Oil will be burned The downward Ruqierzhi. The National Development and Reform Commission recently announced that, since the 9th of gasoline and diesel prices 530 yuan and 510 yuan per ton, respectively, to reduce. Beijing?s refined oil prices return to the era of However, industry experts believe that even if the current level of crude oil prices on the economies is still a heavy burden. The second half of the year, the U.S. economic trend is getting better and better, the introduction of stable growth policies to reverse the economic downturn, will boost oil demand, not exclude higher international crude oil prices again. In this context, how to implement the spirit of the Energy-saving and new energy automotive industry development plan pointed to pure electric drive as the main strategic orientation of the transformation of the automotive industry, this focus on promoting pure electric vehicles and plug-in hybrid electric car industry and popularizing non-plug-in hybrid vehicles , energy-efficient internal combustion engine vehicles to enhance the overall technological level of China?s automobile industry. The reporter should focus on technological innovation and industrial incubators for new energy sources and hybrid vehicles, focusing on tapping the potential of energy recovery. unidirectional energy flow of the the
the traditional internal combustion engine vehicles, electric vehicles, plug-in hybrid cars and hybrid cars thanks to the energy management system, can make use of the kinetic energy is converted into electrical energy to achieve the recovery of braking energy , more and more energy-efficient models hub motor, improve energy efficiency. But look to the future, be able to recycle not only braking energy include heat, shock absorber kinetic energy.
reporter recently interviewed the inventor ShockEner high-performance shock absorbers project Peking University Master Liu Cheng of the Department of Electronics, Beijing University of Aeronautics and Astronautics Mechanical Engineering and Automation in reading Dr. Jin Yang. Liu Cheng, the role of the traditional automobile shock absorber vibration energy into heat energy dissipated in order to maintain the safety and comfort of the car body. ShockEner technology damper mechanical consumed energy is converted to electricity, and 3-10% of the energy recovery. in
interview, Liu Cheng specially briefed reporters on the end of 2009, a completely consistent GenShock with ShockEner principles and design technology in the birth of the Massachusetts Institute of Technology, get a lot of awards, quickly get millions of dollars the investment, its products have been used in Humvee (test fuel-saving rate of 6%). In contrast, ShockEner technology earlier than GenShock technology two years, was born, made five core patents in the field since 2007, including two invention patents, with completely independent intellectual property rights. While energy recovery, ShockEner technology can also be used to achieve the independent intellectual property rights have full national semi-active and active damper.
but so Liu Cheng annoys them, the application of energy-saving shock absorber technology industry and incubator facing financing difficulties and bottlenecks. Whether the wave of industrialization of new energy vehicles and hybrid cars can accelerate the promotion and application of this energy-saving technology, Liu Cheng was filled with hope.
BMW Efficient Dynamics is committed to continue in-depth study of immense potential in the exhaust heat shock absorber converts kinetic energy into electrical energy energy saving ideas. BMW staff, according to reporters, even the most efficient internal combustion engine can only be about one-third of the energy generated by fossil fuels into mechanical kinetic energy required for the motor vehicle. In the past few years, the BMW Efficient Dynamics with direct fuel injection, variable valve timing, exhaust-driven turbochargers, brake energy recovery system and automatic start-stop function, significant improvements in engine efficiency. However, the energy generated by the fuel is still about 60% loss, half of them into the exhaust gas heat, the other half of the waste heat of the engine cooling system to absorb.
find effective heat recovery method to become one of the relentless pursuit of the goal of BMW EfficientDynamics engineers. To this end, the BMW Group plan through a series of projects in research and development, various attempts on the different aspects of the pre-production and production stages of the loss of heat utilization. Among them, the most promising innovation projects including turbine steam engine, thermoelectric generator, engine encapsulation technology and waste heat exchanger is used to fuel heating. turbine steam engine
thermoelectric generator project are the use of the waste heat power generation as the focus, in order to improve the overall efficiency of the engine, but the methods and at different times of each project. If you achieve through waste heat for all systems powered vehicles, rather than rely entirely on vehicle generators will have very far-reaching significance for the fuel-efficient.
kg, and provide all the necessary electrical energy when the vehicle is cruising on the highway or country road. As a result, in the long-distance travel, the most fuel consumption is expected to reduce by 10%.
In addition, the energy recovery system also brought some interesting additional benefits, such as cold start the engine or passenger compartment heating system to provide additional heat. Thermoelectric generator or efficient dynamic braking energy recovery system ideal complement. The braking system to decelerate and stop producing energy, thermoelectric generator (that is, the passion driving acceleration) with the best functionality. The researchers predict that in the actual day-to-day driving conditions in the future, this energy-saving system up fuel consumption can be reduced by 5%. device of the idle fuel
start parking, braking, recovering kinetic energy hub motor, the kinetic energy of the shock absorber and the combustion heat into electricity for the vehicle, new energy vehicles, energy management system creatively two-way flow of energy. The reporter who test drive BMW?s pure electric car, the Benz hydrogen fuel cell vehicles, the Toyota Prius hybrid car when driving on the screen to display the realize will burn oil
