Although U.S. regulations do not require older engines to meet new exhaust emissions standards, some state and local regulations make that demand.

To help customers who own Caterpillar machines and engines built prior to the implementation of the Environmental Protection Agency's Tier-2 exhaust-emissions regulations, Caterpillar has created the Emissions Retrofit Solutions Group.

The goal of the group is to lower emissions from pre-Tier-2 machines and engines used in such applications as construction, quarry and electric power. Currently offered for in-use diesel engines are repower services, particulate filters, oxidation catalysts and selective catalytic reduction systems.
