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

Course Description

Fundamentals of Automotive Engineering: IC Engines, Powertrain, Brakes, Steering and Suspension is a free online course from NPTEL designed for learners who want a solid, practical understanding of how core vehicle systems work and how their performance is analyzed. Positioned within Professional Skills and the Automotive Repair subcategory, it focuses on the engineering principles that connect engine operation to drivetrain delivery, vehicle control, and ride comfort.

The course builds strong foundations in internal combustion engines by explaining key components, four-stroke and two-stroke operation, and the thermodynamic cycles used to model real engines, including Otto, Diesel and dual cycles. It also explores how performance is evaluated and improved through concepts such as supercharging, along with common combustion challenges such as knocking in spark-ignition engines and combustion behavior in compression-ignition engines.

Fuel delivery and mixture preparation are covered with clear treatment of fuel introduction systems and carburetor analysis, followed by an applied look at engine emissions and the systems used to reduce environmental impact. From there, the course connects engine output to the road through powertrain fundamentals, clutch operation, transmission concepts, matching strategies, and step-by-step approaches to powertrain analysis.

Vehicle safety and handling are addressed through braking systems, including disc brakes, hydraulic and air braking, and anti-lock braking systems, supported by braking analysis methods. Steering topics span manual and power steering, plus wheel alignment principles that influence stability and tire wear. Finally, suspension is introduced from first principles with shock absorbers, dependent suspension layouts, and suspension analysis, alongside coverage of tyres and an introductory look at electric vehicle basics.

This course is a strong fit for students, technicians, and automotive enthusiasts seeking a structured pathway from fundamentals to system-level understanding across engines, driveline, brakes, steering, and suspension.
