The special result report of the damage
cause of the turbo
The turbo damaged in the
past, and the problems of the vehicles have been verified for eighteen months
of 8 vehicles. A cause could be almost specified recently. Refer to it because
the items which were common to each vehicle were put together.
Matters for commonness
1.ENGINE SUZUKI F6A
2.There are no relations with the mileage and Overhaul, the old vehicles
in the period until
a turbine is replaced which aren't exchanged.
3.The thing that large quantities of sludge are discovered as a cause in
the space from OIL Strainer
to the turbo.
4.What didn't occur in other vehicle kinds.
5.What the same result could get by the actual test.
TEST
1:The test is a turbine
exchange after that without doing an OIL exchange more than 5000km.
2: The test is a turbine exchange after an OIL exchange is done and flashing
is done withou
doing an OIL exchange more than 5000km.
Four units did a turbine blow as a result of changing vehicles by this
test which went each twice.
Of course OIL is exchanged at the time of the turbine exchange as well.
And, after action did the periodic OIL exchange of 2000 more km 3 times
twice, a blow didn't do flashing with an engine of the same condition by
vehicles which replaced a turbine. (test period 5 months)
It let specify the above for the reason. And, because a countermeasure
can't be helped, as for the used car, a countermeasure suggests that a
line from the OIL bread to the turbo is exchanged for the new article as
for the vehicles that past details aren't clear. |
About the air cleaner in sponge form
As for the sponge-shaped air cleaner, the amounts of inflow air decrease
rapidly because it chokes it under the condition that it is inhaled at
the time of the over intake absorption.
In other words, the vehicles which are the condition that the proper amount
of inhalation can't be secured by a sponge's being inhaled to the pipe
part to the rapid amount of absorption any more have been increasing.
A deviation occurs in the part of the core of the center of the turbine
in every direction, and causes a trouble by this.
And, the main causes for play to every direction to be damaged in the cause
vary. An obstruction such as a catalyst inside the outlet is a cause.
It faces the amount of inhalation from the place in intake, the exhaust,
and the environment-making where proper exhaust can be done is important
with the engine which becomes the basis of the motive power. Proper intake
is conversely important against the exhaust, too. F6A's are the vehicles
passing for more than ten years. It is suggested that even the sensor kind
of the vehicles and an electric kind are checked again.
main check items
1:The part being used for the point which fuel passes through
2:The part being used for the point which inhalation air passes through
3:The part which an exhaust gas passes throug.
