VANCOUVER, BC – Cummins Westport Inc. (“CWI”) is featuring the new B6.7N natural gas engine at the School Transportation News (“STN”) Conference and Trade Show taking place this week in Reno, Nevada.
On display in the Cummins booth, the B6.7N engine forms part of Cummins Westport’s new 2018 product line, continuing the evolution of emissions leadership for on-highway natural gas engines. The 6.7-liter midrange, factory-built natural gas engine is certified to the California Air Resources Board Optional Low NOx emissions standard of 0.1 g/bhp-hr - 50% lower NOx emissions than current U.S. Environmental Protection Agency regulations.
Rated up to 240 hp, with 560 lb-ft torque, the 2018 B6.7N will also include On-Board Diagnostics, a closed crankcase ventilation system, and a new engine control module. With performance and reliability improvements, the B6.7N offers school fleets a low cost option for targeting ultra low emissions.
“Cummins Westport is excited to introduce the new B6.7N natural gas engine to the school bus market,” said Rob Neitzke, President of Cummins Westport. “We expect the demand for school buses to increase in 2018 as more districts seek to accelerate their emissions reduction strategies. The Cummins Westport B6.7N is a natural choice, offering customers a low emissions reliable product operating on domestically available natural gas.”
As with the other CWI engines, the B6.7N will continue to use a maintenance-free Three-Way catalyst for consistent emissions control, with no diesel particulate filter or selective catalytic reduction required. Customers can choose to fuel with compressed natural gas, liquefied natural gas or renewable natural gas (“RNG”). Using low carbon intensity RNG fuel will further provide significant well-to-wheel greenhouse gas reductions.
Manufactured at the Cummins midrange engine plant in Rocky Mount, North Carolina, the B6.7N comes with two years base warranty, with parts and service support by Cummins Sales and Service.
