Starting fuel injection advance angle acquisition method based on multi-parameter electronic control diesel engine

The invention provides a starting fuel injection advance angle acquisition method based on a multi-parameter electronic control diesel engine. The starting fuel injection advance angle acquisition method adopts a mode of combining arithmetic operation with MAP table query to control the fuel injection advance angle, and solves the problems of insufficient combustion, difficult starting and excessive emission in the starting process of an engine at different temperatures and different rotating speeds. The method comprises the following steps of 1, setting a query table; 2, setting parameter values; 3, reading engine information; 4, calculating a starting initial fuel injection advance angle; 5, calculating a starting initial breakpoint rotating speed; 6, calculating a start-stop fuel injection advance angle; and 7, calculating a starting fuel injection advance angle. 本发明提供了一种基于多参数电控柴油发动机起动喷油提前角获取方法，该方法采用算术运算结合MAP表查询的方式对喷油喷油提前角量进行控制，解决了不同温度、不同转速下发动机起动过程燃烧不充分、起动困难、排放物超标的问题。该方法包括以下步骤：1.设置查询表；2.设置参数值；3.读取发动机信息，4.计
