The supporting block of the diesel engine oil sump includes the supporting block body, which is provided with a supporting part facing the bottom of the diesel engine crankcase and a connecting part corresponding to the groove shape outside the diesel engine oil sump, and a bolt hole is arranged between the connecting part and the supporting part, and an elastic material layer is solidified in the top area of the connecting part. Due in connection with the contact part of the diesel engine oil pan curing elastic material layer and the elastic material layer made of the original piece and the diesel engine oil sump oil pan into elastic contact rigidity, will the vibration of the diesel engine work passed into the oil pan, the oil sump supporting blocks connected department after curing attenuation of elastic material layer, make the oil sump vibration amplitude decreases, and accordingly reduces the noise caused by vibration of oil pan, thus realize the purpose of reducing the noise of a diesel engine, diesel engine's noise reduction effect is obvious. The oil pan supporting block is simple in structure, low in processing cost and easy to implement.
