An internal combustion engine (ICE) is a device that converts chemical energy of fuel into mechanical work. On this page you will find an interactive simulation, explanations, and answers to common questions.

What is an internal combustion engine?
An internal combustion engine is a mechanism where fuel burns inside the chamber, creating pressure that moves the piston and produces mechanical energy.
Engine construction
- Piston:The moving part that transmits energy to the crankshaft.
- Combustion chamber:The place where fuel combustion takes place.
- Valves:Intake and exhaust for gases.
- Spark plug: Ignites fuel.
Engine cycles
- Intake: The intake valve opens, the piston moves down, draws in fuel.
- Compression:Valves closed, piston moves up, mixture is compressed.
- Combustion (power stroke):The spark plug ignites the fuel mixture, the piston moves down.
- Exhaust: The exhaust valve opens, the piston moves up, spent gases are expelled.
Advantages and Disadvantages of Internal Combustion Engines
- High power
- The possibility of using different types of fuel
- Emissions of harmful substances
- Noise and wear of parts
FAQ: Common Questions About Internal Combustion Engines
1. What are the main types of internal combustion engines?
Petrol, diesel, gas.
2. Why does an internal combustion engine require cooling?
Due to high combustion temperature to avoid overheating.
3. What is an engine stroke?
This is a cycle phase: intake, compression, power stroke, exhaust.
4. Why is the spark plug important?
It initiates the combustion of fuel.
5. How can the efficiency of an internal combustion engine be increased?
High-quality fuel, regular maintenance, modern technologies.
