Diseño de un sistema de alimentación dual hidrógeno/GLP para motores de combustión interna de cuatro tiempos

Abstract

CONDICIONAMIENTO DE PUBLICACION DE PROYECTO. This work presents the development of a dual injection system that combines liquefied petroleum gas (LPG) and hydrogen in conventional four-stroke engines, seeking a practical solution to improve efficiency and reduce the pollution generated by traditional fuels. It was based on an extensive review of studies on alternative fuels, and detailed analyses of the Otto cycle were conducted using this dual mixture. Key aspects such as pressure, temperature, air-fuel mixture, and piston movement were carefully examined to understand how effective this system would be utterly. The results are promising: hydrogen enhances combustion efficiency and speed, significantly reduces harmful emissions such as CO and CO₂, and improves the overall engine performance. However, some important challenges were found, such as the increase in nitrogen oxide production and the need to precisely fine-tune the injection system. Despite these challenges, it can be concluded that this LPG-hydrogen dual system represents a realistic step toward cleaner and more sustainable vehicles, paving the way for new applications in the automotive and energy industries. Keywords: dual injection, LPG, hydrogen, four-stroke engine, combustion.
