The Motorsport Engineering Program at CSU set out to design and build a floating liner engine to be used for the measurement of internal friction. A floating liner engine is one for which the cylinder liner is mounted in such a way that any rigid contacts are intermediated by force sensors. By equipping the engine this way it is possible to measure the forces acting on the cylinder liner due to the motion of the piston. The brake friction dynamometer was developed to test heat transfer and braking efficiency as well as perform brake bedding (initial transfer of brake pad material onto rotor). The system enables the testing and evaluation of calipers, friction materials and rotors, including rotor wear and friction modification treatments.
