Do you experience turbocharger problem
recently? do you think the problem is caused by material defect or other
cause? or do you think that problem is too early to come?
the main cause of turbocharger failure is
because of the driver or operator habit. the have a belief, that to make
the battery fully charged and be ready for the next start is to increase
engine ROM just before they turn it off. the problem is, when the engine
runs very fast, so does the turbocharger. it needs lubrication as engine
does. but when the engine is turned off, the lub system also stops
working, leaving the turbocharger running in high speed without
lubrication. turbocharger failure also will affect engine performance,
since when the blades hit the housing, some grams will go into cylinders
and causing more fatal damage to engine.
in the other situation, sometimes the
operator waits for the chance to get his bucket filled with materials in
the site. waiting for so long will make engine running in low idle speed
that creates a lot of fuel waste and high concentration of dangerous
toxic in exhaust gas.
to handle this conditions, we create a
device that solve the problem. Engine Delay Stop Control (EDSC), that
will maintain engine in low idle when the driver or operator turn off
the ignition switch, for 30 seconds to wait for the turbo to slowdown to
get enough time for lub, and this device also able to turn off the
engine while waiting for the haul.
