Internal Combustion Engines Pre-ignition is caused by the spontaneous combustion of the mixture before the end of the compression stroke, and is due to Cylinder walls being too hot Red hot carbon deposits on cylinder walls Any one of the listed here Overheated spark plug points Cylinder walls being too hot Red hot carbon deposits on cylinder walls Any one of the listed here Overheated spark plug points ANSWER DOWNLOAD EXAMIANS APP
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 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 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 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 Flow is produced due to the static head in the float chamber ANSWER DOWNLOAD EXAMIANS APP
