【摘要】 从节能减耗和能量回收的角度,研究了非道路电控柴油机排放耐久台架试验法的等效工程替代法,探讨了等效试验的判定原则,建立起初步的数值关系模型。基于ECU采集的柴油机运行相关参数,同时结合标定和校准数据库,计算电控柴油机的输出功和燃油消耗量。台架试验与工程替代试验的对比测试在电控共轨188F型柴油机上进行。结果表明:工程替代法精度上能满足一般工程需要。从而证明了在一定条件下,非道路电控柴油机的排放耐久试验采用工程等效替代法技术上是可行的,应用价值巨大。更多还原

【Abstract】 To achieve the saving,reduction and recovery of energy,the equivalent engineering alternative method of non-road diesel engine emission endurance bench test was studied. The determination principle of equivalent test was discussed,and the preliminary numerical relationship model was established.Based on the operation parameters of diesel engines collected by ECU,and combined with calibration database,the output power and fuel consumption of electronically controlled diesel engine were calculated.The bench test and engineering alternative test was carried out on an electronically-controlled common rail188 F diesel engine. The results show that the engineering alternative method could meet the normal engineering requirements. Therefore,it is proved to be feasible to apply the engineering equivalent alternative method to the emission endurance test of non-road electronic controlled diesel engine under certain conditions,and is very valuable in application.更多还原
