With its own brand into the R & D of electric vehicles is different from the multinational car prices in the development of new energy vehicles generally relatively steady pace, on the one hand to step up research and development related technologies, on the other hand is also glimpsed the market changes in the independent brand 'embrace' new energy vehicles At a time of tide, multinational car companies are still continuously introducing internal combustion engines with higher thermal efficiency.
Toyota announced that it is working on a completely new engine and transmission at the end of 2016. According to the plan, nine new engines will be available in 17 different versions from 2017 to 2021. The new engine achieves a thermal efficiency of over 40% and the latest TNGA platform from Toyota All models will be equipped with all and will form a series of products.In addition to Toyota, with the Japanese car prices Mazda announced in August this year, in 2019 will launch an ultra-high compression ratio and the use of ignition pressure ignition gasoline engine , And said the traditional engine is still at the core of the long-term strategy of Mazda.Analysts pointed out that in the independent brand competing to launch new energy vehicles strategy, seemingly about to give up the internal combustion engine vehicle products, we must note that the international technology for internal combustion engine R & D and energy extraction is growing.
'Today we focus on the development of new energy vehicles and smart car Lianxiang, but we should not forget the traditional cars and conventional internal combustion engines, this area is still an important innovation platform.' Chun Wah Capital Chairman Wang Da-heng said that once in the United States GM to achieve the highest management positions of the Chinese people, has been commissioned by Xu and Yi as general manager of BAIC Group .Wang Da total that, despite the momentum of the development of new energy vehicles, but traditional cars and conventional internal combustion engines still have considerable room for improvement and potential to dig .
Electric vehicle energy efficiency to be observed
Five Tsinghua University scholars in the "Applied Energy" published in "China's electric vehicles and diesel locomotives, greenhouse gas emissions," a paper pointed out that 'compared with traditional vehicles, electric vehicles equipped with completely different propulsion system, the car production Related energy consumption and greenhouse gas emissions may change significantly.Electric vehicle production process produces energy consumption and greenhouse gas emissions by about 50% higher than diesel locomotives.This huge change is mainly due to the production of power batteries, and this is Key components of electric vehicles In addition, the weight and weight distribution of the materials used in EVs can also have a major impact on the environment through the development of new power battery technologies, vehicle recovery and low-carbon energy Structure to improve. 'The article believes that at this stage because the technology is not mature, recycling has not yet been completed, the energy consumption of electric vehicles is not dominant.
Looking at the current electric car products on the market, some enterprises in order to pursue a higher driving range, only a substantial increase in the number of batteries, resulting in increased vehicle weight, a large number of battery energy consumed by the battery itself, contrary to the electric vehicle energy saving The original intention of some high-performance electric vehicles, limited edition electric super run, no more than the internal combustion engine car energy saving, Tesla had because of high energy consumption by the Singapore government fined.
Electricization is the inevitable trend of automobile development and also the only way for automobile energy saving and environmental protection.At present stage, due to the proportion of China's energy structure is still biased in thermal power generation, electric vehicles are still unable to evade the environmental pollution caused by coal-fired power generation.China Internal Combustion Engine Industry Association Deputy Secretary Wei long said that China's automobile and engine industry after 20 years of development, the gap with the international advanced level has been reduced from 20 to 3 to 5 years if one-sided pursuit of leapfrog, blindly to zero emissions as the goal, irrationally Ignoring the fact that the proportion of thermal power in China's primary energy structure is as high as 75%, neglecting the reality of the single structure of China's national power grid, ignoring the current situation of the huge industrial structure of fuel vehicles and internal combustion engines in our country, pursuing the development of a single electric vehicle (pure electric vehicle) In the end I am afraid there will be no electric car to achieve the lead, the traditional energy vehicles and internal combustion engines have been opened up the gap.
