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).
Claims24
A method for checking nozzles of internal-combustion engines, with the nozzles being installed and checked for their correct installation and/or operation prior to the complete assembly of the respective internal-combustion engine, wherein each nozzle is checked with a jet of fluid medium directed toward at least one pressure sensor, wherein the fluid medium is compressed air.
(canceled)
A method for checking nozzles of internal-combustion engines, with the nozzles being installed and checked for their correct installation and/or operation prior to the complete assembly of the respective internal-combustion engine, wherein each nozzle is checked with a let of fluid medium directed toward at least one pressure sensor;
- and, for the checking of piston cooling nozzles (10), at least one pressure sensor is detachably affixed above a respective cylinder bore (13) on a side of the engine block (14) facing a cylinder head (28).
A method for checking nozzles of internal-combustion engines, with the nozzles being installed and checked for their correct installation and/or operation prior to the complete assembly of the respective internal-combustion engine, wherein each nozzle is checked with a let of fluid medium directed toward at least one pressure sensor and, for the checking of injection nozzles (26), the at least one pressure sensor is detachably arranged on a bearing side of a cylinder head (28) on an engine block (14) in front of a respective combustion chamber (31) at the cylinder head (28).
