Experimental Assessment of a Refrigeration System Powered by a Gasoline Engine Utilizing GasolineBioethanol Mixture

Abstract

Dependable refrigeration is essential for vaccine preservation, especially in distant and resourcelimited areas with unstable electrical supply. Gasoline-powered refrigeration systems present a viable option to electric-powered units; however, their efficacy and environmental consequences necessitate comprehensive assessment. This study investigated the experimental evaluation of a gasoline-powered refrigeration system featuring a micro-cooling compartment specifically intended for vaccine storage. Gasoline-bioethanol blends (E0, E5, E10, and E15) were evaluated in a fourstroke spark-ignition engine to enhance fuel economy and environmental sustainability. The physicochemical characteristics of these blends, such as pour point, octane number, cetane number, viscosity, density, carbon residue, and heating values, were examined to ascertain the optimal fuel composition. The system's effectiveness was estimated using COP. The findings reveal that the E10 gasolinebioethanol blend exhibited significant performance attributes, featuring appropriate octane ratings, viscosity, and density, alongside less carbon residue of 74% and an improved heating value of 410 MJ/kg and COP value of 12%. The employment of the E10 blend significantly reduced CO₂ emissions and enhanced engine performance, rendering it a viable fuel option for gasolinepowered refrigeration systems in this context. This study emphasizes the promise of E10 as a more environmentally friendly and efficient fuel option for gasoline-powered refrigeration systems, enhancing engine performance and aiding in the reduction of carbon emissions. This research provides significant insights into sustainable refrigeration options for vaccine preservation in environments where conventional refrigeration is impractical, hence enhancing public health in neglected communities.
