How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is advanced Excel, Gas analyser with logging software, Innovate LogWorks, Fusion 360, in free, academic or evaluation versions. Tests are studied using real procedures for measuring system and control pressure with a gauge, fuel distribution testing between injectors, and mixture adjustment with a CO analyser. Assessment is continuous per module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain how continuous mechanical injection works.
Measure system, control and residual pressure.
Check the metering distributor and the fuel distribution between injectors.
Inspect the sensor plate, the throttle butterfly and the air intakes.
Adjust the mixture at idle using a gas analyser.
