REYES, Guillermo G. et al. An examination of polluting emissions using hydrogen and fuel in an internal combustion engine at more than 2,800 a.m.s.l. RCTU [online]. 2018, vol.5, n.1, pp.19-28. ISSN 1390-7697.  https://doi.org/10.26423/rctu.v5i1.287.

The automotive industry is currently looking for new technologies to improve vehicles with respect to their pollutant emissions, with the aim of improving air quality and avoiding the production of harmful gases for the environment worldwide. The performance of an automotive hydrogen generator was analyzed in a comparative way using the standard gasoline fuel injection system and the same standard injection system with 139 ml H₂ per minute through the intake manifold at 1 atm pressure. In this research the dynamometer was tested by means of DIN 70020 for torque - power and the pollutant emissions were tested under the local Technical Norm INEN 2-203 and 2-204. The values of the tests performed on the dynamometer with the presence of hydrogen indicated a power increase of 9.38% over the values of its nominal power. For emissions of pollutant gases, carbon monoxide shows a 23% decrease of its normal pollution at 2500 rpm.

Keywords : Hydrogen; INEN 2-203; INEN 2-204; Altitude; Polluting; emissions.
