The Design

A team of 10 senior engineering students including myself were tasked with designing a 1500-1800cc engine for a touring motorcycle in a Mechanical Design course.

I acted as technical team lead and led the requirements generation, managed the CAD assembly. The above renders represent the final state of the design after 1 semester of work, culminating in a Detail Design Review presentation.

Technical Responsibilities

I was responsible for constructing the engine cooling analytical model and reflecting that in the final CAD.

I first used a MATLAB code to determine the heat flux experienced by the engine over the crank angle.

Next, a thermal resistance model was iterated across the coolant path using a MATLAB script. A coolant passage width of 0.25″ was found to result in an allowable 71C wall external wall temperature.

The figure above shows the final coolant path in the CAD model.
