When configured with the Detroit Diesel BlueTec1-Boxassembly, the Coronado SD truck incorporates a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) catalyst. The 1-Box system is designed to improve fuel economy by reducing backpressure, and it eliminates the protruding exhaust tail pipe — allowing the body to be mounted close to the back of the cab while optimizing weight distri- bution and maximizing payload.
SD is not only ready to take on EPA 2010, it is ready to tackle any chal- lenge,” said Michael D. Jackson, gen- eral manager of marketing for Daimler Trucks North America. Engine cooling is provided by a 1700 or 1900 sq.in. radiator, while a single air
filter provides filtration, using a three- step intake system. Air enters the hood air plenum through the dual air intakes designed to reduce the infiltration of water, snow, dust and road debris. In the plenum, the air is slowed to remove water while optional pre-cleaner filters
are mounted in reinforced areas in the plenum and are designed with circular openings that create a vortex effect to spin the heavy particles out of the air. Bellows are used to push the clean, dry air though a Donaldson Advanced continued on page 19
