Reactivity Controlled Compression Ignition (RCCI) for the Mixture of Diesel Fuel and Hydrous Ethanol in a Rapid Compression Machine 2015-36-0101

The power generation, used to promote comfort, mobility and others continually grows. The demand for energy grows as much as the number of studies in this field. To solve this growing demand, efforts have been directed towards the development of new energy sources, preferably renewable, and better ways of energy conversion by increasing the processes efficiencies. A good example of this is the gradual change from conventional and highly inefficient vehicles to hybrids or purely electric ones. But even with gradual migration for more efficient energy use, we will continue depending on traditional fuels. Therefore, it is necessary to develop more efficient and less polluting ways to use these sources. Thus, this work aims at studying alternative ways of converting energy contained in fuels used in internal combustion engines. By the use of the combustion mode RCCI, two fluids with different auto-ignition characteristics are introduced into the combustion chamber at different times, with the purpose of burning the fuel with lower power auto-ignition. The amount of each fuel and start of injections (SOI) are parameters that strongly influence the combustion. The results show the parameters for the different techniques of injection of fuels with compression ratios of 16:1 and 20:1.
