HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. and PM 10 , including of NTP and TP emissions, at key selected London trial sites.

Vitesco Technologies wins major order for electric heating elements for diesel catalytic converters in 48V MHEVs

Green Car Congress

The capability to heat up the catalytic converter rapidly at all times increases the overall efficiency of exhaust-gas aftertreatment. This means that the vehicles will be prepared to meet the future extremely stringent Euro 7 standard. In the extremely slow “Traffic for London” cycle, NO x emissions fell by 62%.

Brunel to use Camcon Single Cylinder IVT in researching future powertrain concepts

Green Car Congress

Brunel University London is the first to begin researching future powertrain concepts using Camcon Automotive ’s new Single Cylinder Intelligent Valve Technology (SCI). Compatible with most single-cylinder combustion development engines, SCI is designed to plug-and-play straight out of the box.

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

Exhaust from on-road diesel vehicles was responsible for nearly half of the impacts (~181,000 premature deaths) worldwide, and fully two-thirds in India, France, Germany, and Italy. Consideration of these impacts would likely increase the estimate of health impacts from vehicle exhaust emissions.

London and Paris launch car scoring initiative based on real-world emissions; ICCT the technical lead

Green Car Congress

Mayor of Paris and Chair of C40 Cities Anne Hidalgo and Mayor of London Sadiq Khan announced they are working together to create schemes to score new cars based on their real-world emissions and their impact on air quality and to provide that data in an accurate and accessible form to the public.

HEI study finds London Congestion Charging Scheme shows little evidence of improving air quality

Green Car Congress

The London Congestion Charging Scheme (CCS)—which charged for travel into central London and reduced traffic volume ( earlier post )—has shown little evidence that it improved air quality as well, according to Part I of a new study published by the Health Effects Institute (HEI). Resources.

Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel

Green Car Congress

Annual GHG emissions relative to BASE Scenario (BASE Scenario = 949 kt CO 2 e on a 100-year GWP basis) for differing London bus fleet technology options. For the lean-burn CNG scenario, this meant considering exhaust and pipeline supply leaks. Lean-burn CNG is disadvantaged by unburned HC and natural gas pipeline leaks. Cost-benefit.
