拖拉机、柴油汽车和其它各种高速柴油机使用的燃料是轻柴油。轻柴油具有:①良好的燃烧性。②适宜的蒸发性。③良好的低温流动性。④适宜的粘度。而农用柴油是一种颜色近似黑色的燃料。它的特点是价格低,但蜡质含量较多,凝点较高,且粘度、硫分、灰分及机械杂质含量等都比轻柴油的高。那么,能否将农用柴油用于高速柴油机呢?答案是肯定的。实践证明,高速柴油机使用农用柴油对柴油机各有关零部件的磨损与使用轻柴油相比并无显著差别。只是喷油泵 The fuel used for tractors, diesel cars and other high-speed diesel engines is light diesel oil. Light diesel has: ① good flammability. ② appropriate evaporation. ③ good low temperature fluidity. ④ suitable viscosity. And agricultural diesel fuel is a similar color of black fuel. It is characterized by low prices, but more wax content, higher freezing point, and viscosity, sulfur content, ash and mechanical impurities, etc. are higher than light diesel oil. So, can we use agricultural diesel for high-speed diesel engine? The answer is yes. Practice has proved that high-speed diesel engine using diesel on diesel engine parts and components wear and tear compared with the use of light diesel no significant difference. Just fuel pump
