- The article presents a method of piston temperature measurement on a running engine using electromagnetic induction for transferring measurement results from a moving measuring system placed in a piston to a stationary system attached to the engine crankcase and to measuring system located outside the engine. Selected test results that were carried out on a single-cylinder Diesel engine are presented. A system consisting of a thermistor and a secondary coil was mounted in the piston. The primary coil was mounted in the crankcase under the cylinder liner of the engine. Engine tests were aimed at determining the influence of the piston ring insert on the temperature distribution in the piston. Temperature measurements in the piston without the ring insert were carried out for comparison. In both cases, the pistons had the same geometrical dimensions. The tests were carried out in conditions of external characteristics (the maximum load as a function of engine speed) and load characteristics (load changes at constant engine speed). The test results in the form of the temperature difference between the temperature of piston top and the temperature under the top compression ring indicate that the ring insert is a barrier to the heat flow from the piston to the engine cooling system. In addition, the results of the piston temperature measurements during the step change of the engine speed and its load to the nominal value are presented.
