Temperature Measurements of the Piston surface in a Research Compression Ignition Engine in Transient Conditions for 1d Model of Heat Transfer
Analysis of heat losses in internal combustion engines (ICEs) is fundamental to evaluate and improve the engine efficiency. Detailed and reliable heat transfer models are required for more complex 1d-3d combustion models. At the same time, the thermal status of engine components, as pistons, is needed for an efficient design. Measurements of piston temperature during ICEs operation represent a precious and challenging result to get for the aforementioned purposes. In previous works, the authors, first, evaluated and, then, measured the temperature of the optical window in a research compression ignition engine via thermal imaging and thermocouple installation, respectively. The tests concerned steady state and transient conditions.
