Oregon's new rules will speed the transition to electric and lower-emissions trucks, buses, and vans, and likely will inspire other states to also adopt the emissions regulations.
Cylinder deactivation can reduce NOx emissions through hotter exhaust temperatures and allow more efficient engine operation on fewer cylinders under low-load conditions.
Testing of Tula's sophisticated cylinder deactivation control technology on a Cummins engine showed a 74% reduction in nitrogen oxides (NOx) emissions. We talked to Tula's senior engineer about how it works.
Tenneco’s Cold Start Thermal Unit will be combined with Eaton’s TVS blower technology to create an integrated exhaust thermal management system intended to reduce harmful exhaust emissions.
The California Air Resources Board approved sweeping new emissions regulations affecting heavy-duty trucks sold in the state. Truck and engine makers decried the new rule.
The EPA is looking to establish more stringent heavy-duty diesel truck emission standards for oxides of nitrogen (NOx) and other pollutants. The exact rule may well hinge on public comments— and the agency may be deluged by them, both pro and con, given the early reaction.
Report provides an annual evaluation of the agency’s sustainability performance measured across 10 specific performance metrics.
The new ISLG and L9N Near Zero Emission Natural Gas Fueled Heavy Duty Engines will reduce emissions of NOx by 90% and greenhouse gases by 9%.
Yes, it’s a worthy goal to improve the environment and public health by reducing emissions. But you can’t blame trucking for looking at proposals to further cut NOx with a good bit of trepidation.
The company has updated and customized its engines to meet the EPA's near-zero-emissions standards -- without losing fuel efficiency or performance -- by integrating subsystems.
