Raleigh, North Carolina, aims to lower its greenhouse gas emissions. The city partnered with GoGreen Communications to help achieve its emissions goals and reduce fleet idling. Sign up for Government Fleet eNews! Email Address * Country * By clicking the button below you consent to Bobit's...
and control systems for these emissions (diesel oxidation catalyst, diesel particulate filter and selective catalytic reduction) are discussed. Each type of emissions and control systems is comprehensively examined. At the same time, the legal restrictions on exhaust-gas emissions around the world and ...
On Wednesday, Daimler CEO Dieter Zetsche said that diesel engines can help lower overall carbon dioxide emissions because they emit less than gasoline cars. Environmental activists note, however, that diesels emit more nitrogen oxide, which is harmful for people's health. So far, gro...

On the other hand, diesel fuel, at least as traditionally formulated, produces greater quantities of certainair pollutantssuch assulfurand solidcarbonparticulates, and the extra refining steps and emission-control mechanisms put into place to reduce those emissions can act...
NOx emissions in the dual-fuel engine are lower than those in conventional diesel engines, especially at high loads. At low loads, however, the premixed fuel mixture becomes so lean that much unburned natural gas is emitted, which leads to deteriorated levels of thermal efficiency. Our previous...
Scientific consensus asserts that global greenhouse gas (GHG) emissions must be reduced by 45% from 2010 levels by 2030 to limit global warming to 1.5 °C and minimize climate catastrophe1. The US freight rail sector provides a unique opportunity for aggressive near-term climate action. It tr...

Replacing diesel vehicles with electric and alternative fuel options not only reduces nitrogen oxide emissions, but has the added benefit of reducing emissions of carbon dioxide, a greenhouse gas, from the transportation sector.“The Montana Clean Transportation Program was created to help lower ...
In this study, the combined effects of rapeseed methyl ester (RME) biodiesel combustion with the incorporation of exhaust gas recirculation (EGR) on the engine performance and emissions are analysed and compared with the results obtained from the engine operating on ultra-low sulphur diesel (ULSD)...
