Manufacturer Approaches to Meeting More Stringent Emissions Standards
By Seth Skydel
Scheduled for production in 2026, the Cat C13D engine is targeted for a wide range of off-highway equipment.
Vehicle, engine and powertrain developments were discussed at EUFMC 2024 by manufacturer representatives.
In two developments this year, the U. S. Environmental Protection Agency( EPA) announced greenhouse gas( GHG) emissions standards for heavy-duty vehicles – Phase 3 and multi-pollutant emissions standards for model years 2027 and later light-duty and medium-duty vehicles. Both final rules set stronger standards beginning with model year( MY) 2027.
The Phase 3 standards are applicable to heavy-duty vocational vehicles, including some utility trucks and tractors. Depending on vehicle type, the standards are up to 60 % more stringent than the previous Phase 2 standards. The new light- and medium-duty standards build on federal greenhouse gas emissions rules for model years 2023 through 2026. These standards will phase in from 2027 through 2032.
EPA’ s new emissions standards recognize continued advancements in technologies that enable significant reductions in harmful air pollutants, and under the performance-based standards manufacturers can choose the mix of technologies they believe are best suited for fleets, including:
● Advanced gasoline engines and transmissions
● Hybrid electric vehicles( HEVs)
● Plug-in hybrid electric vehicles( PHEVs)
● Battery-electric vehicles( BEVs)
The light-duty vehicle standards apply to passenger cars, light trucks and heavier vehicles designed primarily for the transportation of people. The medium-duty vehicle( MDV) category includes heavy-duty Class 2b and 3 vehicles( vehicles with a gross vehicle weight rating( GVWR) between 8,501 and 14,000 lbs.), primarily large pickups and vans that are typically used for work due to their higher towing and hauling capabilities. Class 4 and higher vehicles remain under EPA’ s heavy-duty vehicle program.
Vehicle, engine and powertrain developments were discussed at EUFMC 2024 by four manufacturer representatives. The panelists covered 2027 emissions regulations and zero emissions vehicle requirements for trucks and equipment. In addition, they related plans for next generation battery electric, fuel cell electric and hydrogen internal combustion engines and fuel agnostic engine platforms.
