Problems solved by technology
[0002] The camshaft is a part of the piston engine. Its function is to control the opening and closing of the valve. Due to the high speed of the engine, it needs to bear a large torque. Therefore, the design requires a lot of strength and support for the camshaft. High, because the law of valve movement is related to the power and operating characteristics of an engine, but the existing camshaft engines have high fuel consumption, low performance, and are inconvenient to use

Embodiment Construction
[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0013] see Figure 1-2 , the present invention provides a technical solution: a structure of an engine camshaft, including an intake camshaft 4, the left end of the intake camshaft 4 is provided with a pressure roller bearing 10, and the intake camshaft 9 can be lowered by the pressure roller bearing 10. The friction of the engine can reduce the noise of the engine, and the left end of the intake camshaft 4 is provided with a quenching vacuum pump groove 5, an...

The invention discloses a structure of an engine camshaft. The structure comprises an air inlet camshaft. A press roll bearing is arranged at the left end of the air inlet camshaft. A quenching vacuumpump groove is formed in the left end of the air inlet camshaft. A water pump transmission gear connector is arranged on the inner side of the right end of the air inlet camshaft. Hydraulic lash adjusters and hollow accommodating vent valves are uniformly arranged on the air inlet camshaft and distributed at intervals. Exhaust camshafts are uniformly arranged on the air inlet camshaft and locatedbetween the adjacent hollow accommodating vent valves. Friction of the air inlet camshaft can be reduced through the press roll bearing, and thus, noise of an engine can be reduced; the structure ofthe engine camshaft is simple in structure, easy and convenient to operate, and capable of reducing the friction of the camshaft and the noise of the engine; and a valve is quickly cooled, a higher temperature is borne, and thus, the stability of the engine is maintained.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a structure of an engine camshaft. Background technique [0002] The camshaft is a part of the piston engine. Its function is to control the opening and closing of the valve. Due to the high speed of the engine, it needs to bear a large torque. Therefore, the design requires a lot of strength and support for the camshaft. High, because the law of valve movement is related to the power and operating characteristics of an engine, but the existing camshaft engines have high fuel consumption, low performance, and are inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a structure of the engine camshaft, which is simple in structure and easy to operate, which can not only reduce the friction of the camshaft, but also reduce the noise of the engine, and quickly cool the val...
