Evaluating engine durability and operational effects of biodiesel blends in heavy equipment applications

Abstract

This research supports energy transition goals by assessing the viability of biodiesel as a reliable fuel in heavy industrial applications. Through real-time performance tracking and durability analysis, it contributes to optimizing energy use and operational sustainability in high demand environments. In recent years, the use of biodiesel as an alternative fuel has grown significantly, particularly in the transportation, mining, and construction sectors. However, its impact on engine durability and maintenance strategies still requires special attention. This study aims to evaluate the effect of biodiesel blends on engine durability and performance in heavy equipment. The findings provide a foundation for the development of future predictive strategies to optimize maintenance scheduling. The methods employed include an experimental approach using various biodiesel blend proportions (B5, B15, B35) to analyze engine performance on HD785-7 units and the necessary maintenance treatments. Biodiesel testing experiments were conducted on 3 HD785-7 units to evaluate their impact on engine durability. Unit A was monitored for up to 27,000 hours, unit B up to 36,000 hours, and unit C up to 40,000 hours, with each unit dismantled for subsequent analysis. Furthermore, predictive maintenance models can be developed to estimate engine durability based on usage patterns and biodiesel blends. The research results indicate that the gradual use of biodiesel from B5 to B15 and B35 can reduce CO₂ emissions by up to 17% compared to fossil fuels. Additionally, the findings show that heavy equipment operations do not significantly affect engine performance, and specific maintenance treatments can enhance engine lifespan. These findings provide valuable guidance for the more optimal utilization of biodiesel in heavy equipment applications.
