Identify Customer Needs and Establish Specs

List of Needs & Metrics

The end goal of this project is for the customer to have the ability to test their engine in order to optimize its performance. The table below presents customer needs and associated metrics, or engineering specifications, that the team will attempt to design against in order to make this possible.

List of Metrics
# The driveline system: Rank Units Met?
1 Indicates and logs the horsepower of the test engine as a function of RPM. 10 hp, rpm Y
2 Indicates and logs the torque of the test engine as a function of RPM. 10 ft.lbf, rpm Y
3 Is easily disabled via a convenient "kill switch" in the operating room, as well as the monitoring room. 10 N/A Y
4 Uses 93 octane gasoline. 10 N/A Y
5 Comprises of a single engine test stand. 9 N/A Y
6 Allows user to pivot the engine 30 degrees forwards and backwards with a minimum increment of 5 degrees. 9 Degrees Y
