MT 503G SINGLE CYLINDER ENGINE TEST BED, Electric Generator Absorber

This is a small test bed for a small gasoline or diesel engine.

The engine is connected by V-belt with a safety guard to an electric generator absorber dynamometer on the test bed. Heat from the generator is dissipated by heaters with a fan. Control of the generator load is by manual switches and of the engine throttle are manually controlled.

A fuel tank and air box are on a stand next to the engine.

Instruments are provided for measurement of engine speed, generator speed and torque, fuel flow rate, air flow rate, and temperatures.

Instruction manual is also included.

  • Torque vs engine speed at various throttle setting.
  • Engine brake horsepower and efficiency vs. speed.
  • Specific fuel consumption
  • Air/fuel ratio
  • Volumetric efficiency
Generator capacity 7 kW.
Load Heaters and fan.
Engine Single cylinder gasoline engine, up to 5 kW or as required.
Measuring instruments
