Internal Combustion Engines The delay period in compression ignition engines depends upon Temperature and pressure in the cylinder at the time of injection Relative velocity between the fuel injection and air turbulence pressure of residual gases Nature of the fuel mixture strength All of these Temperature and pressure in the cylinder at the time of injection Relative velocity between the fuel injection and air turbulence pressure of residual gases Nature of the fuel mixture strength All of these ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The knock in diesel engine occurs due to Reduction of delay period Instantaneous auto ignition of last part of charge Instantaneous and rapid burning of the first part of the charge Delayed burning of the first part of the charge Reduction of delay period Instantaneous auto ignition of last part of charge Instantaneous and rapid burning of the first part of the charge Delayed burning of the first part of the charge ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The compensating jet in a carburettor supplies almost constant amount of petrol at all speeds because the Jet area is automatically varied depending on the suction 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 The diameter of the jet is constant and the discharge coefficient is invariant Jet area is automatically varied depending on the suction 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 The diameter of the jet is constant and the discharge coefficient is invariant ANSWER DOWNLOAD EXAMIANS APP
