Less traffic on the roads during the first COVID-19 lockdown in the UK led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise, according to a new study led by researchers at the University of York. These results are a cautionary tale. —Professor Lee.
The study, led by researchers from Imperial College London, found that up to 40% of lead in airborne particles today comes from the legacy of leaded gasoline. The researchers in this study measured lead concentrations of 8 ng/m 3 of air on average during the summer 2018 at Marylebone road. —Senior author Professor Dominik Weiss.
Green NCAP tested 34 cars with different powertrain types: battery electric, hybrid electric, conventional petrol and diesel, and one vehicle, the Ford Puma, that runs on alternative fuel. The LCA calculations used the interactive Life Cycle Assessment tool that is available for consumers on Green NCAP’s website.
The study found that some of the CO 2 savings made during the use of low carbon vehicles is offset by increased emissions created during their production, and to a lesser extent, disposal. —Ricardo Chief Technology & Innovation Officer and Chairman of the LowCVP, Prof. Neville Jackson.
However, a new study by researchers at the University of Gothenburg (Sweden) finds that middle- and high-income earners are generally affected the most by gasoline taxes, especially in poor countries, rather than poor people. Petrol taxes are effective and actually don’t affect poor people disproportionally.
The study examines three different scenarios—Business as usual (BAU); Extended; and Stretch—based on low, medium and high levels of EV uptake. The study also says that other priorities for innovation and investment are reducing the cost and improving the performance of EV batteries, and decarbonizing the grid.
The study, which is authored by researchers from seven universities, several national laboratories and federal government bodies and other organizations, is published in the journal Science. Atmospheric studies that estimate emissions after atmospheric mixing occurs. number of devices).
A new study by a team from Aarhus University in Denmark has found that car dealerships pose a significant barrier to electric vehicle adoption at the point of sale due to a perceived lack of business case viability in relation to gasoline and diesel vehicles. Their study is published in the journal Nature.
The electric F-150 weighs 700 kg more than its petrol-powered predecessor. Smaller electric cars are heavier than their petrol equivalents, too. If US residents who switched to SUVs over the past 20 years had stuck with smaller cars, more than 1,000 pedestrian deaths might have been averted, according to one study.
The study will consist of research and data modeling to assess feasibility for dynamic wireless charging in the UK and the potential for the first real-world demonstrator in the UK. The project is funded through the Ofgem Network Innovation Allowance (NIA) mechanism.
Over the weekend, Ford unveiled a petrol fragrance for future Mach-E GT owners at the Goodwood Festival of Speed. The OEM decided to create the new scent after it commissioned a survey where 1 out of 5 drivers said they would miss the smell of petrol after transitioning to an electric vehicle. The Fragrance is called Mach-Eau.
A study conducted by VTT Technical Research Center of Finland indicates that there is practically no difference between commercial gasoline grades 95E10 and 98E5 sold in Finland as regards fuel consumption in normal driving. The point of this study was to highlight how fuel consumption should actually be measured to give comparable results.

A new study carried out by University College Dublin (UCD) academics has found that under typical Irish commuting conditions, the Toyota Prius IV (fourth-generation) hybrid ( earlier post ) drives in zero emissions mode (ZEV) for significantly more than half (62%) of the time and more than 40% (40.4%) of the distance covered.
Many studies have found health impacts of petrol and diesel car pollution are worse than thought. A new study finds noise pollution also causes big health problems. The post Landmark study links traffic noise to hypertension and cardiovascular disease appeared first on The Driven.
liter EcoBoost petrol engine as a range extender for total range exceeding 500 kilometers (310 miles). These two models are the first vehicles in their classes to offer plug-in hybrid technology, and offer a standard eight-year battery warranty. The new vehicles target a zero-emission driving range of 50 kilometers (31 miles), and use a 1.0-liter
Another study also reported production of even or odd numbered long-chain alkanes in E. In these studies, hydrocarbons were produced by decarbonylation of fatty aldehydes, which are directly generated from fatty acyl-ACPs. Thus, it is of great interest to produce SCHCs directly that have the potential to be used directly as petrol.
NGVA Europe, the European Natural & bio Gas Vehicle Association, has published its own study about the impact on greenhouse gas (GHG) emissions from the use of natural gas as transportation fuel. For heavy-duty applications, benefits compared to diesel are of 16% for CNG and up to 15% for LNG.
Their study confirmed that the mechanical-force-driven stirring process is the reason for the lengthening of the nanotubes. by a team from the University of Texas at Austin noted that of the most studied polymorphs, nanostructured TiO 2 (B) has the highest capacity with promising high rate capabilities. A 2013 paper (Dylla et al. )
We are convinced that we will get a fantastic reaction from the people who use such vehicles on a daily basis: Electric mobility will allow them to travel in city areas which are now off-limits to petrol and diesel-powered vehicles and the range-extender technology makes it possible to use an electric van for normal routine business.
The case study will make it easier to study and optimize other biogas facilities. The plant we have studied is fairly representative of an average biogas plant that processes waste and manure. The plant we have studied is fairly representative of an average biogas plant that processes waste and manure. Mikael Lantz.
The most prevalent use of bioethanol is not as a fuel in its pure form but rather as an additive to petrol. Conventional processes, however, fully purify bioethanol prior to blending it in petrol. In their study, they found that blending 8.75 Click to enlarge.

A 2003 study on victims of the coronavirus SARS found that patients in regions with moderate air pollution levels were 84% more likely to die than those in regions with low air pollution. Those living in polluted cities are more at risk from COVID-19, the European Public Health Alliance (EPHA) warned today.
EV car searches up to THIRTY times more likely to result in a sale compared with petrol/diesel cars, says BuyaCar SEARCHES for electric vehicles (EVs) are up to 30 times more likely to result in a purchase than searches for conventional petrol and diesel-engined cars, according to a new study.
Because they are expensive, biofuels are usually combined with petrol or diesel to make them ‘go further’. The application of this perstraction system to continuous production of a range of higher alcohols is explored and shown to be highly favourable. —Kim et al.
They have been designed and developed as a greener transport alternative, but a new study claims electric cars are a bigger environmental burden than conventional petrol and diesel cars. There’s no question once it’s on the road, a Nissan LEAF is greener than say, a VW Golf, but the criticism surrounds how the vehicle itself [.].
The biofuels currently being produced in New Zealand can only be used to supplement conventional petrol and diesel. The decrease in congestion on Auckland’s motorways when the price of a liter of petrol rose above two dollars in 2007 is testament to this flexibility, he said. These appear as Appendix A and Appendix B. per liter (US$5.12/gallon
Amid all the various new technologies and alternative fuels that have been thrust on the motoring world in recent years as alternatives to regular petrol (gasoline) powered vehicles, it appears that hybrid cars are still the most cost effective solution.
The problem of harmful local emissions has more aspects than the discussion about fuel consumption, and petrol versus diesel. The study was funded by the Norwegian Public Roads Administration, as part of the “EMIROAD” program. —TØI Report 1407/2015.
