Abstract:

Considering that we live in a very mobile society, it's probably safe to assume that you have. While pumping gas, you've undoubtedly noticed how much the price of gas has soared in recent years. Gasoline, which has been the main source of fuel for the history of cars, is becoming more and more expensive and impractical (especially from an environmental standpoint). But cost is not the only problem with using gasoline as our primary fuel. It is also damaging to the environment, and since it is not a renewable resource, it will eventually run out. These factors are leading car manufacturers to develop cars fueled by alternative energies. One possible alternative is the air-powered car. There are at least two ongoing projects that are developing a new type of car that will run on compressed air. One among them is the e.Volution Cars.

After more than thirty years experience with combustion engines, the French engineer Guy Negre has developed a concept of a totally non-polluting engine for use in urban areas. This invention, which uses high pressure (300 bar) compressed air to store the energy needed for running the engine. When the air is injected into the cylinder chamber, it expands to provide motive power. Oddly, the problem with a conventional four-stroke engine is that compression, combustion and expansion all take place in a single cylinder. But here the engine divides these functions into a three-chamber system, with one cylinder for compression, a small chamber for combustion and a much larger cylinder for expansion.

Zero Pollution Motors is also working on a hybrid version of their engine that can run on traditional fuel in combination with air. Mono-energy engine have demonstrated the viability of the new concept, the air and fuel, bi-energy, engine will be introduced to major car manufacturers in order to study its adaptation for their common models.
