FCA recalls 850,000+ gasoline vehicles due to problem with catalytic converters

Green Car Congress

Fiat-Chrysler of America (FCA) will recall more than 850,000 gasoline-powered passenger cars and SUVs due to a problem with their catalytic converters. The recall was announced after an investigation by the California Air Resources Board (CARB) and the US Environmental Protection Agency (EPA).

NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. This indicates that the main VOC source in the LA basin is likely gasoline vehicle emission. Warneke, C.,

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot—black and brown particles that absorb solar radiation—comes from two types of sources: fossil fuels such as diesel, coal, gasoline, jet fuel; and solid biofuels such as wood, manure, dung, and other solid biomass used for home heating and cooking around the world. Particle traps filter out soot particles from exhaust fumes. 1995] and NO.

Study finds air quality models significantly underestimate traffic as source of NOx in Europe

Green Car Congress

Exhaust from modern gasoline powered engines, despite higher ignition temperatures than those powered by diesel, can be effectively treated for NO along with NMVOC (and CO) using a three way catalytic (TWC) converter. Resources. TWC treatment can lead to a 10 fold reduction of NO. —Karl et al. Striednig, C. Lamprecht, A.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. As currently practiced in a country such as Brazil, it can lead to emissions reductions of between 70% and well over 100% when substituted for gasoline. Source: “Assessing Biofuels”.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

Given the current blend limit of up to 15-percent ethanol in gasoline, a maximum of 19 billion gallons of ethanol can be consumed unless the number of flex-fuel vehicles increases substantially. Currently, no commercially viable biorefineries exist for converting cellulosic biomass to fuel.
