A circulating piston internal combustion engine with variable compression ratio and increased capacity

Abstract

The invention discloses a variable compression ratio capacity-increasing cycle piston type internal combustion engine. Air in a compressed air cylinder is compressed by a compressed air cylinder piston mechanism and is discharged to an acting air cylinder in good time; the air is detonated in the acting air cylinder; an acting air cylinder piston mechanism is driven to supply a driving force and drive an inertia flywheel to rotate; the next compression of air in the compressed air cylinder is driven by the rotation inertia of the inertia flywheel; collaborative close control mechanisms are arranged on the exteriors of valve which are used for communicating with outside air and are arranged on the compressed air cylinder, the acting air cylinder and an air cylinder connecting pipe. Compared with the prior art, the variable compression ratio capacity-increasing cycle piston type internal combustion engine has the advantages that the heat efficiency of the traditional piston type internal combustion engine is increased, the acting power is increased, and fuel is saved.

Description

technical field [0001] The invention relates to a piston internal combustion engine, in particular to a piston internal combustion engine with variable compression ratio and capacity increasing cycle. Background technique [0002] At present, most of the internal combustion engines used in automobiles or similar fields are piston internal combustion engines, and the common ones are four-stroke internal combustion engines. The defect of low efficiency in the use of mechanical energy. Otto cycle engine, Diesel cycle engine, Miller cycle engine and Atkinson cycle engine, the first two have low thermal efficiency, the latter two have complex structure, heavy weight, and low power per liter; the heat conversion rate of general gasoline engines is 35 %, the heat conversion rate of diesel engine is about 45%, and the loss of mechanical energy in the transmission process of each mechanical structure also occupies a considerable proportion. [0003] In today's environment of energy...
