The new 2011 12,000 lb. GVWR NPR named the ECO-MAX uses Isuzu’s 4JJ1-TC engine, which is turbocharged and intercooled. This robust 3.0-liter dual overhead cam directinjection four-cylinder diesel delivers 150 horsepower and 282 lbs.-ft. of torque.
The engine has a 10,000-mile oil change interval and carries a 310,000-mile B10 life rating, which means that 90% of the engines should reach 310,000 miles without requiring overhaul. This engine has been proven around the globe and now, for the first time, is offered to the U.S. market.
The 4JJ1-TC engine employs Selective Catalytic Reduction (SCR) technology to meet the latest and toughest emissions requirements. The SCR system injects Diesel Exhaust Fluid (DEF) into the hot exhaust stream to reduce nitrogen oxide emissions
