Pneumatic oil nozzle

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...

AI Technical Summary

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, high fuel consumption, and poor exhaust condition

The air-entrapped injection method developed abroad adopts the gas-oil pressure melting technology, although it can greatly improve the degree of atomization and improve the overall performance of the engine, but due to the complex structure, high manufacturing cost, and cumbersome use and maintenance, it affects the popularization and use
