AUTOMOBILE ENGINE OIL FILTER PREHEATING EFFICIENCY ASSESSMENT
It is specified experimentally and analytically that the application of external heating of an oil filter of the motor car engine lubrication system before an on-board electrical heater starts it decreases the intensity of crank shaft bearing wear by 2.4 times on the average per a start-up in the range of initial engine temperatures from 0 to - 12 ºС. However, the average amount of fuel consumed for engine warm up increases by 5%.
