Cylinder-cover-free engine with novel crankshaft-connecting-rod mechanism

Abstract

The invention provides a cylinder-cover-free engine with a novel crankshaft-connecting-rod mechanism. A power output unit of the engine comprises the novel crankshaft-connecting-rod mechanism, a power output gear and an air cylinder opposition device. The novel crankshaft-connecting-rod mechanism comprises a straight shaft, round wheels, connecting rods and fixed track plates. The two fixed track plates are driven by the air cylinder opposition device to do opening and closing reciprocating linear movement, and then the two connecting rods are driven to simultaneously conduct pushing drive and pulling drive on the round wheels at the two ends of the straight shaft correspondingly in the opposite directions, so that the two round wheels drive the straight shaft and the power output gear to rotate continuously. According to the engine, the novel crankshaft-connecting-rod mechanism which is simple in structure and reliable in operation is used for replacing conventional crankshaft-connecting-rod mechanisms with many defects, and the advanced air cylinder opposition device is adopted for driving; and an acting air cylinder of the air cylinder opposition device is not provided with a cylinder cover, automatic supercharging can be achieved while the air cylinder acts, the displacement can be flexibly changed, the fuel conversion efficiency is remarkably improved, and the two problems of lubrication and complete air exchange of conventional engines are effectively solved.

Description

technical field [0001] The invention relates to a reciprocating piston internal combustion engine, in particular to a cylinder headless engine with a novel crankshaft connecting rod mechanism and a cylinder opposing device. Background technique [0002] The traditional two-stroke diesel engine has the following disadvantages: [0003] (1) The cylinder head of a traditional engine has many accessories, takes up a lot of space, is complicated to install and debug, and has high noise and vibration during operation. [0004] (2) Adopt conventional crankshaft and connecting rod mechanism for transmission. The conventional crankshaft is one of the core components of the traditional engine, which has many insurmountable shortcomings, such as complex design and manufacture, difficult quality assurance, high requirements for manufacturing materials, limitations in increasing power and improving work efficiency, high manufacturing costs, installation And maintenance difficulties, sh...

AI Technical Summary

Problems solved by technology

The conventional crankshaft is one of the core components of the traditional engine, which has many insurmountable shortcomings, such as complex design and manufacture, difficult quality assurance, high requirements for manufacturing materials, limitations in increasing power and improving work efficiency, high manufacturing costs, installation and maintenance difficulties, short service life, etc.

[0005] (3) Insufficient combustion of fuel in the cylinder, serious exhaust pollution, high fuel consumption and low thermal efficiency

[0006] (4) The cylinder cannot establish an effective lubrication system, the heat dissipation is poor, the parts wear heavily, and it cannot work continuously
