TBMC3 用于2.2千瓦的计算机控制测试台

The Computer Controlled Test Bench for Single-Cylinder Engines, 2.2 kW, "TBMC3", designed by EDIBON, is a teaching unit to test internal combustion engines of up to 2.2 kW.

The unit has an element to exert the braking torque, an asynchronous motor fed by a variable frequency drive. The shaft of the motor is connected to the shaft of the engine by means of an elastic coupling.

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: 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 "TBMC3" 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.
