EDDY CURRENT DYNAMOMETER FOR HYDROGEN ENGINE

Power, speed and torque are the very important parameter when engine is about to be analysed. Thus while developing hydrogen engine test rig the measurement of power and torque by the engine is defined. To carry out this calculation we must possess a device which measures the power, speed and torque of the engine i.e. a dynamometer. This paper includes the different types of dynamometer and their basic information. The comparison has been done based on working principal, output energy form, material, user constraints and the design procedure of a dynamometer. The primary research includes the study of various dynamometers and the selection of suitable dynamometer which is capable for providing outputs in the form of electronic signals which are required in feedback loop to control the input parameter of the hydrogen engine. So by measuring the output parameters, input can be controlled significantly. Thus the eddy current dynamometer is meets the required specification.
