Engine Test Cell

Engine Test Cell

GARC provides three sophisticated engine test stands for carrying out emission testing as well as developmental testing in various automotive engines, tractor engines, gensets and Off road vehicle engines. Our test beds are capable of testing engines operating on Petrol, Diesel, Ethanol, Methanol, Blends, CNG, LPG, Bio- fuels and any alternate fuels.

Test Facility Description:

 

  • AC Engine Dynamometers (equipped with IGBT technology): ranges from 60 kW to 500 kW
  • Dedicated Combustion Air Handling Unit for emission testing purposes which provides conditioned air independent of the ambient conditions
    • Conditioned Humidity Range : 6-20 g/kg, with control accuracy +/-0.5 g/kg
    • Conditioned Temperature range : 15-35 °C, +/- 1 °C control accuracy
    • Pressure range : 900-1050 mbar(abs), +/-3 mbar accuracy
  • Unique Dynamic Engine Combustion Air Handling Unit with altitude simulation for controlled air input is available for developmental purposes
