Four-stroke engine without crankshaft and valves

Abstract

The invention relates to a four-stroke engine free of a crank shaft and a valve. The engine comprises a base, a suction and exhaust valve, a base, a driving device group and a top seat. When a piston in each cylinder pushes the driving device group to enable a push rod connected with each piston to reciprocate vertically to push a cross rotating rocker arm connected with each push rod and enable the cross rotating rocker arm to push a rotating shaft piece to rotate to further achieve output of moving force of an engine mechanism with reciprocating motion converted into rotating motion, the cross rotating rocker arm also pushes a gear group of the driving device group to enable the gear group to drive the suction and exhaust valve on the base to rotate in a 360-degree in situ rotating motion mode to conduct suction and exhaust operation in the base. Due to the fact that the suction and exhaust valve rotates continuously and the special time sequence design is provided, the engine has the advantage that the crank shaft is not required, and a structure matched with the crank shaft to open and close the suction and exhaust valve frequently is not required.

Description

technical field [0001] The present invention relates to a four-stroke engine without crankshaft and steam valve; more specifically, it relates to a rotary engine mechanism that converts reciprocating motion into rotary motion for the output of engine mechanism action force with simplified structure, especially utilizing The rotary intake and exhaust valves can be rotated 360 degrees in the intake and exhaust slots in the base, and the special intake and exhaust sequence design is coordinated with the movement of the cross-shaped rotary rocker arm and the rotating shaft in the drive unit. , and through the design of the deceleration speed ratio between the gear set and the four-stroke cycle movement of the engine's intake, compression, explosion and exhaust, it is a unique, convenient and economical creation. Background technique [0002] With the advancement of science and technology and the development of industry, human beings have higher requirements for the engines used ...

AI Technical Summary

Problems solved by technology

[0003] The cycle process of the current engine is nothing more than two or four strokes (i.e. two strokes or four strokes); and the engine is powered by the crankshaft, that is to say, the crankshaft is the power output shaft of the whole engine; It is not a straight shaft from the beginning to the end. In order to provide the up and down linear motion of the piston to be converted into a rotary motion, the crankshaft must be designed as a zigzag shaft according to the number of pistons. Therefore, when the piston moves up and down in a straight line , often eccentricity occurs at the bend of the crankshaft, causing the piston to reciprocate eccentrically up and down, causing the piston to generate lateral force and rub against the cylinder, making the cylinder and the piston easily damaged under long-term friction

[0004] In addition, the well-known engine must be equipped with multiple groups of valve groups to provide cylinders for air intake, compression, explosion and exhaust operations. In terms of engine structure, it is relatively complicated.
