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. Generator load and 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.
