On July 4, the National Development and Reform Commission issued the "Opinions on Accelerating the Use of Natural Gas" (hereinafter referred to as "Opinions"). According to the "Opinions", the large-scale and efficient scientific utilization of natural gas in the fields of urban gas, industrial fuel, gas power generation, transportation and other fields will be accelerated. The coordinated development of the middle and lower reaches of the industry will significantly increase the proportion of natural gas in primary energy consumption. Let's take a look at the related content with the car electronics editor.

Therefore, industry experts have said that the release of the "Opinions" means that natural gas will usher in a new "Golden Decade", and the development of natural gas vehicles as one of the clean energy vehicles will also usher in favorable policies.

"Opinions" promote the comprehensive development of natural gas vehicles

The overall objective of the Opinions proposes that gradual natural gas cultivation will become one of the main energy sources of China's modern clean energy system. By 2020, the proportion of natural gas in the primary energy consumption structure will strive to reach about 10%, and the underground gas storage will be effective. The working volume is 14.8 billion cubic meters.

"At present, natural gas automobile engines need to improve in terms of solving high heat and negative pressure and lubricity." Yan Dehui, vice president of Weichai Power Co., Ltd., said in an interview that the construction of natural gas filling stations in China will become the focus of the future. The number of natural gas refueling stations is small, and natural gas vehicles can only travel within a limited range. In recent years, the development of natural gas vehicles has not been as noticeable as pure electric vehicles in terms of policies, and development has always been inferior.

“After many years of research, I found that only natural gas vehicles are the most reliable in terms of energy conservation and emission reduction.” Commercial vehicle expert Yang Zaiyu pointed out that natural gas vehicles emit less particulate matter than diesel vehicles, and the country’s six stages are cleaner. Its economy has made the use of natural gas vehicles as the cleanest energy vehicles in developed countries such as the United States and Europe.

In Yang Zaiqi's view, natural gas vehicles are efficient use of energy. Compared with traditional fuel vehicles, the content of NMHC (non-methane hydrocarbon) in the exhaust gas can be reduced by 70%, CO can be reduced by 50%, and PM can be reduced by 90%. Above, there are no toxic substances such as lead and benzene. In terms of post-processing, natural gas vehicles do not need expensive SCR systems, and it is easier to reach the national five and future national six emission requirements than diesel vehicles.

This time, the "Opinions" support the development of natural gas vehicles from various aspects, which can be said to be highly valued. The "Opinions" pointed out that the development of natural gas vehicles and ships will be accelerated. Natural gas vehicles focus on the development of bus rental, long-distance heavy trucks, as well as sanitation, field, port areas, attractions and other ferry vehicles. Accelerate the promotion of heavy-duty natural gas (LNG) vehicles instead of heavy-duty diesel vehicles in key areas such as Beijing-Tianjin-Hebei.

In addition, the "Opinions" also clearly proposed to speed up the construction of gas filling (Note) station. Encourage the development of CNG filling stations, LNG filling stations, CNG/LNG dual-use stations, oil and gas joint stations, and oil and gas stations in highways, national highways, mining areas, logistics concentration areas, tourist areas, and highway passenger transportation centers. Building stations and so on. In addition, make full use of the existing land in the existing bus station or around the planned construction of the gas filling (Note) station, support the gas station with conditions such as site to increase the gas filling function, and encourage qualified transportation enterprises to build their own gas filling station. .

Sword refers to natural gas engine technology upgrade

Technology is always the core driving force for the development of natural gas vehicles. Therefore, natural gas engines can only win the future if they are technologically advanced. In this regard, the "Opinions" refers to the technological innovation of natural gas vehicles, speeding up scientific and technological research and equipment industrialization. With the combination of politics, production, learning, research and use, we will increase investment in basic research and applied research on natural gas utilization and promote the transformation of results.

The Opinions pointed out that the materials used in the field of natural gas utilization (including high-manganese austenitic steel, Invar, etc.) and equipment (including gas turbines, small gas turbines, fifth-generation high-pressure direct injection engines for vehicles, and large-scale LNG marine single fuels) Engines, etc.) Scientific and technological research and localization, encourage and promote the industrialization of natural gas utilization equipment.

In addition, the "Opinions" also clearly pointed out the development of LNG transportation and vehicle gas technology. Accelerate the improvement of LNG transportation efficiency of water transport, railway and highway, promote multimodal transport, explore the technology and equipment for transporting LNG by container, and enhance the flexibility of LNG transport. Encourage and guide LNG vehicle manufacturers to increase research and development of technologies such as electronic control, engine, gas cylinder and evaporation gas recovery, and improve the operational efficiency of natural gas vehicles.

Based on the above situation, Song Jian, Dean of the Automotive Technology Research Institute of Tsinghua University, said, “In addition to this, the cost of natural gas vehicles will now be solved. With the large-scale production, it is hoped that the cost of gas cylinders for natural gas vehicles will be reduced.”

The above is about the automotive electronics - natural gas vehicle development will usher in a favorable introduction to the policy, if you want to know more information, please pay more attention, electronic engineering will provide you with more complete, more detailed, updated information.
