一般說明

The Computer Controlled Test Bench for Four Cylinders Engines, 75 kW, "TBMC75", designed by EDIBON, is a teaching unit to test internal combustion engines of up to 75 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.
  • 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 "TBMC75" 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.

練習和指導練習

手册中包含的指导实践练习

  1. Determination of the characteristic curves of an internal combustion engine at different speed regimes:
  • Torque.
  • Power.
  • Specific consumption of fuel.
  1. Determination of the efficiency, fuel specific consumption and air-fuel ratio of an internal combustion engine.

Additional practical possibilities:

  1. Familiarization with four strokes petrol and diesel engines.
  2. Comparison of the characteristics of diesel oil and petrol engines.
  3. Study of cooling in alternative internal combustion engines.
  4. Pressure measurement in the combustion chamber of an engine (it requires the accessory TM75-01SP or TM75-02SP).
  5. Graphical representation of the combustion chamber pressure versus time and versus the position of the crankshaft (it requires the accessory TM75-01SP or TM75-02SP).
  6. Familiarization with the concept of supercharging for engines supercharged by a set of turbo and intercooler (it requires the TM75-02).
  7. Analysis of an internal combustion engine exhaust gases (it requires the TBMC-AGE accessory). Recommended for petrol engines.
  8. Calculation of the heat contained in the exhaust gases of an internal combustion engine (it requires the TBMC-CG).
  9. Study of the ignition of a petrol combustion engine (it requires the additional recommended element STRO).

Other possibilities to be done with this Unit:

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the TBMC75 unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the TBMC75 unit process.
  9. Several other exercises can be done and designed by the user.
