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