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
Week 3 Problem Definition Review - 9/11/14
How will this CNG system work?
Air intake
Intake manifold Throttle
body
Fuel injector
Week 3 Problem Definition Review - 9/11/14
Problem Statement: Current Design
Dynamic Range of Flow of 100:1Flow Rate Accuracy of ±1%No means of Flow Rate ControlNot ready for use in an
Automotive Environment
Week 3 Problem Definition Review - 9/11/14
Problem Statement: Desired State
Increase the flow rate accuracy to ±0.5%A Distribution Plate for mixing CNG and Air Smaller and Lighter than Current PrototypeA Proportional-Integral-Derivative (PID)
Actuator Control Algorithm to Increase Flow Rate Accuracy
