Measuring of different parameter of IC engine

  1. 1. MEASURING DEVICES FOR INTERNAL COMBUSTION ENGINE Multi cylinder SI engine
  2. 2. Quantity to measure & measuring devices:  Engine speed- dynamometer  Air supply to engine(carburetor)- U tube manometer  Various temperature of ic engine- temperature sensor ( thermocouple, resistance thermometer).  Exhaust gases heat losses- calorimeter  Fuel consumption  Fuel Air-Ratio  Exhaust Smoke and Emissions  Thermal Efficiency, Volumetric Efficiency  Indicated Mean Effective Pressure, Brake Mean Effective Pressure etc.
  3. 3. Engine speed:  Rope brake dynamometer generally use for measuring engine speed o A rope is wound around the circumference of the brake drum. One end of the rope is attached with balance as shown in fig. Rope brake Dynamometer
  4. 4. Air supply to engine(carburetor)  Generally u tube manometer is use to check inlet air pressure and by equation air consumption also find out. Measurement of Air by Air Box Method.
  5. 5. Various temperature of ic engineInternal temperature  Exhaust gases temperature  Inlet air temperature For measuring this all temperature there are use different temperature measuring sensor  Thermistor  Thermocouple  Resistance Thermometer  Silicon band gap temperature sensor 
  6. 6. Thermocouple and other sensor
  7. 7. Digital sound level meter
  8. 8. Full setup of test rig: Manufacturer:  Nebula equipment  India mart
