Thermodynamics > Internal combustion engines test beds





The test bed is intended for low speed, high torque industrial diesel engine.

The engine rests on its supports on a bed frame. The dynamometer can be either directly attached to the engine fly wheel or rests on its support and connected to the engine by a double universal joint with guard. Cooling of the engine and the dynamometer is by a cooling tower outside the engine room to minimize temperature rise. A thermo-static tank controls engine operating temperature. Engine throttle and dynamometer load control are by knobs.

Fuel tank and measuring instruments are in the engine room. Instrument panel with digital display and control buttons are in the control room.

Instruction manual is also included.
