This brief presents the technical details and benefits of leapfrogging to Euro VI heavy-duty emission standards and Euro 6 light-duty emission standards rather than progressing through Euro 5/V.

Heavy Duty Vehicles conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.

On December 1, 2014, COMARNAT, the national regulatory committee of the Secretariat of Environment and Natural Resources (SEMARNAT), approved a proposed update by
SEMARNAT to existing emissions standards regulating particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC) and carbon monoxide (CO) from heavy-duty diesel

This study, a meta-analysis of PEMS data from EU (Euro 6) and US (Tier 2 Bin 5/ULEV II) diesel passenger cars, documents the wide discrepancy that exists between official certification or type-approval emissions of nitrogen oxides (NOx) from new diesel passenger cars and actual NOX emissions from those vehicles during real-world, everyday operat

Mexico is planning to revise its existing emissions standards for diesel heavy-duty vehicles (HDVs). The existing regulation, Norma Oficial Mexicana 044 (NOM 044), requires new vehicles to meet either U.S. Environmental Protection Agency (EPA) 2004 or Euro IV standards.

Plans to charge drivers of diesel cars about £10 to drive into central London are being considered.

This is one drive that is definitely going to make the Capital's air cleaner and traffic flow smoother.

Auto major Tata Motors and Canada's Westport Innovations today launched a spark-ignited natural gas engine meant for use in medium commercial vehicles.

The new engine features the Westport WP580 Engine Management System (EMS) and is designed to support various configurations.

This report focuses on heavy-duty natural gas engine technologies that can achieve Euro III, IV, V and VI emission compliance levels. It is based on a comprehensive review of technical literature regarding emission performance &  technologies was performed for compressed natural gas engines of model year 2000 and newer.

European Commission has recently proposed a particulate matter (PM) number limit for light-duty diesel vehicles under the Euro 5 and Euro 6 emission standards. To ensure that emissions of utlrafine particles are controlled, the commission has set up this new regulatory approach that tracks emissions in terms of mass and numbers. The proposed PM number emission limit is 5x1011 particles per km. It will be applicable to all light-duty diesel vehicles at the Euro 5 (effective from 2009) and Euro 6 (effective from 2014) stage in Europe.
