Application :

  • Universal range of application for examinations on engines and engine assemblies
  • Development of Petrol & Diesel engines for cars and commercial vehicles
  • Development and testing of engine assemblies, e.g. Piostons, Ignition systems, Sealing, Filters, Carburetor and Fuel Injection equipment, Exhaust gas ducting and catalysts
  • Quality Control
  • Development and Testing of Fules and Lubricants

Advantage :

  • Low Inertia Rotor
  • Internals of Gun Metal ensure Long life without corrosion and erosion
  • Bi-directional operation can be achieved by connecting the Prime-mover to be tested at either end
  • Low Initial and Running Costs
  • Lower level of expertise needed to operate these type of dynamometers
  • Stable Load Control

Principle :

The dynamometer is fed with water under pressure. When the torridal space is filled with water and the impeller is rotated by the prime - mover, a torridal flow is established outward in the impeller and inward in the stator, which acts as a STALLED TURBINE. Due to the change in momentum experienced by the water in passing from rotating impeller to the stator blade-ring, the torque impressed on the water by the impeller is transferred to the stator. This torque tries to revolve the cradled power absorption unit in the same direction of the impeller.The lever arm attached to the Stator Casing is linked to the Weigh - Bridge. It prevents the rotation of the power absorption unit and transmits the load to the load meter.
