External combustion type single-cylinder screw engine

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, ...

[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
