Internal Combustion Engines The compensating jet in a carburettor supplies almost constant amount of petrol at all speeds because the The flow from the main jet is diverted to the compensating jet with increase in speed Jet area is automatically varied depending on the suction The diameter of the jet is constant and the discharge coefficient is invariant Flow is produced due to the static head in the float chamber The flow from the main jet is diverted to the compensating jet with increase in speed Jet area is automatically varied depending on the suction The diameter of the jet is constant and the discharge coefficient is invariant Flow is produced due to the static head in the float chamber ANSWER DOWNLOAD EXAMIANS APP
