冬季即将来临,提醒机手要适时更换用油。柴油汽车、拖拉机和各种高速柴油机使用的是轻柴油,根据其凝固点(柴油开始失去流动性时的温度)分为0、10、20、35四种牌号,表示其凝固点分别不高于0℃,-10℃、-20℃、-35℃。因此,各地区要根据不同季节来选用不同牌号的柴油,长江以南地区冬季要使用0号轻柴油,严冬时使用10号轻柴油;长城
Winter is approaching, remind the hands to replace the oil timely. Diesel cars, tractors and various high-speed diesel engines use light diesel oil. According to their freezing point (the temperature at which diesel begins to lose its fluidity), it is divided into four grades: 0, 10, 20 and 35, indicating that their freezing points are not higher than 0 ° C , -10 ° C, -20 ° C, -35 ° C.
