The unit provides basic means for testing a single cylinder internal combustion engine.
The engine is connected to the mechanical brake absorber dynamometer on the test bed by a direct coupling with a safety guard. The engine throttle and dynamometer load are manually controlled. Instruments are provided for measurement of the absorber torque, speed, fuel flow rate, air flow rate, and temperatures. Fuel tank and measuring instruments are on a separate stand.
The test bed requires outside water supply for cooling.
- Torque vs engine speed at various throttle setting.
- Engine brake horsepower and efficiency vs speed
- Specific fuel consumption
- Air/fuel ratio
