Bulldogs dig ASET vocational engines

Mack Trucks Inc. recently announced that 1,000 of its new ASET Vocational engines, engineered to comply with EPA’s October emission regs—are already in service in a variety of fleet applications.

“We’ve said from the beginning that the ASET Vocational engine would be the best choice among the EPA ’02-certified solutions for customers in Mack’s key markets segments and we’re gratified at the positive response to the engine since its introduction,” said vp of marketing Tom Kelly.

Mack had announced what it called a breakthrough in engine technology back in March when it first discussed its ASET (Application Specific Engine Technology) engine line, which also includes models for on-highway applications.

The ASET Vocational engine’s distinguishing feature is its use of internal exhaust gas recirculation (I-EGR) technology, which allows a percentage of exhaust gases to remain in the cylinders of the engine from one combustion cycle to another. According to Mack, this provides a “consistent level of emissions benefits and performance in the varying and often harsh environments in which vocational trucks operate.”

According to Stephen Ginter, marketing vocational product manager, I-EGR was chosen for these engines because internal EGR valve timing is optimal for vocational vehicles that often perform in a stop-and-go manner over shorter distances and for which operating hours are more important than miles travelled.

“We feel the I-EGR engine is more advanced than the engine it replaces,” said Ginter. “It offers competitive fuel economy, improved response for better driveability and quieter operation. In addition, its service interval for vocational users is 300 hours and its miles-to-overhaul mark remains the same.”

Macks available with the I-EGR ASET engines are the Granite Series and the RD6, MR, LE, DM and RB models. The engine will be offered within both the Econodyne and Maxidyne families as well as in a model designed for use with automatic transmissions. Full production of the engines began back in July.
