Brazil and Japan use of alcohol fuel

Automotive pollution control: the use of alcohol fuels Brazil and Japan, the United States and the European Union to promote new products, the introduction of new technology. Abandoned cars in many places it is difficult to deal with, and they cause serious environmental pollution problems dell inspiron 1150 battery, dell inspiron 5100 battery, dell inspiron 5150 battery, dell inspiron 5160 battery.

Gas emissions from cars are an important flow of pollution sources, vehicle exhaust gas pollution in large cities, one of the main gas. To address the issue of mobile pollution sources, to be used in a wide range of technical measures:

(1) the use of emission control technology. For example, improvements in vehicle engines, the use of thin mixed gas, the exhaust re-combustion of exhaust gas catalyst reaction such as the use of three, can reduce emissions of nitrogen oxides.

(2) to improve vehicle fuel. Taiwan from January 1990, all newly manufactured cars, are the use of lead-free cars, new cars to install catalytic converters, to 1995, lead and other gases decreased pollution. South Korea began in 1993 the application of carcinogens and other pollutants by half the number of low-pollution gasoline to reduce air pollution.

(3) the application of a new type of fuel. Alcohol such as gasoline, methanol, hydrogen and other fuels for vehicles. Full combustion of these fuels can greatly reduce the intensity of environmental pollution.

The first application of the Brazilian sugar cane bagasse fermentation enzyme engineering preparation of fuel alcohol, according to the proportion of alcohol and gasoline as a fuel compatibility. 90 years, most of the cars in Brazil used this mixed fuel. Germany, this alcohol fuel gasoline vehicles, a variety of climatic conditions in the safe driving. Japan also is developing ethanol engine, with a view to the full use of alcohol to replace gasoline as fuel. In 1990 compaq evo n600 battery, compaq evo n600c battery, compaq evo n610c battery, compaq evo n610v battery, compaq evo n620c battery, Japan's major cities are beginning to see the car as fuel drunk.

Car engine started, in the first few minutes of untreated discharges of pollutants, because inhibition of pollutants has not yet been heated catalytic converters to work state. Must be controlled to improve the air pollutants emitted from the first. To address this problem, the United States and precision combustion格雷格雷斯companies carried out a number of catalytic converters to installation of electric pre-heater, so that emissions of the first rapid increase in gas temperature. Using electricity to heat the gas with the metal gate is made of extruded metal powder. Followed by the emission of gases out through a ceramic substrate turn them into non-toxic gas. This latest product from Corning Inc., the prototype device is installed near the engine exhaust system. In a recent lab test, the device easy to reach California in 1997 for products developed by the strict rules. Corning's catalytic converter from a non-alkanes and carbon monoxide gas in California is less than half the limit in 1997. The device plus a metal gate that is, matrix layer, so that gas from entering the converter when the engine temperature.The energy of the substrate from a battery pack, it is not such a problem exists, namely: to enable the rapid temperature rise purifiers need a separate battery pack, or else the car needs a larger battery pack, which would increased vehicle weight and increase in vehicle costs.

Access to the European atmosphere of nitric oxide, 42% were caused by motor vehicles. Car is also dirty hydrocarbon emissions and carbon monoxide. In 1992, the European Community within the framework of all new cars equipped with catalytic converters, such as the type of new technology products in order to reduce the emissions of these pollutants. On the other hand, Volkswagen developed a new turbocharged diesel engine, fuel consumption than the traditional spark ignition engine to save 30% less carbon monoxide emissions by 20%. The use of such diesel engines than gasoline engines to clean money.

Volkswagen and the first to study the Bavarian Motor Company's car and then use a revolutionary technology, the hope that dumps the thing of the past field history. A pilot plant in Lille, in the trial on a number of Volkswagen Parts of plastics and glass, paint and other re-use. Volkswagen built a cost of one billion marks in 1993 to start a new public paint, completely doing away with chemical solvents, to water-based paint, which will significantly reduce pollution. Bavarian companies, the use of "removable design" new technology aimed at simplifying the parts and materials, so easy to disassemble and reuse car. Bavarian Car two-seater body d5318 battery, u4873 battery, dell inspiron 6000 battery, dell inspiron 9300 battery ZI all plastic manufacturers, as long as 20 to 30 minutes removed from the metal frame.

Excessive pollution has been measured a number of countries included in the scope of traffic management, Environmental Protection Agency that it is no longer a thing, but as a common action of society as a whole.

On the development of a new generation of solar cells

Recently, the Tokyo University of Science has successfully developed a "dye-sensitized type" next-generation solar cells, this battery-electricity conversion efficiency will be raised to 11%.
"-Type dye-sensitized" solar cells are used in materials and titanium dioxide pigment. In order to improve the photoelectric conversion efficiency, the researchers will be to control the size of titanium dioxide nano-scale, so that pigment can absorb light more dell inspiron 9400 battery, dell inspiron xps m170 battery, dell inspiron xps m1710 battery effectively.
