The United States National Academy of Engineering, the new global GM Tom Stephens, executive vice president at Shanghai Automotive development trend of power —

GM had announced in ethanol fuel technology with the United States energy company Coskata to promote the diversification of clean transport energy technology development. Prior to two-mode hybrid Chevrolet Tahoe and Saturn Aura hybrid, both the debut, but also to show her hybrid technology at the strategic results, GM will also insist the future of hydrogen fuel cell vehicle research and development and adoption of E-Flex System the electric car. Then, in the new energy to the future of motor vehicles on the road, currently in power systems can do about it? Recently in charge of automotive powertrain and product quality of the new global GM Tom Stephens, executive vice president and GM China President and Managing Director Kevin E. Wale in Shanghai in an interview with Chinese reporters, has made a reply.

Reporter: GM made last year, 1.1-liter engine will be the application of SAIC-GM-Wuling vehicles, then the Chinese production of other GM products also benefit from?

Wale: SAIC-GM-Wuling 1.1 liters engine application products, will market the first half of this year. In fact, this is not only an engine, it is a series of engine and platform products. At this platform, we will have a lot of products to the market. Apply the new powertrain the new products, we have introduced a hybrid version of LaCrosse and with six-speed automatic transmission technology LaCrosse. At the same time, the new B series engines 1.2 liters will be on the application of Product at Wuling, this engine can improve fuel economy 20 percent. In addition, with a 2.4-liter engine LaCrosse EcoTEC in fuel economy also has become a national leader.

Stephens: Introduction to the U.S. of these circumstances, not only that we have some good technology, but also shows that our application of these technologies have been doing a good job of preparation, in fact, we have plans to put these technologies in a number of production on larger products, and to put it to China.

Reporter: Universal more advanced ignition direct injection (SIDI) technology, currently only used in a 3.6 liters engine. China and the Asian region for example, 2.5 liters less than the following four-cylinder engine is more practical significance, and that when these technologies will be applied to this type of engine on?

Stephens: Application SIDI our technology not only has 3.6 liters engine, also has a 2.4-liter engine EcoTEC future engines will be applied to more products. Fuel in China is relatively high content of glia, in which the use of environment will not only affect the smooth nozzle, valve will also cause some adhesion. Therefore, the current Chinese fuel quality, the direct application of SIDI technical questions must be.

Wale: China’s oil is indeed a big problem, and this is not a problem by a company be able to resolve, but in terms of the need for more resolve. A direct impact on fuel quality will be the latest technology of foreign companies into China. Therefore, I hope that the Chinese government and Chinese energy companies can quickly take measures to improve fuel quality.

Reporter: GM’s dual mode hybrid technology, is currently focused on products in the SUV, the application will not be at capacity on a relatively small car?

Stephens: Yes, dual-mode hybrid technology is mainly used in large SUV and pickup products, and are basically rear-wheel drive models. However, we have successfully developed the dual-mode front-wheel drive hybrid system and used in smaller products, as well as a number of SUV models on cross. Car products will be applied, at present has not yet been determined, but our car has been developed for the E-Flex system is more advanced, flexible technology, and electric power generation and automotive systems, such as gasoline engines. Application of these systems, it did not need petrol, you can no longer worry about fuel consumption.

Reporter: If the Chinese government introduced a policy to encourage small cars, as the United States National Academy of Engineering academician, you think in this context, what kind of technology easier to achieve higher efficiency?

Stephens: smaller engine displacement is a mainstream trend. To achieve this objective, the general practice is to achieve fuel add turbocharged direct injection of such a combination, it can reduce engine emissions. Therefore, the purpose of our small-displacement engine, as far as possible the use of these products on advanced technologies. In the application of more advanced technology, use of these traditional techniques to make our products more efficient.
