outline: 0px !important;">故障现象: 2010年别克新君威，司机反应发动机故障灯亮，加速无力，发动机工况粗暴，排气管冒黑烟。<img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" fetchpriority="high" decoding="async" width="554" height="248" class="wp-image-644 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232248515-20250305232248365-8888-554w248h.jpg" imgbox-index="0" style="box-sizing: border-box; outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;">故障检修:接到该车后，从询问中得知更换过两个氧传感器，并且因为动力不足从而把三元催化捅掉，捅掉后依然动力不总，排气黑烟更严重。接到该车后第一步连接诊断仪读取故障码，故障码如下图所示:<img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" decoding="async" width="553" height="460" class="wp-image-645 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232252507-20250305232252883-Picture-6-460h.png" imgbox-index="1" style="box-sizing: border-box;

outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;">所报故障都为前氧传感器加热以及混合汽过浓，便读取该车的数据流，该车的数据流如下图所示:<img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" decoding="async" width="550" height="424" class="wp-image-648 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232302371-20250305232302770-Picture-15-550w424h.png" imgbox-index="4" style="box-sizing: border-box;

outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;"><img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" decoding="async" width="546" height="401" class="wp-image-650 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232309155-20250305232309323-Picture-21-546w401h.png" imgbox-index="6" style="box-sizing: border-box; outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;">从数据流中得出，怠速运转当水温达到97℃，在没有开启任何负荷时，进气压力为47kpa，空汽流量为3.03g/s，喷油脉宽达到2.65毫秒，前氧传感器电压一直在0.2V到0.3v.之间跳动。后氧传感器一直在0.9v，排气管都冒黑烟了，前氧所测的电压仍然偏稀，重新清除故障码后，电脑燃油修正仍然一直往浓的方向修正。拔掉前氧传感器后发动机处于开环状态，再加油时时黑烟减轻了，再观察数据流:<img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" decoding="async" width="553" height="373" class="wp-image-651 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232312764-20250305232312357-Picture-24-553w373h.png" imgbox-index="7" style="box-sizing: border-box; outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;"><img alt="图片-2010年别克新君威氧传感器故障案例-蛙趣网" decoding="async" width="553" height="438" class="wp-image-652 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305232315624-20250305232315334-Picture-27-553w438h.png" imgbox-index="8" style="box-sizing: border-box;

outline: 0px !important; height: auto; max-width: 100%; border: 0px; vertical-align: middle; max-height: 100%; display: block; margin: auto;">此时数据流的喷油脉宽、燃油修正、进气压力、空气流量都正常了。故障排除：故更换前氧传感器，故障解决。故障总结:前氧传感器是检测排气管的氧浓度，从而间接反应混合气的比例，为发动机电脑提供信号，控制下一次喷油更精确。而在此案例中，前氧传感器所测量的数据错误导致喷油时间过长，进气量增大，当进气量达到一定时，喷油时间仍然过长，导致排气管冒黑烟，致使动力不足。更换前氧传感器后故障解决。</div><div class="em09 muted-3-color" style="box-sizing: border-box;
