For new diesel generators and overhauled engines, they must be run-in first, that is, under the condition of maintaining good lubrication, according to the principle of rotating speed from low to high and load from small to large, carefully operate according to the running-in procedures, and then can be put into operation. Formal load operation.


Correctly select the clearance between the piston skirt and the cylinder liner, the opening clearance and side clearance of the piston ring according to the stipulations in the instruction manual. In addition, in the repair, it is necessary to hold the piston biased cylinder, and at the same time to ensure the dimensional accuracy of the cylinder liner.


Keep the normal temperature of cooling water at 70℃~95℃ to avoid overheating of the engine. Warm-up measures should be taken before starting in winter. Operate and use the engine reasonably, do not overload, do not bang the accelerator, and do not start without water. Strengthen the maintenance of the air filter to prevent dust from being sucked into the cylinder. Maintain the lubrication system to prevent mechanical impurities and carbon deposits from mixing into the oil and aggravating the wear of the cylinder liner.
