By revolting drag test to explosive motor, the revolting drag power and oil consumption compare had been measureed before and after hydroxyl silicate mineral powder additive handling, and proved that the additive can decrease the explosive motor power loss and oil consumption. 通过内燃机反拖试验,对羟基硅酸盐矿物微粉添加剂处理前后内燃机的反拖功率和燃油消耗率进行了测量,证明该添加剂可以降低内燃机功率损失和油耗。
