The customer started the E/G when the LLC was cool, the valve could not move smoothly and it would interfere with piston. At last, the No.2 valve of No.1 cylinder bent and could not close the cylinder completely. So the No.1 cylinder worked badly with abnormal noise. According to our inspections, the quality of vehicle was normal. We considered that the bad fuel leads to the malfunction. 点检内容概要： 1、进气道检查，积碳异常 The intake inspection and serious carbon distribution could be found. 2、气门检查，1 缸2 号进气气门异常弯曲 The valve inspection and the No.2 valve of No.1 cylinder bent. 3、活塞点检，积碳异常，1 缸活塞顶部与气门干涉 The serious carbon distribution and mark of interference with intake valve were found on the top of No.1 piston. 4、喷油嘴、机油等点检无异常 The oil and injectors were normal. 5、火花塞积碳较严重 The serious carbon distribution covered on the sparks. 6、燃油检查，外观、气味异常 The appearance and smell of fuel were abnormal. 今后对应： 由于涉及油品问题，客户难以接受，指导经销店对应客户。 Because the bad fuel leads to the malfunction, the customer can not accept the technical conclusion easily.
