FAQs on Fuel and Fuel Efficiency - Combustion and Flame, Class 8 Science Video Lecture

1. What is fuel efficiency and why is it important?

Ans. Fuel efficiency refers to the measure of how effectively a fuel can be used to produce energy. It is important because higher fuel efficiency means that lesser fuel is consumed to generate the same amount of energy, leading to cost savings and reduced environmental impact.

2. How is fuel efficiency measured?

Ans. Fuel efficiency is usually measured in terms of mileage or kilometers per liter (km/l) for vehicles and liters per hour (l/hr) for machinery. It is calculated by dividing the distance traveled by the amount of fuel consumed.

3. What factors affect fuel efficiency?

Ans. Several factors can affect fuel efficiency, including the type and quality of fuel used, the design and condition of the engine, driving habits such as speed and acceleration, vehicle maintenance, and external factors like road conditions and air resistance.

4. How can fuel efficiency be improved?

Ans. Fuel efficiency can be improved by adopting certain practices such as maintaining a steady speed, avoiding excessive idling, reducing unnecessary weight in vehicles, regular maintenance of engines and tires, using high-quality fuel, and employing technologies like hybrid or electric vehicles.

5. What are the benefits of using fuel-efficient vehicles?

Ans. Using fuel-efficient vehicles offers several benefits, including reduced fuel costs, lower carbon dioxide emissions, less dependence on fossil fuels, and a positive contribution towards environmental conservation and sustainability. Additionally, fuel-efficient vehicles often have advanced features and technologies that enhance overall performance and driving experience.
