Abstract
Testing small-engine performance accurately can be challenging because many dynamometer systems are expensive, less flexible, and may not account for changing weather conditions that affect engine data. The goal of this work is to create a lower-cost and more adaptable inertia-based dynamometer for testing small engines while also considering weather conditions that can impact performance results. The system collects RPM data and uses rotational motion equations to calculate torque and horsepower. It uses an inertia wheel, a Hall effect sensor, a Raspberry Pi, and data logging software to measure speed over time. It also includes a weather correction factor to help produce more accurate and consistent results. Overall, this dynamometer combines mechanical design, electronics, programming, and engineering analysis into a practical system for small-engine testing.
