Gas prices continue to rise, with no end in sight. This trend reinforces the need for all people, buying more fuel efficient cars. After a car with good fuel economy is not only helpful to save money, but it is also an essential part of repairing the environment. The official definition of fuel is how much gas is needed to move a certain distance. In the United States in terms of fuel economy in miles per gallon, while the rest of the world, it is usually calculated in liters per hundred kilometers. These measurement systems are very different, a greater number in the U.S. system is optimal, while a lower number is desired in the metric system (the lower the number, the lower the amount of fuel required to travel a hundred kilometers) . Governments are taking notice of the importance of fuel consumption and laying down guidelines which will regulate efficiency in the future. The European Union has decided that from 2012 to gasoline cars must be at least a 47mpg rating, and diesel vehicles at least a 52mpg rating. The United States currently taxes vehicles that are not in environmental standards as a means to discourage their production. These taxes and penalties are likely to increase over the next few years. Engineers are constantly working to find ways to increase the fuel efficiency of vehicles. Several factors affect fuel economy, so it produce a matter of changing these factors, better efficiency. The weight of a car is one of the biggest factors in fuel economy, so that designers are always trying to make cars lighter. This can be done by replacing traditional materials such as iron, with alternative options like carbon fiber. Wind resistance and drag require cars exert energy to overcome them, so that vehicles are intended, these factors slightly better fuel consumption experience. Anything that increases or saving energy can be an advantage. For example, switching off the engine while the car is stopped energy savings. Improving the efficiency of engine combustion is a critical factor. Most engines utilize only 10-20% of the energy emitted from the combustion of fuel, the rest is lost to heat and other forms of energy. Fuel cells are so desirable because up to 80% of the energy produced can be used directly. Various types of internal combustion engines, such as lean burn and HCCI combustion are being tested to determine which method is most efficient. Average consumers can play their part in the fuel economy of their vehicles. Fuel efficiency products are popular on the market currently, but not most of them really improve efficiency in all areas. Simple things, like hold the air pressure in the tires up, and slowly accelerates and slows down, a vehicle to extend the rating to an acceptable level. Hybrid cars are currently the best option for those who want the speed and low fuel consumption. These models combine electrical and gasoline engine components to something that does not create such an electric car is not at all the feeling. Hybrid vehicles to recover wasted energy during the braking time to conclude from gasoline power during idle times, and get gas and electricity while reducing the total quantity of spent fuels. All these factors together result in fuel ratings of over 50mpg, and lower emissions.
