Title: Experimental Investigation of Thermal Runaway and Failure in an Automotive Engine Using Low-Resolution Infrared Sensing with Preliminary Statistical Analysis
Keywords: automotive engine, engine failure, infrared sensing, thermal runaway

Abstract: This paper presents an experimental investigation of thermal runaway and failure in an automotive engine utilizing low-resolution infrared sensing accompanied by preliminary statistical analysis. A genuine automotive engine was operated under progressively deteriorating thermal conditions until mechanical failure ensued, while a lowresolution sensor captured a time sequence of thermal images from a fixed position above the engine and radiator. The collected data were analyzed through region-based statistical and spatio-temporal features extracted from the thermal image sequence. The findings demonstrate a distinct progression towards critical thermal behavior, characterized by rising temperature levels, increasing thermal non-uniformity, expansion of hot regions, and escalating thermal separation between the engine and radiator.
