Automotive and Construction Equipment for Arctic Use: Heating and Cold Starting
Low-temperature problems with automotive vehicles and equipment begin to appear at about 0 C. Lubricants thicken, batteries lose power, and water in the fuel, oil or other fluids begins to cause problems. Diesel engines that have not been winterized become difficult to start, and they may not start...
