A dynamometer, often shortened to “dyno,” measures force, torque, and power. For vehicle applications, it determines engine output by simulating real-world driving conditions. A chassis dynamometer measures power at the wheels, while an engine dynamometer measures output directly from the engine’s crankshaft. This measurement allows for precise tuning and performance assessment.
Understanding engine or wheel output is crucial for performance enthusiasts, mechanics, and engineers. It enables accurate diagnosis of engine problems, optimization of tuning modifications, and validation of performance gains. Historically, dynamometers have played a vital role in engine development, from early internal combustion engines to modern hybrid powertrains. This capability provides quantifiable data for performance benchmarking and analysis.
