Expected engine life is generally predicted by the
average power that is demanded. The average
power that is demanded is based on fuel
consumption of the engine over a period of time.
Reduced hours of operation at full throttle and/or
operating at reduced throttle settings result in a lower
average power demand. Reduced hours of operation
will increase the length of operating time before an
engine overhaul is required.
The aftertreatment system can be expected to
function properly for the useful life of the engine
(emissions durability period), as defined by
regulation, subject to prescribed maintenance
requirements being followed.
Aftermarket Products and Perkins
Engines
Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or
consumables (filters, additives, catalysts, ) which are
made by other manufacturers are used on Perkins
products, the Perkins warranty is not affected simply
because of such use.
However, failures that result from the installation
or use of other manufacturers devices,
accessories, or consumables are NOT Perkins
defects. Therefore, the defects are NOT covered
under the Perkins warranty.
