Description of Publication: The purpose of this thesis is to discuss the determination of the mass flow rate of compressed natural gas through a Delphi Multec CNG Injector. Three methods are used to find the mass flow rates at various pressures. First, SolidWorks Flow Simulation is employed to calculate the mass flow rate with computational fluid dynamics. An analytical solution to the problem is also presented. Finally, experimental results from a previous year’s Capstone team are presented. Fuel flow curves are provided to compare the results from each methodology. The results from the SolidWorks Flow Simulation and analytical calculation agree at the extrema of the fuel rail pressure range tested, while the experimental results do not concur. Additionally, suggestions for future work necessary to tuning the CNG snowmobile to run on compressed natural gas are given.