Yin Chengliang, director of the Innovative Center for Electric Vehicles of Shanghai Jiao Tong University and vice president of Automotive Engineering Institute of Shanghai Jiao Tong University, said that giving up an internal combustion engine car in the short term will only be worth the candle. Discontinuing ICE car products may cause a large number of independent brands to give up or reduce the number of engines Technology and components on the R & D investment, resulting in increased disparities between China and foreign. 'In the absence of a power source to completely replace the internal combustion engine when it must not take this one loss because of the small loss for the hundreds of thousands of new-energy vehicles on the order of magnitude, Loss of 20 million orders of the traditional car market, the loss of engine technology to catch up with the enthusiasm and investment. "Yincheng Liang said.
Internal combustion engines still have potential to dig
Gu Le Lin, executive vice president of Shanghai Automotive Lin that 2030 years ago, the internal combustion engine can not be replaced by the car, then the dominant market will remain the internal combustion engine car.Also similarly expressed the views of the other Sensen Technology Co., Ltd. President Xin Jun.He said 80% of the world's automobiles will be internal combustion motor vehicles by 2030. Many core parts still deserve further exploration by their own brands. China's core parts and components industry is not strong, and the purchase price can not be competitive. Its own-brand research and development The effect of the product can not be faster than the cross-border car prices.
'Now the mainstream international view is that from traditional car to new energy vehicles, but also after a minimum of ten or even 20 years of transition time, and this change is gradual. The first step, the transformation of traditional cars, the use of 48V hybrid system; the second step, from weak mixed into strong mixed, such as Toyota's Corolla and Camry, the basic performance and cost are done and traditional cars at almost the same level in accordance with the development of this step can reach 100 km in 2020 5L Fuel efficiency standards. "Chengdu Wyatt EFI limited liability company general manager Zhu Yuanxian told the" China Auto News "interview, said he believes that electric cars really take the place to replace the fuel truck for a long time, through the development of hybrid technology can Achieve energy-saving goals.
Maizu 'Chi Chi blue sky' technology is the man who see the light husband said that in Japan, by improving the internal combustion engine can easily exceed the environmental indicators of electric vehicles, while in the main thermal power in China, electric vehicles are not environmentally friendly. 'If the gasoline vehicles are The replacement of electric vehicles will pose a huge challenge to the power grid and power.In the future, as the environmental protection of power generation increases, the cost of solar and wind power generation will be directly reflected in the electricity bill, and the economical use of electric vehicles Will face the test.Only in the huge amount of low-power conditions, the environmental protection of electric vehicles is feasible.
Internal combustion engine research and development should not be relaxed
According to statistics, currently on the market in the sale of models, the fourth-generation Toyota Prius equipped engine thermal efficiency reached 40%, basically representing the highest level of the tenth generation Honda Civic 1.5T engine, the thermal efficiency of 38%, the public The thermal efficiency of the EA211 series engines is about 37%; the Chery and Changan engines in their own brands are relatively advanced in R & D, the former has a thermal efficiency of 38% in the latest generation of engine research and the H16GB engine in Chang'an has achieved a thermal efficiency of 36% China's own engine level has been close to the international advanced level.
After many years of chase, from a poor second to the shoulder to shoulder with the multinational car prices, independent research and development of the engine brand in the difficult road ahead, has made considerable progress.Suzhou Technical Director Xu Zheng said: 'We have more than five years of efforts to make The power system of the entire self-owned brand has made great strides, and our products are comparable in the market to the joint-venture brands. Now suddenly the market orientation has changed. All the centers of gravity and resources are tilted toward the field of new energy vehicles. Concerned about the engine and transmission, I think, can not be stopped lightly research and development of traditional cars, the current product layout is very clear, even after 10 years on the market 60% to 70% of the products or equipped with engine, so the engine must be a problem And under Part VI standards, particulate emissions from some new energy vehicles are even greater than the emissions of conventional fuel vehicles.
Xu Zheng said that its own brand of traditional fuel vehicles and new energy vehicles, the development process is full of hardships for generations.From the market development in the next decade, the traditional fuel trucks will still dominate, and therefore vigorously promote At the same time, we should not blindly stop the development of key technologies of traditional fuel trucks and hope that both national policy and industry orientation should be considered in all aspects, with a focus on guiding the pace of rhythm and creating a more stable environment for the development of the industry.
