An internal combustion engine consists of several major parts, each playing a crucial role in power generation. With VR, learners can explore 3D models of engines, view exploded diagrams, and interact with components to understand their structure and function.

Main parts of an engine include:

• Cylinder – The chamber where combustion occurs.
  
• Piston – Moves up and down to transfer force from expanding gases.
  
• Connecting Rod – Connects piston to crankshaft, transmitting motion.
  
• Crankshaft – Converts reciprocating motion of piston into rotary motion.
  
• Valves (Inlet & Exhaust) – Control entry of air-fuel mixture and exit of exhaust gases.
  
• Camshaft – Operates valves in synchronization with crankshaft.
  
• Spark Plug / Fuel Injector – Ignites fuel-air mixture (petrol) or injects fuel (diesel).
  
• Flywheel – Maintains rotational inertia for smooth running.
  
  

Advantages of using VR for engine study:

• Safe and cost-effective (no need to dismantle real engines).
  
• Interactive 3D visualization of hidden/complex parts.
  
• Ability to simulate working cycles dynamically.
  
• Repeatable learning without physical wear and tear.
