There is an alarming concern all around the world. It is the increasing unavailability of fuel. In the 21st century fuel is considered more valuable than gold or diamond. The countries with better stock of oil and natural gas tend to have a better economy than others. So considering all these factors it can be said that saving fuel is the only way for us to ensure proper utilization of valuable resources. The principal users of these natural resources are vehicles. Vehicles all over the world together burn gallons of petrol, diesel and gasoline each day. So if somehow the fuel efficiency of the vehicles can be increased we can save our useful resources for longer times. There are many technologies aiming to achieve the Goal. Some of the latest technologies in this area are as follows.
Improved diesel quality:
One of the ways that can be used to help the fuel consumption is to increase the quality of fuel. Fuels such as diesel are generally not used in the countries like America. This is due to their low quality and high pollution rates. Diesel being more cost effective and available than petrol can not only help the environment but also prove economic. The new generation diesels offer more value and quality. The emission of toxic Nitrogen based gases and other harmful dust particles can be regulated now thanks to the new diesels in the market.
Injecting fuel directly:
Injecting the fuel directly can greatly help both in the fuel efficiency and the performance of the vehicle. The standard way of injecting fuel to the engine is by first mixing the fuel with air and then sending it to the combustor .In place of that this technology directly sends the fuel to the combustor. It has a positive effect on power and cooling also. Some used cars use this mechanism.
Turbo charging:
Turbo chargers has become a must have for all the modern power pack 
engines. Turbo chargers give the engine the much needed power boost. The chargers accelerate the fuel and send it to the engine. This increases rate of combustion of fuel and helps the car to achieve power that cannot be achieved by regular engine of the same specifications. The main advantage of turbo charger is that it can help small engines provide great power when required. Used car Business companies sell cars having turbo chargers.
Improved valve mechanism:
The Valves open and close to let fuel and air get into the engine. They let the gases form the engine to go out. In recent time it is possible to control the timing of the valves. This gives the vehicle power when needed along with better control in fuel management. Some used cars have this feature in their engines.
Conclusion:
It is certain that these technologies will surely change the current cars into a more fuel efficient and productive vehicles in the future. Some used cars which has engines using these kinds of technologies can be an even a better choice. This is due to the fact that you get a car with a latest engine in much less price.
