Abstract

Dynamometers, commonly referred to as dynos, are indispensable tools in validating automotive design concepts. This study focuses on testing engines with a displacement of 710cc or less, aligning with Formula Society of Automotive Engineers (FSAE) guidelines. The dynamometer design incorporates features like vibration reduction mechanisms and customized Arduino code to simulate one FSAE driving scenario: steady state driving. At the core of the dynamometer's operation is an eddy current brake powered by an AC source, employing Faraday's Law of electromagnetic induction to mimic dynamic resistance. Engine power is transmitted to the eddy current brake through a meticulously analyzed shaft, engineered to withstand torques of up to 65 Nm. The dynamometer's design emphasizes modularity, facilitated by adjustable front and rear mounts securely fastened with bolts and nuts. The frame is built to house electrical components, and adjustable mounting regions to connect the eddy current brake with the engine via the designed shaft. Once operational, our engine dynamometer will serve as a valuable tool for monitoring various engine parameters, including power output, torque, engine speed, fuel consumption, exhaust gas composition, as well as coolant and oil temperatures. This comprehensive data collection will significantly aid in evaluating engine performance under various FSAE driving conditions.
