The paper describes a method of experimental research of ringpack performance, which enables direct measurements of ring axial movements in the groove, pressures in inter-ring lands and temperatures of piston during actual engine operation. The research piston was equipped with a set of sensors and two electronic modules. The set of sensors consists of two piezoelectric pressure transducers, two proximity sensors based on Hall effect, two accelerometers and surface thermocouples. One of the electronic modules incorporates a microcontroller and signal conditioning circuits. The second module contains batteries and optical coupling for communication. Movable data acquisition system enables simultaneous measurement of data from eight channels with high resolution in domain of crankshaft angle. During measurements data is stored in external memory and afterwards can be retrieved and sent to personal computer. Result obtained with the use of developed wireless measurement and data acquisition system will be used in order to validate mathematical model of gas flow and piston rings dynamics.
