Study Notes

Engine Basics

  • An engine is a machine that converts heat energy into mechanical energy.
  • It's a device that burns fuel to produce mechanical power, known as the combustion process.

Combustion Process

  • The engine generates power to move the vehicle by repeating four strokes:
    • Intake Stroke
    • Compression Stroke
    • Combustion Stroke
    • Exhaust Stroke

Identified Engine Parts

  • Intake Valve
  • Injector
  • Exhaust Valve
  • Combustion Chamber
