Cummins diesel generator engine jitter can be combined with sound to judge. For the engine started in place, if there is no obvious abnormal noise, it indicates that the support is not firm. It should be carefully checked whether the suspension is broken, whether the fixing bolt is loose, whether the buffer pad is damaged or fallen off, and timely maintenance.
If the engine of Cummins diesel generator set does not jitter when starting in place, and jitter occurs after starting the drive axle gear, it indicates that the coaxiality deviation of the transmission part is too large. The suspension should be carefully checked for displacement. The inspection method is: when erecting the drive axle, loosen the engine fixing bolt, start the engine to run, and observe whether the engine suspension swings. If there is swing, the coaxial deviation of the transmission part is too large, should be adjusted.
If the Cummins diesel generator engine has abnormal sound and the exhaust smoke color is incorrect after starting in place, it should be eliminated according to incorrect oil injection, uneven oil supply of each cylinder, and non-working of individual cylinders. For the engine that has been used for a long time or works in harsh environment, if the abnormal sound is obvious, maintenance should be carried out according to the loosening degree of each component.
