Investigar el comportamiento de los gases contaminantes al implementar inyección de hidrógeno en un motor a gasolina para optimizar el proceso de combustión.

Abstract

In this research work, the behavior of pollutant gasses was analyzed by implementing hydrogen in the gasoline engine of the Aveo Family 1.5 car. The hydrogen generator system operates through the chemical principle of electrolysis, which is a process that separates water molecules into oxygen and hydrogen. This is achieved with the help of potassium hydroxide electrolyte also known as caustic soda and the support of the electric current supplied by the car s battery. Using a 5A DC voltage regulator that controls the electric current of the hydrogen generator system, hydrogen proportions of 50 percent and 100 percent of the total capacity produced by the generator were reached. With these obtained proportions, hydrogen was injected into the internal combustion engine. In the development of the proposal, the practice of implementing the hydrogen generator system in the Aveo Family car was carried out, and the measurement of pollutant gasses was performed using only extra gasoline, applying hydrogen at 50 percent and 100 percent due to the properties of hydrogen. The hydrogen injection percentage at 50 percent and 100 percent was improved as it significantly reduced Unburned Hydrocarbons HC ppm, obtaining an average result between high and low revolutions of 160 ppm at 50 percent and 96 ppm at 100 percent, representing a viable alternative for the combustion of these engines.
