Revolutionary invention of a team of engineers Var: a compressed air engine and very economical not relieve any gas. He appealed to authorities in Mexico, one of the most polluted cities in the world. The engine is clean, not only in the imagination of some utopian environmentalists. This is not an electric motor, it runs on compressed air. A group of eighteen engineers and technicians working for over five years in Brignoles (Var), this innovative process which has had the idea in 1991 with an engine, Guy Negro, which had appealed for thirty years as well prestigious Formula 1 teams as the aviation industry. Each system's fuel From his experience in F1, Guy Negro drew a conclusion: the cars racing start - but start only - through a compressed air turbine. Why not use compressed air as fuel when the vehicle needs only little energy, in town for example, which arise just the pollution problems? For floor with confidence on the concept of cleaner cars, the engine has completely abandoned its business among manufacturers and established his company, QED Air Solution, headed by a parent company, Motor Development International, based in Luxembourg. His first contract, MDI has just signed with the Mexican government and industry came especially from Mexico, the largest city in the world unbearable. They will create their homes, licensed child revolutionary French company. At the beginning of the adventure, the team of Guy Negro interested in a dual energy engine: gasoline, diesel or LPG (liquefied petroleum gas) to travel outside urban areas and air in urban areas. Christian name: MDI EV3. In heat mode, for the road, it was also designed to reject the least oil. "Usually, all the thermodynamic cycle is in the same cylinder. Here, we separated the functions - intake, compression, combustion, expansion, exhaust - in separate chambers to optimize the engine cycle, said Guy Negro. With the burning time of three to four times longer than what is classically, in a compact room ideal form, the exhaust emissions are much lower than that recorded on the current catalyzed engines. " Air cleaner after use before This notable performance was overshadowed by the technical achievement that represents another aspect of this invention (patented worldwide, it goes without saying): functioning urban air. At low rpm, enough for around town, MDI EV3 is not powered by gasoline, compressed air is breathable, which takes over, stored in over 200 bars of pressure in a reservoir of carbon, the type dive tank. The principle is simple and based on elementary physics. This system is of interest that should delight the environmentalists. Under the hood of the vehicle "zero pollution" is a mini-high-pressure compressor, driven by the engine, which will suck in outside air during deceleration and braking. The impure air through charcoal filters and a kind of molecular lock. After playing the role of fuel, it will be rejected in much cleaner air. "We have made proposals to the City of Paris to re-engine the 4 000 buses and garbage trucks. This would represent 15 million cubic meters of air cleaned per day in a city where pollution is a concern, "says the chief engineer. The RATP has, apparently he was not unsympathetic to the argument, but he needed something concrete: a heavy motor vehicle duly tested. "Our company did not have the infrastructure necessary to achieve this, especially not suitable testing bench. "The QED team has decided to reduce the volume and build a single-engine power - Compressed air only - hosted by a taxi new look, also concocted by the company Brignoles, with the help of a designer Italian Bugatti. His name: T0P (taxi zero pollution). Thus was born a car of the century, which meets the criteria of interior space, comfort, silence (due to low pressure at the opening of the exhaust) and of course completely safe for the world outside. In addition, unlike the catalyst, the cold does not escape the dreaded greenhouse effect. It's a Citroen AX which served as guinea pigs for testing of MDI "zero pollution". Huge files studying its "fathers" Brignolais last arrived on a perfect success. Card engine: 60 to 80 HP at 7 000 rpm, 34 kg, 15 liters of high pressure compressed air for an hour commute in town. Maximum speed: 100 km / h, capacity of reservoirs in the taxi: 300 liters. And a full 10 F-peak. The filling of reservoirs (one main and a "charge") can be done in two ways. Either the driver went to a station of high air pressure - garages and service stations will be equipped. This is done so in three minutes. Either the driver plugs into his garage, on an ordinary electrical outlet, the compressor built for four to five hours. This cleaner cars whose maintenance is virtually nonexistent, does not handicap his colleague electric batteries too heavy and too expensive ... 87 000 taxis Mexicans gradually replaced She then seduces José Luis Tamargo, chairman of the parliamentary committee on transport and roads of Mexico, Margain Leonardo Lazo, Director General of that committee, and Francisco Perez del Rincon, a manufacturer of the car in Mexico, especially from the Last summer in Brignoles. "Having learned of our work by French agents installed in Mexico, they told us they had reviewed dozens of proposals around the world, but they had never studied a system as realistic and economic ours. And that could prove decisive for the future of their country, "says the son of Guy Negro, also an engineer who learned his Bugatti. After multiple tests, the licensing agreement has been signed in late 1997, the remaining patents owned by MDI. Specifically, this should result in the gradual replacement of 87 000 taxis spew their gas pollutants in the air of Mexico City. And the Government suggests that a law could be passed to require taxis and public service vehicles to convert to compressed air! Gasoline is taxed fairly low in Mexico, its replacement by a "fuel" very few would not create costly for the state a big shortfall. The minivan, or yellow, or green, whose prototype is already developed, and clean engine will be built in the suburbs of Mexico City in the next two years. Manufacturing costs should be lower than a conventional vehicle, "particularly because of the low engine weight, according to experts ... And the finished product could return to Europe, where it continues to seek solutions to the scourge of pollution, without picking a solution at hand. In shops now Var, technicians studying other versions of the taxicab yellow vans and pickups, deliveries or for municipal services. They nonetheless continue to improve their flagship vehicle. "We also wanted the comfort of the driver and passengers, said one of the" planners "of the minivan, three or four seats vis-à-vis the rear and ample space for legs, a flat floor, single sliding door wide side of the sidewalk. And his size - 3,84 m long and 1.72 m wide - is not a parking problem. "In fact, the body resembles that of English taxis. The "little more" no shortage of attractions: integrated air, television, telephone, minibar, satellite guidance display with various information on the dashboard ... Thinking as the disabled, the engineers have provided a ramp for wheelchairs. The luggage compartment is located next to the driver, who was alone in front and a window can be isolated from the rest of the cabin. Twenty patents engine, taxi and finds their schedules have already been filed. "We may reach their thirties," says Guy Negro, who has been contacted by industrialized Asian, British and Dutch, very interested. The French manufacturers, to whom he submitted his project, responded with a vague "we'll talk about it or did not respond at all ...
