Abstract

The invention discloses a frequency conversion fuel injection nozzle for an engine, which comprises a pump body, the pump body is hollow to form an oil circulation channel inside, an oil injection hole is arranged at the front end of the pump body, and the oil injection hole The inner surface is wavy, so that the inner diameter of the oil injection hole changes periodically along the axial direction. The invention provides a frequency conversion fuel injector. The fuel injection hole at the front end of the fuel injector adopts the change of the inner diameter and the friction coefficient of the inner wall surface to increase the Reynolds number of the liquid, so that the internal movement of the liquid is violent, and the probability of molecular collision is increased. , to improve the fuel atomization effect. Therefore, the invention has the advantages of simple structure, high safety and high efficiency, good gasoline atomization effect and low pressure required by the fuel injection system.

Description

technical field

[0001] The invention relates to the technical field of automobile engine fuel injectors, in particular to a frequency-variable fuel injector for engines with variable inner diameters and variable friction coefficients of fuel injection holes. Background technique

[0002] With the development of the economy, energy shortage and environmental pollution have become worldwide problems. How to further improve the efficiency of internal combustion engines, save fuel, and reduce emissions has become one of the important directions for the development of internal combustion engine technology; today's automotive internal combustion engine technology mostly uses gasoline with low viscosity and fast evaporation. It is characterized by mixing and atomizing it with air to form a combustible mixture and spraying it into the cylinder to make it easier to burn.

[0003] Nowadays, the fuel injection holes of vehicle fuel injectors mostly adopt the form of constant inner diam...
