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

Green Car Congress

MARCH 14, 2019

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. FCA’s own data and test results confirmed that the catalytic converters in these vehicles were malfunctioning. There are about 50,000 of these vehicles in California.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

NOVEMBER 17, 2009

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. The ozone in the bubble attacks certain pollutants because it is a strong oxidant.

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

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.

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

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.

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. TWC treatment can lead to a 10 fold reduction of NO. —Karl et al.

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”.

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.

As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. The scientists pointed out that converting the epoxides to aerosol is likely to be higher in polluted environments, because the aerosols’ acidity is generally higher when human activity is present.
