How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetable: 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 Bosch ESI[tronic], advanced Excel, pump bench management software, opacimeter software, in free, academic or evaluation versions. Tests are studied using real procedures for timing in-line and rotary pumps, injector calibration and spray tests, and measurement of smoke opacity. Assessment is continuous by module, plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain how in-line and rotary mechanical injection pumps work.
Carry out the timing and setting of the pump on the engine.
Check and calibrate injectors and nozzles.
Diagnose starting, power and smoke faults of mechanical origin.
Plan the repair and bench calibration of the pump.
