MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. Source of data: US EPA (2019).

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). For instance, hybrid electric vehicles and diesel cars in the small (e.g., Renault Clio) and lower medium (e.g.,

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

The Manufacturers of Emission Controls Association (MECA) released a report assessing market-ready technologies being commercialized by suppliers of emission control and efficiency components for heavy-duty diesel vehicles to meet lower intermediate standards for oxides of nitrogen (NO x ) by 2024 as a transition to final standards in 2027.

KAUST team develops method for reliable prediction of abnormal ignition phenomena

Green Car Congress

Researchers at KAUST’s Clean Combustion Research Center have developed a method to predict and to avoid undesirable combustion events in advanced engines, such as knocking and super-knock. Advanced low-temperature-combustion (LTC) strategies of downsized and boosted engines are capable of offering ultra-low emissions and higher efficiencies.
