Chassis dynos test the complete vehicle, measures power and can also be a powerful tool for diagnosis. Measurements are done on the wheel and the power the wheel deliver is first measurement, transmission losses between engine and wheel can also be measured, and so the engine power. They allow to make tests inside the shop avoiding road tests which are dangerous and give much more information. We make several dyno alternatives: inertial, with hydraulic or electric brakes and combined; for cars, trucks, buses, motorcycles and kart.
BFH is the suitable dyno to make vehicle diagnosis, for cars, trucks ore ven big buses. A hydraulic brake is coupled to the rolls and allow to simulate any road situation for long periods of time and can measure power, check ECU fails or measure exhaust gases.
