An additional indirect advantage lies in reducing overall
emissions through the fuel savings benefits. Overall emissions
reductions of industries such as commercial trucking is a step
toward public awareness and demand of clean air and the economical
interests of market and industry efficiency. Further, reducing
emissions in diesels usually requires adjusting engine parameters
(such as injection timing) that result in fuel economy deterioration.
The small inherent emission reduction of the RLE due to the
reduced fueling rate for the same level of power will recover
some of this lost efficiency, in addition to the direct improvement
through friction reduction. 2003 emission levels require the
use of EGR (Exhaust gas recirculation), which is known to increase
the wear rate of the engine. |
