ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

Green Car Congress

l/100 km) in 2016, the The ICCT team assessed increased consumer label fuel economy (as opposed to the regulatory test fuel economy) to 35 mpg (6.71 The resulting trajectory would reduce CO 2 emissions by half and increase fuel economy by more than 60% from 2016 through 2030.

Their paper is published in the ACS journal Energy & Fuels. Regulated emissions for all test fuels over the cold-start and hot-start LA92 cycles. A fuel economy penalty was also observed for lower energy content E30 and E78 blends compared to both E10 fuels. Data presented as mean ± standard deviation, N=3.

Hagens Berman files class-action fuel economy and emissions lawsuit against Fiat Chrysler and Cummins over SCR defect in RAM 2500 and 3500 diesels

Green Car Congress

The defect leads to lower fuel economy, non EPA-compliant emissions levels, and costly and frequent vehicle repairs, the complaint charges. When the SCR system breaks down, the filter gets clogged, requiring more fuel to be injected to burn it off, according to the complaint.

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

Green Car Congress

g/bhp-hr NO x , which is 90% below today’s standards, with better fuel economy. Penetration of fuel saving technologies into the heavy-duty fleet has been spurred by EPA’s Heavy-Duty Greenhouse Gas Phase 1 Standards, and EPA envisions further penetration of these technologies in order for trucks to meet future Phase 2 requirements.

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.
