Hidrógeno como combustible complementario para motores de ciclo diésel

The use of hydrogen as a complementary fuel to internal combustion systems search to obtain automotive machines with individual parameters for sustainable development, providing the hydrogen amount required to be used in diesel cycle engines. The aims of this investigation are to use a dry hydrogen cell prototype to quantify the amount released that is optimal for energetic supply to the diesel cycle in standard operating conditions. This research was conducted under a mixed approach, using an experimental, systematic, descriptive, explanatory, correlational, empirical and in a field context, the variables considered for the development of the research are the amounts of hydrogen, diesel, oxygen, time and concentration of the mixture for the experiments. The prototype presented controlled operating conditions depending on the delivered hydrogen flow to obtain the operating curves of the diesel engine (pressure-volume, temperature-entropy), setting the necessary concentration of the mixture for optimum performance for the internal combustion cycle. The combustion systems evolution with hydrogen will tend to optimize performance when characterizing the supply in a controlled manner, depending on the torque in diesel engines under real operating conditions.
