Air Car Project

MDI CAT´s compressed air technology cars.

 

MDI introduces compressed air vehicles to the market.

 

 

MDI has developed a high performance compressed air technology. When it is compared to traditional gasoline powered engines, MDI´s engine is far superior in terms of energy used and thermodynamics.

 

An overview of the air car

The technology that MDI vehicles use is not new, in fact it had been around for years. Compressed air technology allows for engines that are both non polluting and economical. After ten years of research and development, MDI is prepared to introduce its clean vehicles onto the market. Unlike electric or hydrogen powered vehicles, MDI vehicles are not expensive and do not have a limited driving range. MDI cars are affordable and have a performance rate that stands up to current standards. To sum it up, they are non-expensive cars that do not pollute and are easy to get around cities in.

Two technologies have been developed to meet different needs:

Single energy compressed air engines

Dual energy compressed air plus fuel engines

The single energy engines will be available in both Minicats and Citycats. These engines have been conceived for city use, where the maximum speed is 50 km/h and where MDI believes polluting will soon be prohibited. It is already possible see examples of this in some places, such as London, where you want to enter the city center with gasoline powered vehicles, you must pay a fee.

The duel energy engine, on the other hand, has been conceived as much for the city as the open road and will be available in all MDI vehicles. The engines will work exclusively with compressed air while it is running under 50 km/h in urban areas. But when the car is used outside urban areas at speeds over 50 km/h, the engines will switch to fuel mode. The engine will be able to use gasoline, gas oil, bio diesel, gas, liquidized gas, ecological fuel, alcohol, etc.

Both engines will be available with 2, 4 and 6 cylinders, When the air tanks are empty the driver will be able to switch to fuel mode, thanks to the car's on board computer.

 

Urban vehicles: Minicat's

 

 

Longer distance vehicles: Citycat's (the new CityCat's design will be introduced soon)

 

 

Taxis: a taxi version of the Citycat

 

Apart from applying its technology to CAT´s vehicles, MDI is also developing compressed air engines for other fields, such as electric cogeneration and energy accumulation. See other applications

MDI has recently been rewarded for its hard work and long investigation into clean engines. Last February, the French government awarded MDI the "La Palma de Oro de la Academia Nacional para el Fomento de la Creatividad Industrial, Artesana y Artística."

A car to dress an engine

During the first phase of development, Guy Nègre, thought that he could develop an engine and sell it to the large automotive manufactures. Unfortunately, because adapting an air engine to traditional cars meant changing bodies and production line the large companies refused and he was forced to change his approach. The inventor then set out to develop a vehicle according to his philosophy. This car had to be ecology friend, silence, and practical.

During the following years, MDI decided to further develop its vehicles. The result is a clean, easy to drive, high performance car. MDI has achieved what the large car manufactures have promised in a hundred years time.

The end product is a light weigh vehicle that can reach speeds up to 220 km/h (even though the legal limit is 120.) A product that does not pollute like twentieth century vehicles and does not take a lifetime to pay off. Essentially, MDI has developed a modern, clean, and cheap car that meets most peoples needs. That is to say that 60% of drivers drive less than 50km a day, and 80% of those 60%, never leave urban areas.

Unlike the majority of traditional cars on the market, MDI´s vehicle's have fibreglass bodies which makes them light, silent urban car. The car's body is tubular, light weight, and is held together using aerospace technology.

The vehicles do not have normal speed gauges. Instead, they will have a small computer screenthat shows the speed and engine revolutions. The system allows for infinite possibilities such as GSM telephone systems, GPS satellite tracking systems, programs for delivery people, emergency systems, internet connections, voice recognitions, map presentation, traffic information... in three words: the future is now.

Regarding security, the seatbelt system is different from what we know. One part of the belt is anchored to the floor of the car, like traditional cars. The other part of the belt, in stead of being attached to the side of the car, is also anchored to the floor of the vehicle. This helps to secure the bodies of the driver and passengers in the case of a collision. The vehicle's electric system is also revolutionary. MDI has bought a patent that is bound to reduce the important of electrical systems in all cars. The trick consists in using a small radio signal. The system makes the car 20 kilos lighter and considerably quieter.

MDI is also considering a system to replace traditional keys. This system would utilize an access card. With this card it would be possible to open the car from a short distance away without having to actually insert anything in the car.

In the single energy mode MDI cars consume less than one euro every 100Km. (around 0.75 Euros) that is to say, 10 time less than gasoline powered cars.


 

When there is no combustion, there is no pollution. The vehicle's driving range is close to twice that of the most advanced electric cars (from 200 to 300 km or 8 hours of circulation) This is exactly what the urban market needs where, as previously mentioned, 80% of the drivers move less than 60Km. a day.


 

The recharging of the car will be done at gas stations, once the market is developed. To fill the tanks it will take about to 2 to 3 minutes at a price of 1.5 euros. After refilling the car will be ready to driver 200 kilometres.

The car also has a small compressor that can be connected to an electrical network (220V or 380V) and will recharged the tanks completely in 3 or 4 minutes.


 

Because the engine does not burn any fuel the car's oil(a litre of vegetable) only needs to be changed every 50,000Km.


 

The temperature of the clean air expulsed form the exhaust pipe is between 0 and 15 degrees below zero and can be subsequently channelled and used for air conditioning in the interior of the car.
