Project Objective

Develop a Gaseous Mass Flow Rate Controller (GMFRC) that can deliver a precise amount of CNG for use in an internal combustion engine

Design a distribution plate for a means of mixing the CNG with air

Week 3 Problem Definition Review - 9/11/14

Definition: Gaseous Mass Flow Rate Controller

A device that can precisely regulate and control flow rates of various gases

Example: Regulator on a Gas Stove
