Hybrid construction vehicles vs. convention diesel: Which one wins with emissions?
Behavior of those vehicles will be characterized on a second-by-second basis during in-use operations at construction sites using portable emission measurement systems. Researchers will design standardized tasks, such as lifting a heavy object.
The performance of the hybrid vehicle will then be compared to that of conventional diesel powered vehicles.
The project will help establish the methodology for making comparisons under such varied conditions. The project will also consider the differences between emerging hybrid implementations by leading manufacturers.
The project may provide data that could contribute to a hybrid incentive program under AB 118, a 2007 law that established voluntary incentive program administered by CARB to fund clean vehicle and equipment projects, research on biofuels production and the air quality impacts of alternative fuels, and workforce training.
