🌍 What Petrol Is

🌍 What Petrol Is

Petrol is a mixture of hydrocarbons derived from crude oil. During the refining process, crude oil is separated into components based on their boiling points, and petrol is one of the lighter fractions.

⚙️ How Petrol Works in Engines

Petrol engines use a spark-ignition system:
1. Air and petrol mix inside the engine.
2. A spark plug ignites the mixture.
3. The explosive combustion pushes the piston.
4. This motion ultimately powers the vehicle.

🧪 Properties of Petrol
• Highly flammable
• Low viscosity (flows easily)
• Evaporates quickly
• Has a specific octane rating, which measures resistance to engine knocking

📌 Uses of Petrol
• Fuel for cars, motorcycles, scooters
• Small machines: lawnmowers, generators
• Used as a solvent in some industrial processes

🏭 Environmental Impact

Petrol combustion releases:
• Carbon dioxide (CO₂) → contributes to climate change
• Carbon monoxide (CO)
• Nitrogen oxides (NOx)
• Particulate matter

Because of this, many countries are shifting toward electric vehicles (EVs) and cleaner fuels.

💰 Petrol Pricing

Prices vary by country and depend on:
• Global crude oil prices
• Taxes and government policies
