Oscillating bar type working cylinder

Abstract

Compressed air is directly input into the oscillating bar type working cylinder, when the compressed air enters the cylinder and reaches a certain volume, fuel oil is injected into the cylinder, then a spark plug is used for ignition, pressure in the cylinder is increased to push a piston to do work, after the piston does work, the pressure of gas in the cylinder is reduced, an air valve is opened, and waste gas is exhausted.

Description

Technical field:

[0001] Pneumatic engines, fuel engines, new energy Technical background:

[0002] The fuel efficiency of a fuel engine is relatively low. To effectively improve the fuel efficiency of a fuel engine, some adjustments need to be made to the structure of the engine so that the fuel efficiency of the engine can be improved. Summary of the invention:

[0003] (1) Compressed air is directly input into the cylinder. When the compressed air enters the cylinder and reaches a certain volume, fuel is sprayed into the cylinder, and then ignited by a spark plug, so that the pressure in the cylinder increases and the piston is pushed to do work. After the piston does work, the gas pressure in the cylinder decreases, the valve opens, and the exhaust gas is discharged.

[0004] (2) The piston works by pushing the rocker arm to rotate through the connecting rod. The rotation of the rocker arm drives the main shaft to rotate through the backstop to achieve power output.

[0005] The beneficial effects of this patent are: making the fuel fully burn and do work, improving the power output, using the swing rod to achieve power transmission, reducing the high-precision machining requirements of the crankshaft, saving machining costs, and overall improving the economic practicality of the fuel engine.

[0008] Figure 1 A check valve (2) is mounted on a main shaft (1), the inner ring of the check valve (2) is key-connected to the main shaft (1), a swing rod (3) is mounted on the outer ring of the check valve (2), a swing rod spring (4) is mounted on the swing rod (3), the top end of the swing rod (3) is rotatably connected to a connecting rod (5), the other end of the connecting rod (5) is rotatably connected to a piston (8), and a cylinder barrel upper end cover (6), a cylinder barrel (7), a fuel injector (10), a spark plug (11), a valve (12), and an intake solenoid valve (13) are mounted on a cylinder seat (9).

[0009] Figure 2 Middle: A through hole is opened in the center of the valve (12), a valve ejector pin (14) and a valve ejector pin spring (15) are installed in the through hole, the valve (12) is pressed on the valve ejector pin (14), and the valve ejector pin (14) is in contact with the valve spring (16).

[0010] Operation process of rocker type working cylinder:

[0011] exist Figure 1 Middle: When the working cylinder is in a non-working state, the rocker spring (4) acts on the rocker (3), and the rocker (3) exerts force on the piston (8) through the connecting rod (5). The piston (8) is closely attached to the cylinder seat (9), so that the valve (12) closes the exhaust hole on the cylinder seat (9).

[0012] During operation, the air intake solenoid valve (13) is energized, and compressed air enters the cylinder (7) to push the piston (8) to do work. When the piston (8) moves to a certain position, the air intake solenoid valve (13) stops intake, the fuel injection nozzle (10) injects fuel, and the spark plug (11) is energized to ignite, the piston (8) moves and continues to do work, the swing rod (3) rotates under the thrust, and due to the action of the backstop (2), the main shaft (1) is driven to rotate counterclockwise, and the output torque is used to do work.

[0013] When the piston (8) moves beyond the position of the side hole of the cylinder barrel (7), the pressure difference between the inner cavity of the cylinder barrel (7) and the outside world disappears, and the valve (12) is opened under the action of the valve spring (16), and the swing rod (3) pushes the piston (8) back to its original position under the action of the swing rod spring (4).

[0014] When the piston (8) returns to contact the valve ejector pin (14), the valve ejector pin (14) compresses the valve spring (16) and the valve ejector pin spring (14) at the same time, so that the valve (12) closes the exhaust hole on the cylinder seat (9) in advance, so that a buffer air cushion of a certain thickness is formed between the piston (8) and the cylinder seat (9), thereby reducing the impact of the piston (8) on the cylinder seat (9). When the piston (8) returns to the contact position with the cylinder seat (9), the rocker-type working cylinder completes one work.
