Show ; Friction Common Cause of Engine Overheating Every machine, whether a mechanical mechani-cal motor or the human body, requires thorough oiling fu order to secure efficient ef-ficient operation. Where there is improper im-proper oiling, there Is friction, and where there Is friction, heat generates. gener-ates. Heat, In the last analysis, is responsible for burnt-out bearings In motors and death by scarlet fever In human beings. It is generally believed that In the oil sump there lies a pool of oil, Into which the hearings dip and which the motor pump forces Into the various running parts of the motor. This Is only half the truth. When a motor has been running long enough to be warm, it heats the oil and creates a m!t, or fog, of tiny oil particles, which permeates thoroughly ull the lower parts of the motor. The danger In letting your oil supply run low is in thinning out or entirely abolishing this oily mist. This Is a danger you cannot see. Vi.u will be made aware of It by watching the heat Indicator on the r:iriivr cap, however, and should thf mercury In this show a swift rise, look at your oil. Ask your gnruj.t man, and he will tell you that burned hearings, scored cylinder walls anil 1 inken rods are some of his chief Items of repair due to low oil supply. |
