供油提前角是指供油开始到压缩上死点曲轴的转角。供油时间过早或过迟直接影响到柴油机的动力和耗油性能。因此,调修喷油泵时必须注意检查调整供油提前角达到最佳位置,这是一项很重要的的工作环节。 每一种柴油机都是通过实验,确定一个供油提前角规定值。但与柴油机的磨耗小时数,装配当否等有关。提前角过大,供油时间 Fuel supply advance angle is the start of compression to the top dead center crankshaft compression corner. Fuel supply too early or too late to a direct impact on the power and fuel consumption of diesel engine performance. Therefore, the repair pump must pay attention to check the fuel supply advance angle to achieve the best position, which is an important part of the work. Each diesel engine is through experiments to determine a fuel supply advance angle regulation. But with the wear and tear of diesel engine hours, assembly and so on. Advance angle is too large, fuel supply time
