Course Title: Engine Technology
Course Description:
The Engine Technology course is a comprehensive program designed to equip learners with the theoretical knowledge and practical skills necessary to understand, maintain, diagnose, and repair internal combustion engines and related systems. This course provides an in-depth study of both gasoline (petrol) and diesel engines, covering their construction, operation, components, performance characteristics, and emissions control.
Through a blend of classroom instruction, laboratory sessions, and hands-on practical experience, students will learn the functioning of various engine systems, including fuel systems, ignition systems, lubrication, cooling, intake and exhaust systems. Emphasis is also placed on engine diagnostics, fault detection, service procedures, and adherence to safety and environmental standards.
The course aligns with current industry practices and introduces learners to modern engine technologies such as electronic fuel injection (EFI), turbocharging, engine control units (ECUs), hybrid systems, and alternative fuel engines.
Course Objectives:
By the end of the course, students should be able to:
Understand the principles of internal combustion engines (ICE).
Identify and describe engine components and their functions.
Perform routine engine maintenance and repairs.
Use diagnostic tools and procedures to troubleshoot engine faults.
