MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

FEBRUARY 5, 2020

Source of data: US EPA (2019). The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019.

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.
