Implementación de un sistema GLP a un motor de combustión interna a gasolina para sus posterior análisis comparativo de torque, potencia y emisiones de gases

Abstract

This study focused on the implementation of a Liquefied Petroleum Gas (LPG) system in a gasoline internal combustion engine, with the purpose of performing a comparative analysis of torque, power and gas emissions at 2700 meters above sea level (masl). We began by defining the research problem, its general and specific objectives, as well as the theoretical, methodological and practical justification of the study, including null and alternative hypotheses. In addition, an exhaustive investigation of the research background related to the conversion of gasoline engines to LPG and the implementation of LPG systems in gasoline internal combustion engines was carried out, addressing theoretical concepts on internal combustion engines and spark ignition engines (MEP), as well as the fundamentals of LPG as an alternative fuel. Defining the delimiters of the research, the methodological framework of the study was developed, detailing the research approach, the schedule of activities and the description of the scheme and development of the project, including the steps from the identification of the problem to obtaining data on torque, power and gas emissions with conventional gasoline and LPG systems, through the results obtained after the implementation of the LPG system, including the analysis and interpretation of the data, the evaluation of tests and trials, as well as the comparative study by means of ANOVA statistical analysis and the generation of specific fuel consumption maps, a variation of 3.2% in torque and 0.42% in power was obtained after the conversion. In addition to a significant reduction in gas emissions, highlighting the reduction of 6.6% in CO2. Based on the results, it is expected to contribute to the scientific and technological knowledge in the field of internal combustion engines and the use of LPG as an alternative fuel.
