|---|---|
| KNOWLEDGE AND UNDERSTANDING THE COURSE GIVES THE STUDENTS THE PROPER EDUCATION AND EXPERTISE TO DEAL WITH TESTING AND CONTROL OF AUTOMOTIVE ENGINES. ATTENTION WILL BE GIVEN TO MODELING AND OPTIMIZATION TECHNIQUES. THE STUDENTS GET KNOWLEDGE OF METHODOLOGIES FOR EXPERIMENTAL DATA PROCESSING; INSTRUMENTS AND EQUIPMENTS OF ENGINE TEST BENCH; MEASUREMENT OF ENGINE PARAMETERS, PERFORMANCE AND EXHAUST EMISSIONS; DEVELOPMENT AND IDENTIFICATION OF SIMULATION MODELS ORIENTED TO ENGINE CONTROL; ENGINE CONTROL PROTOTYPING. ENGINEERING ANALYSIS IMPLEMENTATION AND USAGE OF NUMERICAL TOOLS FOR THE EXPERIMENTAL DATA ANALYSIS. POWERTRAIN SIMULATION IN STEADY STATE AND TRANSIENT OPERATION. ENGINEERING DESIGN DEVELOPMENT OF SIMULATION MODELS TO BE USED FOR ENGINE CONTROL DESIGN. SKILL TO SETUP THE MOST SUITABLE EXPERIMENTAL TEST FOR MODEL IDENTIFICATION/VALIDATION AND CONTROL PROTOTYPING. ENGINEERING PRACTICE IDENTIFY THE MOST SUITABLE INSTRUMENTS AND EXPERIMENTAL TESTS FOR ENGINE CONTROL DESIGN DEPENDING ON FINAL APPLICATION AND REQUIREMENTS. TRASVERSAL SKILLS - LEARNING SKILL TO APPLY THE GAINED EXPERTISE TO DIFFERENT CONTEXTS FROM THOSE PRESENTED DURING THE COURSE, WITH PARTICULAR REFERENCE TO EXPERIMENTAL AND MODELING TECHNIQUES, AND TO DEEPEN THE TOPICS USING MATERIALS OTHER THAN THOSE PROPOSED. TRASVERSAL SKILLS - INVESTIGATION ABILITY TO WORK AS PART OF A TEAM AND PERFORM ORAL PRESENTATION ON A TOPIC DEALING WITH TESTING AND CONTROL OF INTERNAL COMBUSTION ENGINES. |

| THE CLASS IS SCHEDULED IN 60 HOURS AMONG LECTURES, CLASSROOM EXERCISES WITH USE OF COMPUTERS AND MEASUREMENTS AT THE ENGINE TEST BENCH. THE TOPICS ARE: DESCRIPTION OF INSTRUMENTS AND FACILITIES OF THE ENGINE TEST BENCH (LESSON 6 H; LAB 2H): LAY-OUT OF ENGINE TEST BENCH. DYNAMOMETERS. ROLLING BENCH. ENGINE-DYNO COUPLING. INDICATING INSTRUMENTS. MEASUREMENT OF PRESSURE, O2, AIR AND FLOW RATE. HC, CO, NOX, CO2 GAS ANALYZER. EXPERIMENTAL MEASUREMENTS AT THE ENGINE TEST BENCH (LESSON 3H; EXERCISE 4H; LAB 5H): ENGINE CHARACTERISTIC CURVES (TORQUE, POWER, SPECIFIC FUEL CONSUMPTION). IN-CYLINDER PRESSURE. HEAT RELEASE RATE. EXHAUST EMISSIONS. ENGINE CONTROL SYSTEM (LESSON 8H; EXERCISE 2H): BASICS OF SYSTEMS THEORY APPLIED TO ICE. EVOLUTION OF ENGINE CONTROL. CONTROL PARAMETERS VS. CONSUMPTION AND EMISISONS. CONTROL OF