一是提高柴油机冷却水温度农用柴油机出水温度普遍低于４５℃，使柴油机完全不能燃烧，机油黏度大，加大了运行阻力，因而耗油多，故需提高柴油机冷却水的温度。 二是保证最佳供油提前角１９５型柴油机供油提前角度的最佳角度为１６”～２０”。当柴油机使用一段时间后，由于柱
First, to raise the temperature of diesel engine cooling water Agricultural diesel engine water temperature generally below 45 ℃, so that the diesel engine can not burn, oil viscosity, increased operational resistance, and thus fuel consumption, it is necessary to improve the temperature of diesel engine cooling water. Second, to ensure the best fuel supply advance angle 195 diesel engine fuel supply angle of the best angle of 16 “~ 20”. When the diesel engine is used for some time, due to the column
