Joint EC/EPA presentation Mr. Giallonardo presented working paper HDH-11-08. He indicated that the program was focused on Post-TM testing. Several months of trials and high hybrid manufacturer involvement were needed for being able to run the tests. The complete set-up basically represents a chassis dyno test operated a powerpack test. It was only used for a relative comparison between hybrid and non-hybrid vehicles. It was concluded and confirmed by EPA that chassis dyno testing and powerpack testing compare pretty well for CO2, but differences were observed for criteria pollutants, especially NOx. |
