| 摘 要： | 北京现代索纳塔轿车采用2．0L、2．4L4缸发动机和2．7LV6发动机，这几种发动机均采用顶置双凸轮轴、多点燃油喷射和直接点火系统。发动机ECU采用OBD-2型自诊断通信系统，如果发动机控制系统出现故障，ECU会存储相应的4位数故障代码，维修时可利用扫描仪提取故障代码。以2．4L4缸发动机为例，将有关问题简述如下。

| Abstract: | SONATA is equipped with 2.0 L,2.4 L 4-cylinder engines and 2.7 L V6 engine.Double overhead camsha ft,multi-point fuel injection system and direct ignition system are used for these engines.The OBD-2 type self-diagnosis communication system is applied to the engine control unit ECU.When trouble occur in the engine control system,ECU will store a four-digit error code corresponding to the trouble,and the error codes can be read with a scanner when troubleshooting. In the paper,the relative questions are described with a 2.4 L 4-cylinder engine as example. |
