齐齐哈尔铁路局地处我国北方,冬季长、气温低。自从配备东风型内燃机车后,每当冬季机车停留时,为了防止柴油机机油和冷却水冻结,就必须起动柴油机,依靠柴油机作功来提高机油和冷却水的温度,并使它们不断流动、传热、防止各有关部件冻结和损坏。我们把这种办法称为冬季机车打温。我局共配备东风型内燃机车83台。自1969年运营以来,为了使内燃机车在冬季能正常运用,每年10月至翌年5月都必须采用机车打温
Qiqihar Railway Bureau is located in northern China, winter long, low temperature. Since DFW diesel locomotives have been installed, diesel engines must be started every winter locomotive to prevent engine oil and cooling water from freezing, relying on diesel engines to increase the temperature of engine oil and cooling water and to keep them flowing and heat transfer , To prevent freezing and damage of all relevant parts. We call this approach the winter locomotive to warm up. I Bureau with a total of 83 diesel locomotives Dongfeng. Since operating in 1969, in order to make diesel locomotives can be used normally in winter, it is necessary to use locomotive to warm the temperature from October to the following May every year
