Caterpillar has received environmental certification for two
of its 2007 engines - the C13 and C15, the company reported.
The Environmental Protection Agency must certify that
engines are in compliance with 2007 emissions standards for particulate matter
and nitrogen oxide emissions.
Caterpillar's ACERT technology, according to the company,
reduced emissions through air management, precision combustion, advanced
electronics and after-treatment exhaust and filtration systems.
The C15 has the highest rated torque and horsepower
configurations for heavy trucks, buses, recreational vehicles and fire trucks,
the company states. The C13 is used in heavy-duty lines.
