Engine manufacturers are pushing forward with techniques for reducing emissions, complying with the EPA’s Tier 3 regulations. Technologies developed for use in off highway equipment are being used to power pumps, compressors, and irrigation systems.
Tier 3 regulations call for dramatic reductions in the emission of particulates and oxides of nitrous. Though those regulations don’t phase in for many of these fixed location applications, engine makers are marketing the new engines into these applications.
John Deere Power Systems of Waterloo, IA, is targeting pumps, compressors, and irrigation systems as part of its strategy to sell half its engines outside the company. “Right now, we sell about 45% of our engines outside the company. We’d like to increase that percentage,” says Jim Payton, engine sales manager at Deere (www.johndeere.com/jdpower).
Deere’s PowerTech line has been approved by the EPA. The line ranges from 174-750 hp. Electronic controls are a key technology used to reduce emissions without driving up fuel consumption or reducing hp levels of the engines.
Another factor that helps in these applications is quiet operation. “We’ve put the fuel injectors inside the engine, which really reduces noise,” Payton says.
Cummins Inc. of Columbus, IN, is also moving forward with the Tier 3 QSB engine unveiled in Las Vegas. The line delivers from 135-275 HP. Electronic controls and high pressure common rail fuel systems are key elements of the engines. Its Tier 3 engines are designed to quickly upgrade for Tier 4 regulations that will be phased in in coming years.
