Agenda  Project Background  Problem Statement  Use Scenarios  Customer Requirements  Engineering Requirements  Draft of Project Plan  Top 5 Concerns with the Project Week 3 Problem Definition Review - 9/11/14

Project Motivation  Increases in oil prices  Increasing environmental concerns  Discovery of natural gas sources create the opportunity for an alternative fuel source Week 3 Problem Definition Review - 9/11/14

Pros and Cons of CNG (vs. Gasoline) Pros Cons  Less Energy Density  Cheaper  Lack of Infrastructure  Cleaner Burning  Fracking Concerns  Energy Security in USA Week 3 Problem Definition Review - 9/11/14

Week 3 Problem Definition Review - 9/11/14

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? Intake manifold Throttle body Fuel injector Air intake Week 3 Problem Definition Review - 9/11/14

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 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 Prototype  A Proportional-Integral-Derivative (PID) Actuator Control Algorithm to Increase Flow Rate Accuracy Week 3 Problem Definition Review - 9/11/14

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 Week 3 Problem Definition Review - 9/11/14

Problem Statement: Constraints  Low Cost  Small and Lightweight  Design for Manufacturability  Electrical/Mechanical Packaging for an Automotive Environment Week 3 Problem Definition Review - 9/11/14

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 Week 3 Problem Definition Review - 9/11/14
