Two-stroke internal combustion engine and working method thereof

Abstract

The invention discloses a two-stroke internal combustion engine and a working method thereof. The structure of the internal combustion engine comprises a crankshaft, a crankshaft box, a piston, a cylinder, a connecting rod and an air booster; the crankshaft is positioned in the crankshaft box, the crankshaft is positioned in the cylinder, and the piston is connected with the crankshaft through theconnecting rod; an air inlet is formed in the top end of the cylinder, an air inlet valve is arranged in the air inlet, the air inlet is connected with the air booster through an air inlet pipeline;and an exhaust port is formed in the side wall of the cylinder, the position of the exhaust port on the side wall is positioned between a top dead center and a bottom dead center, and the exhaust portis provided with an exhaust valve. The two-stroke internal combustion engine has the beneficial effects that the exhaust is thorough, the working stroke of the piston is larger than the compression stroke, and the efficiency of the internal combustion engine can be improved; and a cycle has only two strokes, and the power performance is good.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a two-stroke internal combustion engine and its working method. Background technique [0002] Higher power and higher efficiency have always been the direction of development and advancement of internal combustion engines. The traditional four-stroke internal combustion engine only does one work in two revolutions in one working cycle, which makes its power performance not very good. Compared with the four-stroke internal combustion engine, the power performance of the traditional two-stroke internal combustion engine is much better, but the exhaust gas of the traditional two-stroke internal combustion engine is not sufficient, and the unburned fuel is easily discharged from the exhaust port, resulting in the disadvantage of low efficiency. [0003] In order to cope with the increasingly severe environmental and energy problems, gasoline-electric hybrid power is a main...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a two-stroke internal combustion engine and its working method, which overcomes the shortcomings of insufficient exhaust gas exhaust of traditional two-stroke internal combustion engines, and the working stroke is greater than the compression stroke, which can effectively improve the efficiency of the internal combustion engine
