(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):
• 1TBMC8. Unit:
• Test bench for combustion engines up to 7.5 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.
  This motor also works as the engine starter.
  Transmission between the combustion engine and the brake through an elastic
  coupling.
  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:
• Unit: ATENG 12923
• Speed sensor to measure the speed (rpm) of the engine, range: 0 – 6000 rpm.
  Measurement of the electric motor braking torque.
• 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 meter to measure the fuel consumption, (depending on the purchased test engine),
• range: 2 – 40 ml/min.
• Two flow sensors to measure:
• Inlet air flow to the combustion engine, range: 0 – 400 m³/h.
• Exhaust gases outlet flow, range: 0 – 400 m³/h.
• 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 any of the protection panels is open.
  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.
• The representation of the characteristic curves of the combustion engines: torque or power 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.
