What do you understand by fuel efficiency?

Fuel efficiency is the ability of a fuel or engine to produce maximum energy from minimum fuel consumption. Fuel is needed to run vehicles, machines, and generate power. Fuel efficiency measures how well a fuel is converted into useful energy. Higher fuel efficiency means more output with less fuel, reducing cost and pollution.

Factors Affecting Fuel Efficiency

• Type of Fuel: Petrol, diesel, and CNG have different efficiencies.
• Engine Condition: Well-maintained engines use less fuel.
• Driving Habits: Smooth driving improves mileage.
• Technology: Modern engines and hybrid systems increase efficiency.

Units of Fuel Efficiency

• Kilometers per liter (km/l) for vehicles.
• Energy output per unit of fuel in power plants.

Importance

1. Reduces fuel costs.
2. Decreases pollution and greenhouse gases.
3. Improves sustainability.
