Twin 250 for Formula Car

The Twin 250 For Formula car lives on at the University of Idaho through the Department of Mechanical Engineering and the Formula champions competition.The idea of the engine design positioned twin engine front and back. Two cylinders drive individual that rotate in opposite direction to canceling the moment.

Background
The Twin 250 for formula car project was started in 2012 by Dr. Edwin Odom, Professor of Mechanical Engineering. The project was started by previous students James Found and Dustin Clelland in 2015. Their goal of the project eliminated the Chain Drive and shrink the engine envelope and differential. Also, they made 500cc drivetrain out of 2*250cc engine for the FSAE.

Problem Statement
It is desired to have an engine-drivetrain combination consisting of two 250cc YZF motorbike engines. The engines mount in opposite orientation from one another in order to cancel moments caused by the reciprocal motion inside the running twin engine. The clutch output leads to a sequential manual transmission, then to a ring and pinion, through a limited slip differential, and finally to the wheels. The twin 250 project has many unknowns (linkage, rear differential alignment, strength analysis, weight distributions, etc.), but the end goal is to have a well-designed and analyzed plan for manufacturing, ordering, and installing the engine system in the formula car.

Project Goals

 * Maintain Transmission from previous projects.
 * Build the case for the entire engine and differential.
 * Order and analyzing the differential fits in twin 250 formula car.
 * Manufacture and install the engine system in the formula car.

Updating Previous Design
The previous design team build the engine, drivetrain and frame, but they haven't complete finish the transmission and don't have linkage connect each gear in transmission. Return to contents

 * ZhengsongXia: I’m am a student at the University of Idaho that is graduating with my Bachelor’s Degree in Mechanical Engineering in summer 2017. I'm from China. After four year studing at University of Idaho, I learnd a lot of knowledge from UI general course. Even though it was really hard to compelete my Engineering degree, but I really enjoy it. In the future, my future work will keep focus on the vehicle engine design or jet engine. Also, My another dream will travelling round the world
