Transcript of Measuring of different parameter of IC engine
MEASURING DEVICES FORINTERNAL COMBUSTION ENGINE
Multi cylinder SI engine
Quantity to measure & measuring devices:
Engine speed- dynamometer Air supply to engine(carburetor)- U tube
manometerVarious temperature of ic engine- temperature
sensor ( thermocouple, resistance thermometer).Exhaust gases heat losses- calorimeter Fuel consumptionFuel Air-RatioExhaust Smoke and EmissionsThermal Efficiency, Volumetric Efficiency Indicated Mean Effective Pressure, Brake Mean
Effective Pressure etc.
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
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 Airby Air Box Method.
Various temperature of ic engine- Internal 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
Thermocouple and other sensor
Digital sound level meter
