Fuel Efficiency: Definition and Properties

Fuel Efficiency

Fuel is an important source of energy. We use fuel in our daily lives for different activities such as petrol and diesel to drive vehicles, LPG for cooking, refined oil to fly aeroplanes, coal, and burning wood that provides fire and warmth in the form of energy. All fuels burn to produce energy, but not every fuel burns efficiently. The fuel efficiency of a vehicle is calculated by kilometres or litter metres.

The fuel efficiency is calculated based on its caloric value. This calorific value is defined as the amount of energy produced during the complete combustion of the fuel. The fuel is mainly a pathway containing carbon, which releases a significant amount of thermal energy during combustion. It is used for different domestic and industrial purposes.

Fuel efficiency

Energy cannot be created or destroyed; all energy can only be transferred. It is only with the help of the thermal energy supplied to them that they convert the chemical energy of the fuel into kinetic energy. The efficiency with which fuel converts energy in this way is called fuel efficiency.

Fuel efficiency is measured by the amount of heat produced by 1 kg of fuel during combustion. This is known as the calorific value of fuel. The unit for measuring fuel efficiency is known as kilojoules. Let’s take a look at what are the features of an efficient fuel.

Fuel Economy – This is the distance travelled according to the unit volume of the fuel used in a vehicle. The longer a vehicle runs in an infinite amount of fuel, the better its fuel economy. It also depends on the engine’s performance. Improved engines make the combustion of fuel more efficient.

Efficient fuel must be eco-friendly – this means that harmful gases should not be produced as side products when burned.

A good fuel must have a low combustion temperature – which means it should catch fire easily without wasting too much energy.

Applications of fuel efficiency

Fuel efficiency is a form of thermal efficiency, i.e., it is an anomaly of effort as a result of a process that converts the chemical potential energy contained in a carrier into kinetic energy or combustion. The overall fuel efficiency may vary from device to device. And this spectrum of variation is often depicted as a continuous energy profile.

Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially in industries that deal with combustion, such as fossil fuel power plants or ammonia production during the Haber process.

In the context of transportation, fuel economy is defined as the energy efficiency of a particular vehicle, which is provided by a unit of consumption as a proportion of the distance travelled by a unit of fuel. It depends on several factors, including engine efficiency, transmission design, and tire design. Fuel efficiency provides significant environmental benefits. Therefore, fuel-efficient driving strategies use less fuel and reduce greenhouse gas emissions. This helps in reducing the cost of travel and loss of energy.
