On July 8, 2004, the Environmental Protection Agency (EPA) certified Cat's full line of off-road engines as compliant with Tier 3 standards, which will go into effect in January 2005 and January 2006. Caterpillar says it is the first company to offer a full line of EPA-approved off-road engines.
The certification of seven ACERT engine models will allow early production of Tier 3 engines and offer customers a full line in the 175- to 750-hp range. Cat says machines powered by Tier 3 engines will reach the market in October 2004—three months before the 2005 implementation date for 300- to 750-hp engines and 15 months before the 175- to 300-hp range required in 2006.
"We've invested heavily in blazing a new path in emissions-reduction technology, and these certifications are proof that the investment is paying off for our company, our customers, and our environment," says Gary Stroup, Caterpillar vice president, Large Power Systems Division.
