Cylinders for motor transport
|Multipla Bipower||Multipla Blupower|
The unusual minivan Multipla Fiat has made its debut in autumn 1998.
The car is available with different power supply systems. The 1.6v Biopower engine is designed to run on both petrol and methane (CNG, Compressed Natural Gas) while the 1.6 16v Blupower engine runs solely on methane. Two low environmental impact engines, the 'Blupower' (methane only) and 'Bipower' (with dual methane and petrol fuel system) - are proving to be a big hit with the public. The performances obtained using methane are on a par with those delivered by a petrol fuel system.
Methane is a clean fuel and thus meets Fiat's now customary low environmental impact requirements.
The fuel also burns without leaving any of the carbon wastes that sometimes arise when a car runs on petrol. The choice of methane does not affect the Fiat Mulitpla's load space: the tank (4 cylinders) is positioned under the floor outside the passenger compartment. This solution allows benefiting from a much higher fuel capacity than offered by other cars on the market.

There is no limit for pressure…
German certification agency TUV has licensed the first motor tank
specially designed for high pressure hydrogen storage. This tank stores
hydrogen at 700 bars.
Car Company "OPEL" decided to apply this novelty in its fuel cell concept
"HydroGen -3". So far, Opel designers have not dared to compress "the gas
of the future" at more than 300 bars pressure. However, the yearning for longer fuel distance forced them to design an extra high tensile vessel.
Gasification in Russia
New! Here you can see a schematic sketch of our hydrogen cylinders lay-out in Lada Antel-2 , the so-called environmentally clean car. Among its advantages are non- detrimental emission system and relative silence in operation. Hydrogen is kept in the light weight durable POISK-cylinders; their working pressure is 400 bars. The capacity of one hydrogen supply in cylinders guarantees up to 350 km non-stop run.
Gasification of Toyota's cars
In 1997, Toyota introduced the Prius, the world's first mass-produced hybrid vehicle. Wellcomed around the globe as an environment-friendly car, the Prius was one of the most fuel efficient 5- person mass-produced gasoline passenger vehicles in the world. The Prius became a core technology for the eco-cars of tomorrow.
Toyota FCHV (Fuel cell hybrid vehicle) introduced on a limited basis in the U.S. and Japan is seen as the closest yet to the ultimate eco-car. The hybrid system proven in Toyota's Prius achieves its highly efficient operation through sophisticated energy management of a gasoline engine and battery.
Toyota applied this hybrid technology to realize high efficiency in the Toyota FCHV as well. The TOYOTA FCHV's current cruising range is about 300km (in the Japanese 10-15 test cycle), which is still far from satisfactory.
To match the cruising distance of a gasoline engine vehicle, much more hydrogen needs to be carried on board.
Instead of a high pressure hydrogen tank, it is possible to use a hydrogen-absorbing alloy tank. However, neither method is yet sufficient. Attaining the required high storage efficiency is a difficult challenge, which Toyota is facing with further development efforts, including increasing maximum tank pressure. So far each tank stores hydrogen at 35 MPa (about 350 bars).
