Introducing fuel saving devices

gas saving tips

Due to economic crisis all over the world, people look for ways to save. Saving may have been disregarded before but at present, whether a person likes it or not, he/she must learn how to save. Commodities are having high prices. Rich or poor, people are greatly affected. Those who have vehicles really are faced with a dilemma on how to save fuel. They ask what are fuel saving devices? This question needs to be addressed because fuel prices from time to time is increasing.


People have looked for ways to increase fuel economy. Many technologies which claim to improve fuel economy are out in the market. Before you buy fuel saving devices, you need to know what these are and how these work. Most fuel saving devices claim an increase in combustion efficiency. Surprisingly, based on studies, fuel saving devices do not work as claimed. As what is stated in Wikipedia "On modern engines there is relatively little scope for improving combustion efficiency. Most of what can be legitimately achieved is done by reducing parasitic losses of accessories e.g. fans, water pump, and pumping losses by taller vehicle gearing."


If you are not convinced yet, you may have your own research regarding fuel saving devices. After all, the choice is yours to make. Fuel saving devices especially those advertised in the internet tell half-truths. Certainly, you would like to have the right value for your hard-earned cash. Understandably, people will fall into the trap of buying fuel saving devices for the endorsers of these products claim to have about 10-15% fuel saving, reduce emissions, improve performance, and cost about £50 (80 US$) (so costs about £5 to make!).


As a wise buyer, you want the right value for your money, right? Why don't you look deeper into these claims? Fuel saving devices claim to have 10 to 15% fuel saving. Is this claim supported scientifically? Scientific basis is always a necessity. Granting that there is a scientific test conducted, what cars were used? Do you think modern vehicles are used ? When test are conducted, very old cars are used. Olds cars are different with modern ones.


The next claim of fuel saving devices is on emissions reduction. Tony's Guide to Fuel Saving Gadgets revealed that "Measurements showing emissions reduction are nearly always taken from the UK MoT test or something equivalent. This consists of measures of hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO2), and is taken at idle. This completely ignores oxides of nitrogen (NOx), one of the most dangerous pollutants from car engines. It also ignores the fact that the emissions while driving are very different to the emissions at idle, because of the higher load and speed."

If your wish is to buy one of the fuel saving devices to help you save fuel, think again. You might just have added your expenses instead of saving.
