Analysis of Piston Motion and Gear Ratio in Powertrain Systems

This report provides a detailed analysis of piston motion and gear ratio selection within the context of advanced powertrain engineering. The study investigates the parameters of piston motion, including travel distance, speed, and acceleration, using engine simulation devices and data analysis. The report examines the influence of the crankshaft on piston behavior and the impact of lubrication on engine performance. It delves into the piston assembly, force balances, and side thrust loads, as well as the four-stroke engine balance. The study also explores gear ratio selection, focusing on the Yamaha R6 engine, and the role of torque and horsepower in vehicle dynamics. The report includes calculations, analyses, and MATLAB simulations, providing insights into the relationship between engine components, performance, and the overall powertrain system. Furthermore, the report discusses the impact of rod-crank systems on engine performance and includes references to relevant literature.
