Abstract

The recovery of waste heat from internal combustion engines has emerged as a critical strategy for improving energy efficiency and reducing emissions in modern energy systems. Dual-fuel diesel engines, while offering flexibility in fuel utilization, exhibit significant thermal losses through exhaust gases. This study proposes an integrated thermoelectric–heat pipe framework designed to enhance waste heat recovery efficiency in such systems. The framework combines thermoelectric generators (TEGs) with heat pipe-based thermal management to optimize temperature gradients and energy conversion efficiency. A structured methodological approach involving thermodynamic modeling, heat transfer optimization, and system-level integration is developed. The proposed system is analyzed under varying engine operating conditions, with particular emphasis on exhaust temperature profiles and dual-fuel combustion characteristics. Results indicate that the integration of heat pipes significantly improves heat flux distribution, leading to enhanced thermoelectric performance. The study demonstrates that optimized coupling of heat pipes and TEG modules can increase energy recovery efficiency while maintaining engine performance stability. The findings contribute to the development of advanced hybrid energy recovery systems and highlight the potential of integrated thermal technologies in next-generation engine architectures.
