Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.

ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

In-use testing of three light duty diesel vehicles—certified to US-EPA Tier2-Bin5 and California LEV-II ULEV emissions limits— found a wide variation in real world emissions performance relative to the regulatory limits. diesels and one 3.0L diesel) over pre-defined test routes exhibiting diverse driving conditions.

EPA and California ARB charge Volkswagen with using software defeat device to circumvent NOx testing in 4-cylinder 2.0L diesels

Green Car Congress

liter, four-cylinder diesels include software (a “defeat device”) that circumvents EPA emissions standards for NO x. The allegations cover roughly 482,000 diesel passenger cars sold in the United States since 2008. Affected diesel models include: Jetta (Model Years 2009 – 2015). collectively referred to here as Volkswagen).

ICCT study finds real-world NOx emissions from Euro 6 diesels ~7x higher than Euro 6 regulatory levels

Green Car Congress

On-road NO x emission levels of Euro 6 diesel cars in Europe are on average about seven times higher than the NO x limit set by the Euro 6 emission standard, according to a new report published in Berlin by the International Council on Clean Transportation (ICCT). Diesel vehicles make up about 50% of all new cars in the EU.
