Effect of Injection Hole Diameter on Operational Conditions of Common-Rail Fuel-Injection System for Portinjection Hydrogen-Fueled Engine

Effect of Injection Hole Diameter on Operational Conditions of Common-Rail Fuel-Injection System for Portinjection Hydrogen-Fueled Engine

Modeling of the hydrogen-fueled engine injection system is a very important tool that can be used to explain or predict the effect of advanced injection strategies on combustion and emissions. This work proposes a common-rail (CR) injection system for a four-stroke four-cylinder hydrogen-fueled eng...
