When the diesel engine driving the generator is running, when air enters the cylinder, oil also enters the cylinder. The main manifestations are blue smoke and significant carbon deposits. The reason is that the space between the piston rings is too large, because the lubrication between the cylinder body and the piston ring relies on splash lubrication by the crankshaft connecting rod, and the excess lubricating oil is scraped by the oil ring. and the space between the oil rings is too large, excess lubricating oil flows into the cylinder for combustion, causing blue smoke. It is recommended to check the piston ring and oil ring clearance. If the gap is too large, replace the piston ring and oil ring with the same type to obtain the standard clearance.
Eight hours later.
