Eccentric wheel rotary engine

Abstract

The invention relates to an eccentric rotational engine, which is formed by cylinder, eccentric wheel tangent with the cylinder, main baffle plate and auxiliary baffle plate on the cylinder wall and controlled by cam, a baffle plate controlled by spring, and a concave burning room on the cylinder wall, wherein the eccentric wheel rotates around the center of cylinder, to form one movable arc chamber with the inner chamber of cylinder; when working, the main baffle plate, the auxiliary baffle plate, and the baffle plate will separate the arc chamber into the gas inlet room, compress room, expansion room and discharge room which will periodically enlarge and reduce; the burning room is periodically connected to the compress room or expansion room, to compress and drive gas via eccentric wheel, and function the eccentric wheel at its back via burning gas. The invention has simple structure, better sealing effect, and high efficiency.

Description

technical field [0001] The present invention relates to an engine, in particular to a rotary engine. Background technique [0002] Reciprocating engines and rotary engines are two major types of engines. The ignition mode of reciprocating engine can be compression ignition type or ignition type, and can use a variety of fuels; but the efficiency of reciprocating engine is low, and the bottleneck restricting the development of reciprocating engine to high speed is the reciprocating speed of piston.

Problems solved by technology

The ignition mode of reciprocating engine can be compression ignition type or ignition type, and can use a variety of fuels; however, the efficiency of reciprocating engine is low, and the bottleneck restricting the development of reciprocating engine to high speed is the reciprocating speed of piston. Inertial force, the current average piston speed is up to 14.64 m / s

The existing rotary engine has a complex structure and higher efficiency than the reciprocating engine, but the three vertices of the triangular rotor are in line contact with the cylinder profile, the seal is not good, the gas leakage is large at low speed, and the performance is poor; and the rotary engine At present, ignition ignition is basically used, and the best fuel is gasoline. If diesel is used, complex ignition and control methods are required.

The existing two types of engines all use a gear mechanism, and the reciprocating engine also needs a crankshaft connecting rod mechanism to realize the rotation of the output shaft, and its structure is complicated.

In addition, both types of engines have overlapping phenomenon of intake and exhaust, so that the intake is insufficient, the exhaust is not clean, and the fuel combustion is not complete.
