Cummins X15 with emissions for the USA

ironically, if the regulations were HONEST, then the best way to reduce GHG emissions would be to remove the after treatment systems, and allow the engines to run at maximum efficiency, thereby burning the least possible amount of fuel, and thus producing the least possible amount of CO2.
