Eaton leverages cylinder deactivation and exhaust thermal management technologies to reduce commercial vehicle emissions

Green Car Congress

Power management company Eaton’s Vehicle Group has demonstrated cylinder deactivation (CDA) as an effective technology for meeting future global emissions requirements for diesel-engine powered commercial vehicles. New emissions regulations spearheaded by the California Air Resources Board (CARB), U.S. Rapid catalyst warm-up essential.

IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. A key contribution to this performance must come from the exhaust gas aftertreatment system—across the entire speed and load range. This way, exhaust gas flows through DOC and SCRF before it enters the turbine.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Along with hydrogen production and use, an energy transition will involve the synchronous upscaling of renewable electricity, batteries, and energy use technologies. There is no immediate concern for copper resources, but the average ore grade is declining as higher grade deposits become exhausted. —Palmer et al.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control.

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.
