ATENG 12923 — Computer Controlled Test Bench for 75 kW Engines

(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4, 5 and 6.
• Optional items: 7, 8, 9 and 10.
• Let us describe first the main items (1 to 6):
• 1 ATENG 12923. Unit:
• Test bench for combustion engines up to 75 kW, with wheels to facilitate its
• mobility:
  Anodized aluminum frame and panels made of painted steel.
  Main metallic elements made of stainless steel.
  Diagram in the front panel with distribution of the elements similar to the real one.
  Mounting base with vibration dampening device to instal the testing engine.
  Transparent panels that allow to visualize the operation of the unit.
• Computer controlled electric eddy current brake to generate the load:
• Maximum power: 75 kW.
  Transmission between the combustion engine and the brake through a double
  Cardan joint.
  Acceleration of the combustion engine through the computer controlled fuel valve
  (acceleration/deceleration).
• 5 l capacity fuel tank: either for petrol or for diesel-oil (depending on the purchased
  test engine).
• Inlet air circuit:
  Air filter.
• Easy and quick connection hose of D : 40 m
  ext
• Exhaust gases circuit:
• Easy and quick connection hose of D : 40 m
  ext
• Instrumentation:
• Speed sensor to measure the speed (rpm) of the engine, range: 0 – 6000 rpm.
• Force sensor to measure the braking torque, range: 0 – 350 N·m. Unit: ATENG 12923
• Six “J” type temperature sensors at different points of the process:
  Inlet air temperature.
  Exhaust gases temperature.
  Fuel temperature.
  Engine oil temperature.
  Cooling system inlet and outlet water temperature.
  Flow sensor to measure the fuel consumption, either for petrol or diesel-oil (depending on the
• purchased test engine), range: 0 – 350 ml/min.
• Two flow sensors to measure:
• Inlet air flow to the combustion engine, range: 0 – 600 m³/h.
• Exhaust gases outlet flow, range: 0 – 600 m³/h.
• Pressure sensor for the oil of the combustion engine, range: 0 – 8 bar.
• To obtain the correct power of an engine it is necessary to measure ambient conditions with:
  “J” type temperature sensor.
• Pressure sensor, range: 0 – 1 bar.
• The unit includes all the safety measures required for a safe operation:
  Temperature limit.
  Limit switch to control if the brake and the engine are correctly connected.
  Limit switch to control if any of the protection panels is open.
  Safety pushbuttons.
  Safety individual hearing protectors to be used during the practical exercises are included.
• The Data Acquisition and Control Software of the “ATENG 12923” unit allows:
• The calculation of representative magnitudes: power of the combustion engine and specific
  consumption of fuel.
• The representation of the characteristic curves of the combustion engines: torque, power or specific
  consumption versus velocity of the combustion engine.
  The representation of the measured and calculated magnitudes curves, in signal versus signal
  charts. Free configuration of the axes of these charts.
  The representation in real time of all the measured and calculated magnitudes.
  The recording of the test measurements versus time and generation of a file compatible with
  spreadsheet applications.

Complete Technical Specifications (for main items)

• The complete unit includes as well:
  Advanced Real-Time SCADA.
  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Calibration exercises, which are included, teach the user how to calibrate a sensor and the
  importance of checking the accuracy of the sensors before taking measurements.
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user and remote control for technical support,
  are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
