EPA said its new emission standards for oxides of nitrogen (NOX) from medium- and heavy-duty on-highway engines are more than 80% stronger than current standards.
Eaton’s family of electric heater power electronics controllers are being developed for solutions between 2 kW and 15 kW of power.
The Truck and Engine Manufacturers Association said the California Air Resources Board's new emissions regulations don't give manufacturers enough time to comply.
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.
Jacobs Vehicle Systems and Tula Technology have signed an agreement to accelerate the development of Jacobs cylinder deactivation valve actuation technology in conjunction with Tula’s dynamic skip fire control algorithms.
Cylinder deactivation can reduce NOx emissions through hotter exhaust temperatures and allow more efficient engine operation on fewer cylinders under low-load conditions.
The cleanest natural-gas-powered trucks will be exempt from the Port of Long Beach Clean Truck Fund Rate as a transitional step to zero-emissions trucks becoming widely available.
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.
