Problems solved by technology

Ceramic material is a material with good heat insulation effect. If the parts of the cylinder liner, piston and other parts in direct contact with high-temperature gas are made of ceramic material, the actual thermal efficiency can be improved, but the low reliability caused by the brittleness of ceramic material becomes Technical obstacles in its application to engines

Embodiment Construction

[0041] Below in conjunction with embodiment the present invention is further described.

[0042] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown, a kind of two-cylinder two-stroke ring cylinder engine, it comprises:

[0043] Two oppositely arranged cylinders 1, the inner cavity of the cylinder 1 is made into a ring-shaped curved surface, and the ring-shaped curved surface refers to: a space curved surface formed by a circle in a plane rotating around an axis in the plane, the inner cavity of the cylinder 1 in the plane The circle is called the creation circle of the circular surface, the axis is called the creation axis, and the vertical distance from the center of the circle to the creation axis is called the creation radius; the two ends of the cylinder 1 have piston inlets,

[0044] A central shaft 8 is arranged between the two cylinders 1, and the axis of the central shaft coincides with the creation axis;

[0045] Two double-headed pistons 3 arranged in pairs...

Abstract

The invention discloses a double-cylinder two-stroke cylinder engine, belonging to the technical field of engines. The double-cylinder two-stroke cylinder engine comprises two gas cylinders which are oppositely arranged, two double-ended pistons, and a crankshaft, wherein inner cavities of the gas cylinders are manufactured into circular-ring-shaped curved surfaces; piston inlets are formed in the two ends of each gas cylinder; a central shaft is arranged between the two gas cylinders; each double-ended piston comprises a piston arm, wherein piston heads are fixed at the two ends of the piston arm; the piston arm is hinged on the central shaft; a sealed combustion chamber is formed between the two opposite piston heads of the gas cylinder; a connecting rod is hinged between the piston arm and the crank of the crankshaft; the crankshaft, the connecting rod, the piston arm and the central shaft form a crankshaft rocker rod mechanism capable of synchronously swinging the double-ended pistons, and enabling the piston heads to rotate back and forth around the central shaft between inner and outer stop points. The double-cylinder two-stroke cylinder engine can be used for effectively lowering the abrasion and impact of the piston and the cylinder sleeve, greatly improving the reliability of the ceramic material applied to the engine and improving the practical heating efficiency.

Description

technical field [0001] The invention relates to a two-stroke ring cylinder engine, which belongs to the technical field of engines. Background technique [0002] It is known in the field of engines that the Otto thermodynamic cycle includes two isovolumic heat absorption and heat release processes, and two adiabatic compression and expansion processes. Taking the compression ratio of 10 as an example, the theoretical thermal efficiency is about 60%. A gasoline engine is an internal combustion engine that approximately follows the Otto cycle, and its actual thermal efficiency is about 30%. For example, the theoretical thermal efficiency is about 58%. A diesel engine is an internal combustion engine that approximately follows the Diesel cycle, and its actual thermal efficiency is about 35%. [0003] It can be seen that whether it is a gasoline engine or a diesel engine, the actual thermal efficiency is much lower than the theoretical thermal efficiency. One of the main reaso...
