| Abstract: | Aiming at the abnormal wear of cylinder liner and piston ring in a marine low speed diesel engine,combined with the structural characteristics and operation requirements of cylinder liner,the fault causes were investigated and analyzed.The results show that:The main reason of the abnormal wear of cylinder liner and piston ring was the use of inferior cylinder lube oil with alkali value much higher than the standard;The secondary cause was that the condensate of the air cooler was not discharged smoothly.On this basis,the key points during each stage of operation and maintenance of low speed diesel engines are put forward. |
