| 摘 要： | 在空燃比传输延迟时间和UEGO传感器(宽域氧传感器)响应时间常数确定以后,利用燃油扰动法打破油膜平衡状态,用UEGO传感器记录汽油机混合气空燃比的变化过程,采用最小二乘法对空燃比测量值进行处理,从而得到燃油动态特性参数值。介绍了标定过程及数据处理方法,并对标定结果进行了验证。

| Abstract: | After the delay time of air-fuel ratio transmission and the response time constant are determined,break the balance state of oil film with the fuel disturbance method,and then record the change process of the air-fuel ratio with the UEGO sensors,then process the measured data of air-fuel ratio with the least square method,thereby obtain the value of fuel dynamic charateristics.The calibration processes and data processing method are introduced,and the calibrating results are verified. |
