Diesel ethanol, or E-diesel, is a fuel made from diesel and ethyl alcohol. It has benefits such as higher fuel efficiency and lower carbon emissions, but is not widely used due to safety risks and reduced truck performance. Precautions can be taken to reduce risks, and research is ongoing to improve safety and sustainability.
Diesel ethanol, also called E-diesel, is made from diesel fuel combined with ten to fifteen percent ethyl alcohol. It is mainly used in centrally powered vehicle fleets. While there are many benefits to using ethanol fuels, diesel ethanol is not yet widely used. This is mainly due to the fact that there are greater risk factors associated with its use.
The main benefits of using E-diesel are higher fuel efficiency and lower carbon emissions released into the atmosphere. Just like ethanol-gasoline combinations, E-diesel helps increase gas mileage, which has a direct effect on the amount of carbon dioxide emitted into the air. Trucking companies are also able to save money by having to refuel less often.
Despite these benefits, diesel ethanol is not widely used and not legally sold in many areas. This is due to the high flammability of the fuel and the increased risk of combustion and explosion. Fires caused by traffic accidents with diesel-electric powered trucks or trucks carrying the fuel have also increased, although it is not known exactly by how much. When the use of diesel ethanol was compared to gasoline and regular diesel fuels, it was shown to have a higher risk of injury from fire.
There are other problems with using diesel ethanol, including hampered performance of trucks that use it as their primary fuel source. A reduction in fuel pump and fuel projector life, along with reduced performance in these components, has been observed in trucks using ethanol diesel fuel compared to those using standard diesel. This translates into additional costs for trucking companies.
The use of diesel ethanol has been temporarily suspended in some regions due to increased safety risks, but its use has recently been reviewed. There are a number of precautions that can be taken to reduce fire risks so that the use of E-diesel is comparable in safety and risk to petrol or diesel. These include equipping all fuel tanks, filters and fill lines with flame arrestors specifically made for use with ethanol. Installing proper vapor recovery systems and ensuring fuel tanks are of a safe design are other methods used to increase safety.
The use of diesel ethanol is still being researched and modified to ensure maximum safety and convenience. This type of sustainable fuel is of growing importance due to the threat of global warming and the Earth’s diminishing supply of fossil fuels. Because ethyl alcohol is made from a renewable resource, it is a prime choice for increasing fuel efficiency and reducing reliance on fossil fuels.
