Inportance of injector control valvle in the common rail injection system
With the increasingly stringent emission and fuel consumption regulations, the internal combustion engine continues to move towards the direction of cleanliness, high efficiency and energy saving. The strict emission regulations put forward higher requirements for the fuel supply system, and the fuel injection pressure can reach about 250MPa or even higher. High-pressure common rail has become the mainstream in the field of diesel engines due to its unique technical advantages, and the fuel injector, as the terminal effector connecting the upstream high-pressure common rail system and downstream fuel injection, is self-evident. The fuel injector control valve not only carries the functions of fuel lubrication, sealing and circulation, but also acts as a direct execution part of fuel injection, which determines the characteristics of fuel injection and spray, and then affects the subsequent fuel-gas mixing quality and emission characteristics. The control valve assembly is composed of a control valve and a control valve body. As the pressure of the high-pressure common rail injection continues to rise, the flow of high-pressure fuel in the nozzle (composed of needle valve assembly, pressure chamber, etc.) not only has a high Reynolds number The instantaneous turbulence of the jet is accompanied by the cavitation phenomenon caused by pulse contraction and fluid vortex motion, forming a complex gas-liquid two-phase flow, which in turn affects the fuel atomization quality at the nozzle outlet.
