1. Internal Combustion Engine
in Thermal Power Engineering
A Presentation on IC Engine in Power
Generation

2. Introduction
• • Internal Combustion (IC) engines convert
fuel into mechanical energy.
• • Used in thermal power generation for
backup and small-scale electricity production.
• • Operates by burning fuel inside the engine
to produce power.

3. Types of Internal Combustion
Engines
• • Spark Ignition (SI) Engine - Uses petrol,
operates with spark plug.
• • Compression Ignition (CI) Engine - Uses
diesel, ignites fuel by compression.
• • Two-Stroke Engine - Completes power cycle
in two strokes.
• • Four-Stroke Engine - Completes power cycle
in four strokes.

4. Working of Internal Combustion
Engine
• • Intake Stroke - Air-fuel mixture enters the
cylinder.
• • Compression Stroke - The mixture is
compressed.
• • Power Stroke - Fuel ignites, generating
power.
• • Exhaust Stroke - Burnt gases are expelled.

5. Applications in Power Engineering
• • Used in small-scale power generation.
• • Acts as a backup power source in thermal
plants.
• • Employed in remote and off-grid areas.
• • Provides energy for auxiliary systems in
power plants.
