An absorption dynamometer is a device used to measure the power output of an engine or motor. It works by absorbing the energy produced by the engine and converting it into heat, which can then be measured. This allows engineers to determine the efficiency and performance of the engine under various conditions. These dynamometers are commonly used in automotive testing and research, providing valuable data for improving engine design and performance. By analyzing the results, engineers can make informed decisions about modifications and enhancements to engines, contributing to advancements in the automotive industry and related fields like mechanical engineering and automotive technology.
