Future Drive: Hydrogen-diesel from BMW

Engineers from the BMW developed a new cylinder head for hydrogen operation based on a production diesel engine. BMW designed high pressure injectors for direct injection of hydrogen into the combustion chamber with pressures of up to 300 bar, nearly 4500 psi. With the diesel base, however a much better efficiency, with the new technology reached 42 percent and this is on the level of conventional self-ignition. The series using the new technology are technical side, according to Development Director Falk Gerbig no insurmountable obstacles contrary.

The project H2BVplus, an H2-ignition combustion process as a possible cars propulsion of the future will be further investigated. With regard to performance and efficiency can be distinguished from conventional diesel interesting aspects derived. The H2-ignition concept is to increase the efficiency and specific performance is expected.

Still holds the BMW hydrogen combustion because of the relatively low technology and low cost space, particularly for a good alternative to hydrogen fuel cells

Range and cost information of fuel cells (FC EXPO 2009)

An important issue for fuel cell vehicle at the moment, “range”, “sub-zero start”, “FC improving the durability of the stack” and “cost reduction” in the fourth.The range is as was mentioned earlier, on par with gasoline vehicles already achieved more than 500km. Loss and loss of electrical energy and heat loss of the inverter stack 15 percent reduction by increasing the amount of regenerative energy of the vehicle, model year 2005 about 25 percent more fuel economy improvement. The addition of hydrogen filling pressure from 35MPa and 70MPa, about the amount of hydrogen can be used to expand the volume of the 1.9-fold improvement.

“Between 2008 – Tokyo, Osaka (560km), was able to finish filling in the actual use conditions and no air conditioning. After the fuel has been left to finish, and later were able to estimate the road about 250km I “(Mr. Masuda)

“Starting below zero” for the problem is almost solved. The fuel cells produce energy to produce water with Originally, the system starts to freeze it in below freezing water was a major challenge. The supercooled state of water – the frozen state before solidification of water – sustainable technology, and the matter settled. Today, Toyota and other manufacturers, minus minus 25 ℃ and 30 ℃ of the system can start. “We went to the testing of the Canadian Arctic. Minus 30 ℃ following morning, it was minus 25 ℃ day following a cold place, I could start without any problems no” (Mr. Masuda)

“FC Stack Durability improvement” in reducing the degradation by chemical and physical endurance has improved steadily. The current challenge is to curb further deterioration catalyst and electrode.

The challenge is the most popular, and “cost reduction”.

Of the possible measures, the larger two. First, in the field of design, and simplification of the FC system to smaller and lighter stack. Then, in the materials sector, in cooperation with materials manufacturers, FCHV promote low-cost construction material of the car. This ultimately cost Mr. Masuda’s tenth goal of the talks. Particular challenges, FC, and reduce the amount of platinum and other precious metals used in the stack, both increasing efficiency and compact, complete with cheap how to enable the high-pressure carbon fiber tanks to take a driving range.

And resolve issues, and Masuda 2015, aims to spread to the general public will begin to speak, concluded as follows.

2009 Geneva Motor Show: Citroen GT is about to mass production?

2009 Geneva Motor Show: Citroen GT

Modeling of extreme science fiction of the Citroen GT is actually from the virtual digital world came on the Geneva Motor Show. The concept cars are Citroen and Sony’s Polyphony Digital developed in cooperation, as a Sony home console platform PS3 games “Gran Turismo 5 (GT5)” inside a car. At swim, according to Citroen GT in name is “GtbyCitroen”, she was set to use a fuel cell, power-driven, non-emissions car. And this classic racing game “Gran Turismo” series has also been hot in the world has more than 50 million sets.

At Geneva Motor Show on the basis of the latest message, this length 4960mm, width 2080mm, a 1090mm high Citroen GT, is likely to move toward volume production of a formal and limited production will only be 20, some of whom may be carrying power from the Ford’s 5.4 liters supercharged engines, or engines from GM, let us wait and see.

New Mercedes-Benz Citaro FuelCELL Hybrid Buses

Mercedes-Benz Citaro FuelCELL Hybrid

Germany’s Daimler in 2009 was held on Monday in Vienna, Austria “World Congress and Mobility & City Transport Exhibition” (2009 years Sunday June 7-11), Mercedes-Benz’s fuel cell hybrid bus “Citaro FuelCELL Hybrid “to announce.

The company has a 1997 bus test vehicle equipped with a fuel cell system in the world’s first “NEBUS” it said. The Citaro FuelCELL Hybrid development is an extension of the fuel cell system with a “Fuel Cell Citaro” and “Citaro G BlueTec Hybrid” system, incorporating the elements of the hybrid-diesel technology. Citaro G BlueTec Hybrid is equipped with a motor axle hub, Li-ion secondary battery, and share the power supply system for electric components. In addition, driven by precise control of hybrid systems, that reduces fuel consumption compared to conventional fuel cell bus.

The company soon will begin testing as a normal bus operation in several cities in Europe. This experiment, the years 2003-2006 in EU fuel cell bus trials conducted by “CUTE (Clean Urban Transport for Europe)” will get along. Since 2003, a total of 36 Mercedes-Benz Citaro buses equipped with fuel cell drives have performed outstandingly at 12 public transport agencies on three continents as part of the CUTE test, its HyFLEET:CUTE followup project, and other related testing programs. The buses were driven a combined total of more than two million kilometers in a total of approximately 135,000 hours of operation. Their availability between 90 and 95 percent impressively demonstrated the environmentally friendly fuel-cell drive’s suitability for everyday use in urban regular-service buses

Magna is presenting Mila ev at at the Geneva Motor Show 2009

The outstanding element and centerpiece of the mila ev is its fully integratedelectric vehicle platform which can be used by every OEM to realize their ownproduct, drive and design strategies in the shortest of time.

Concept mila ev is a 5-doors vehicle with a length of 4 m and a wheelbase of 2.5 m. It loads an electric motor of 67 hp, powered by a lithium-ion battery developed by Magna Steyr. At an average charging time of 2.5 hours, ranges of up to 150 km can be achieved.The curved lines of the body to provide an elegant and futuristic aesthetic.

The novel platform on which the mila ev is based is a completely developed conceptwhich can be used for production-vehicle development immediately and thus forseries production in the shortest of time as a genuine electric vehicle or, thanks tothe intelligent design, with natural gas, fuel cells or hybrid drive.
