Free online courseFundamentals of Automotive Engineering: IC Engines, Powertrain, Brakes, Steering and Suspension

Course Description

Step beyond routine repairs and start understanding why a vehicle behaves the way it does. This free online course in automotive engineering fundamentals connects the physics, components, and system-level thinking that underpin modern cars and light vehicles. It is designed for learners who want to move from parts replacement to confident diagnosis, better decision-making, and clearer communication in a workshop or engineering context.

You will explore how internal combustion engines convert energy into motion, how engine design choices affect efficiency, performance, emissions, and drivability, and why real engines behave differently from ideal cycles. Along the way, you will build intuition for four-stroke and two-stroke operation, common engine limitations, mixture preparation, combustion behavior, and what causes phenomena such as knocking. This foundation helps you make sense of everyday issues like idle quality, power loss, fuel economy complaints, and emission-related faults.

The course then expands from the engine to the full powertrain. You will learn how torque is managed through clutches, transmissions, and gearing, and how these elements interact with vehicle speed and acceleration demands at the tyre-road interface. Rather than treating drivetrain components as isolated parts, you will view them as a coordinated system shaped by load transfer, traction limits, and gear matching decisions that influence acceleration, gradeability, and overall efficiency.

Safety-critical systems receive equal attention. You will develop a clear understanding of braking fundamentals, hydraulic and air brake architectures, why specific components exist, and how anti-lock braking strategies help preserve stability. From there, you will examine steering geometry and power steering behavior, and connect wheel alignment parameters to handling feel and tire wear patterns you can recognize in practice.

Suspension concepts round out the vehicle dynamics picture by linking ride comfort, control, and durability. You will see how dampers manage motion, why different suspension layouts require particular locating links, and how tyres and suspension work together as the vehicle’s only contact with the road. Quizzes throughout reinforce key ideas and help you check your understanding as you progress, making the learning practical and measurable.

By the end, you will have a coherent, end-to-end mental model of how engines, powertrain, brakes, steering, suspension, and tyres cooperate under real driving conditions—skills that translate directly into better troubleshooting, smarter maintenance choices, and stronger professional confidence in automotive repair and service.
