What is Fuel Efficiency?
Fuel efficiency is a measure of how efficiently a vehicle uses fuel. It is often expressed as miles per gallon (mpg) in the United States and kilometers per liter (kpl) in other countries. A higher fuel efficiency rating means that a vehicle can travel further on less fuel. Fuel efficiency is important for several reasons. First, it can save consumers money on fuel costs. Second, it can help to reduce air pollution. Third, it can help to conserve natural resources.
There are several factors that can affect fuel efficiency, including the type of fuel used, the size and weight of the vehicle, the driving conditions, and the driver’s habits. For example, a vehicle that uses gasoline will typically have lower fuel efficiency than a vehicle that uses diesel fuel. A larger and heavier vehicle will also have lower fuel efficiency than a smaller and lighter vehicle. Driving in stop-and-go traffic or at high speeds will also reduce fuel efficiency.
What is a Fuel? and Effects of Burning Fuels – NCERT Class-8 Notes
What is a Fuel? and Fuel Efficiency Burning of Fuels Leads to Harmful Products- Class 8 NCERT Revision Notes: Fuel is a substance that releases energy when burned. Fuels are used to power vehicles, generate electricity, and heat homes and businesses. There are many different types of fuels, including fossil fuels, renewable fuels, and nuclear fuels. Fuel efficiency is a measure of how efficiently a fuel is used. It is the ratio of the amount of energy produced by a fuel to the amount of energy that is consumed. Fuel efficiency is important because it can help to reduce fuel costs and emissions.
