Zero-emission fuel cell vehicles
Although the Olympic Games and Paralympic Games have ended some time, but the success of the Olympic Games give us a deep impression, the event can be said to give the country the power to organize, in every respect to do our best, in the reception of the vehicles too. During the Olympics, there is such a team: they are from the 20 Passat Passat formed body of the vehicle the words "fuel cell car" from the shuttle at various venues and stadiums, the successful completion of tasks, covering a distance of thousands of km, but did not add a drop of gasoline, which is today's hero - Passat Passat fuel cell cars.
"Green Olympics, Scientific Olympics" is the slogan of the Beijing Olympic Games, Beijing 2008 Olympic Games as a vehicle partner, Volkswagen vehicles not only sponsor for the Beijing 2008 Olympic Games and Paralympic Games provides excellent transport security services, but also to a series of new energy vehicles provide energy-saving environmental protection, green travel services. These services are the Olympic Games in green new energy models from Shanghai Volkswagen Passat 20 Passat composition of the domestic fuel cell car has the largest fleet of fuel cell demonstration runs of the longest running record in a row, the longest total mileage record. Volkswagen in the spirit of "Green Olympics, Scientific Olympics", but also demonstrated its power in the new energy and new technology achievements. Is the hydrogen absorption of water row
Reduction are put in today in front of the world's major car manufacturers a major issue. While the manufacturers to explore new ways and means of energy is different, but their vision is the same - using renewable energy, clean energy as the future direction of development. So, who can take the lead in the new master of renewable energy power technologies, anyone can become the master of the automotive market.
At Volkswagen's powertrain technology and fuel development strategy, we see medium-term development of fuel still in liquid form, but not limited to oil, such as sun oil, synthetic oil, etc., are man-made synthetic fuels, to adapt to the current engine systems; but in the future will still be electricity, hydrogen as the main direction of development, can be said that hydrogen is currently recognized by the automotive industry to achieve zero pollution, clean energy. Hydrogen is currently recognized by the automotive industry to achieve zero pollution, clean energy. Volkswagen as the world's most powerful vehicle technology vendors, research and application of hydrogen has made certain achievements.
Fuel cell vehicle fuel cell power system consists of engine, fuel tank (hydrogen bottle), electric motors, power batteries and other components, the use of fuel cell power generation as the main energy source, through the motor drive the vehicle forward. Fuel cell power generation and routine chemical energy in different, more similar to gasoline and diesel engines. Its fuel (mainly hydrogen) and oxidizer (oxygen or air) is not stored in the battery, but outside the tanks stored in the battery. When the battery power, the need to continuously fed to the battery inside the hydrogen fuel and oxidizer, emissions of only pure water. Therefore, the fuel cell is a suitable vehicle, environmentally friendly hydrogen power generation devices. Its biggest feature is the reaction does not involve combustion, so the energy conversion efficiency from "Carnot cycle" restriction, the energy conversion efficiency up to 80%, the actual efficiency is 2-3 times of ordinary internal combustion engines.
"Green" service marathon
August 2007, the Shanghai Office for approval of new energy vehicles to promote the establishment of a "fuel cell car tech Olympics" special, planned trial 20 Passat Passat-based platform that integrates a new generation of fuel cell power system technology platform, the fuel cell car, provide transportation services for the Beijing Olympics. By the SAIC, Shanghai Volkswagen and the burning power more than ten units composed of joint R & D team, depth Passat Passat for fuel cell vehicle safety, reliability and comfort in terms of optimization, and the establishment of power system control, electrical safety, hydrogen safety, nine special technology development research group. Since July 5, 2008 began, 20 Passat Passat fuel cell car after another arrived in Beijing after commissioning, transport services into the work of the Beijing Olympic Games.
During the Olympic Games and Paralympic Games, this 20 Passat Passat fuel cell cars in 8 major Olympic venues to run around the provision of traffic management services; and, as a referee special vehicle for the Olympic Games and Paralympic Games marathon competitions security services. To ensure that the fuel cell car running smoothly during the Olympic Games, Shanghai Volkswagen, the burning power of about 100 people came together to form a model operation team to provide comprehensive technical support and operational security.
Fuel cell vehicles and ordinary vehicles, the difference between
Center console features increased, the data can be run real-time detection
We have seen in the center console of a style more common DVD car navigation, but the built-in functions which are far more than that, pressing the corresponding button, we can see the current vehicles in the state of charge and discharge, are to Comparison of the animation image of the way has been reflected; If you need more detailed test data, just press the toggle button to be able to check the drive motor, battery and fuel cell operating conditions, from the voltage, temperature, performance, and other data to understand the operational status of the vehicle.
If you encounter a problem, error code board computer will be displayed on the screen in a timely manner to facilitate the testing service staff. Dashboard display power, no speed
In the mass range of vehicles dashboard, usually on the left of the big table is a tachometer, and fuel cell vehicles in the replacement of vehicles has become one shows the current power of the instruments, instrument pointers in the idle state the basic point to zero-scale When the pointer speed when driving positive, he said that the issue of the actual drive motor power; and when the brakes when the pointer will drop to the negative energy that are now recovered.
Slightly less power, noise suppression is still needed
PASSAT fuel cells in Canada, after a full fuel can travel 235 km or more, to accelerate from 0-100 km time of 15 seconds, top speed 140 km / hour, for a gasoline version of the Passat This is simply for pediatrics, but for hydrogen fuel cell vehicles as an energy source for such data has basically met the needs of everyday driving. In the course of driving, the vehicle will be issued a similar sound like the plane took off, mainly from the intake side of the noise, because the fuel cell fuel cell outside, the more the faster the air will need to react, how to This part of the noise suppression is also the need to solve a problem.
Supply in different ways, a hydrogen supply the energy needs of 3-4 minutes where the vehicle is specially designed hydrogen refueling station, hydrogen refueling station at the time of entering here, we found that the requirements more stringent than the gas station, the door installed devices to eliminate static electricity , mobile phones for security reasons I have also been temporarily closed up, taking pictures is strictly controlled in the hydrogenation outside the region.
Vehicles hydrogen stations, by professional operators in the exhaust pipe of the ground with anti-static, and then connected through a special pipeline to the vehicle tank, the fuel fill process takes 3-4 minutes, a hydrogen fuel buses will have to spend 15 minutes or so.
In addition to the different characteristics of the vehicle itself, vehicle parking garage is also rather special, in the garage are installed on the roof of hydrogen sensors to detect vehicle fuel leaks and ensure the safety of the surrounding environment.
