Combustion is a crucial process that occurs in a car engine to generate power. It is an integral part of the internal combustion engine, which is the most common type of engine used in vehicles today. In this article, we will explore how combustion happens in a car engine and the components involved in this process.

Understanding Internal Combustion Engines
Internal combustion engines are classified into three main types: two-stroke engines, diesel engines, and four-stroke petrol engines. These engines rely on the combustion of fuel to create an explosion that moves the pistons down.
The Components Of Combustion
To achieve successful combustion in a car engine, three essential components are required:
- Fuel: This can be gasoline, diesel, or alternative fuels such as ethanol or natural gas. The fuel undergoes a chemical reaction with oxygen during combustion.
- Oxygen: Air is drawn into the engine through an intake system, providing the necessary oxygen for the combustion process.
- Ignition Source: An ignition system, typically using a spark plug for petrol engines or compression for diesel engines, provides the initial spark or heat required to ignite the fuel-air mixture and start the combustion process.

How Combustion Works in a Car Engine
Now let’s dive deeper into how combustion happens in a car engine:
Intake Stroke
The intake stroke is the first stage of the four-stroke cycle in a petrol engine. During this phase, the intake valve opens, and a mixture of fuel and air is drawn into the combustion chamber. In a diesel engine, only air is drawn into the chamber.
Compression Stroke
Next, the compression stroke occurs, where the piston moves upward, compressing the fuel-air mixture or air in the combustion chamber. This compression increases the temperature and pressure, preparing the mixture for combustion.
Power Stroke
The power stroke is the combustion phase where the spark plug ignites the fuel-air mixture or the compressed air in the diesel engine. The explosion created by the combustion pushes the piston back down, generating mechanical energy to power the vehicle.
Exhaust Stroke
The final stroke in the cycle is the exhaust stroke. During this phase, the exhaust valve opens, allowing the burned gases to leave the combustion chamber and exit through the exhaust system.
Components and Functions
Several key components work together to enable combustion in a car engine:
| Component | Function |
|---|---|
| Fuel System | Delivers fuel to the combustion chamber |
| Air Intake System | Provides oxygen for combustion by drawing in air |
| Ignition System | Produces a spark or heat to ignite the fuel-air mixture |
| Pistons | Moves up and down in the cylinder to create combustion |
| Camshaft | Controls the opening and closing of valves for intake and exhaust |
| Exhaust System | Channels the gas produced during combustion out of the engine |
