Comparing Two Flywheel-Piston Linkages, Anthony Sanchez
Comparing Two Flywheel-Piston Linkages, Anthony Sanchez
Undergraduate Journal of Mathematical Modeling: One + Two
The main idea of this paper is to compare two different ways of linking a flywheel to a piston: the Scotch Yoke linkage and the Eccentric linkage. The Scotch Yoke linkage is a way to convert the linear motion of a piston into rotational motion by using a flywheel, or vice versa. The Eccentric mechanism, on the other hand, consists of a circular wheel that is fixed to a rotating axle that makes it rotate. We compare two methods by expressing both motions as functions of three variables (R, L and θ) and use these functions to …

A Simplified Model Of The Internal Combustion Engine, Christofer Neff
Undergraduate Journal of Mathematical Modeling: One + Two
This project further investigates a model of a simplified internal combustion engine considered by Kranc in 1977. Using Euler’s method for ordinary differential equations, we modeled the interaction between the engine’s flywheel and thermodynamic power cycle. Approximating with sufficiently small time intervals (0.001 seconds over a period of 12 seconds) reproduced Kranc’s results with the engine having an average angular velocity of 72/sec.
