Air-fuel Mixing and Fuel Flow Velocity Modeling of Multi Holes Injector Nozzle on CNG Marine Engine

This research deals with the computational modeling assessment of a new multi holes injector nozzle for a sequential port injection CNG engine. The objective of this paper was to investigate the characteristics of a new multi holes injector nozzle on CNG engine. The methodology of this research is using computational modeling of the fuel flow of the new injector nozzle was made using Cosmos FloWok. The investigation is focused in the characteristics of the fuel-air mixing and flow velocity on CNG engine effect using the new multi holes injector nozzle. The result of the computational modeling of the fuel flow of the new injector nozzle increased the spray distribution, fuel-air mixing and fuel flow velocity.
