Thermal Analysis of Combustion Engine in Accordance to Temperature at the Outside Surfaces of the Engine

Abstract

The internal combustion engine needs to be assessed in terms of thermal loads that come from different sources. Thermal analysis is important in both the design and the evaluation of the conditions of the engine. Interesting good results are obtained by association studies using non-invasive methods such as Infrared and mathematical modelling based on the boundary conditions identified in the experiment. The paper presents a methodology for measuring the surface temperature fields outside of the engine and the mathematical evaluation. The collected material will in future give opportunity to study dynamic thermal states based on the technique of reverse engineering.
