TBMC8 7.5 kW 电机测试台，通过计算机控制（PC）

The Computer Controlled Test Bench for Single-Cylinder Engines, 7.5 kW, "TBMC8", designed by EDIBON, is a teaching unit to test internal combustion engines of up to 7.5 kW.

The element of the unit that offers load torque is an eddy current electromagnetic brake. It is supplied by a variator that allows to control the supply voltage and to vary its torque characteristics. The brake is jointly coupled to the shaft of the combustion engine by a double Cardan joint that transfers torque and power.

The unit also includes:

• Instrumentation: there are several sensors that provide us measurements of the variables under study.
• Start system: the engine includes its own electric starter motor that facilitates its operation.
• Fuel supply system: it carries the required fuel to the internal combustion engine.
• Cooling system: it carries out the cooling required for the correct operation of the engine. A forced water current removes the heat generated in the engine and transfers it to the atmosphere with a radiator. In case of air-cooling, the refrigeration is obtained by the passing of ambient air through the fins of the engine.
• Air intake system: it allows the intake of fresh air in the engine. It contains the oxygen required to generate the combustion.
• System to remove the exhaust gases: it removes from the engine the substances generated during the combustion and reduces the noise inherent to the gases flow.

The engine test bench "TBMC8" allows to study combustion engines, obtaining their characteristic curves by setting the accelerator of the engine to a specific position and varying the braking torque. Thus, different points of the torque or power versus velocity characteristic curve are obtained. Such curve will be at full load if the accelerator is at its maximum position.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