AIR-FUEL RATIO (AFR) AND SPARK ADVANCE IN SPARK IGNITION (SI) ENGINES. MODEL BASED CONTROL AND CONTROL SYSTEM PROTOTYPING (LESSON 16H; EXERCISE 9H; LAB 5H): MEAN VALUE MODELS FOR AFR CONTROL IN SI ENGINES. PHENOMENOLOGICAL MODELS FOR COMBUSTION CONTROL IN COMPRESSION IGNITION (CI) ENGINES. MEAN VALUE MODELS FOR TURBOCHARGER AND EGR CONTROL. MODELING AND CONTROL OF GAS AFTER-TREATMENT SYSTEMS (TWC, DPF, SCR). SIMULATION ANALYSES IN MATLAB/SIMULINK AND CONTROL PROTOTYPING AT THE ENGINE TEST BENCH. |
| Teaching Methods | |
|---|---|
| THE CLASS IS SUPPLIED BY LECTURES, CLASSROOM EXERCISES BY INDIVIDUAL USE OF PC AND MEASUREMENTS AT THE ENGINE TEST BENCH. THE PRACTICAL PART INCLUDES EXAMPLES OF CALCULATIONS RELATED TO VARIOUS TOPICS, WITH THE IMPLEMENTATION IN MATLAB-SIMULINK ENVIRONMENT. IN LABORATORY THE STUDENTS APPLY EXPERIMENTAL METHODOLOGIES FOR THE CHARACTERIZATION OF AN INTERNAL COMBUSTION ENGINE AND FOR THE ENGINE CONTROL PROTOTYPING. |
| Verification of learning | |
|---|---|
| THE SUCCESSFUL ACHIEVEMENT OF COURSE OBJECTIVES WILL BE ASSESSED BY A NUMERICAL EXCERCISE ON PC FOLLOWED BY AN INTERVIEW. IN THE NUMERICAL EXCERSIZE THE STUDENT IS ASKED TO SOLVE AN ENGINEERING PROBLEM BASED ON THE ANALYSIS OF EXPERIMENTAL AND SIMULATED ENGINE DATA. IN THE INTERVIEW THE STUDENT IS REQUESTED TO DEFEND THE SOLUTION OF THE ENGINEERING PROBLEM AND TO PROVE A PROPER LEARNING OF THE THEORETICAL AND ANALYTICAL SUBJECTS PROVIDED DURING THE COURSE. PARTICULARLY THE STUDENT IS ASKED QUESTIONS RELATED TO THE EXPERIMENTAL CHARACTERIZATION AT THE ENGINE TEST BENCH AND THE IMPACT OF THE MAIN CONTROL VARIABLES ON ENGINE PERFORMANCE AS WELL AS NUMERICAL-EXPERIMENTAL METHODOLOGIES FOR THE ENGINE CONTROL SYSTEM DESIGN. THE MINIMUM MARK (18) IS GIVEN WHEN THE STUDENT PROVES POOR KNOWLEDGE OF THE EXPERIMENTAL TESTS AND OF THE RELATIONSHIPS BETWEEN CONTROL VARIABLES AND ENGINE PERFORMANCE. THE MAXIMUM MARK (30) IS GIVEN WHEN THE STUDENT PROVES TO BE HIGHLY CONFIDENT WITH THE EXPERIMENTAL METHODOLOGIES AND THE MODELING/EXPERIMENTAL TECHNIQUE FOR THE ENGINE CONTROL SYSTEM DESIGN. THE EXCELLENCE IS REACHED WHEN THE STUDENT EXHIBITS FULL KNOWLEDGE AND CLEAR EXPOSITION OF THE TOPICS TAUGHT IN THE CLASS AND WHEN CAN SUCCESSFULLY APPROACH AND SOLVED PROBLEMS DIFFERENT THAN THOSE SPECIFICALLY LEARNT IN THE CLASS. |
