CARB proposes to amend MY 2024 low NOx standard
Given the lack of MY 2024 compliant new engine introductions, California has proposed an amendment to its low NOx omnibus, providing more flexibility for legacy engines.
CARB deal with OEM on low NOx, electrification – and H2 ICE ?
California and Truck & Engine Manufacturers have reached a deal on low NOx and electrification targets in the state. This paves the way for more regulatory certainty but the challenges ahead are not diminished.
Technology Deepdive : Opposed piston engines
Opposed piston engines are being developed as a tool to reduce CO2 and NOx emissions from heavy-duty trucks. Here’s a deeper look into this technology and recent test results.
U.S. EPA Phase 3 Greenhouse Gas Proposal for Heavy-Duty Vehicles
A downloadable summary of the U.S. EPA announced the Phase 3 GHG proposal for heavy-duty vehicles. From 2027 to 2032, 45% reduction in CO2 emissions for light vocational vehicles and 25% for Class 8 sleeper cabs. Over half of light vocational and a quarter of sleeper cabs expected to be ZEVs by 2032.
