Internal Combustion Engines The compensating jet in a carburettor supplies almost constant amount of petrol at all speeds because the The diameter of the jet is constant and the discharge coefficient is invariant Jet area is automatically varied depending on the suction The flow from the main jet is diverted to the compensating jet with increase in speed Flow is produced due to the static head in the float chamber The diameter of the jet is constant and the discharge coefficient is invariant Jet area is automatically varied depending on the suction The flow from the main jet is diverted to the compensating jet with increase in speed Flow is produced due to the static head in the float chamber ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines Detonation is harmful due to High intensity of knock causes crankshaft vibration and the engine runs rough Increase in the rate of heat transfer, there is a reduction in the power output and efficiency of the engine None of these Excessive turbulence which removes most of the insulating gas boundary layer from the cylinder walls High intensity of knock causes crankshaft vibration and the engine runs rough Increase in the rate of heat transfer, there is a reduction in the power output and efficiency of the engine None of these Excessive turbulence which removes most of the insulating gas boundary layer from the cylinder walls ANSWER DOWNLOAD EXAMIANS APP
