인천운전연수 Fuel efficiency is a key factor to consider when purchasing a vehicle. A vehicle with better fuel efficiency will cost less to manage over time, since it goes farther on a given amount of fuel.
There are several ways to improve your car’s fuel efficiency. These include: removing excess weight, changing driving habits and using multi-speed transmissions.
As the energy cost of gasoline has risen, improved fuel efficiency has become an important vehicle design goal. Transportation is a significant contributor to global greenhouse gas emissions, and increased fuel efficiency can make a substantial impact on the overall climate change problem. Consumers are encouraged to purchase more fuel efficient vehicles through a variety of private strategies and public policies. In the United States, for example, automobile manufacturers must display a specific fuel economy rating on a sticker known as a Monroney sticker.
Engine and drive train efficiency improvements are among the most important factors in improving fuel consumption. Manufacturers use a variety of technologies to reduce friction and other energy losses in engines, transmissions and drive trains. These include using computerized controls, adjusting the amount of air being pulled into the engine and optimizing cylinder firing to produce more power with less fuel. Manufacturers also use lightweight materials, such as carbon fiber and lighter metals, to reduce the weight of motor vehicles without sacrificing strength or durability.
Lighter vehicles are more fuel efficient than heavier ones, because the engine does not have to work as hard to move the car. In addition, the vehicles often have better driving dynamics, with agile accelerations and shorter braking distances.

Fuel efficiency depends on the type of fuel used and engine technology. Cars, trucks and other on-road motor vehicles consume 60 percent of the United States’ oil and produce 25 percent of its greenhouse gas emissions, according to the U.S. Department of Energy, the MIT School of Engineering and HowStuffWorks. Using alternative fuels and advanced engines reduces consumption and pollution.
New fuels include biodiesel, electricity, ethanol, natural gas and propane. These may be used in dedicated systems or blended with traditional gasoline to improve fuel economy. Hydrogen and sustainable aviation fuel also promise to improve efficiency. They are made by converting carbon-rich molecules like CO2 into more complex, energy-dense fuels through electrolyzers or other chemical processes.
Ethanol is a popular renewable fuel, made from vegetable oils and animal fats. It can be blended with gasoline to make a blend called e10. Electricity, powered by a battery system that stores electrical energy, is another alternative. Hybrid configurations combine internal combustion engines with electric motors to save fuel and cut emissions.
New fuels can also be created from renewable materials such as plant waste and algae. Some of these are being researched by Lawrence Livermore National Laboratory’s Carbon Capture and Sequestration project, which involves removing carbon from coal-powered power plants and storing it in underground reservoirs. In addition, researchers are developing technologies to turn carbon into a useful fuel for cars.
Reducing motor vehicle weight
For decades, auto manufacturers were able to improve vehicle fuel efficiency with new engines and advanced technologies that did not require reducing vehicle weight. But now, with federally mandated MPG targets in place, the focus has shifted to shedding pounds. This effort, called lightweighting or lightweighting, is not just about improving MPG numbers – it can also help reduce greenhouse gas emissions (GHGs) from manufacturing and driving.
Reducing vehicle weight can be accomplished through reducing the size of vehicles (downsizing) or by changing the material composition of cars. For example, replacing mild steel with high-strength or aluminum alloys can result in a significant weight reduction.
Regardless of the method used to decrease vehicle weight, a more compact vehicle will consume less fuel. Similarly, the weight of accessories and equipment can be reduced by using smaller or more efficient alternatives.
The most important factor in determining how much fuel a vehicle consumes is the distance it travels per unit volume of fuel, usually expressed as kilometres per litre or miles per gallon. It is this value that most consumers are concerned about when shopping for a car or truck. The lower this number is, the better a vehicle’s fuel economy is. To achieve this, engineers seek to minimize energy consumption without sacrificing comfort or safety. As we have seen, one of the best ways to do this is by reducing the vehicle’s weight.
Changing driving habits
With the price of fuel constantly on the rise, every little bit helps when it comes to improving your car’s efficiency. A few simple changes to your driving habits can make a big difference in how much you need to refuel, and will also help the environment.
Some easy ways to improve your fuel economy include avoiding excessive braking and acceleration, and minimizing drive time by planning ahead and avoiding rush hour traffic whenever possible. It’s also important to keep your engine in the best possible condition, as a rough running engine requires more energy and is less efficient.
Another important factor is reducing the amount of weight in your vehicle. A vehicle that has to carry extra cargo around will consume more fuel and have a negative impact on its overall efficiency. Avoid unnecessary luggage and unneeded equipment, as every 100 pounds adds about 1% to your fuel consumption.
Anecdotal evidence suggests that as gas prices have risen, drivers are starting to change their habits in an effort to cut back on their need for fuel. Some are even changing their road trips to lessen the distances traveled, a practice that will save both money and gasoline. Other common changes being made are driving less, combining errands, and reducing shopping or dining out. These changes not only save drivers money on fuel but also benefit the environment by lowering the country’s dependence on oil and decreasing its pollution levels.
