Idling comes from idle which means absence of motion. In the present case IDLING relates to a running engine that is powering a vehicle when it is not moving. An idling engine consumes only enough power to keep itself and its accessories running, therefore, producing no usable power to the drive train. On a school bus, the practice is actually beneficial to the engine during pre-route. It warms the engine and circulates the fluids, preventing the interaction of cold parts, reducing friction and maintaining maximum driving efficiency during route.
U.S. Sen. Herb Kohl recently introduced legislation to provide tax credits for buying hybrid, plug-in hybrid and electric trucks, and idling reduction devices.The Wisconsin Democrat’s bill, the Hybrid and Electric Trucks and Infrastructure Act, was referred to the finance committee with one co-sponsor.
The tax credits would include application to trucks with a gross vehicle weights in several classes, includes those with rating of more than 26,000 pounds and more than 33,000 pounds with a maximum credit of $24,000.The bill also creates a tax incentive of up to $3,500 for anti-idling infrastructure and anti-idling devices installed on trucks, which would expire before 2014. An example of this credit for infrastructure would apply to truck stops installing electrification units.
Finally, S.1285 would extend the tax credit for recharging and refueling infrastructure for plug-in and alternative fuel vehicles.Kohl introduced a similar bill in 2009, which was referred to committee with five co-sponsors.
