Engine power lift out "combination boxing": two level Turbocharging Technology
In recent years, small displacement engines have been highly praised by many automobile companies. Turbocharging technology has made outstanding contributions to the power upgrading and fuel economy optimization of small displacement engines, and has gradually become a technological trend. With the continuous improvement of environmental standards, emission regulations and engine technology, a variety of technology combinations to enhance engine performance will become one of the trend of future engine technology.
At present, two stage turbocharging has become the focus of discussion of technology booster, including two stage turbocharging (consisting of two and a small turbocharger), turbo supercharger + type, and can greatly enhance the rise of the engine power and torque at low speed, low engine start to solve the problem of insufficient power to improve the performance of the engine, has a great help.
It is understood that the foreign vehicle and related parts enterprises have adopted and studied the two stage turbocharging technology, with high technical maturity. The public will be the first turbocharged and supercharged two types of double engine turbocharging system application in production models; the new Infiniti 3.0LV6 twin turbo engine "VR30" was officially put into operation; Berg Warner continue to promote two stage turbocharging technology (R2S); Honeywell launched the new two stage turbocharging system with two different size of VNT turbocharger. But there are not many domestic high level turbocharger enterprises. Hunan Tianyan invested 4 million 150 thousand yuan in 2015 to carry out research on two stage turbocharger project. At present, 1 projects passed customer performance test. In general, domestic enterprises in the two level turbocharging technology level is not high, facing great challenges.
Direct injection engine emission upgrade "new catcher": gasoline engine particulate trap (GPF)
The direct injection gasoline engine (GDI) in cylinder has been widely used in passenger car because of its good power and fuel economy. However, due to the direct injection of fuel into the cylinder of the GDI gasoline engine, the uneven mixing of oil and gas and the wet wall of the fuel make the mass and quantity of the particulate matter significantly increase.
More and more stringent regulations require a direct injection of a gasoline engine to maintain a stable and low PM emissions in a wider range of conditions. The European VI emission regulations are more stringent on the quality of particulate matter, and the PM limit is reduced to 4.5mg/km. Recently released light vehicle emission limits and measurement methods (the sixth phase of China) also tightened the PM limit requirements, the first stage is 4.5mg/km, and the second stage will be 3mg/km. Although GDI engine technology is progressing, it is difficult to meet the needs of emission regulations upgrading solely by internal purification. Therefore, gasoline particulate filter (GPF) is considered to be the most effective and reliable potential technology to deal with GDI gasoline particulate matter emission limits.
At present, the newly released industry directory of foreign investment (Revised Draft) will transform diesel particulate trap into particle catcher, which means that diesel particulate traps will also encourage foreign investors to invest in GPF. Foreign parts enterprises such as BASF, Faurecia and so on in the study of GPF technology and has been applied in the market, the Volkswagen Group announced in June 2017 will be gradually in the overall popularity of GPF gasoline engine. In fact, many companies develop GPF strategy, but not officially announced across the board layout, domestic enterprises take the GPF line, and your research Weifu and other companies also have the technology, compared with foreign technology gap. With the gradual advancement of emission regulations, the future GPF is expected to become a standard.
The future of new energy vehicle driving technology: hub motor technology
New energy vehicles and traditional cars is not a small difference in the drive mode, mainly driven by a motor, including permanent magnet synchronous motor, motor, wheel hub motor, the hub motor technology is considered to be a new energy driving technology in the future, with broad prospects for development.
