Gasoline Engine Management

3 days MOT/CME-E
  • Engineers and technical staff from design and testing departments wishing to know the main components and functions of the SI engine management.
  • This course provides a deeper knowledge on spark ignition engines: the different functions related to air supply, fuel supply and combustion; the sensors and the actuators related to each of these functions and how to use them.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • have an overview of the gasoline engine control system,
  • have the necessary elements to diagnose some simple failure modes,
  • talk to specialists to understand and make control strategies evolve.
  • No prerequisites for this course.
Ways and means
  • Interactive training with real life examples.
