Now available on Kenworth's website (www.kenworth.com), the Clean Power calculator provides fleets with estimated savings from using the OEM's proprietary no-idle system.

According to the company, the calculator shows the cost difference between Kenworth Clean Power and idling a truck's engine to provide normal hotel loads, including heating, cooling and 120-volt power. To calculate the savings, users fill in a truck's annual fuel use on the web site, along with fuel cost per gallon, annual non-working idling hours, and estimated percentage of the year spent idling for driver comfort.
