Problems solved by technology

However, the fundamental problem of fuel injection is how to improve the mixing degree of fuel and air, how to achieve high response speed of injection timing relationship and dynamic and precise adjustability of fuel injection quantity
So far, the fuel injection technology is fixed fuel injection technology, because the fuel injection will form a fan-shaped blank space (the so-called fan-shaped blank space is the space where the air and fuel are not mixed well or not mixed), thus affecting the mixing of fuel and air
Usually, in order to reduce and eliminate this fan-shaped blank space, high-atomization injection technology and air flow technology in the cylinder are often used, but these technologies are difficult to completely eliminate the fan-shaped blank space. Therefore, it is necessary to invent a new type of fuel injector that allows air and The fuel can be well mixed, which is conducive to the realization of homogeneous combustion and stratified combustion in the cylinder

Abstract

The invention discloses a fuel injector of an inner rotor for a motor. The fuel injector comprises a fuel injector shell and a valve body arranged in the fuel injector shell, wherein the valve body is provided with a rotating and driving structure of the valve body; and the valve body is controlled by a rotating and driving device of the valve body through the rotating and driving structure of the valve body to rotate along the central axis of the valve body. The fuel injector can realize homogeneity and fuel stratified injection in a cylinder, thereby improving the efficiency of the motor and environment conservation.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] The engine fuel injection device and its technology are very important to the efficiency and environmental protection of the engine. Therefore, there are many researches and products in this field. However, the fundamental problem of fuel injection is how to improve the mixing degree of fuel and air, how to realize the high response speed of the injection timing relationship and the dynamic and precise adjustability of the fuel injection quantity. So far, the fuel injection technology is fixed fuel injection technology, because the fuel injection will form a fan-shaped blank space (the so-called fan-shaped blank space is the space where the air and fuel are not mixed well or not mixed), thus affecting the mixing of fuel and air . Usually, in order to reduce and eliminate this fan-shaped blank space, high-atomization injection technology and air flow technology in the cylinde...
