ABSTRACT:
A method according to the invention makes it possible to make a check of the correct installation and operation of piston cooling nozzles (10) in a cold text prior to the final assembly of the engine by applying compressed air to each piston cooling nozzle (10) and directing the jet of compressed air emitted by the piston cooling nozzle (10) to be checked toward a surface pressure sensor (24). This makes it possible to record the position of the compressed air jet generated by the piston cooling nozzle (10) and preferably also the geometry of the jet. It is thereupon possible to draw conclusions concerning the proper operation and installation of the respectively checked piston cooling nozzle (10).
