Four-corner rotating piston engine

Abstract

The invention relates to a four-corner rotating piston engine. The four-corner rotating piston engine consists of a front cylinder cover, a cylinder, a rear cylinder cover, bearings, pistons, driving pistons, a main shaft, sealing elements, small bearings, driving pins, piston pins and spring pieces, wherein the position connection relation is that: the small bearings are arranged in the internal holes of the pistons and the driving pistons; a pair of pistons and a pair of driving pistons in which the small bearings are arranged are formed into a similar square part; the piston pins pass through the internal holes of the small bearings; the driving pistons are connected with the main shaft through the driving pins; the spring pieces are arranged in rectangular grooves of the pistons and the driving pistons respectively; the sealing elements are arranged on the spring pieces; the bearings are arranged in the internal holes of the front cylinder cover and the rear cylinder cover; the connected pistons, driving pistons, main shaft, sealing elements, small bearings, driving pins, piston pins and spring pieces form a rotor assembly to be placed in the cylinder; the front cylinder cover and the rear cylinder cover are sleeved at the front end and the rear end of the main shaft respectively; and the front cylinder cover and the rear cylinder cover are tightly connected with the cylinder by screws and nuts. The four-corner rotating piston engine has simple structure and scientific design and is a novel multi-purpose engine.

Description

technical field [0001] The invention relates to an engine, in particular to a four-corner rotary piston engine, which belongs to the technical field of internal combustion engines. Background technique [0002] The rotary engine in the usual sense refers to the triangular rotor engine, also called the Wankel engine, which was invented by the German Figas Wankel. On the basis of summarizing the previous research results, he solved some key problems. Due to technical problems, the first rotary engine was successfully developed. Rotary engines use triangular rotor rotational motion to control compression and discharge. [0003] Compared with the traditional reciprocating piston engine, this triangular rotor engine has greatly reduced vibration, and at the same time has higher power density. There are no linear reciprocating parts, no complicated intake and exhaust mechanisms, and reduced power loss. The structure is relatively simple and the weight is low. light. But the rea...

Problems solved by technology

However, the reason why this engine has not been developed in a large scale in the civilian field lies in several points: one is that the sealing of the engine is difficult and the wear is serious; Small, not easy to popularize and apply; Third, parts processing and maintenance are difficult

In the past few decades, Mazda Corporation of Japan has devoted itself to overcoming these difficulties, so that the problems of sealing and wear have been solved, but the inherent defects of rotary engines such as small torque and high speed are difficult to change. Due to the existence of the eccentric distance, there is still vibration. In order to balance the vibration, a balance weight must be set, which increases the weight of the engine itself, and the balance effect is not ideal, and vibration is inevitable.
