Four Cylinder Four Stroke Petrol Engine with Eddy Current Dynamometer Test Rig
The test setup consists of Four Cylinder Four Stroke Petrol Engine coupled to Eddy Current Dynamometer. The engine is advanced MPFI Petrol Engine with Electronic Control Unit (ECU). The dynamometer provides variable load on engine to study engine performance under variable load conditions. The engine can be operated at different throttle settings enabling investigation of engine performance at different speeds. Exhaust gas calorimeter is used for estimation of heat carried away by exhaust gases for determination of heat balance of the engine. Air is supplied to the engine through an air box, fitted with orifice plate. Arrangement has been made to conduct Morse Test of the engine to determine its frictional power.
The instrumentation console includes measuring instruments for Engine Speed, Torque, Air consumption, Fuel Consumption & temperature of water, gases.
Experimental Capabilities:
- Determination of brake power & mechanical efficiency at different load conditions.
- Determination of fuel consumption & brake specific fuel consumption, brake thermal efficiency.
- Determination of air consumption & volumetric efficiency, Air/Fuel Ratios.
- Calculation of Heat balance of the engine. To study performance of engine at different operating speeds.
- To conduct Morse test on petrol engine & calculate frictional power of the engine.
