Caterpillar announced Dec. 16 that its C11 engine, popular for use in vocational trucks, has earned EPA’s 2004 certification. The 2004 regulations require engine manufacturers to demonstrate lower emissions for nearly double the miles of operation called for in the October 2002 decree. Full production of the C11 engine, offered in the 305- to 370-horsepower range, will begin in the fourth quarter. EPA certified five other Caterpillar engines in 2003 sold in the on-highway truck and bus markets.
