| 摘 要： | 为减少电控喷油器配机的调试工作量,对喷油器油量标定及基本MAP的建立进行了研究,分析了电控喷油器喷油一致性及均匀性的主要影响因素.提出在小油量下,采用压力波动量控制的办法可达到一致性要求,采用喷油脉宽修正的办法可达到均匀性要求.采用变步长方法确定了喷油初始基本MAP,进而检验了基本喷油量MAP的准确性.装机实验结果表明,所建立的初始基本MAP比较合理.

| Abstract: | To facilitate the calibration process of electronic-controlled injector,a study on the calibration of fuel quantity and buildup of basic MAP was made.Chief factors affecting fuel injection consistency and identity were analyzed.A method for fuel injection consistency and identity improvement was designed by controlling the common rail pressure fluctuation and modifying the fuel injection pulse.The initial fuel injection MAP was achieved by the method of variable step interpolation,then the accuracy of the basic fuel injection MAP was tested.A test on an engine equipped with the calibrated common rail electric control injection system was carried out.The experimental results proved the rationality of the initial fuel injection MAP. |
