General
  • English
  • Every other autumn semester
Aim
  • The course gives an overview and understanding of the control system of a modern internal combustion engine. The course also provides an understanding of the models that are used for engine control system development.
Contents
  • Introduction to engine control systems: tasks, structure, future engine control systems.
    Mean value engine models: Cause and effect relations in engine systems, reservoirs and flows, cycle resolved models and why they are often ill suited for engine control, mean value engine models, air flow, fuel models, efficiencies.
    Engine control: Air/fuel ratio control for SI engines, cylinder pressure based control of advanced engine concepts.
    Cylinder pressure based parameter estimation: Estimation of pressure sensor offset, estimation of TDC offset, heat release computation.
Knowledge and Understanding
  • For a passing grade the doctoral student must
  • Understand the tasks and structure of a modern engine control system.
    Understand the difference between mean value and cycle-resolved models.
    Understand the basic components of a mean value model.
    Understand how air flow is modelled in a mean value model.
    Understand how fuel flow is modelled in a mean value model.
    Understand how efficiencies are modelled in a mean value model.
    Understand how the air/fuel ratio control works on an SI engine.
    Understand how cylinder pressure measurement can be used for feedback control of advanced engine concepts.
    Understand how cylinder pressure sensor offset can be estimated through a polytropic fit.
    Understand how TDC offset can be estimated from motored cylinder pressure measurements.
    Understand how heat release from combustion can be computed based on cylinder pressure measurements.
Competences and Skills
  • For a passing grade the doctoral student must
  • Be able to build a mean value model of the air flow, fuel flow and power generation of an SI engine.
    Be able to estimate pressure sensor offset from given motored cylinder pressure data.
    Be able to estimate TDC-offset from given motored cylinder pressure data.
    Be able to compute heat release from given cylinder pressure data with and without combustion.
Judgement and Approach
  • For a passing grade the doctoral student must
  • Be able to judge which time scales are important to model in a given engine control system.
    Be able to select a suitable model class depending on which part of the engine should be controlled.
Types of Instruction
  • Lectures
  • Exercises
  • Due to external participation the course is normally given as a blocked course starting with two full days of lectures followed by some weeks of self studies with exercises. The course ends with two full days of lectures and an oral exam.
Examination Formats
  • Oral exam
  • Written assignments
  • Failed, pass
Admission Requirements
  • Introduction to combustion engines (MVK093) or similar.
Assumed Prior Knowledge
  • Basic knowledge of automatic control.
Selection Criteria
  • Priority for applicants who work with engine control related research projects.
