Peterbilt Motors Company appears set to respond to the recent government funding made available in the US, for ARRA projects, announcing immediate availability of its vocational and aerodynamic vehicles powered by compressed and liquefied natural gas (CNG & LNG). The Model 365 and Model 384 will be offered with the Cummins Westport ISL G and built at Peterbilt’s truck manufacturing facility in Denton, Texas.

SCR Equipped Diesels – An Opportunity for NGVs?
Are natural gas vehicles increasing their role as a simpler, more cost competitive, and more elegant solution?
The increasing complexity of diesel engines is creating opportunities for natural gas vehicles
As diesel powered vehicles face increasingly stringent emissions standards of Euro 5/6 in Europe, and EPA 2010 standards in N. America, more complex engine technology and emissions control systems have been adopted. Particulate emissions have been controlled, in the past, with diesel particulate filters (DPF). Now NOx emissions control for the tighter standards frequently requires a combination of advanced engine control, a DPF, and an emissions control system employing selective catalytic reduction (SCR) with a urea solution injected into the exhaust to control NOxemissions. The cost and complexity of the SCR system has raised the question as to whether, in many cases, natural gas vehicles have become a simpler, more cost competitive, and more elegant solution for meeting the stringent emissions standards imposed on light and heavy duty diesel vehicles.
