Internal Combustion Engines As compared to air standard cycle, in actual working, the effect of variation in specific heats is to Increase maximum pressure and maximum temperature Reduce maximum pressure and maximum temperature Decrease maximum pressure and increase maximum temperature Increase maximum pressure and decrease maximum temperature Increase maximum pressure and maximum temperature Reduce maximum pressure and maximum temperature Decrease maximum pressure and increase maximum temperature Increase maximum pressure and decrease maximum temperature ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines In a coil ignition system of petrol engines, a condenser is connected across the contact breaker in order to Cause more rapid break of the primary current, giving a higher voltage in the secondary circuit Both (A) and (B) None of these Prevent sparking across the gap between the points Cause more rapid break of the primary current, giving a higher voltage in the secondary circuit Both (A) and (B) None of these Prevent sparking across the gap between the 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 Flow is produced due to the static head in the float chamber 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 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 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 The diameter of the jet is constant and the discharge coefficient is invariant ANSWER DOWNLOAD EXAMIANS APP
