Gas pulse timing vibration source fuel injector for engine

Abstract

The invention discloses a gas pulse timing vibration source fuel injector for an engine, which comprises a shell, an injection region and a fuel inlet interface. The shell is directly or indirectly communicated with the injection region; the shell is communicated with the fuel inlet interface; the fuel inlet interface is communicated with an oil pump through a vitta; the inside of the shell and / or the vitta are / is provided with a gas pulse timing vibration source; the gas pulse timing vibration source is communicated with a timing energy supplier through a passage; the gas pulse timing vibration source is directly or indirectly connected with the shell; and the gas pulse timing vibration source fuel injection is arranged in a cylinder and / or inside a gas inlet duct. The gas pulse timing vibration source fuel injector for the engine is not provided with a high-voltage fuel supplying system, has a simple structure, low manufacturing cost and rapid fuel injection response and further improves the working efficiency and low emission of the engine.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] Fuel injection technology is one of the most important technologies to improve engine efficiency and reduce engine emissions. In recent years, in the field of fuel injection technology for diesel engines and gasoline engines, although the fuel injection pressure has been continuously improved, and high-pressure common rail and solenoid valve control injection technologies have been widely used, most of the current fuel injectors are equipped with high-pressure oil supply systems, which have complex structures. Large volume, slow injection response and high manufacturing cost restrict the improvement of engine efficiency and environmental performance. Therefore, the applicant invented a fuel injector with simple structure, low manufacturing cost, small volume and fast injection response, thereby effectively improving the efficiency and low emission of the engine.
