Cummins announced low carbon, fuel agnostic platforms this week that will run on gasoline, propane, natural gas, hydrogen and diesel. A 6.7-liter gasoline engine will roll out first followed by a 15-liter nat gas engine which will later be available with diesel. The new approach is seen as a bridge to zero emissions which Cummins says will likely take decades and will lean on improvements in internal combustion along the way.
