Abstract

Within the scope of Euro 7 emission norms, new types of injectors and engine parts are produced in order to reduce fuel consumption to minimum levels in diesel engine vehicles and accordingly to reduce emission rates. The complex geometry, high precision and high strength required by the nozzle design that will meet the requirements of the aforementioned norms have made the produc-tion of the required nozzles on existing production platforms difficult and the manufacturers have faced serious problems. Manufacturing companies needed the development of tooling systems suitable for the existing production platform rather than investing in the high-cost machine park. In this study, it is aimed to increase the tool life by choosing the most appropriate machining parameters for the surface quality obtained in the production of a single nozzle, which is de-signed and manufactured using six different tools, which will enable the use of existing machining platforms in the production of Euro 7 nozzles. The average surface roughness value on the nozzle surfaces was determined as Ra = 0.34 µm and it was observed that the desired surface quality was achieved. Performance tests have shown that the design and production activities are successful and that the developed tooling system can be used for the production of Euro 7 Nozzle from existing production platforms.
