The objective of
this tutorial is to demonstrate how design decisions affect a
product’s performance and its impact on the environment.
Specifically, you will examine how design attributes of the
automobile affect fuel economy and emissions, and finally, how these
associated emissions during a vehicle’s use phase impact local air
quality. This tutorial is broken down into five sections:
We begin with
an overview of vehicle design and discuss how factors such as
aerodynamic shapes, lightweight materials, and alternative
powertrains can contribute to fuel economy improvements.
Next, we will
discuss how emissions from line sources (i.e. automobiles) and point
sources (i.e. power plants and industrial sources) create air
pollution that has an adverse affect on human health and the
Then, you will
assume the role of an automotive engineer, and you will be asked to
design a car that will compose the entire Ann Arbor vehicle fleet.
You will be given the opportunity to choose a vehicle shape, mass,
and powertrain to obtain fuel economy and emission values specific
to your configuration.
Air Quality Model
With your new
vehicle design, you will be given the opportunity to see how it
impacts the air quality within the central campus of the University
of Michigan. You will be introduced to statistical dispersion
modeling and utilize the CALINE 4 model to predict pollutant
concentration at various locations throughout campus.
concludes with some exercise where you can apply these topics to
quantitatively address real life issues pertaining to automotive
design and air quality in the environment.
