DUAL FUEL INJECTION VALVE APPARATUS INCLUDING A HYBRID NOZZLE FOR DIESEL AND GAS ENGINES

摘要

The present invention relates to a dual fuel injection valve apparatus including a hybrid nozzle for diesel and gas engines, which may inject two types of fuels, one at a time, using a single fuel injection valve depending on the spring tension and the fuel pressure therein. According to the fuel injection valve apparatus of the present invention for injecting fuels into a cylinder of a diesel or gas engine, two types of fuels flowing into the valve may be injected one after the other, without being mixed with each other, through each nozzle hole of the valve, due to the different pressures of the two fuels and tensions of the needle springs.
