Natural gas prices continue to rise, no end in sight. This trend will further highlight the need for humanity to get more fuel efficiency. Have a good fuel economy car is not only useful in order to save money, but also an integral part of environmental improvement.
In the fuel economy of a formal definition of natural gas needed to travel a certain distance. In the U.S., fuel economy is a measure of miles per gallon, while the rest of the world, mainly liters per 100 kilometers. These measurement systems are very different in the United States increase in the number of systems are optimal, there is a small part in the metric system (the smaller the number, the lower the fuel needed to travel 100 kilometers of the quantity).
Governments are taking the importance of fuel economy, noting the establishment of guidelines for the future efficiency. The European Union has decided that from 2012, petrol cars must have at least a 47mpg rating, diesel vehicles must have at least 1 52mpg rating. Currently, the U.S. car tax, non-compliance, as their production methods to inhibit environmental standards. These taxes and penalties, are expected to increase significantly in the coming years.
Engineers have been working to find ways to increase vehicle fuel efficiency. Several factors affect fuel economy, so it is a modified factor, resulting in better efficiency. In the car's fuel economy, one of the biggest factors that weight, so engineers are always trying to make cars lighter.
This can replace the conventional materials such as iron, carbon fiber and other alternatives. Wind resistance, drag car takes energy to overcome, so that vehicle design experience, these factors are minimal fuel savings. All of these can increase or save energy is beneficial. For example, turn off the car parked in energy conservation.
To improve the efficiency of internal combustion engine is a key factor. Most of the engine is only 10-20 to use the energy released by fuel combustion% and the remaining by heat and other forms of energy loss. Fuel cell is less than ideal, because up to 80% of its energy produced can be used directly. Different types of combustion, such as the lean combustion and homogeneous combustion are being tested to determine which method most effective.
Ordinary consumers can enhance the fuel economy of their vehicles as part of nature. Become increasingly popular fuel-efficient products in the market, but most of them did not really improve work efficiency. Such as tires maintained at a high pressure and a gradual acceleration and deceleration simple things, can be expanded vehicle, a fair degree of classification.
Hybrid electric vehicle is currently the best choice for those who want the speed and great fuel economy. These combine electricity and gasoline engine models to create some, like electric cars at all feeling. Hybrid vehicles recover energy, in the last hour to waste, resulting in inactive during the gas switch, and use of natural gas and electricity, while reducing the total fuel consumption. All of these factors combine in more than 50mpg and lower fuel emissions ratings.
