Hribar Logistics, a full-service trucking and logistics provider, has added two Kenworth T440s that run on compressed natural gas (CNG) to its fleet. The company’s choice of the Kenworth T440 natural gas model powered by the Cummins Westport ISL G engine was strongly influenced by both a desire to help reduce emissions that impact the air quality in the greater Milwaukee area and positive past experience with Kenworth trucks.
The two CNG-powered Kenworth T440s are dedicated to an earmarked transportation lane in order to track and compare their performance against documented history of similar Hribar trucks using diesel fuel. The T440s’ ISL G engine uses a maintenance-free, three-way catalyst and is 2010 EPA- and CARB-compliant without the use of selective catalytic reduction (SCR) technology or a diesel particulate filter (DPF). Rated at 320 hp and 1,000 lb-ft of torque, the engine’s torque curve closely matches that of its diesel counterparts, which makes it responsive for Hribar drivers.
“Hribar Logistics prides itself on being on the cusp of new ideas that can influence continuous improvement in the economical delivery of transportation services,” said Mark Hribar, director of fleet operations for Hribar in Caledonia, Wisconsin. “We wanted to do something good for the environment, and also needed a versatile truck chassis that offered a good value by including some of the same features and equipment we get with our larger Kenworths. We embraced the idea of using CNG because it costs less than diesel and helps to increase our country’s energy independence.”
The average nationwide price of an energy-equivalent amount of CNG recently was $1.47 less than a gallon of diesel fuel, according to the July 2011 Clean Cities Alternative Fuel Price Report from the U.S. Department of Energy.
The Wisconsin Clean Transportation Program, administered jointly by the Wisconsin State Energy Office and the Wisconsin Clean Cities-Southeast Area, helped provide funding through a federal grant for the additional up-front cost of the CNG technology.
