The invention discloses a micro-nanometer fuel injector for an engine, which comprises a shell, a fuel inlet interface and a vitta. The shell is provided with a micro-nanometer fuel injection region which consists of a plurality of micron-level and / or nanometer-level fuel injection holes; the micro-nanometer fuel injection region is directly communicated with an inner cavity of the shell; the inner cavity of the shell is communicated with a timing pulse fuel source through the fuel inlet interface and the vitta; and the micro-nanometer fuel injection region is arranged inside a cylinder and / or a gas inlet duct. The micro-nanometer fuel injector for the engine has no movement of a valve body, has simple structure, low manufacturing cost and rapid fuel injection response and further improves the working efficiency and the 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 have large volume and high manufacturing costs. , fuel injection response is slow and other disadvantages, especially the diesel injector needs to be equipped with oil return system, plunger couple and valve, the structure is complex, which restricts the improvement of engine efficiency and environmental protection performance. Therefore, the applicant invented a fuel injector with simple structure, low manufacturing cost, small volume and fast fuel i...
