Problems solved by technology

[0002] The traditional multi-cylinder four-stroke fuel gas engine invented more than 100 years ago adopts a multi-cylinder design and requires a transmission. The manufacturing technology is complicated. Many core technologies are in the hands of a few countries, and the manufacturing cost is high; Small size, low air intake and low oxygen content before each ignition, insufficient fuel combustion, waste of energy, and high pollution emissions; the effect of cylinder air pressure on the crankshaft is point-type transmission, reducing output power; about 40% The kinetic energy of the air pressure is used to ignite the fuel under the cylinder pressure; if the ignition frequency is too high, the engine will overheat and need to be dissipated to dissipate energy.
As a result, the thermal efficiency of traditional engines is generally lower than 40%.
The low thermal efficiency itself reflects the major flaws in the principle of traditional fuel gas engines

Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0062] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0063] figure 1 , figure 2 Schematic illustration of engine workflow:

[0064] The external combustion box 9 is automatically supplied and ignited by constant pressure electric control, and the air pressure of 17 bar is generated in the combustion chamber 9 and is divided by two valves with different calibers. The small-diameter valve 13 splits 15-20% of the air pressure, which is discharged through the combustion chamber exhaust pipe 15, and acts on the V-shaped air compressor 18 to generate 6bar compressed air, which is stored in the 50L compressed air tank 20, and provides ...

Abstract

The invention discloses an external combustion type single-cylinder screw engine (hereinafter called the engine for short). The external combustion type single-cylinder screw engine comprises a single-cylinder screw air motor (hereinafter called the air motor for short), a 30-100 L external combustion tank body and fuel tank, a 100-150 L high-pressure air storage tank, a V-type air compressor anda 15-50 L compressed air tank; and the combustion tank body provides 15 bar of the air pressure for storage for the high-pressure air storage tank during combustion, and the high-pressure air storagetank provides working power with 15-9 bar of the air pressure for the air motor. The external combustion tank body adopts a constant-pressure electric control automatic feeding ignition device, meanwhile, the V-type air compressor provides compressed air not less than 2 bar for a combustion chamber, and the thermal efficiency of the engine can be improved to 70% or above.

Description

technical field [0001] The present invention relates to a new type of engine. More specifically, the present invention relates to an external combustion single cylinder screw engine. Background technique [0002] The traditional multi-cylinder four-stroke fuel gas engine invented more than 100 years ago adopts a multi-cylinder design and requires a transmission. The manufacturing technology is complicated. Many core technologies are in the hands of a few countries, and the manufacturing cost is high; Small size, less air intake and low oxygen content before each ignition, insufficient fuel combustion, waste of energy, and more pollution emissions; the effect of cylinder air pressure on the crankshaft is point-type transmission, reducing output power; about 40% The kinetic energy of the air pressure is used to ignite the fuel by the cylinder pressure; if the ignition frequency is too high, the engine will overheat and need to be dissipated to dissipate energy. As a result, ...
