Open column: The industry discussion triggered by the controversy over the countdown to the ban on conventional fuel trucks was tentatively scheduled for 2017. However, my article entitled "New Consensus Created by Wan Gang's Commanding Sounding Internal Combustion Engine Industry" once again raised a heated debate. Feedback, we found that we all agree that the internal combustion engine will still play a role in the mainstay of the point of view.In fact, from the second half of last year, many industries, "big guys" and technical experts have emphasized this on different occasions a little.
The automotive industry does not give up the internal combustion engine, which is the market choice.It will not only withdraw from the stage of history in the short term, but also will continue to be optimized.Cn engine technology, how to transform and upgrade the next step, to achieve sustainable development? This is the special 'tradition Engine Optimization Road Series covers questions that you want to answer.
The internal combustion engine electrification is the concept recently proposed by Minister of Science and Technology Wan Gang at two important automotive industry conferences.
Earlier this year, Wan Gang said at the 'International Symposium on the Transformation and Upgrading of Traditional Fuel Vehicles' Technology (the 'Symposium') and the 'China EV 100 Forum' (2018) that the integration of internal combustion engines and electrification is the future of automotive New direction of development of power technology.He thinks, in addition to the technical innovation of internal combustion engine itself, should also focus on the technical innovation of the integration of internal combustion engine and electrification. "The internal combustion engine exists in the form of independent drive or hybrid and has a wide market demand. 'Wan Gang said.
Exploring the electrification of internal combustion engines has never stopped
The concept of internal combustion engine electrification is based on the traditional internal combustion engine is in the critical period of transformation and upgrading and industry re-think of the development of new energy vehicles.
Xing Min, secretary general of China Internal Combustion Engine Industry Association, told reporters that the internal combustion engine has long been a highly intelligent product, such as high pressure common rail injection system and aftertreatment system, etc. Yao Chunde, deputy director of Tianjin University's State Key Laboratory of Combustion Engineers, also said: In fact, the internal combustion engine industry has long been studying, but did not focus on this concept.Electronically controlled injection, variable timing, start and stop, direct injection, turbocharger, exhaust gas recirculation, hybrid, 48V Are all technologies that result from the integration of internal combustion engines with electrification. It can be said that China's internal combustion engine industry has been doing research and development on internal combustion engine electrification and has never stopped. "
"Electricization of internal combustion engines is not new." Wei Anli, a member of the China National Internal Combustion Engine Industry Association, concisely expounded the intent of electrification of internal combustion engines: 'It is mechatronics.'
The engine industry usher in the critical point
For quite a long period of time, especially in the areas of passenger transport, large freight transport, large shipping and large-scale agriculture, the internal combustion engine has a vast market demand either independently or in hybrid form. "Wan Gang pointed out that the internal combustion engine will Improve fuel efficiency and reduce emissions as the main line, focusing on the areas of high-strength complete machine technology, high-performance key component technology, advanced combustion technology, low friction technology, low power consumption accessories, light weight and afterheat energy utilization and post-treatment technologies Scientific research, with a view to China's transport sector energy-saving emission reduction, climate change to play an important role.
Internal combustion engine is a high thermal efficiency, high power density, and high adaptability of oil products.Xin Min told reporters that the internal combustion engine not only will not withdraw from the stage of history, but also more and more broad prospects for development.He stressed that at present The internal combustion engine technology is at a critical critical point. The first is that the thermal efficiency of the internal combustion engine is expected to increase further to 50%. The second is that the internal combustion engine under the national emission standard will approach zero emission and the internal combustion engine is already a high-end smart product. Thirdly, with electrification With the depth of internal combustion engine integration, its performance and efficiency will continue to improve.With the arrival of the critical point, the internal combustion engine industry to do a lot of things.In the next few decades, the internal combustion engine is clearly irreplaceable.He said.
All along, energy-saving emission reduction is the primary task of China's internal combustion engine industry.Xin Min told reporters that, in addition to improving product thermal efficiency, the internal combustion engine industry in China has been advocating the development of diversified fuel combustion engines, and actively study alternative fuels such as methanol, ethanol, combustible ice and so on Good progress has been made.
'At present, there is a certain gap between the technical level of internal combustion engines in our country and that of foreign countries, but we have not imagined such a big gap.' Wei Anli said that at present China's internal combustion engine processing equipment has been very advanced, which could have been introduced. However, some technologies can not be bought, The gap is gradually reflected in the internal combustion engine electrification, EFI technology, variable timing, exhaust gas recirculation, fuel injection and other technologies are mostly in the hands of foreign-funded enterprises.With the acceleration of emission upgrades, engine calibration work is also by AVL, FEV and other foreign countries Engine technology companies are doing, the gap seems to be widening again.
Wei Anli expressed his feelings to reporters: 'In the internal combustion engine technology, there is a big gap between our country and the foreign advanced level. We have been trying hard to narrow it down and the industry should not widen the gap again due to the deviation. After all, our foundation Not solid .Scientific research and development of the real estate industry there is no shortcut, we must be down-to-earth, to lay a solid foundation of the challenge.He worried that in the absence of obvious basic advantages, blindly promote the development of electric vehicles, the marginalization of the internal combustion engine industry, if One day the world's advanced internal combustion engine technology to enter the Chinese market, we will not parry.
Competition and optimization among different technologies and their combinations opens
In September 2017, Fu Yuwu, then chairman of China Society of Automotive Engineers, made it clear at an industry conference: 'It is a big thing to ban fuel tankers, and history is responsible for both the government and the industry. The government should be cautious on the issue of banning the sale of fuel trucks and follow the scientific laws. "He said that China's auto industry development strategy must, at the top level, be compatible with the country's energy strategy. The national energy strategy is very clear: Diversification is still the basic point of our energy strategy, and if we simply understand 'new energy' (automobile) as 'electrification', this description or direction is not complete. "Fu Yu-wu Said in his opinion: 'If in the future the HEV (hybrid) + EV (electric) + PHEV (fuel hybrid) + fuel cell road map is good, I believe that all businesses can accept. We should face up to hybrid This is a technical route that can not be circumvented.
Henan Universal Purcell New Energy Technology Co., Ltd. Deputy Managing Director Han Guangxin told reporters that if from the battery power practitioners point of view, of course we hope that the rapid development of the market, forcing the performance of batteries and other key components to improve.But from another Angle of view, continuous optimization and upgrading of internal combustion engine technology can also promote electric vehicle cooling down, only overcome the key technical difficulties, the electric car can develop more stable.
Is there any contradiction between the development of new energy vehicles and the development of traditional fuel trucks? This is a question that deserves serious consideration from the automotive industry. Not long ago, the CEO of AVL specifically sent us a speech at the seminar, stating: 'We need What is done is to successfully reduce CO2 emissions by continuously increasing the efficiency of powertrains, and competition and optimization of different technologies and combinations of internal combustion engines have been initiated under this trend, such as internal combustion engine electrification, hybrid power, fuel cell Power etc.
