Optimizing The Performance And Combustion Characteristics Of Single Cylinder LHR Based Diesel Engines Using Water Hyacinth Biofuel Blend

Abstract

The growing demand for sustainable energy sources has prompted significant interest in biofuels as an alternative to conventional fossil fuels. Biofuels, derived from renewable organic materials, play a key role in reducing greenhouse gas emissions, promoting energy security, and supporting environmental sustainability. Among various biofuels, biodiesel blends, such as the water hyacinth B20D80 blend, have garnered attention due to their potential for improving engine performance while reducing dependence on fossil fuels. This study examines the impact of zirconia-based coatings on pistons in Low Heat Rejection (LHR) engines, focusing on their effects on performance and combustion characteristics when using the water hyacinth B20D80 biodiesel blend. The results show that the zirconia coating enhances thermal efficiency by minimizing heat loss, leading to improved energy retention within the engine. This reduction in heat dissipation results in better combustion characteristics, including more stable and complete fuel combustion. As a result, the engine demonstrates higher power output, more efficient fuel utilization, and reduced emissions. These findings highlight that zirconia-coated pistons in LHR engines significantly optimize performance and combustion efficiency when using the water hyacinth B20D80 blend, presenting a promising solution for enhancing engine performance with biofuels and contributing to sustainable energy solutions.
