Advanced Engines in Hybrid Electric Vehicles (HEVs)


Course Description

AUTO 242 AUTOMOTIVE ENGINE PERFORMANCE Covers the practices found in current automotive performance, diagnosis and repair businesses. Diagnosis performed on the basis of an approved procedure and problem(s) then corrected on the basis of this procedure’s outcomes. Fuel, ignition, computer and emission control systems are studied. Inspection, service and maintenance procedures of these systems are performed.

Learning Outcomes

Upon successful completion of the course, a student should be able to:

1. Apply shop safety procedures.
2. Demonstrate the ability to use various automotive repair and specification manuals and software.
3. Define the various terms used in the engine performance industry.
4. Identify names of the components of the various types of fuel, ignition, computer, emission control, lubrication, cooling, starting and charging systems.
5. Demonstrate the ability to use various specialty tools and equipment utilized in the diagnosis and repair of automotive performance.
6. Discuss vehicle problem(s) with vehicle owner and/or instructor and test drive to determine needed service and/or repairs.
7. Prepare a customer service order estimating the costs of vehicle service and/or repairs including the costs of parts and labor (using the Mitchell Parts and Labor Estimating software) and compare allotted time to actual time spent.
8. Write a diagnostic and service report containing procedure(s) followed, findings upon the conclusion of t he test(s) and service needed.
9. Inspect vehicle for fuel, oil, coolant and other fluid leaks locating source of leak and type of repair(s) needed.
10. Differentiate between abnormal engine noises and vibrations, locating the cause of each.
11. Examine and determine cause of unusual exhaust gas color, odor and sound.
12. Perform diagnostic tests on engine mechanical, electrical, electronic, fuel, ignition and emission control systems with the use of an oscilloscope, 4 or 5 gas analyzer and engine (performance) diagnostic equipment.
13. Retrieve and clear diagnostic trouble codes (on OBD I computer systems) in accordance with manufacturer’s recommended procedures.
14. Interpret diagnostic trouble codes and computer data utilizing appropriate scan tools and diagnostic charts.
15. Diagnose emission and drivability concerns resulting from failure of computerized engine controls, with and/or without diagnostic trouble codes.
16. Inspect and test computerized engine control systems including control modules, sensors, actuators and circuits (power and ground) making necessary repairs and/or adjustments.
17. Locate and interpret vehicle identification numbers (VIN) and (engine) calibration/emission decals.
18. Practice recommended precautions when handling static sensitive devices.
19. Diagnose no- starting, drivability and emission concerns on vehicles with distributor- type ignition (DI) systems.
20. Inspect and test primary and secondary ignition system circuit wiring and components including ignition control modules, coils, triggering devices, spark plug cables, cap and rotor.
21. Inspect and test distributor for proper advance/retard, adjusting ignition timing (where applicable) in accordance with manufacturer’s recommended procedures.
22. Diagnose and repair drivability and performance problems on vehicles with computer controlled (feedback) carburetor- type fuel delivery systems.
23. Inspect, test and service or replace fuel system components including fuel tank, fuel cap, fuel lines, fittings, hoses, filters and sending units.
24. Perform fuel pump inspection and tests on mechanical and electrical fuel pumps and pump control systems including pressure regulation systems and components.
25. Test and adjust (where applicable) engine idle speed, fuel mixture and cold enrichment system and components.
26. Service throttle body assemblies and components including mounting plate(s), air induction, filtration system, manifold(s) and gaskets.
27. Diagnose emission and drivability problems resulting from failure of the positive crankcase ventilation (PCV), exhaust gas recirculation (EGR), secondary air injection, catalytic converter, intake air temperature control, early fuel evaporation control and evaporative emissions control systems.
28. Inspect and test various components (and circuits where applicable) of the positive crankcase ventilation (PCV), exhaust gas recirculation (EGR), secondary air injection, catalytic converter, intake air temperature control, early fuel evaporation control and evaporative emissions control systems.
29. Verify correct camshaft timing and perform actions needed for correcting. (VVT and non- VVT controls on standard vehicles and HEVs)
30. Demonstrate understanding of variations of HEV power train arrangement
31. Demonstrate proper safety precautions when servicing HEV systems
32. Isolate HV battery from HEV electronics
33. Inspect HEV PPE and tools for failure
33. Diagnose HEV Insulation Leak failure
