1.依据当地气温选用柴油牌号国家标准规定:轻柴油的牌号分为10号、5号、0号、-10号、-20号、-35号和-50号7个等级,其中数字表示凝固点,例如5号表示柴油凝固点为5℃。当为柴油机选用柴油的牌号时,其凝固点应低于当地气温5~10℃,例如:冬季最低气温是-5~0℃,则选用-10号柴油;最低气温是-15~-10℃,则选用-20号柴油,如果暂时没有-20号柴油,用-10号和-35号轻柴油掺和起来使用效果也不错;最低气温低于-15℃但不低于-30℃时,选用-35号柴油;最低气温-40℃左右的高寒区,选用-50号柴油。
1. According to local temperature selection of diesel grades National standards: light diesel oil grades are divided into No. 10, No. 5, No. 0, No. -10, No. -20, No. -35 and No. -50 No. 7, of which the figures indicate the freezing point For example, No. 5 indicates that the freezing point of diesel is 5 ℃. For the diesel engine, the freezing point should be 5 ~ 10 ℃ lower than the local air temperature. For example, if the minimum temperature in winter is -5 ~ 0 ℃, -10 diesel is selected; the lowest temperature is -15 ~ -10 ℃, Then the -20 number of diesel, if there is no -20 number of diesel fuel, with -10 and -35 light diesel oil blending effect is not bad; minimum temperature below -15 ℃ but not less than -30 ℃, the choice of -35 diesel; the lowest temperature -40 ℃ alpine zone, use -50 diesel.
