Revolving internal-combustion engine

Abstract

The invention discloses a rotary internal combustion engine that includes a cylinder with circular section, containing two identical cylinder blocks with semi-circular sections. Two identical rotors are installed within the cylinder block and are provided with four pistons with piston rings similar to the reciprocation engine. Two identical rotor shafts are vertically fixed on the two rotors respectively. Two non-circular gears are installed on the two rotor shafts separately, which engage with two eccentric gears respectively attached to one output shaft respectively. The rotors work four times every revolution, equivalent to the work done by a 4 cylinder 4 stroke internal combustion engine for every two revolutions of the crankshaft. The engine may include multi spark plugs or injectors, multi intake ports and multi exhaust ports. The engine may also combine multi cylinder blocks to provide larger output power.

Description

technical field [0001] The present invention relates to an internal combustion engine, in particular to a rotary internal combustion engine. Background technique [0002] Existing reciprocating two-stroke internal combustion engines have high fuel consumption, low thermal efficiency, and large pollution; four-stroke internal combustion engine intake and exhaust valve systems have complex structures, high power consumption, and pistons, piston rings, and cylinders are always in a state of side friction, which is easy to use The cylinder block is out of round, which increases the friction and increases the power loss and the difficulty of sealing. Moreover, due to the influence of the area of ​​the cylinder head of the combustion chamber, the intake and exhaust valves cannot be set too large, and the spark plug or fuel injection The mouth also can not be arranged too much, thereby further improving the performance of the internal combustion engine is greatly restricted.

[0002] Existing reciprocating two-stroke internal combustion engines have high fuel consumption, low thermal efficiency, and large pollution; four-stroke internal combustion engine intake and exhaust valve systems have complex structures, high power consumption, and pistons, piston rings, and cylinders are always in a state of side friction, which is easy to use The cylinder block is out of round, which increases the friction and increases the power loss and the difficulty of sealing. Moreover, due to the influence of the area of ​​the cylinder head of the combustion chamber, the intake and exhaust valves cannot be set too large, and the spark plug or fuel injection The mouth can not be set too much, thus further improving the performance of the internal combustion engine is greatly restricted

At the same time, their complex crankshaft-connecting-rod mechanism and the reciprocating motion of the piston not only consume a large amount of power, but also increase the dynamic load of each force-bearing part and the wear of the bearing due to the inertia of its complex motion, and also increase the vibration of the engine, seriously affecting As the rotating speed increases, its mechanical loss power reaches 74%-80% (see the composition of the mechanical loss in the first section of the second chapter on page 38 of the book "Internal Combustion Engine Performance Improvement Technology")

Existing triangular rotor engine is difficult to achieve reciprocating effect because of its difficulty in processing, sealing plate (equivalent to the piston ring on the reciprocating machine) and its lubrication problems, oil consumption and exhaust emissions ("Special Engine Principles and Structure" book 3.3.2 Triangular Rotary Engine on page 171)

Existing instantaneous variable tolerance angular difference type rotor engine (application number 00123952. x publication number CN1349038A), the sealing problem between its two mutually forked rotors and between the body is difficult to solve, its two groups of non-circular gears and thumb wheels The mechanism's principle output power is limited or can't do work at all
