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. In the single cylinder two-stroke internal-combustion engine with the crank circular slide block, the unique double-acting piston special for the crank circular slide block mechanism is utilized, so that the piston can compress air and provide scavenging air flow when reciprocating and the integration of a compressor and the internal-combustion engine is realized; and the structural complexity is reduced obviously under the condition of the same scavenging effect.

Description

A crank circular slider single-cylinder two-stroke internal combustion engine technical field 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 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-m...

Problems solved by technology

Another problem is that when using a crank circular slider mechanism with a dynamic balance slider, the body is required to provide reciprocating guide rails for the dynamic balance slider. In many cases, the increased reciprocating guide rails 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,...
