Single cylinder two-stroke internal-combustion engine with crank circular slide block

Abstract

The invention discloses a single cylinder two-stroke internal-combustion engine with a crank circular slide block. A crank circular slide block mechanism of the internal-combustion engine comprises a crank shaft, a circular slide block and a piston corresponding to the circular slide block; the piston is a double-acting piston of which both ends are provided with a working head respectively, and the piston is arranged in an air cylinder; the first working head at one end of the piston is used as a piston head of the internal-combustion engine, and a top surface of the first working head, an air cylinder inner wall and a cylinder cover arranged at one end of the air cylinder enclose to form a working cylinder; and the second working head is used as a scavenging piston head, and a top surface of the second working head, the air cylinder inner wall and a valve plate arranged at the other end of the air cylinder enclose to form a compressor air cylinder. The crank circular slide block mechanism also comprises a dynamic balance rotary block. Via an eccentric hole arranged on the dynamic balance rotary block, the dynamic balance rotary block sheathed on the same crank shaft together with the circular slide block is not directly connected with any reciprocating element and is fixed to the circular slide block as a mass member. The single cylinder two-stroke internal-combustion engine with a crank circular slide block is compact in structure and good in scavenging effect.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a single cylinder two-stroke internal combustion engine using a crank circular slider mechanism. Background technique [0002] Internal combustion engines are divided into four-stroke internal combustion engines and two-stroke internal combustion engines. Four-stroke internal combustion engines have a wide range of applications. A complete working process includes four strokes of intake, compression, power, and exhaust. The ignition works once every two weeks; unlike the four-stroke internal combustion engine, the two-stroke internal combustion engine only includes the first and second two strokes, and the crankshaft is ignited once every revolution, that is, after the same working cycle, the power stroke of the two-stroke internal combustion engine is four-stroke Twice that of an internal combustion engine. Above-mentioned feature adds that two-stroke internal-combustion engine...

Problems solved by technology

[0009] Another problem is that when using a crank circular slider mechanism with a dynamic balance slider, the body needs to provide a reciprocating guide rail for the dynamic balance slider. In many In some cases, the increased reciprocating guide rail will cause difficulty in machining the body, and weaken the strength or rigidity of the body, making it difficult to implement

Especially when using a two-stroke single-cylinder engine structure, the designer's main consideration is that this structure is relatively simple and light. If a dynamic balance slider is used to dynamically balance it, a set of reciprocating motion mechanisms must be added, and the corresponding in-body If the reciprocating track is set, the structure of this two-stroke single-cylinder engine will be very complicated, and the advantages of simplicity and lightness of the single-cylinder engine will be lost.
