B-GAS: Conversion system to Internal Combustion Engine (Diesel) for using alternative energetic source for application in Agricultural Machinery 2019-36-0235

Fuel has a huge port in the operating costs of agribusiness, the increase on the price and the shortage of this energy resource has a direct impact on agricultural production costs. In this context, regions that are farther from refineries and lack the presence of fuel distribution centers tend to suffer more from the availability and cost of this resource. Economically speaking, agribusiness has a prominent position in the national scenery. The world fuel source had an evolution from the predominance of solid fuels to the current age of liquid fuels derived from petroleum and seeing the future and growing age of gas fuels as the predecessor stage of electric vehicles in some markets. Thereby, agricultural organic waste has the potential to generate an alternative energy, clean and ecological matrix, also reducing the emission of polluting gases, soil, groundwater, rivers and weir are still prevented, and the release of greenhouse gases in the atmosphere, such as methane and carbon dioxide. In Brazil, animal waste is normally used for the generation of biofuel, and only 14% of it used in automobiles. Thus, biogas has been studied as a promising energy matrix because it is less polluting and renewable to mitigate the damaging effects of fossil fuels. However, it is highest limitation is the low development of adaptation for Diesel engines, whereupon the project in question is aimed, of which purpose is to develop solutions for existing Diesel engines while maintaining the performance and durability, reducing the dependence of fossil fuels and allowing the use of alternative and cheaper energy sources, produced by the agriculturalists who have space and infrastructure to produce their own fuel, making it self-sustaining. Thus, the development of the project will be guided by the injection of the biogas in the intake manifold in a stoichiometric ratio of air / fuel according to operational necessity, while the biodiesel injected directly into the combustion chamber will be of utmost importance for the start of combustion as pilot flame, since the biogas is unable to combust only with the compression of the cylinder.
