the oil distribution function is achieved, the structure is simple, the cam shaft can be applied by changing a cylinder head of the engine slightly, and other functions of the cam shaft are steel effective.

Description

technical field [0001] The invention relates to the field of engines, in particular to a camshaft. Background technique [0002] The camshaft is driven by the crankshaft of the engine and maintains a fixed transmission relationship with the crankshaft. When the engine is running, the camshaft drives the valve to open and close to achieve a certain valve timing. [0003] The existing engine camshaft is mainly provided with an intake cam and an exhaust cam, which drive the intake valve and the exhaust valve respectively. In addition to intake cams and exhaust cams, there are no other forms of cams on the existing engine camshafts, so it is difficult to meet the needs of special occasion functions. Contents of the invention [0004] In order to increase the function of the existing camshaft, the invention provides a camshaft with oil distribution timing which is simple in structure, easy to realize and compatible with the prior art. [0005] In order to achieve the above o...
