Abstract

The invention discloses a four-stroke engine, and particularly relates to a valve-spring-free four-stroke engine. The valve-spring-free four-stroke engine comprises a crankshaft and a gear set. The crankshaft drives a gas distribution mechanism through the gear set, and the gas distribution mechanism comprises a rotor drive shaft, convex-concave wheel rotors and levers. The rotor drive shaft is arranged on the top face of a gas inlet and outlet cavity through a bearing frame, and the rotor drive shaft is provided with a drive gear. A rotor support and a lever support are arranged on the top face of the gas inlet and outlet cavity, the two convex-concave wheel rotors are arranged on the rotor support, and the two levers are arranged on the lever support. The convex-concave wheel rotors are provided with driven gears, cams and concave wheels, and the drive gear is engaged with the driven gears. Contactors are arranged on the two sides of each lever, and the contactors make contact with the cams and the concave wheels. One end of each lever is provided with a gas hanging frame, each gas hanging frame is connected with a valve in a hung manner, the other end of each lever is provided with a fine-adjusting nut, and the contactors are located on the end portions of the fine-adjusting nuts. The valve-spring-free four-stroke engine is reasonable in structure, a machine can run with the engine, gas leakage does not occur, high efficiency and energy saving are achieved, abrasion is reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to a four-stroke engine, in particular to a four-stroke engine without valve springs. Background technique [0002] Four-stroke engines all have valve train, and existing valve train is all provided with valve spring, and the effect of valve spring is mainly used for closing valve, but it also consumes extra energy simultaneously, and this must increase the fuel consumption of engine. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of extra energy consumed by the valve spring in the existing valve train, and to invent a four-stroke engine without valve spring. Because there is no valve spring, the engine has a good energy-saving effect and can Reduces wear and prolongs engine life. [0004] The object of the present invention is achieved in the following manner: the four-stroke engine without valve springs includes a cylinder body, a cylinder, a crankshaft, a piston, a connectin...
