GREEN BAY, WI – Paper Transport, Inc. has begun testing prototype compressed natural gas (CNG) equipment.  Specifically, PTI has put into service two tractors with 12-liter CNG engines. 

These two engines produced by Cummins are among a small group of prototypes currently in use.  One engine is in a Kenworth truck and the other in a Freightliner.  Jeff Shefchik, president of Paper Transport says “The 12-liter CNG trucks are an important step forward for us as we look toward more wide spread use of natural gas as a fuel for our trucks.”

The prototype engines provide equal horsepower and torque to engines commonly used in class 8 trucks.  The development of the higher powered units will allow for use of CNG units in higher weight and environments where hills are a concern.  “The full use of CNG trucks had been somewhat limited by the fact that the 9-liter engine was all that was available for a 100% CNG power unit.  The 12-liter’s capability to handle steeper grades will be a nice feature.”

More of the 12-liter engines are scheduled for release in the early part of 2012.  However, full production of the 12-liter model is not expected to begin until the first quarter 2013.

Paper Transport has been utilizing CNG tractors since February of 2010.  They have over 1,000,000 miles on units currently in use.  Another 10 tractors are scheduled for delivery by the end of 2011.
