Motorcycle Engine

Case Western Reserve University

EMAE360 Design and Manufacturing II is the final course in the Mechanical Design sequence after EMAE160 and EMAE260, it is the Senior Capstone Design course for the Mechanical Engineering major.

As a team of 10, we were “responsible for the new engine design that will differentiate this
motorcycle from other competitors”. Some other requirements include:

• 2 or more cylinders, 4-stroke cycle

• Displacement 1500 to 1800cc

• Runs on standard gasoline

• Capable of 5000 rpm continuous service, idle at 800 rpm

We chose to construct an engine that will suit the three-wheeler market, as sales figures had been rising, and this layout allowed us some unique advantages. For example, we chose a displacement of 1800cc, as weight is less critical in the three-wheeled chassis, and this allowed us to generate more power.

As the CAD lead of our team, I was responsible for creating parts in SolidWorks, computing mechanical design elements (such as crankshaft balancing), and running FEA simulations to iteratively develop all load-bearing components.
