Caterpillar Truck Engine Div. has announced two developments aimed at reducing emissions from its diesel engines. For starters, the engine maker said its new Clean Power engine line, which became available last month, delivers “significantly lower emissions levels than the EPA currently requires without sacrificing performance, fuel economy, driveability or serviceability.”

A Cat spokesman emphasized to FLEET OWNER that while cleaner than the maker's other currently available diesels, Clean Power engines do not meet the emissions regs slated to take effect in October 2002.

While the Clean Power 3126E delivers up to 12% less NOx emissions, the Clean Power C-10, C-12, C-15 and C-16 produce up to 8% less NOx than previous engines, according to Cat. Available ratings will run from 175 to 330 hp. for midrange and 355 to 600 hp. for heavy-duty trucks. Three midrange ratings — 207, 216 and 230 hp. — are certified to meet stricter Low Emission Vehicle (LEV) standards required for the Clean Fuel Fleet Vehicle Program in nonattainment areas.

“These are the familiar, proven Cat engines,” noted David Semlow, marketing manager. “No special fuels are needed, and there are no special-order hassles or chassis issues to contend with. It's the same Cat performance and economy, but in a lower-emissions package.”

Cat also announced new electronic calibrations that it said will cut NOx levels by as much as 7% on most 1993-1998 Cat midrange and heavy-duty truck engines. “The new calibrations will greatly reduce NOx emissions from in-service engines,” said Semlow, “but will in no way affect performance, reliability or fuel economy. He said all that is required is a simple recalibration that can be performed at any Cat authorized dealer.
