Problems solved by technology

For gasoline internal combustion engines, although electronic injection technology is used to improve the degree of atomization, power performance and pollution discharge, etc., when this technology is used, the pre-compression gas in the steam chamber is a mixture of air and gasoline, while gasoline Flammable, resulting in reduced pre-pressure, low thermal efficiency of the engine, h

[0015] Example

[0016] The nozzle body (1) of the air-injection nozzle is provided with a middle through hole (2), the middle through hole (2) is a through hole, and the lower part of the needle valve hole is made, and the lower part of the valve hole communicates with the fuel injection nozzle. The nozzle is installed in the cylinder, the needle valve core (3) is installed in the middle through hole (2), and the lower end valve head of the needle valve core (3) and the lower needle valve hole of the middle through hole (2) cooperate to form a needle valve. The upper part of the needle valve core (3) and the middle through hole are in an interference type dynamic fit, and the lower part of the needle valve core (3) and the middle and lower part of the middle through hole (2) form an oil-passing gap type dynamic fit. When the needle valve core (3) moves up and the needle valve is opened, the lower part of the needle valve core (3) and the middle lower part of the middle through ho...

Abstract

A novel air-entraining oil nozzle for internal combustion engine is composed of conventional oil nozzle body with central through hole, needle valve is said central through hole and oil channel, and additional longitudinal air-storing hole with air-storing valve rod to form an air-storing valve. The valve hole at lower part of air-storing hole is communicated with the through hole at lower end of air-storing hole. its advantages include simple structure, high oil atomizing level, increasing power by 30-50%, reducing oil consumption by 20-30%, increasing compression ratio of 20 or more, and low cost.

Description

(1) Technical field [0001] The invention relates to an entrainment injection nozzle suitable for a fuel type internal combustion engine. (2) Background technology [0002] The overall performance of the internal combustion engine, such as power, fuel consumption, thermal efficiency, exhaust emissions, etc., is closely related to the degree of atomization of fuel in the cylinder. The degree of atomization is good, the fuel is fully burned, the compression ratio is high, the power performance is good, the fuel consumption is low, and the sewage discharge condition is good. On the contrary, the degree of atomization is low, the fuel combustion is not sufficient, the compression ratio is low, the power performance is poor, the fuel consumption is high, and the exhaust gas emission is poor. At present, diesel internal combustion engines mostly use high-pressure atomization and compression ignition. But because the atomization pressure used is as high as 200kg / cm 2 , so the tec...
