Learning Objectives

  • Upon completion of the course, participants will be able to understand:
  • drivability from an engineering perspective,
  • how engine management functions and its impact on drivability,
  • the physics and the parameters used in the engine that improves drivability,
  • the vehicle reactions that cause customer drivability concerns for the engine and vehicle systems and interfaces.
