Problems solved by technology

[0012] The problems to be solved by the present invention are: 1) no matter how much the throttle valve is in, a suitable actual air compression ratio can be guaranteed; 2) the power stroke does not use the crankshaft connecting rod mechanism to transmit force to avoid the power dead point; 3) reduce Unnecessary friction loss due to wasted piston sealing capacity during the exhaust and suction strokes

Embodiment Construction

[0031] in the attached figure 1 In , the entire mechanism is roughly classified into the following types, and the composition and working principle of each mechanism are described as follows:

[0032] 1) Main piston mechanism.

[0033] Mechanism is composed of: main piston (11), piston rod (12), articulated shaft (13), scale beam (14).

[0034] Connection relationship: the main piston (11) and the piston rod (12) are hinged or joint socket connected, the piston rod (12) is hinged through the hinge shaft (13) and the beam (14), and the two ends of the hinge shaft (13) are embedded on the casing in the chute. The top of the main piston (11) has an air vent.

[0035] Working principle: the articulated shaft (13) is constrained by the chute to keep linear motion, and the piston rod (12) also keeps linear motion without swinging. Because the scale beam (14) is hinged with the piston rod, the force applied to both ends of the scale beam (14) Can not form moment to add on the pis...

Abstract

The invention relates to a four-stroke engine (internal combustion engine); a flywheel has the motion similar to simple harmonic motion; the engine mainly comprises a reel mechanism, a crankshaft connecting rod mechanism, a main piston and a displacer piston; the main piston and the displacer piston form single-cylinder double pistons; the cross section of a reel is in a figure-eight shape; a steel rope passes through the middle of the figure-eight shape; the main piston is provided with a ventilation hole; the compression and power stroke displacer piston and the main piston move synchronously to seal the cylinder together; speed of the exhaust and suction stroke main piston is reduced and the displacer piston independently completes the exhaust and the suction action; the displacer piston is a light-weighted piston; and the engine solves the problems that actual air compression ratio of the opening of a small throttle is reduced, power dead points exist, and the sealing capability of the side wall of the displacer stroke piston is wasted.

Description

technical field [0001] The present invention relates to an internal combustion engine or engine, especially a reciprocating piston four-stroke engine. Background technique [0002] For a crankshaft-connecting-rod engine with a throttle valve, when the throttle valve is at a small opening, the actual intake air is smaller than the cylinder volume, and the actual air compression ratio is smaller than the rated compression ratio, which leads to low combustion efficiency and Organic pollutant emissions are high. [0003] The reciprocating piston engine of the traditional crankshaft-connecting rod mechanism has the problem of dead center of work. The bearing friction near the dead point of work is relatively large, the mechanical efficiency becomes low, and the heat generated by friction will lead to poor lubrication conditions of the bearing; crankshaft-connecting rod type The piston of the engine will be subjected to the side thrust of the connecting rod, which will increase t...
