Two-stroke internal combustion engine adopting dust fuel

Abstract

The invention belongs to the field of internal combustion engines, and particularly relates to a two-stroke internal combustion engine adopting dust fuel. The two-stroke internal combustion engine comprises an air cylinder body, a piston and a crank and connecting rod mechanism, wherein the air cylinder body, the piston and the crank and connecting rod mechanism are installed on an engine body, the air cylinder body comprises end covers and a cylinder wall, the piston is arranged in the air cylinder body, combustion chambers are defined by the piston, the end covers and the cylinder wall, and a spark plug, a powder nozzle and an air valve are arranged on the combustion chambers in a matched mode. The air valve is opened and closed through an air distribution mechanism, and the two-stroke internal combustion engine is characterized in that the left end cover and the right end cover are arranged at the two ends of the air cylinder body correspondingly, the left combustion chamber is defined by the piston, the left end cover and the cylinder wall, the right combustion chamber is defined by the piston, the right end cover and the cylinder wall, and a piston rod is fixedly connected to the center of the piston. The piston rod passes through the center of the left end cover and / or the right end cover and is connected with the crank and connecting rod mechanism located outside the air cylinder body, and the crank and connecting rod mechanism converts direct movement of the piston into rotation to output the power outwards. According to the two-stroke internal combustion engine, two-time combustion explosion exists in two strokes and acts on the piston, and compared with an internal combustion engine with an existing structure, the two-stroke internal combustion engine has the advantages that the efficiency is higher, and the output power is higher.

Description

technical field [0001] The invention belongs to the field of internal combustion engines, in particular to a two-stroke internal combustion engine using dust fuel. Background technique [0002] Existing reciprocating internal combustion engines perform work by burning liquid fuels such as gasoline and diesel oil or gaseous fuels such as natural gas. These fuels cannot be regenerated. With the sharp increase in mining and usage, the resources are becoming increasingly scarce and will eventually be exhausted. Chinese patent CN200410022274.7 Reciprocating internal combustion engine using dust fuel provides an internal combustion engine using dust. The internal combustion engine mixes high-temperature dust and air into the combustion chamber for deflagration, pushes the piston to do work, and converts linear motion into rotational motion for external output. Rotary power, the invention can use renewable organic or inorganic refined dust fuels, such as charcoal powder, as fuel. ...

AI Technical Summary

Problems solved by technology

However, this internal combustion engine is based on the existing cylinder mechanism, and there is no power output for at least half of the time in the reciprocating motion of the piston. This internal combustion engine has the problem of low output efficiency.
