Research from the University of Michigan shows that switching to fuel cells or batteries can reduce lifetime greenhouse gas emissions by up to 90% compared to diesel-powered vehicles. The study found that hydrogen fuel cells and battery electric powertrains offered the largest emissions reductions.
Southwest Research Institute uses machine learning to automate calibration of heavy-duty diesel truck emissions control systems, cutting calibration time from weeks to hours. The new method improves system performance while ensuring compliance with upcoming standards.
A new study published in The Journals of Gerontology: Series A found that long-term exposure to high levels of air pollution is associated with lower scores in key cognitive abilities, especially language skills. Exposure to nitrogen dioxide and fine particulate matter was linked to poorer language performance.
Interest in second-hand electric vehicles (EVs) has doubled from 3.5% to 7% of advert views between 2022 and 2023, indicating a potential tipping point in the UK used car market. This growth is driven by 'sticky' interest that lasts longer, suggesting drivers are becoming more receptive to EVs.
A new study finds that battery-powered electric vehicles (BEVs) have improved significantly in reliability over the years, matching the lifespans of traditional cars and vans with internal combustion engines. BEVs now have an average lifespan of 18.4 years and can travel up to 124,000 miles.
A comparative study by Lero reveals that electric vehicles have a higher chance of experiencing an at-fault insurance claim, with a 4% increase in crashes compared to internal combustion engines. The research also found that hybrids show no further increased risk, indicating EVs have a higher risk profile.
A new study by the University of Eastern Finland found that preheating a vehicle has minimal effects on both fuel economy and emissions under cold winter conditions. While preheating showed some benefits in terms of engine comfort and wear reduction, its impact on overall fuel consumption was only slightly lower than after a cold start.
A new study published in Environment International reveals that vehicle exhaust filters have limited impact on reducing ultrafine particles, which are a major contributor to air pollution. The research shows that current filters are not effective at removing smaller liquid particles, highlighting the need for alternative measures to re...
Researchers at Argonne National Laboratory have identified promising new biofuels that can reduce greenhouse gas emissions by up to 60% while improving fuel efficiency or reducing tailpipe emissions. The biofuels, developed using advanced engine design, can be blended with conventional fuels to improve engine performance and meet more ...
A new study from Finland found that passenger car preheating produces significant particulate emissions equivalent to driving dozens of kilometers. The study measured auxiliary heater emissions and compared them to calculated emissions from driving, revealing the impact of preheating on air quality.
A new study published in Applied Economics challenges the long-held 80-20 rule in F1, finding that car and team input accounts for 20% of success, while driver skill accounts for 15%. The interaction between driver and team is found to be the biggest factor, accounting for 30-40% of success.
Researchers at KAUST developed a new exhaust catalyst concept that can effectively remove NOx from vehicle emissions, resolving an ongoing debate over additive atoms in the catalyst mix. The team identified the ideal atomic recipe to catalytically remove NOx from diesel car tailpipes.
A new MIT study finds that 10 major European auto manufacturers produced diesel cars emitting up to 16 times more NOx on the road than in lab tests, resulting in approximately 2,700 premature deaths per year across Europe. Improving emissions control technologies could prevent up to 1,900 premature deaths annually.
A NUS-led study reveals that a beltway in Sao Paulo diverted heavy-duty diesel vehicles, reducing public health damage from diesel emissions. The intervention led to a sustained drop in nitrogen oxides levels and improved air quality.
A new study estimates that excess NOx emissions from diesel cars cause approximately 5,000 premature deaths annually in Europe. Respiratory and cardiovascular diseases are the main causes of these deaths, accounting for around 90% of cases.
A six-nation study published in Scientific Reports reveals that modern diesel cars generally emit less pollution than gasoline-powered cars. Diesel's cleaner reputation is due to its lower invisible pollution, which outweighs the more visible emissions from gasoline vehicles.
A team of UC Riverside researchers is working with the California Air Resources Board to improve a method for measuring diesel particulate emissions. The research could provide the groundwork for strengthening standards for diesel particulates, and has already led to the collection of over 24,000 analytical samples.
A new study by the Swedish Environmental Protection Agency reveals that diesel cars emit significantly more nitrogen oxides, particulates, and carcinogenic substances than petrol-driven cars. This trend is counterproductive to achieving environmental goals for cleaner air and reduced acidification and eutrophication.
