285HP Example, i.e. a medium bulldozer at landfill


Replace 1989 engine with a Tier 1 engine


½ ton per year of NOx reduced


Almost 1 ton per year of additional emissions reduced (HC,
CO, PM)


Cost Effectiveness


$40,000/ (1.5ton*6 years) = <$5,000/ton emissions reduced

Aftertreatment Success/Opportunities


Passive DPF’s have survived over 6,000 hours
operating in the field


CAT Engineered and CAT Dealer Installed


Active DPF’s that are flexible to various application
requirements are being evaluated


Regen on demand, needs to be operator transparent


Retrofittable NOx aftertreatment strategy will
depend on technical, commercial and regulatory
issues

Conclusions


CAT is actively engaged in providing emissions
retrofit products, but only when they can meet our
standard of excellence


Engine Repowers and Emission Upgrade kits are
an excellent path to reduce NOx, PM, CO and HC


Incentives and outreach are key to spurring interest and
gaining customer acceptance


We continue to assess the latest technological
advances to cost
