Kenworth T440s truck reduces fuel costs

Hribar Logistics chooses CNG-fueled Kenworth T440 to help manage fuel costs and emissions.

Caledonia, Wis.—When Hribar Logistics decided it was time to add a versatile and environmentally friendly truck that would also help reduce fuel costs, the company chose two Kenworth T440s that run on compressed natural gas (CNG).

Hribar Logistics, a full-service trucking and logistics provider, hauls general freight and dry-bulk materials and aggregates. Its 60-truck fleet consists of nearly all Kenworths, and features the Kenworth T800, which is celebrating its 25th anniversary this year. 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.

"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, Wis. "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 fact that the T440 uses CNG fuel also complements our customers’ environmental efforts," Hribar added.

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.

Combined with the use of the Allison 6-speed transmission, which improves throttle response and torque management, superior pulling power is provided to get the job done. The Kenworth T440s come equipped with the Kenworth QuietCab package, 12,000-pound rated taperleaf spring front suspension and Kenworth AG400L air-ride rear suspension rated at 40,000 pounds.
