The article presents a method and algorithm for solving the inverse time-dependent external heat conduction problems in the combustion chamber of the internal combustion engine. Both the method and algorithm provide calculation of the thermal boundary conditions on the heat receiving surface parts. The authors analyze the advantages and disadvantages of different methods. The article describes an example of solving the inverse time-dependent external heat conduction problem for a heat sensor.
