California ARB awards $7M for ultra-low NOx heavy-duty diesel truck demo project with Achates opposed-piston engines

Green Car Congress

The project will build and install diesel-fueled two-stroke compression-ignition Achates Power Opposed-Piston Engines into Class 8 demonstration trucks that will be road-road ready in 2019 and operate in fleet service in California in 2020. This program will demonstrate the first diesel engine to comply with the state standard.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

Canada publishes proposed regulations for criteria pollutants from locomotives

Green Car Congress

This marks Canada’s first regulation of air pollutant emissions from locomotives. CACs include NO x ; particulate matter (PM); hydrocarbons (HC), carbon monoxide (CO); and sulfur oxides (SO x ). 1993–2004. 2002–2004. 1973–1992. 2005–2011. 2012–2014. 2015 or later.

Mexico proposes new heavy-duty vehicle emission standards aligned with Euro VI and EPA 2010

Green Car Congress

The current limit values in Mexico are equivalent to Euro IV or EPA 2004 standards. Final adoption of the standard will virtually eliminate fine particle and black carbon emissions from new diesel trucks. Avoided emissions in that year will total 24,000 tons of PM 2.5 , 17,000 tons of black carbon, and 410,000 tons of NO x.
