Eaton’s family of electric heater power electronics controllers are being developed for solutions between 2 kW and 15 kW of power.
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 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.
The California Air Resources Board has adopted a new emissions tracking program that would help regulators identify vehicles with excess smog-related and greenhouse gas emissions.
Seemingly acting out of character, the Environmental Protection Agency on Nov. 13 announced it will launch a rulemaking to further cut the emission of nitrogen oxide from diesel-powered heavy-duty trucks.
Cummins showed off an emissions reduction concept that promises drastic reductions to NOx and particulate matter emissions in future diesel engines.
As part of a broad-reaching clean air program, California has proposed a low-NOx engine standard for heavy trucks. Truck and engine makers have said in the past that striving for low NOx in diesels could conflict with federal efforts to reduce greenhouse gas emissions by increasing fuel economy.
UK-based Ricardo Inc. says it will partner with the Gas Technology Institute to design the engines to emit fewer NOx emissions while powering medium-duty commercial vehicles.
