Problems solved by technology

The elastic internal combustion engine will overcome the deficiencies of traditional two-stroke and four-stroke engines such as less power stroke, large impact force, poor stability, high energy consumption, difficult realization of variable compression ratio, and difficulty in exhausting two-stroke engines. Significantly improve the power stroke of the engine, realize the smooth operation of the engine, reduce the impact force, reduce energy consumption, effectively discharge exhaust gas and enhance the engine power; moreover, the elastic internal combustion engine also uses a relatively simple structure and method to achieve variable compression ratio of the engine

Embodiment 1

[0034] Embodiment 1, with reference to Figure 1 ~ Figure 3 Cylinder 1 of novel elastic internal combustion engine is provided with top cover 2 and bottom cover 3, and the corresponding parts of the front and back sides of piston 4 and cylinder inner surface respectively constitute volume-variable combustion studio 10 and elastic studio 11. Elasticity working room is built-in with the elastic accumulator body 9 of storing certain pressure. The elastic energy storage body 9 of the present embodiment is compressed air. The bottom of the piston 4 body is a piston skirt 5 (between them is a piston head, an annular groove is provided, and a piston ring is placed in the annular groove), and the extension of the piston skirt 5 is an arc-shaped plate body 21 that is symmetrically spaced; at the same time, A symmetrical arc-shaped hole 8 is opened on the cylinder bottom cover 3, and the shape and size of the hole 8 and the piston skirt extension 21 are consistent, and a dynamic sealin...

Embodiment 2

[0044] Embodiment 2, with reference to Figure 4 , Figure 5 : Basically the same as Example 1, but with the following changes:

[0045] Use the piston rod 14 to carry out dynamic sealing connection with the central circular hole 15 on the cylinder bottom cover;

[0046] The elastic energy storage body 9 is liquid and compressed air (a film can be interposed between the two), the liquid is on the top, and the compressed air is on the bottom; the liquid accounts for about 1 / 8 to 1 / 3 of the entire cylinder space, and the compressed gas accounts for about 7 / 8 to about 2 / 3; under the pressure of the expansion force, with the displacement of the piston, the compressed gas can shrink into the energy storage adjustment mechanism, the expansion force disappears, and the compressed gas is pressed back into the elastic chamber.

Embodiment 3

[0047] Embodiment 3, with reference to Figure 6 , Figure 7 , Figure 8 : Basically the same as Example 1, but with the following changes:

[0048] The piston extension is an arc-shaped slide plate 17 (or other shapes such as a slide bar) symmetrically spaced. is an annular space around the outer diameter of the piston); at the same time, two or more arc-shaped mounting holes 16 on the cylinder bottom cover are also arranged on the outer ring of the cylinder, and the arc-shaped slide plate 17 (or slide rod, etc.) The position, shape and size of other shapes) correspond to each other, and the two form a movable connection. The arc-shaped slide plate can reciprocate in the chute on the cylinder wall. The elastic energy storage body 9 is a composite spring. No energy storage regulating mechanism is provided in this embodiment.

Abstract

The invention provides a two-stroke elastic internal combustion engine. A cylinder is provided with an air inlet system, an oil inlet system and an exhaust system; the cylinder is internally provided with a piston; a combustion chamber is formed by a space above a piston inside the cylinder; the invention is characterized in that the cylinder is provided with a top cover and a bottom cover at thesame time; the bottom cover of the cylinder is provided with a plurality of installation holes; the piston is provided with an extension body; the lower end of the extension body passes through the installation hole on the bottom cover of the cylinder and is connected with a connecting rod outside the bottom cover of the cylinder; the shape and the dimension of the installation hole on the bottomcover of the cylinder are consistent with those of the piston extension body; the installation hole on the bottom cover of the cylinder is movably connected or hermetically and movably connected withthe piston extension body; the reciprocating motion of the piston and the extension body drives motion mechanisms such as the connecting rod, etc., to motion; an elasticity working chamber is formed by a space between the bottom cover of the cylinder and the lower surface of the piston; the elasticity working chamber is internally provided with an elasticity accumulator which can store the pressure. The invention can obviously improve the proportion of the effective stroke of the engine, effectively exhausts the wasted gas and improves the exhaust cleanness, and improves the stability of the operation and the efficiency of the engine.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a two-stroke elastic internal combustion engine. Background technique [0002] The engine is an energy conversion mechanism that converts the heat energy generated by the combustion of the fuel mixture composed of fuel and air into mechanical energy. Engines are divided into internal combustion engines and external combustion engines. Generally speaking, the efficiency of internal combustion engines is higher than that of external combustion engines. Internal combustion engines mainly include reciprocating piston engines, rotary engines and turbine engines, among which reciprocating piston engines are the most widely used. Reciprocating piston engines are divided into four-stroke engines and two-stroke engines. According to the fuel they burn, they are mainly divided into gasoline engines and diesel engines. After certain modifications, they can also burn other fuels, such as nat...
