Internal Combustion Engines Fuel consumption of diesel engines is not guaranteed at one quarter load because at such low loads The small difference in cooling water temperature or in internal friction has a disproportionate effect The friction is high The friction is unpredictable The engine is rarely operated The small difference in cooling water temperature or in internal friction has a disproportionate effect The friction is high The friction is unpredictable The engine is rarely operated ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The frictional power (F.P.) is given by F.P. = I.P. - P. - I.P. F.P. = F.P. = I.P./ P. P. P./I.P. F.P. = F.P. = I.P. - P. - I.P. F.P. = F.P. = I.P./ P. P. P./I.P. F.P. = ANSWER DOWNLOAD EXAMIANS APP
