Evaluación de las emisiones de gases contaminantes de un motor de combustión interna experimental con diferentes tipos de gasolinas mediante pruebas estáticas

Abstract

Environmental pollution occurs when components that are harmful to human health reach levels higher than the air quality standard and cause damage. For several years the polluting emissions of a vehicle have been constantly reviewed and investigated in order to obtain more efficient engines with low levels of polluting emissions. Reason for which the object of study of this research is the evaluation of polluting gas emissions from an experimental CT150 4-stroke gasoline engine using three fuels used mainly by light vehicles in Ecuador such as: Super gasoline with 93 octane, Extra gasoline with 87 octane and 85 octane Ecopaís gasoline. With the help of the simplified combustion model, the emission factors (𝐹𝐸𝑖) were calculated in grams of pollutant per second because it is a static experimental engine. The results obtained are: for the CO of extra gasoline and eco-country it is between 0.144 g / s and 0.155 g / s, being the lowest for super gasoline. The emission factor for unburned hydrocarbons (HC), the fuel with the highest emissions, is ecopaís gasoline, its values ranging from 0.141 g / s to 0.147 g / s. For the case of the Nitrogen Oxides (NO) emission factor, the lowest value is obtained for super gasoline, which is between 0.005 g / s and 0.007 g / s. Being the least polluting fuel Super gasoline.
