Reverse hedging internal combustion engine

Abstract

The invention relates to a reverse hedging internal combustion engine, which has a novel structure, saves fuels and has the thermal efficiency which is improved by two times. The internal combustion engine comprises an internal combustion engine cylinder sleeve, wherein an air inlet is formed in the middle of the internal combustion engine cylinder sleeve; an air inflow fire striking device for controlling air inflow and fire striking is arranged at the air inlet of the internal combustion engine cylinder sleeve; a left piston and a left crank mechanism are arranged on the left side of the air inlet of the internal combustion engine cylinder sleeve from inside to outside; a right piston and a right crank mechanism are arranged on the right side of the air inlet of the internal combustion engine cylinder sleeve from inside to outside; the left piston and the left crank mechanism as well as the right piston and the right crank mechanism are symmetrically arranged on the two sides of theair inlet; the left crank mechanism and the right crank mechanism are connected to the same output shaft through a transmission mechanism for output; and internal time among air inlet stroke, compression stroke, fire striking stroke and exhaust stroke which are controlled by the air inflow fire striking device is synchronous with the back-and-forth movement interval time of the left piston and the back-and-forth movement interval time of the right piston. The internal combustion engine has the characteristics of improving the thermal efficiency by two times, along with a novel structure.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a reverse hedging internal combustion engine with novel structure, fuel saving and double thermal efficiency. Background technique [0002] Since the piston internal combustion engine came out in the 1860s, it has been a relatively complete machine through continuous improvement and development. It has high thermal efficiency, wide range of power and speed, convenient matching and good maneuverability, so it has been widely used. Various types of automobiles, tractors, agricultural machinery, engineering machinery, small mobile power stations and chariots all over the world are powered by internal combustion engines. Merchant ships at sea, inland watercraft and conventional ships, and some small aircraft are also propelled by internal combustion engines. The number of internal combustion engines in the world ranks first among power machinery, and it occupies...

AI Technical Summary

Problems solved by technology

Most of the existing internal combustion engines have only one piston. When the oil and gas burn, only nearly half of the explosion thrust acts on the piston, while nearly the other half of the explosion thrust acts on the cylinder block. The explosive force of combustion is not fully utilized, reducing the Piston working efficiency; And, the internal combustion engine of prior art also has the following deficiencies:

[0003] First, due to the single-cylinder, single-crankshaft, and single-piston design, the stroke of the piston is short, the amount of air inhaled is insufficient, the oxygen required for compression combustion is insufficient, the combustion is insufficient, and the explosive force is not fully utilized;

[0004] Second, the valve clapper is used to control the air distribution method, which has poor sealing performance, is prone to failure, and has loud noises, and uses the spring back pressure valve clapper sealing control principle method, which requires its own mechanical power to push the valve spring when the valve is exchanged. To realize the opening and switching of the valve valve, it consumes a lot of power, and the use of the valve clapper to control the air distribution method requires complex configurations such as timing gears, camshafts or synchronous joints. The cooperation between the valve clapper and the piston requires high accuracy. If one of the accessories If there is a fault, the valve racket and the piston will collide and be damaged, and cause secondary and more serious damage;

[0005] Third, the connection between the cylinder body and the cylinder head is at the highest temperature in the combustion chamber and the high explosive force, which often damages the cylinder head gasket, causing water, oil, air and other failures;

[0006] Fourth, the manufacturing cost is high, the service life is short, and the maintenance is complicated;

[0007] Fifth, the mechanical energy of combustion conversion is not fully utilized, resulting in high fuel consumption
