During the Yutong Bus Technical System visit, Assistant Director Dong Xiaokun of the Test Center found a summary of the 2005 meeting. According to the minutes, Yu Tongxiang, president of Yutong Group , had already put forward a task that must be strictly fulfilled for the technical system: to effectively and efficiently carry out energy-saving and emission-reduction work for vehicles, and to achieve domestic leading and international follow-up. This request was proposed to be three years ahead of the deadline for domestic passenger car emissions from Euro II to Euro III. It has been four years ahead of the "Yutong Cup" that has impacted China's road transport industry vigorously... “Tom Tang made a forward-looking plan for the energy saving and emission reduction work of the technical department at the then meeting. Now, when he comes back to it, he feels that the thinking is still leading.†Dong Xiaokun said in an interview: “Yutong Cup†It is an all-round display of Yutong Bus's energy-saving and emission-reduction work, which is backed by Yutong’s persistence and commitment. Yutong started to grasp the foundation in 2003, and it clearly put forward energy conservation and emission reduction targets in 2005, and then there is a step by step Execution has only achieved success today." In 2009, the first “Yutong Cup†motor vehicle driver energy-saving skills competition in the national transportation industry ignited an upsurge of energy-saving and emission-reduction work in the bus industry. At the summing-up and commendation conference, Minister Li Shenglin commented that “this is an active and effective transportation industry. Energy conservation and emission reduction grand meeting.†Behind the praise is Yutong 's transformation and innovation, sweetness or bitterness. Start by saving the first drop of oil The rapid development of Chinese passenger car technology has mainly focused on recent years. Before 2000, few people could imagine the achievements of the domestic passenger car industry today—compared with the global mainstream passenger car brands, and achieved the world's largest passenger car production base. At that time, the most demanded needs of passenger cars were reliable and durable. “Energy saving and emission reduction†sounded far worse than “buses can run†and it is not the most pressing demand of the market. But in that era, Yutong began the next stage of researching and planning customer appeals at the time of its rise. Regarding how to effectively and efficiently carry out the work of energy saving and emission reduction for passenger cars, Dong Xiaokun said: “Our approach is to analyze its root causes, start with saving the first drop of oil, and find out the key to energy conservation and emission reduction. How to generate fuel combustion The transformation of energy into more efficient kinetic energy drives is the focus of the Yutong Technology Department's research and is also the difficulty." "The 'engine thermal management system' is one of the results Yutong has made over the past several years. Many people misunderstood the 'engine thermal management system' as an electromagnetic clutch fan. It is actually very one-sided." Dong Xiaokun said: "The engine heat “Management system†is a set of technical structures that can increase the conversion efficiency of thermal energy and involves various aspects such as transmission system optimization, aerodynamics, and fluid dynamics. In simple terms, how to convert heat energy into vehicles more effectively through technical means The driving energy is the core of 'engine thermal management system'." Since saving the first drop of oil, Yutong has found a reverse path for energy conservation and emission reduction of vehicles. Thousands of things, make everything simple Technically achieving the energy-saving and emission reduction of vehicles is a "from scratch" process. Prior to this, the bus industry did not have much research in this area. Initially, Yutong was able to conduct basic research on some desks by collecting data. "When we research more about energy-saving and emission reduction work, the more we find the factors to be taken into consideration are very complicated. This is a very large system project." Yan Beizhan, Yutong's first postdoctoral station doctor station, Over the past nine years, he has been responsible for the fuel consumption improvement work of the vehicle. In an interview with the reporter, he said, “For example, the temperature control of the engine, the most ideal state is at 80°C-90°C. At this time, we must consider the control of the fan and the engine compartment. The structural design, the optimization of the intake and exhaust systems, etc. For example, we can improve the economic performance of the vehicle through the lightweight of the vehicle body, once the treatment is not good, the strength of the vehicle body is prone to problems, and if there is a problem with the strength of the vehicle, The noise will also increase.... Any single enhancement of any performance will affect the change of other performance. In order to ensure that the overall performance of the vehicle can be smoothly delivered to the market, we must consider more.†With the completion of the Yutong National Test Center and the introduction and application of basic experimental equipment and basic research tools at the international advanced level, research on energy saving and emission reduction has been gradually deepened. After numerous trials and demonstrations, Yutong has simplified the energy-saving technologies and achieved success. Yutong attributed the fuel economy influencing factors to 12 major items: engine itself, intake system, fuel system, cooling system, exhaust system, transmission system matching, engine accessory consumption, air conditioning use, tire selection, vehicle body resistance And key points, vehicle driving and maintenance, fuel and lubricant quality. At present, Yutong’s technical evaluation system for vehicles has been basically completed. For each product's performance planning, comprehensive evaluation will be conducted from 16 dimensions, and doing a good job of energy-saving and emission reduction of vehicles is only one of the 16 dimensions. From textbooks to the steering wheel With the continuous deepening of research on energy-saving and emission-reducing vehicle technologies, Yutong found that the driver's operating technology level has a great impact on fuel consumption. To make energy-saving and emission-reduction work, it must be considered in a comprehensive manner. “We have found in practice that the same vehicle type runs the same line, and the fuel consumption of the vehicle is very different when operated by different drivers.