故障现象一辆斯柯达吴锐2.0T轿车(采用EA888发动机),累计行驶里程约为8.4万km,出现发动机有时起动困难,加速无力的故障现象。检查分析首先使用故障检测仪进行检测,无故障代码显示;接着对该车进行路试,加速正常。而且客户在陪同路试过程中反映,上述故障时有时无,没有故障时加速性能良好,但当出现故障时,最高车速无法达到80 km/h。将该车开回公司后分别检查了高、低压燃油压力数值,显示正常(高压40 bar-190 bar,低压为4.5 bar,1 bar=100 kPa),再通过基本设定107组激活,检测数据系统显示
Fault phenomenon A Skoda Wu Rui 2.0T sedan (using EA888 engine), the cumulative mileage of about 84,000 km, the engine sometimes start difficulties, acceleration weakness phenomenon. Inspection and Analysis First, use the fault detector for testing, fault-free code display; then the car road test, accelerated normal. Moreover, the customer reflected during the road test accompanied by the above-mentioned failure sometimes, acceleration performance without failure, but when failure occurs, the maximum speed can not reach 80 km / h. The car back to the company were inspected after the high and low pressure fuel pressure values, showed normal (high pressure 40 bar-190 bar, low pressure of 4.5 bar, 1 bar = 100 kPa), and then through the basic set 107 activation, test data system shows
