No-cylinder-cover double-combustion-chamber horizontal type four-stroke internal combustion engine

Abstract

The invention provides a no-cylinder-cover double-combustion-chamber horizontal type four-stroke internal combustion engine which comprises a cylinder body, special-shaped pistons, a crank-link mechanism and a valve seat air distributing system. An air cylinder is arranged inside the cylinder body. Two special-shaped piston heads are arranged inside the air cylinder in a butt joint mode. The special-shaped piston heads are connected with the crank-link mechanism and then connected with the valve seat air distributing system in a gear meshing mode so that the two special-shaped pistons move synchronously in the opposite direction in the air cylinder, and therefore the two special-shaped pistons, the crank-link mechanism and the valve seat air distributing system finish the four-stroke motion together. Moreover, four piston grooves and two piston top inclined faces are arranged in the positions of heat power banks of the special-shaped pistons to avoid opening and closing of a valve of the valve seat air distributing system. When the special-shaped pistons run to the top dead center of a compression stroke, two combustion chambers with the same size are formed in the positions of the gaps of the pistons top inclined faces and the valve. The no-cylinder-cover double-combustion-chamber horizontal type four-stroke internal combustion engine has the advantages of being high in compression ratio, high in rotating speed, stable in operation, large in torque power and long in service life, does not knock easily, saves energy, reduces emission, is green and protects environment.

Description

technical field [0001] The invention relates to a reciprocating piston internal combustion engine, in particular to a horizontal four-stroke internal combustion engine without a cylinder head and double combustion chambers. Background technique [0002] An internal combustion engine is a type of heat engine that converts the chemical energy of fuel into mechanical energy. The general implementation method is that fuel and air are mixed and burned to generate heat energy, and the gas expands when heated, and is converted into mechanical energy by mechanical devices to perform external work. Internal combustion engines have a very wide range of applications, and the engines of automobiles, ships, aircrafts, construction machinery, etc. are basically internal combustion engines. [0003] The most common type of internal combustion engine is of the reciprocating piston type. After the mixture of air and fuel in the cylinder is combusted, the high-pressure gas pushes the piston...
