Internal Combustion Engines The mechanical efficiency (ηm) of the engine is given by ηm = B.P/I.P ηm = (B.P × I.P)/100 ηm = I.P/B.P None of these ηm = B.P/I.P ηm = (B.P × I.P)/100 ηm = I.P/B.P None of these ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The knocking in diesel engines may be prevented by Raising the compression ratio Reducing the delay period All of these Increasing the inlet pressure of air Raising the compression ratio Reducing the delay period All of these Increasing the inlet pressure of air ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines Fuel consumption of diesel engines is not guaranteed at one quarter load because at such low loads The friction is high The engine is rarely operated The small difference in cooling water temperature or in internal friction has a disproportionate effect The friction is unpredictable The friction is high The engine is rarely operated The small difference in cooling water temperature or in internal friction has a disproportionate effect The friction is unpredictable ANSWER DOWNLOAD EXAMIANS APP
