MEASURING DEVICES FOR
Multi cylinder SI engine
Quantity to measure & measuring
Engine speed- dynamometer
Air supply to engine(carburetor)- U tube
Various temperature of ic engine- temperature
sensor ( thermocouple, resistance thermometer).
Exhaust gases heat losses- calorimeter
Exhaust Smoke and Emissions
Thermal Efficiency, Volumetric Efficiency
Indicated Mean Effective Pressure, Brake Mean
Effective Pressure etc.
Rope brake dynamometer generally use for
measuring engine speed
A rope is wound around the circumference of the brake drum. One
end of the rope is attached with balance as shown in fig.
Air supply to engine(carburetor)
Generally u tube manometer is use to check inlet air pressure and by
equation air consumption also find out.
by Air Box
Various temperature of ic
Exhaust gases temperature
Inlet air temperature
For measuring this all temperature
there are use different temperature measuring
Silicon band gap temperature sensor
