ィーゼル機関用燃料ガス噴射弁。In a fuel gas injection valve for a diesel engine that has a mushroom valve at the tip of a spindle that extends through a fuel gas reservoir filled with high-pressure fuel gas, an atomizer chip that has fuel gas injection is installed around the mushroom valve. A diesel engine characterized in that the valve opening period, especially when a small amount of injection is performed, can be easily controlled by using the pressure of the ejected fuel gas accumulated in the gap between the mushroom valve and the atomizer chip. Fuel gas injection valve.
