The Impact of Thermal Management Technology on Engine Performance

Abstract

With the continuous development of the automotive industry and the increasing stringency of emission regulations, engines are required to achieve high efficiency, low fuel consumption, and low emissions simultaneously, which places higher demands on the thermal management system. As a core approach for regulating engine temperature fields and energy flows, thermal management technology directly affects the engine’s thermal efficiency, durability, and emission levels. Through a literature review, this paper systematically analyzes the mechanisms by which thermal management technologies influence engine performance. It further discusses the applications of advanced cooling systems, waste heat recovery, nanomaterials, intelligent materials, and thermal management in new energy vehicles. The results indicate that advanced thermal management technologies can significantly enhance engine efficiency, extend service life, and reduce environmental impact. However, current systems still face challenges such as high complexity, increased costs, and limited material reliability. Future trends point toward intelligent control, multifunctional material applications, and deeper integration with new energy vehicle thermal management. This study provides valuable references for researchers and engineers working on energy optimization and engine performance improvement.
