The power generation, used to promote comfort, mobility and others continually grows. 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 shift from conventional and highly inefficient vehicles, being replaced by hybrids or purely electrics. But even with gradual migration for more efficient energy use, we will continue depending of traditional fuels therefore it is necessary to develop more efficient and less polluting ways to use these sources. Thus, this work aims to study alternative ways of converting energy contained in fuels used in internal combustion engines by use of combustion mode RCCI, two fluids with different cetane numbers are introduced into the combustion chamber at different times with the purpose of burning the fuel with lower cetane number. Therefore, for combustion mode RCCI, the SOI of fuel with lower enthalpy of vaporization and the start of combustion must be determined to determine the ignition delay. The results show the ignition delays for the different techniques of injection of fuels with compression ratios of 16:1 and 20:1.
