Abstract

A new design of heat flux sensor has been developed in order to allow investigations of the thermal state of IC engines. The sensor was designed to fit within the engine structure and to measure the radial heat flux in an 8mm thick section of cast iron cylinder. The sensor was subject to a substantial calibration process prior to being installed longitudinally down cylinder two of a production diesel engine to investigate the thermal condition of the cylinders during NEDC tests. The heat flux calculated at the top of the bores was highly dynamic and closely followed engine power during transients. The observed heat flux is in the range up to 220kW/m2 during the EUDC part of the drive cycle. The local heat transfer coefficients between metal and coolant are calculated and lay in the range 1.5kW/m2K to 40kW/m 2K.
