UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. Cars’ average carbon dioxide emissions have dropped by 25% since the early 2000s, according to the US Environmental Protection Agency (EPA), but this gas only accounts for part of the total.

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.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al. Dunmore et al.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

The transition away from gasoline and diesel vehicles to electric vehicles (EVs) is going full throttle in the United States, and that includes the iconic yellow school bus. Roughly half a million school buses transport about 20 million students each school day in the United States, and nearly all those buses currently run on diesel.

Cal Energy Commission approves $1M grant to develop 12L near-zero NOx nat gas engine

Green Car Congress

The California Energy Commission approved a $1-million grant to develop a 12-liter natural gas engine that produces near-zero nitrogen oxide (NO x ) tailpipe emissions. Cummins has a history of developing natural gas engines for heavy-duty application, and its engines are being used globally in a variety of commercial vehicles.

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault recently made public the findings of an internal study, published first in October 2011, detailing and comparing the lifecycle assessments (LCAs) of the battery-electric and two internal combustion engined versions (gasoline and diesel) of the Renault Fluence. Renault assessed the diesel Fluence dCi (1.5L dCi (66 kW).

Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

A study by a team of researchers from France and the US found that the origin of volatile hydrocarbons, other than methane, present in city air is mainly gasoline-powered vehicles. They therefore concluded that gasoline engines are probably the main source of volatile hydrocarbons in both cities.
