N atural gas (NG) is a clean-burning alternative fuel with a significant potential for reducing harmful emissions, especially those of fine particles, from vehicles. Vehicular particulate emissions in turn are a concern, because they are small (small particles are especially harmful to health) and numerous, and occur near ground level where people live and work. In response, some have argued fo...

Characteristics of carbonyl compounds (carbonyls) emissions from biodiesel–ethanol–diesel (BE–diesel) were investigated in a Commins-4B diesel engine and compared with those from fossil diesel. Acetaldehyde was the most abundant carbonyls in the exhaust, followed by formaldehyde, acetone, propionaldehyde and benzaldehyde. Apliphatic carbonyls emitted from BE–diesel were higher than those from d...

A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Biofuels such as biodiesel and bioethanol have been studied and tested in many countries including India. One of the methods to reduce the use of fossil fuel is blending ethanol with fossil diesel. However, an emulsifier or a co-solvent is needed to homogenize the diesel-ethanol blends. The ric...

Abstract Lignocellulosic biomass especially, sugarcane bagasse Saccharum barberi sp., appears to be a more suitable material for partial substitution of transport fuel (diesel) than officinarum due its structural similarity (diesel). Besides that, less research has been implemented on this type species. Bio-oil can as biodiesel by processing it further using chemical reactions such hydrodeoxyge...

The taxation of diesel fuel varies by use. Consumers using diesel fuel on-road must pay state and federal highway taxes while diesel fuel consumed for residential heating, industrial use, farming or off-road travel do not pay taxes. Variation in the taxation of diesel fuel creates the incentive for firms and individuals to evade on-road diesel taxes. Firms evading on-road diesel taxes purchase ...
