Automotive Servicing NC 2 Engine repair - Rolando Escobar

A course in automotive engine repair typically covers the principles, tools, techniques, and procedures involved in diagnosing, maintaining, and repairing various types of internal combustion engines. Here’s a general summary of what such a course might include:

1. Introduction to Automotive Engines

  • Overview of engine types (e.g., gasoline, diesel, hybrid, electric).

  • Engine components and their functions (e.g., cylinder block, pistons, crankshaft, camshaft, valves, and timing mechanisms).

  • Basic principles of internal combustion engines.

2. Engine Diagnosis and Troubleshooting

  • Identifying common engine problems (e.g., misfires, overheating, low compression).

  • Diagnostic tools (e.g., OBD-II scanners, compression testers, leak-down testers).

  • Using service manuals and technical data to troubleshoot engine issues.

3. Engine Disassembly and Assembly

  • Procedures for safely disassembling and reassembling engines.

  • Inspection of engine parts for wear, damage, and proper function.

  • Replacing damaged or worn components like pistons, rings, bearings, valves, and seals.

4. Valvetrain and Timing

  • Understanding the role of the camshaft, valves, and timing in engine operation.

  • Adjusting valve timing and synchronizing components.

  • Repairing or replacing timing belts, chains, and related components.

5. Cooling and Lubrication Systems

  • How cooling systems (radiators, thermostats, water pumps) prevent engine overheating.

  • The importance of proper lubrication (oil pumps, filters, and oil change procedures).

  • Troubleshooting and repairing cooling and lubrication system failures.

6. Fuel and Ignition Systems

  • Understanding fuel delivery (fuel pumps, injectors, fuel lines).

  • Ignition system repair (spark plugs, coils, distributors, and ignition timing).

  • Diagnosing and repairing issues related to engine fuel and ignition systems.

7. Compression, Power, and Exhaust

  • The role of compression in engine performance.

  • Repairing and testing components like pistons, rings, and cylinder heads to maintain compression.

  • The importance of the exhaust system and troubleshooting exhaust leaks or blockages.

8. Engine Performance and Emission Control

  • Understanding engine performance and power production.

  • Diagnosing performance issues (e.g., lack of power, poor fuel economy).

  • Emission control systems (e.g., catalytic converters, EGR valves) and their repair.

9. Advanced Engine Technologies

  • Understanding newer engine technologies like turbocharging, supercharging, and hybrid systems.

  • Diagnosing and repairing modern engine control systems (ECU, sensors, actuators).

  • Working with high-performance or specialty engines.

10. Safety Practices and Tools

  • Proper safety measures when working with engines (e.g., personal protective equipment, lifting techniques).

  • Using hand tools, power tools, and diagnostic equipment safely and effectively.

11. Engine Performance Testing and Quality Control

  • Using dynometers, test equipment, and other tools to assess engine performance.

  • Conducting road tests and performance evaluations.

  • Ensuring repairs meet manufacturer specifications.

Conclusion:

The course provides students with practical, hands-on experience to repair and maintain automotive engines, covering everything from basic diagnostics to advanced repairs. By the end of the course, students should be prepared to work on a wide range of engine-related issues, from minor repairs to complex rebuilds, and be familiar with the latest automotive technologies.
