柴油①轻柴油:按凝固点不同,可分为0号、-10号、-20号、-35号等四个牌号。号数是代表凝固点温度的,号数低,凝固点温度就低。反之,号数高,凝固点温度就高。根据不同地区和季节,视气温而选用不同的牌号。如气温在-5℃以上时,应选用-10号柴油。在不受凝固点限制的情况下,各号轻柴油可以互相代用和混合用。②农用柴油:它的凝固点为+20。在气温较高的季节里使用为宜。③重柴油:按凝固点分为10号、20号、30号三个牌号。
Diesel ① light diesel oil: by freezing point different, can be divided into 0, -10, -20, -35 and other four brands. Number represents the freezing point temperature, the number is low, the freezing point temperature is low. Conversely, the number is high, the freezing point temperature is high. According to different regions and seasons, depending on the temperature and use different grades. If the temperature is above -5 ℃, you should choose -10 diesel. In the absence of restrictions on the freezing point of the circumstances, the number of light diesel can be used interchangeably with each other. ② agricultural diesel: its freezing point is +20. In the higher temperature season is appropriate to use. ③ heavy diesel oil: by freezing point is divided into 10, 20, 30 three brands.
