Tumbler and piston type engine

Abstract

The invention discloses a tumbler and piston type engine. The engine comprises a cylindrical block, a transmission shaft, a fuel air cylinder group and a first linkage assembly; an accommodating cavity is formed in the cylindrical block; the transmission shaft is rotationally arranged on the axis of the cylindrical block; a first flat cam is fixed on the transmission shaft; a driving surface and a stressed surface which are centrosymmetric are arranged at each of two ends of the first flat cam; the fuel air cylinder group comprises a first fuel air cylinder, a second fuel air cylinder, a third fuel air cylinder, a fourth fuel air cylinder and piston-connecting rod assemblies arranged in the four fuel air cylinders; the first fuel air cylinder, the second fuel air cylinder, the third fuel air cylinder and the fourth fuel air cylinder are arranged sequentially; an air inlet and an air exhaust port are formed in two sides of the middle of the cylinder block part of each fuel air cylinder; the first linkage assembly comprises two strip-shaped tumblers and two V-shaped tumblers; and the reciprocating movement of pistons in the four fuel air cylinders drives the transmission shaft to rotate through extrusion of the driving surfaces and the stressed surfaces by the aid of the inner side surfaces of the two strip-shaped tumblers and the two V-shaped tumblers. The engine is high in energy conversion efficiency and simple and reasonable in structure.

Description

technical field [0001] The invention relates to the field of engines, in particular to a rotary arm piston engine. Background technique [0002] With the rapid development of science, technology and economy in the current society, human beings have an increasing demand for various motor vehicles and various power machinery, and the main energy sources are increasingly depleted, so people have higher requirements for engine performance. At present, engines used in mechanical power output sources such as vehicles and ships mainly include gasoline engines, diesel engines, rotary engines, and aviation jet engines. Gasoline engines and diesel engines use high-pressure gas to drive the linear reciprocating motion of the piston to drive the connecting rod and crankshaft to complete work, while the rotary engine uses a triangular rotor, which is eccentric along the cylinder wall in an oval cylinder through the cooperation of the gear in the center of the rotor and the shaft gear.

AI Technical Summary

Problems solved by technology

The cooling method and exhaust method adopted by gasoline engines and diesel engines cause a large amount of heat loss, and the thermal efficiency is relatively low, resulting in huge energy waste. The thermal efficiency of gasoline engines can only reach 30% at most, and the thermal efficiency of diesel engines does not exceed 45%. Rotary engines have lower thermal efficiency due to airtight design defects, and aeroengines require high fuel consumption and cost. Today, with the increasing awareness of environmental protection in the world and the depletion of oil resources, human beings have more desires to improve engine performance. Existing engines can no longer meet the needs of modern development
