Blue some-burning of engine oil
Too much engine oil is filled to oil pan and
enters into combustion chamber when
diesel engine operates
Drain surplus engine oil until
level of engine oil in oil pan is
between H and L oil level of
dipstick.
Clearance between piston and cylinder
jacket increases and engine oil enters into
combustion chamber after long period of
low-load (30% or under) operation
Increase loads properly or select
a Gen-set with proper power.
Piston ring is stuck or worn excessively,
and less in elasticity, or engine oil enters
into combustion chamber
Replace piston ring.
