农村中随着柴油机的普及,其耗油量日益增加农民经济负担过重。据机灌站、井试验,综合节能方法如下。 (1) 适当提高柴油机的冷却水温度。其正常出水温度为65～85℃,而当前使用的却普遍低于45℃左右,造成浪费油:(1) 油不能全燃烧,耗油多。(2) 机油粘度大,零件运动摩擦阻力大,耗油高。鉴此,应改善提高冷却水温度为佳。 (2) 保证最佳供油提前角。如195型柴油机的供油提前角为16°～20°。如果柴油机经过一段使用后,柱塞偶件与喷油泵传动件的磨损,供油提前角减小,造成供油时间过晚,油耗大大升高。鉴此,应及时调整。
With the popularity of diesel engines in rural areas, their fuel consumption is increasing day by day. According to the machine filling station, well test, comprehensive energy-saving methods are as follows. (1) appropriate to improve the cooling water temperature of diesel engine. The normal temperature of the water is 65 ~ 85 ℃, while the current use is generally lower than 45 ℃, resulting in waste oil: (1) the oil can not be fully burned, fuel consumption and more. (2) oil viscosity, friction parts movement friction, high fuel consumption. In view of this, we should improve and improve the cooling water temperature is better. (2) to ensure the best fuel supply advance angle. Such as the 195 diesel engine fuel advance angle of 16 ° ~ 20 °. If the diesel engine after a period of use, the plunger coupling and injection pump drive wear, fuel supply advance angle decreases, resulting in fuel supply time is too late, fuel consumption greatly increased. In view of this, we should promptly adjust.
