Abstract: “Measurement of output power from an engine is an important step in analysis of engine performance. Currently, dynamometers are used to measure the brake power of engines at varied loads. However, these devices are often expensive and sophisticated. Therefore there is a need to develop an extremely cost effective device for brake power measurement. In this work, a chassis dynamometer is designed and fabricated for testinga two wheeler vehicle. The drive axle weight is up to 800 kg. The dynamometer is primarily made out of mild steel and uses worn out car tires to function as rollers. The device is found to be extremely cost effective and reliable as compared to the existing dynamometers.”
