American Power Group to Develop Low NOx Dual Fuel Exhaust System

 

American Power Group announced funding has been approved for the initial production development phase of a low NOx solution for 13 liter to 16 liter Class 8 diesel engines that are model year 2010 and newer. The patent-pending design incorporates APG’s CARB certified dual fuel natural gas system with APG’s new Exhaust Thermal Management System (ETMS). APG’s ETMS is designed to create a quicker warm-up and maintain optimal temperature performance of a diesel engine’s selective catalyst reduction system to significantly reduce smog-forming NOx production.

The system is expected to reduce NOx 50 percent to 75 percent below today’s EPA and CARB NOx standards, which would qualify diesel engines upgraded with APG’s Dual Fuel/ETMS system to meet California’s Optional Low NOx diesel engine emission standards. Initial phase emissions testing will be performed this spring at the Center For Alternative Fuels, Engines, and Emissions (CAFEE) at West Virginia University.

“There are millions of 13L to 16L high-horsepower diesel engines on the road that cumulatively rank as the number one source in NOx emissions,” said Lyle Jensen, American Power Group Corporation’s CEO. “The existing APG V5000 and the new APG V6000 with ETMS have the opportunity to fill this void with no loss of power on legacy diesel engines and present options for a new dual fuel natural gas low NOx high-horsepower Diesel/SCR engine for the heavy-haul OEM market.”
