Revolving internal-combustion engine

Abstract

The invention discloses a rotary internal combustion engine, which is characterized in that: an annular cylinder with a circular cross-section is composed of two identical annular cylinders with a semicircular cross-section, and two identical rotors are installed in the cylinder. The rotor is equipped with four pistons equipped with piston rings similar to those on the reciprocating machine. Two identical rotor shafts are respectively fixed vertically on the two rotors. Each of the two rotor shafts is equipped with a non-circular gear. The non-circular gear meshes with two identical eccentric gears with opposite installation directions installed on the same power output shaft. The rotor does work four times per rotation, which is equivalent to the amount of work done by the crankshaft of an eight-cylinder four-stroke internal combustion engine for one rotation. The rotary internal combustion engine does not have a valve mechanism, and can also be equipped with multiple spark plugs or fuel injectors and intake and exhaust ports. It can also increase the differential ratio by changing and adding non-circular gears and eccentric gear sets to improve work performance. . Multiple sets of cylinders can also be combined to provide greater output power.

Description

Technical field [0001] The invention relates to an internal combustion engine, in particular to a rotary internal combustion engine. Background technique [0002] The existing reciprocating two-stroke internal combustion engine consumes a lot of fuel, has low thermal efficiency, and has high pollution; the four-stroke internal combustion engine intake and exhaust valve system is complex in structure and consumes a lot of power. The cylinder body is out of round, which increases friction and increases the power loss and the difficulty of sealing. Also, due to the influence of the area of ​​the top of the combustion chamber, the intake and exhaust valves cannot be set too large, spark plugs or fuel injection The nozzle cannot be set too much, which greatly limits the further improvement of the performance of the internal combustion engine. At the same time, their complex crankshaft connecting rod mechanism and the reciprocating motion of the piston not only consume a lot of power,...

AI Technical Summary

Problems solved by technology

[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 much, 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)

In existing double rotation nonlinear transmission piston internal combustion engine (CN2313052Y) and wheel-step rotary piston engine (CN1564906A), between their two pairs of mutually nested pistons and its drum type (cylindrical or cone-shaped ) the sealing problem between the cylinders cannot be solved at all; the set output power of the two sets of non-circular gears of the double-rotation nonlinear transmission piston internal combustion engine is limited, and it cannot do work effectively at all. The principle of inertial mechanics, it is also impossible to do work effectively
