Abstract

The utility model relates to a foursquare rotor engine, wherein, a power plate (3) of the rotor assembly with profile of smooth quadrangle power plate gearing face (S) is arranged in a quadrangle formed by four slip sheets (1), and meshes with the power gearing face (N) of the inner side of the slip sheet (1). A principal axis (4) is sleeved in the principal axis hole (K) of the power plate (3), two ends of which are sleeved with covers (5), and installed fixedly with a casing (2). The four slip sheets (1) forms four closed cavities in the casing (2). Each closed cavity has the process of sniff, compression, expansion and exhaust while the rotor assembly rotates a round. When starting, the principal axis (4) passes the power to slip sheet (1) through the power plate (3) so that the rotor assembly will rotate; after starting, the slip sheet (1) passes the power to the principal axis (4) through the power plate (3) to output power. The volume of the utility model is just twenty percent of that of the reciprocating engine. The utility model is with simple structure, well-balanced torque, high thermal efficiency, few pollution and little vibrating noise.

Description

A kind of engine with quadrangle rotor

Technical field
