The decrease of Cummins diesel generating unit’s load capacity is mainly due to the excessive carbon accumulation caused by the unit’s no-load test for a long time, which reduces the output power of the unit. (Note: Cummins diesel generator set will be based on the environment of the machine room, service life, daily maintenance is not in place, the replacement of equipment and components will appear different degrees of power decline, which is a very important safety hazard, and Cummins diesel generator long time no load or idle operation, resulting in carbon deposition, which will lead to the engine output power reduction, affect the power output of the whole unit, Even cause the illusion of normal operation, once the real load appears Cummins diesel generator set can not run normally major failure.)
Cummins diesel generator carbon accumulation mainly because the combustion chamber temperature is too low, so that the fuel can not be completely burned, caused by carbon accumulation, which blocked the nozzle hole and piston ring, and the exhaust pipe has “black oil” overflow, but also may make the valve stuck. Some unburned diesel will wash the lubricating oil on the cylinder walls and dilute the oil in the crankcase, causing all the running parts of the engine to suffer from poor lubrication. Therefore, in the process of using Cummins diesel generator set, we must pay attention to daily maintenance, the use of environmental health and so on, to avoid the unit carbon accumulation and other failures.
