When left when the test-drive after repair in shop main engine is adding this ship to 540r/min, supercharger occurrence asthma brace up phenomenon, rotate speed lifts slightly again, noise shakes very big, smoke evacuation temperature is normal, hair of on the high side of temperature of air inlet duct is very hot, as good as of smoke evacuation smoke constant, supercharger rotor rotate speed and the rotate speed of right leader supercharger that work normally comparative. 2 breakdown analyse this model diesel engine supercharger breathes heavily brace up the reason has the following sides. Bearing of 1 supercharger rotor damages, bring about on the low side of supercharger rotor rotate speed or wave motion, make inadequacy of compressor part air feed and diesel engine and its demand do not match, bring about air current not to stabilize generation to breathe heavily brace up. 2 diesel engine offers oil, match gas to time forbid, match gas, draw well time and disorder, bring about supercharger to breathe heavily brace up. 3 supercharger nozzle jams, cause smoke evacuation not free, circumfluence of exhaust stroke waste gas, enter jackknife of new energy of life with the below one stroke that take energy of life, produce air current to hit generation to breathe heavily brace up. Canal of 4 smoke evacuation jams, smoke evacuation not free, bring about waste gas circumfluence, hit generation of new energy of life to breathe heavily brace up. 5 jams into gas mouth, enter gas inadequacy, generation breathes heavily brace up. 3 trouble removal are based on above analysis, adopt the following measure to remove trouble.
