Non-road diesel engines are significant contributors to air pollution in the United States (USEPA, 2004). These engines emit particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and other pollutants. The Clean Air Non-road Diesel Rule was put in place to reduce emission levels from agricultural, construction, and industrial diesel powered equipment. This rule calls for a reduct...

Biodiesel is a low-emissions diesel substitute fuel which is made from renewable sources that consists of the simple alkyl esters of fatty acids. Research and development in the field of biodiesel showed that one way of reducing the biodiesel production costs to compete economically with petroleum diesel fuels is by use the less expensive feedstock containing fatty acids such as inedible oils. ...

Biodiesel has emerged as an alternative to non-renewable diesel fuel. Growing demand for biodiesel has given birth to mal practices such as adulteration which degrade its quality. The present study has dealt with the optimization of biodiesel production from Jatropha curcas oil using a five-level-four-factorial central composite design based on response surface methodology in 54 experimental ru...

The increased use of biodiesel implies variations on both greenhouse gases and air pollutant emissions. Some studies point out that the use of biodiesel blends on diesel can help in controlling air pollution and promote a reduction of CO2 emissions. Reductions on PM, SO2, VOC and CO emissions are also expected, however NOx emissions may increase, which may potentiate O3 formation. This work aim...

Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production. Findings in terms of energy outputs compared with the energy inputs wer...

Increased biodiesel production is being proposed as one solution to the need to ease the impact of increased demand for crude oil and to reduce emissions of greenhouse gases. Despite this, biodiesel has ye...

The contribution of heavy-duty haulage trucks to the concentrations of aerosols and criteria gases in underground mine air and the physical properties of those aerosols were assessed for three fuel blends made with fatty acid methyl esters biodiesel and petroleum-based ultra-low-sulfur diesel (ULSD). The contributions of blends with 20, 50, and 57% of biodiesel as well as neat ULSD were assesse...

Biodiesel production from vegetable oil has gained attention as an alternative fuel to minimize the usage of fossil fuels and reduce greenhouse gases pollution. In Malaysia, oils from local fruit seeds of papaya and rambutan are potential feedstock for biodiesel production due to their high lipid contents and easily available. In the present study, papaya and rambutan seed oils were extracted v...
