3 Agenda Project Background Problem Statement Use Scenarios Customer Requirements Engineering Requirements Draft of Project Plan Top 5 Concerns with the Project

4 Project Motivation Increases in oil prices Increasing environmental concerns Discovery of natural gas sources create the opportunity for an alternative fuel source

5 Pros and Cons of CNG (vs. Gasoline) Pros Cons Cheaper Cleaner Burning Energy Security in USA Less Energy Density Lack of Infrastructure Fracking Concerns

7 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

8 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

9 How will this CNG system work? Intake manifold Throttle body Fuel injector Air intake

10 Problem Statement: Current Design Dynamic Range of Flow of 100:1 Flow Rate Accuracy of ±1% No means of Flow Rate Control Not ready for use in an Automotive Environment

11 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 Prototype A Proportional-Integral-Derivative (PID) Actuator Control Algorithm to Increase Flow Rate Accuracy

12 Problem Statement: Project Deliverables Fully operational Prototype that can be Tested and Verified with Compressed Air Complete Technical Design Documentation Comprehensive System Operation Instruction Manual Technical Competitive Analysis Documentation of Failure Modes Demonstration at Imagine RIT

13 Problem Statement: Constraints Low Cost Small and Lightweight Design for Manufacturability Electrical/Mechanical Packaging for an Automotive Environment

14 Who are the Stakeholders? Alphacon LLC Dr. Roman Press MSD Team P15318 MSD Guide Edward Hanzlik Natural Gas and Oil Industries Automotive Industry Automobile Drivers RIT EPA
