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

SLIDE 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