†During the special research that was responsible for reducing fuel consumption for several years, Yan Beibing often visited with equipment. Customers around. Years ago, Yutong specifically summed up a comprehensive set of “fuel-saving driving tips†and issued it for many drivers. From the actual results, though effective, the effect was not obvious. "If the data is not quantified, many drivers will still be accustomed to driving according to their own experience. It is really not easy for them to change." Dong Xiaokun said: "So we thought about how to infuse things on the 'textbooks' to them. In my head, it turns out that the fuel-efficient driving competition supported by advanced equipment is a very good way to promote." “In the promotion and training of the initial activities, a short distance of 30 kilometers, the gap between the driver's fuel consumption training before driving the same vehicle reached more than 2L. Many users are very interested in this phenomenon, which also prompted us to More research is being conducted on how to guide drivers to regulate safety-saving fuel-saving driving skills.†Previously, “Value forever†campaigns have been used to interview users in various regions. So after summarizing the basic methods of safety fuel-saving driving operations for passenger cars, Yutong’s technical department began to broaden its horizons and made them more detailed. For example, for special environments, specific driving methods for night driving, mountain driving, and passenger taxiing have been proposed; for season changes, summer driving and technical requirements for preventing driving punctures have been proposed; for different vehicle types, summary The technical requirements for safety and fuel saving of driving buses and buses have been issued. For road conditions, corresponding methods and requirements have been given under the conditions of passenger car turning, passenger car uphill, passenger car intersection, and passenger car transfer. Dong Xiaokun said: "We can do more to make users save more on fuel economy." postscript: From the realization of energy-saving emission reduction value, the improvement of technology is undoubtedly a very important significance. In light of the future work of energy saving and emission reduction, Dong Xiaokun said that “Yutong is ready for the preparation of Euro III to Euro IV and plans to fully realize it by the end of 2009. The technology reserves for some alternative energy and new energy buses have also been improved. Planning." At the same time, in Yutong’s opinion, practicing energy conservation and emission reduction is not only a technical issue, but also a number of projects involving management, technology research and development, and marketing, and it is an all-round energy-saving and emission reduction. In terms of management, the company adheres to the concept of sustainable development, integrates the objectives of environmental protection into its production and operation management, actively promotes technological progress, and uses environmentally friendly raw material production to ensure the unity of economic and environmental benefits. Through the management assessment, some high-energy-consuming facilities have undergone technological transformation, and a series of measures have been taken from energy management to improve the operating efficiency and the effective utilization of fuel oil, gas, and coal, and to achieve pollution reduction and efficiency enhancement, environmental protection, and production and management. Simultaneously develop and implement social responsibility for environmental protection and sustainable development from the source and process. Uncovered lid “In the past, there was very little systematic quantification of the concept of energy conservation. Whether vehicles are really energy-efficient and whether driving skills can actually help vehicles save energy are nothing like stuff in the pot. No one really knows. 'Yutong Cup' is like unveiling this lid, allowing more people to see and clearly feel the internal link of energy saving, which helps users to see the development of bus technology more rationally, and thus to promote greater The spread and use of the scope. †At the time the train was first researched, it was not yet fast, but now the speed of the train has exceeded 300km/h, which is the absolute mainstream mode of transportation. The same is true for passenger cars. Although alternative energy and new energy products are not yet mainstream in the market, these technological reserves are very necessary for the future. 6.0-7.0KW Porable Gasoline Generator 6.0-7.0KW,High Quality 6.0-7.0KW,6.0-7.0KW Details, Fujian Jinlongteng Power Engine And Machinery Co., Ltd.

“A lot of old drivers had good driving skills before, even years ago they were already models of fuel saving in their own units. However, the technology of passenger cars has changed so much now that many traditional methods are no longer applicable. Driving by experience is not enough. Drivers also need to adapt to changes in technology.†Dong Xiaokun said, “For example, many drivers used to think that air glide was fuel efficient, but now that neutral driving is not allowed, and even air glide is not Besides, in the past, many drivers liked to use speed gliding after the vehicle accelerated, but now the vehicle technology is the most economical when the vehicle is driving at a constant speed... It is necessary for the driver to understand the changes of these technologies in order to help them really Cars are well opened and the energy conservation and emission reduction work is put in place."
From the summarization of the “fuel-saving driving tips†to the “priceless†competition and the nationwide promotion of the “Yutong Cupâ€, Yutong transformed the driving methods of the driving skills from the original “textbook†model to the driver’s own operation. The effect of the "steering wheel" to feel the pattern is far beyond imagination.
