Description

Finding alternatives to gasoline and diesel fuels has been prominent as long as there have been engines to run on them. In recent years, the purpose is to find clean, efficient, and even renewable alternatives. As technology advances, there has been more work and development with feasible alternative fuels.

Compressed natural gas (CNG), primarily comprised of methane (CH4), is an alternative fuel that is the recipient of such research. However, now it is not only just alternative, but also a prominently emerging renewable biogas. The biogas can be produced on cow, and more associated to our research, hog farms. For this project we are working in conjuction with Environmental Technologies, who utilize this process and have revolutionized it to work efficiently, on a mass scale. Utilizing a silo-like digester, a fermentation reaction takes place inside, yielding the biogas. It then undergoes their unique purification process to remove the Sulfur and CO2, and the product is natural gas as clean as what is piped into homes. The use of natural gas in engines has shown to lower NOx, CO2, CO, and in diesels, particulate emissions. The primary goal of the project is to understand the actual affects of running a turbo diesel on CNG-Diesel bi-fuel; doing so by utilizing the EPA standard for emissions testing for over the road diesel engines. Continuing research will then optimize the mixture to keep a constant stoichiometric air:fuel mixture to obtain the most fuel efficiency, and net power, with the largest decrease of emissions, throughout the entire operation of the engine.
