TMHC Computer Controlled Test Bench for Hybrid Engine
The Computer Controlled Test Bench for Hybrid Engine (TMHC) is a teaching unit that allows to study and analyze the power source of a hybrid vehicle, consisting on a combination of an electrical motor and an internal combustion engine.
The Computer Controlled Test Bench for Hybrid Engine, "TMHC", is a teaching unit that allows to study and analyze the power source of a hybrid vehicle, consisting on a combination of an electrical motor and an internal combustion engine.
These two power sources are highly compatible, thus the hybrid vehicle makes the most of the advantages of each power source and, at the same time, it compensates for the disadvantages of the other.
The TMHC unit includes a dynamometer brake that introduces the load torque to the motor. The load torque is measured with the aid of the brake, which is coupled to the hybrid motor by the shaft. The torque is measured by the reaction generated on a load cell at the end of the arm (force sensor).
The speed of the hybrid motor is measured directly from the shaft of the motor with the aid of an optical sensor.
Besides, this unit includes a series of temperature, pressure, flow, speed and force sensors at different points of the unit.
