How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so it can be combined with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Fusion 360, SolidWorks, Microsoft Excel and SuperFlow WinDyn, in free, academic or evaluation versions. Testing is studied through real procedures for the metrology and rebuilding of vintage engines, re-metalling white metal bearings and dyno testing rebuilt engines. Assessment is continuous by module, plus the final integrated project.
Standards covered: ISO 286-1, ISO 1101, EN 228, FIVA Turin Charter, FIVA Technical Code, SAE J1349.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
