The author had an opportunity to ask from the people who make a business survey the in Italy and found that the market of gas for vehicles was a quite interesting because many people do not know that in some countries, the engines of the cars they drive in everyday life have been modified in order to be able to burn other kinds of gas that cost more lower than diesel or benzene.
Italy is a country that uses gas as their fuel, which are Liquefied Petroleum Gas (LPG) and Compressed Natural Gas (CNG).
The number from LPG Euro cars users association and the number from the manufacturer that produces modification kits for cars for other kinds of fuel indicated that there are 1.3-1.4 million cars that use LPG (or GPL in Italian), while 0.3-0.4 million cars use CGN (or Metano in Italian). Italy is a country that uses these two kinds of fuel the most in Europe, as well as the production of modification kits for cars.
On April 28th, 2006, the price of LPG in Italy was Euro 0.63/liter (USD 0.75), while Benzene was Euro 1.50/liter (USD 1.76), which was 2.35 times difference. It is the normal system that the price of LPG is lower than 2.3-2.5 times of Benzene’s, while CNG’s is around Euro 0.50/Kilogram (USD 0.60). This means that CNG’s price depends on weight, not on volume.
Although LPG’s and CNG’s prices are much lower than diesel and benzene, the growth rate of them in Europe is slightly slow and starts to reach their peak point. We can see from many countries in Europe such as England, Italy, Germany, Belgium, Netherlands, and France, or some countries in Asia such as Japan and South Korea, small-sized cars with low-rate fuel burning engines are more likely to be the majority rather than large-sized cars with high-rate fuel burning engines. Modification of cars for CNG or LPG is more suitable for large-sized cars rather than small ones because it needs some space in the cars to install it, and the installation fees and price for the equipment are high around Euro 1500.00 so that the break-event point will be around 2-3 years or more.
The general property of gas is no color and smell, but what we can smell from it is from the chemical mixed in so that we could notice the gas leak. Gas for cars is the fully burning fuel, and this helps reduce the green house effect which causes the global warming. However, there is also a disadvantage from it. It is a fuel that can harm engines in the long-term because it is gas itself. There is no lubricity property, and it also creates high temperature in burning process.
Even though the gas for cars has nothing to do with our everyday lives, in many countries, it is widely used because of the different price of fuel in each country. If the price is too high, the alternative choice is always considered in users’ calculation, especially with the public cars which run for very long distance each day. The cheaper one means the cheaper cost. Therefore, gas for cars would be a topic that must be talked about whenever the price of gas so high that many people cannot afford to use.
