Content:

• Emphasis on practical diagnostics on a real diesel vehicle, providing the student with the knowledge to make diagnoses

on any diesel cycle vehicle.

• Applications and operation of sensor elements in the diesel cycle.

• Interpretation of electrical schematics during practical tests.

• Common Rail system operation analysis comprising the different injection cycles: pre-injection,

main injection and post injection.

• Presentation of Diesel aftertreatment systems.

• Practical vehicle tests available.

Prerequisites:

• Basic knowledge of diesel electrical and mechanical quantities.

Duration: 12 hours.

Programming:
