Abstract

The invention discloses a double-crank mechanism engine, belonging to the technical field of engines. The double-crank mechanism engine comprises a gas cylinder and a piston capable of performing straight reciprocating motion in the gas cylinder, wherein two parallel crankshafts are arranged at the two sides of the gas cylinder; a connecting rod is hinged between corresponding crankshaft pins of the two crankshafts to form a double-crank mechanism; a connecting rod insertion slot and a slide block are arranged on a piston rod on the rear end of the piston, the connecting rod is inserted to the connecting rod insertion slot in a sliding manner, a guide block is fixed in the engine; a guide rail for sliding the slide block is formed on the guide block; the slide block is inserted to the guide rail; transmission gears are arranged on the end parts of the crankshafts; an output gear is engaged between the two transmission gears; and an output shaft is arranged on the output gear. The double-crank mechanism engine can be used for effectively lowering the abrasion and the impact of the piston and a cylinder sleeve, 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 high-efficiency engine and 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 reasons for this ...
