6. Periodic Inspection/Maintenance
6.6 Periodical Load Operation to be Performed
[Check and inspection upon each occurrence of the following phenomena]
When a diesel engine driven generator is continuously operated with less light load than 30% or at
no load for a long time, carbon will be stuck inside the exhaust pipe.inside the exhaust muffler and
inside the engine, and unburnt fuel will leak sometimes from the turbo wastegate, connected
portion of exhaust pipe and the outlet port of muffler. If it is continuously operated under the
conditions, the unburnt fuel will ignite and it could cause a fire.
Further, carbon sticking and carbon accumulated could cause power drop of the engine and also it
could cause overheating to the engine, resulting a serious damage to the engine. In case that this
phenomena occurs, eliminate the carbon accumulated by burning it during the operation with a load
burdened until the exhaust gas becomes almost clear.
(For load current, refer to the following table as a standard value.)
A
CAUTION
1-----------------
• Increase the load factor, step by step, paying attention to the exhaust conditions. Also watch the
surroundings because sometimes sparks of fire can come out from the exhaust pipe and the like.
