Contend with fuel cell vehicle

Speaking of a new generation of cars, the most powerful when the number of candidates in order to hydrogen-powered fuel cell vehicle laptop battery. However, there are many issues compared to the fuel cell vehicle,Hp laptop battery there are a number of new technologies and as a result of more realistic and compelling. This is the electric motor with the engine and the hybrid, as well as in Europe, promoting the popularization of the main diesel engine vehicles.


In these new technologies and intense competition for dominance in the competition when it unexpectedly From a surprise. This is the Mazda is developing a "hydrogen rotary engine" car.


To ¥ 5,000,000 each (about 384,000 yuan) for the target


Fuel cell vehicle is hydrogen and oxygen through a chemical reaction to obtain power, and Mazda's hydrogen engine is based on hydrogen-fueled internal combustion engine. The world dedicated to research and development of hydrogen engines only Mazda and BMW in Germany. Mazda since 1991, HP PM579A Battery, HP Pavilion DV4000 Battery(hp dv4000 battery) , HP Pavilion ZE2000 Battery(hp ze2000 battery), HP Presario M2000 Battery(compaq m2000 battery), has been engaged in the development of hydrogen engines. Up and down movement of the piston engine general it is difficult to control the combustion of hydrogen toshiba battery. However, HP PM579A Battery,Mazda's proud ---- let alone technology triangle rotating rotor rotary engine is very suitable for control of hydrogen combustion, hydrogen engine is Mazda eyes on this point.


"The goal is 3 to 4 years in the practical operation." In October last year, Mazda's president Hisakazu Imaki in Tokyo Motor Show this Declaration issued Zhuang, before the specific surface of the strategic plan. The next 2 years with a hydrogen engine will be the first to government agencies and enterprises to carry out video, then consider selling in the market. February next year will add an additional hydrogen Mazda headquarters facilities for the practical use to prepare. In addition, the need to spend huge sums of money from the fuel cell vehicle Mazda's largest shareholder - the United States responsible for the development of Ford, it can be wholeheartedly Mazda hydrogen rotary engine development. Rotor hydrogen car is the most important weapon to reduce costs. At present, such as Toyota and Honda are rented or sold to government agencies, such as fuel cell vehicle, but the body is said to vehicle prices in the ¥ 100,000,000 (about 7.69 million yuan) or more. Fuel cell vehicles as a key part, so that hydrogen and oxygen react chemically generate electricity, "battery pack" in terms of cost to occupy a large proportion of future development work still needs to invest heavily.


At the same time, hydrogen basic structure of the rotor of motor vehicles in April last year began selling sports car of the "RX-8" compared to almost no change. Just add an additional hydrogen to the combustion chamber of the injection device, placed in the trunk of the hydrogen storage tank and the hydrogen leak detection sensor can be.HP Pavilion DV4000 Battery(hp dv4000 battery) , Even the engine room, compared with an ordinary car is no different, you can use the original intact production equipment to reduce new investment.


RX-8 in the prices of ¥ 2,000,000 (about 150,000 yuan) from top to bottom, and "practical rotor of the hydrogen car will be the market price of about ¥ 5,000,000 in the objective to develop" (project development to promote this Investigator Zhanghong Kashiwagi). It is certain that the low supply prices will be fuel cell vehicles can not match.


Hybrid is also under consideration


Kashiwagi full of looking forward to the future: "Hydrogen is not a simple rotor 'convergence' petrol truck and a car battery technology. Hydrogen supply facilities in the future even if fuel cell cars have become the mainstream of the times, but also need to use, so the rotor hydrogen fuel car can be cell vehicles continue to coexist. "


However, the true hydrogen car to universal rotor that there are still some technical issue toshiba satellite m40 battery, toshiba satellite m45 battery. Rotor current development of hydrogen cars, hydrogen can only be added once traveling 70km. Although it could be combined with gasoline, in the practical aspects of the problem does not exist, but such a short distance or to undermine the significance of the next generation of engines. In addition, the use of gasoline can produce 210 horsepower at the power, and then switch to hydrogen is only about 110 horsepower, HP PM579A Battery, HP Pavilion DV4000 Battery(hp dv4000 battery) , HP Pavilion ZE2000 Battery(hp ze2000 battery), HP Presario M2000 Battery(compaq m2000 battery), a reduction of about half the horsepower. Even if these problems can be solved, but "still need to study hydrogen storage battery and the motor rotor and the combined hybrid system." (Okada and Mazda's executive director)


Rotor engine in the 90's have had to stop the development of endangered plight. HP Pavilion ZE2000 Battery(hp ze2000 battery),It difficult to cope with increasingly stringent environmental standards are the main reason. However, this is the rotor Mazda engine may become a new generation of environmental technology trump response.


U.S. R & D of micro-generators to replace the phone battery


Recently, the USA and Georgia Institute of Technology announced that with the Massachusetts Institute of Technology, working closely with scientists, they have successfully developed a micro-generators, only 10 mm in diameter, is the continuing use of mobile phone battery is more than 10 times. Scientists will be held in January next year, the International Conference on Micro Electro Mechanical System published the results of this gratifying.


Georgia Institute of Technology is one of 10 open construction, computer, engineering, management and other professional, a total of 16,000 students in the United States is to train African-American women scientists and the best scientists, a university, research university is 2003-2004 academic year a total of 342 million U.S. dollars of research funding.


Over the years, more and more compact electronic products, and its battery has a larger volume of plays. In order to solve this problem, the scientists have been dedicated to the development of micro-generators, and put forward a number of different principles of micro-generators. And the Georgia Institute of Technology scientists have developed such a generator to replace the phone toshiba satellite m50 battery, HP PM579A Battery, HP Pavilion DV4000 Battery(hp dv4000 battery) , HP Pavilion ZE2000 Battery(hp ze2000 battery), HP Presario M2000 Battery(compaq m2000 battery),toshiba satellite m55 battery, indicating that micro-generators to enter the electronic products to replace conventional batteries and an important step.


The principle of the micro-generator is installed in a chip on the induction coil, so that a small rotating magnet around the coil, resulting in sufficient current. Through continuous testing, the rotating speed of the magnet is now up to 100,000 per minute lap,HP Presario M2000 Battery(compaq m2000 battery), the speed can generate 1.1 kilowatts of electricity, enough to replace the phone battery. The researchers said that will be sure to have a speed of 20-50 kilowatts of power for laptop computers. In order to improve the rotation speed, the most critical problem is how to avoid rotating magnet in the process of fracture. Centrifugal force generated by high-speed rotating magnets broken enough to make, in order to solve this problem, researchers continue to improve the size of magnet and wrapped in titanium alloys in.
