The large marine engines of the world\u2019s cargo ships are an important focus area in the maritime industry\u2019s efforts to become more sustainable. This also applies to the individual parts of the engine, which must be continuously optimized in order to meet the future requirements of a lower and greener fuel consumption.<\/p>\n\n\n\n
An essential component in this context is the injection nozzle, which injects fuel into the engine, where it is mixed with oxygen to ensure optimal combustion.<\/p>\n\n\n\n
In a collaborative project between DTU and MAN Energy Solutions, a young researcher has conducted an extensive investigation into whether it could be advantageous to make a 3D-printed injection nozzle, writes the Technical University of Denmark (DTU) in a press release<\/a>.<\/p>\n\n\n\n \u201cAt MAN Energy Solutions, we\u2019ve long been aware that 3D-printed metal can provide us with some opportunities to design important parts of our ship engines that were not previously possible. This made a collaboration with DTU on exploring the potential an obvious choice,\u201d says Peter Hagen, mechanical engineer at MAN Energy Solutions.<\/p>\n\n\n\n Postdoc Thomas Dahmen from DTU Mechanical Engineering conducted the study, where he began by carrying out a Quality Deployment Function analysis for 3D printing. 3D-QFD is an analysis model used to provide an overview of the value 3D printing can add to a product as a whole.<\/p>\n\n\n\n \u201cBy applying the model and combining it with technical insight into both 3D printing methods and fuel injection, I have created a modular kit of how 3D-printed nozzles can be designed to increase engine performance and product lifetime,\u201d says Thomas Dahmen.<\/p>\n\n\n\n The improvement of the injection nozzle was based on the fact that a better fuel flow could be achieved with a slightly different\u2014and more curved\u2014design. In this way, the new nozzle design contributes to improved engine combustion. Initial trials also suggest that the nozzle could potentially help reduce NOx emissions from the engine, but further studies will be required to demonstrate such an effect.<\/p>\n\n\n\n The new 3D-printed injection nozzle showed such promising results in the DTU laboratory that it was subsequently tested on MAN Energy Solutions\u2019 full-scale test engine at Research Centre Copenhagen.<\/p>\n\n\n\n \u201cThe test went well, and we look forward to doing a long-run test next,\u201d says Peter Hagen and continues:<\/p>\n\n\n\n \u201cThomas\u2019 thorough investigation has given us a fantastic basis for moving forward with 3D printing of metal components for marine engines. I\u2019m quite sure we\u2019ll see them in real engines soon.\u201d<\/p>\n\n\n\n Peter Hagen stresses that the collaboration with DTU on continued optimization of marine engines will continue in the future.<\/p>\n\n\n\n In his comprehensive analysis, in addition to looking at the nozzle design, Thomas Dahmen also compared the pros and cons of two different 3D printing techniques\u2014Laser Powder Bed Fusion and Binder Jetting\u2014 in combination with using different types of materials for the nozzles.<\/p>\n\n\n\n \u201cThis part of the analyses highlighted the suitability of Binder Jetting for intricate flow-related nozzle features and special high-temperature materials which would be impossible to realize with other manufacturing processes\u201d says Thomas Dahmen.<\/p>\n\n\n\n Also interesting: <\/strong><\/em>3D printing makes inroads into the construction industry<\/a><\/p>\n","protected":false},"author":2084,"featured_media":346134,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[8553],"tags":[7738,56363,126463,56651,78478,56372],"location":[56342],"internal_archives":[],"class_list":["post-346133","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-digital","tag-3d-printing-en","tag-dtu","tag-green-fuels","tag-hybrid-engines","tag-man-energy-solutions","tag-technical-university-of-denmark","location-denmark"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/01\/JcPIUFND-MAN-ES_RCC-1_PEOPLE_EGL5234_web-1.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on January 12, 2022","modified":"Updated on January 12, 2022"},"absolute_dates_time":{"created":"Posted on January 12, 2022 12:00 pm","modified":"Updated on January 12, 2022 12:00 pm"},"featured_img_caption":"\u00a9 MAN Energy Solutions","tax_additional":{"category":{"linked":["Digital<\/a>"],"unlinked":["Digital<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["3D printing<\/a>","DTU<\/a>","green fuels<\/a>","hybrid engines<\/a>","MAN Energy Solutions<\/a>","Technical University of Denmark<\/a>"],"unlinked":["3D printing<\/span>","DTU<\/span>","green fuels<\/span>","hybrid engines<\/span>","MAN Energy Solutions<\/span>","Technical University of Denmark<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":[],"unlinked":[],"slug":"post_translations","name":""},"location":{"linked":["Denmark<\/a>"],"unlinked":["Denmark<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/346133","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/346134"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=346133"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=346133"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=346133"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=346133"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=346133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Broad analysis of 3D printing\u2019s possibilities<\/strong><\/h3>\n\n\n\n
