Whether it is associated with some stalls, it is very important to judge the transmission fault, if a sound file, is associated with part of the influence of the file transmission; if all files are sound, is often a constant mesh gear shaft fault or transmission oil. Whether it is related to a particular action, such as addition, downshift, start, rapid acceleration, rapid deceleration, turning and so is the effective means to judge the loudness of the transform speed, to determine the changes of direction after the bridge fault is particularly important.
Solution: engine abnormal sound indicates that the technical state of an engine has changed. Mainly due to some parts worn or even assembly, improper adjustment caused.
