During the "Eleventh Five-Year Plan" period, in order to respond to the national energy-saving emission reduction call, Weichai Group has achieved rapid development and performance of the economy through continuous technological innovation, increasing the technological content of products, developing circular economy, and strengthening energy conservation management. The powerful combination of sustainable development and social responsibility. Promoting Energy Saving and Emission Reduction by Independent Innovation Innovation is a key factor in the successful development of Weichai Group. Since 1998, Weichai Group, a traditional state-owned enterprise, has carried out all-round and systematic innovation in the areas of operation system, business model, technology research and development, and internal management, and has embarked on an intrinsic development path relying on independent innovation. Through technological innovation, the company's product line has been developed from medium-speed diesel engines to full-scale development of medium- and high-speed diesel engines, achieving a shift from a single market to a diversified market; high-speed diesel engines have expanded from a single supporting heavy truck to ancillary construction machinery and large passenger vehicles. Ships and power generation. Among them, the high-speed machine entered the 50-loader market and realized the upgrading of China's construction machinery power; with the successful matching of luxury passenger cars of 12 meters or more, it changed the long-term dependency of imported luxury cars in China. According to statistics, during the “Eleventh Five-Year Plan†period, Weichai Group has cumulatively developed more than 50 new products and successively successfully developed high-speed high-speed diesel engines that meet the national III, National IV, and National V emission standards and have completely independent intellectual property rights. The main technical indicators are in line with the international advanced level. Among them, the Blue-Rising III engine, which is currently supplied in large quantities in the market, is more than 15% more fuel-efficient than similar domestic products. According to industry association statistics, the use of Weichai engines can achieve annual fuel savings of more than 4,800 liters per year when each commercial vehicle is operating 100,000 kilometers. If calculated by one million vehicles, it can save nearly 5 million tons of diesel a year. In 2005, faced with the fact that the performance of the engine itself has been very limited, Weichai Group has taken the lead in presenting the concept of commercial vehicle powertrain and has become China's only powertrain provider through industrial integration. "After the system is optimized and matched, the vehicle R&D efficiency of the assembly of Weichai Powertrain will increase by 30% and the fuel consumption will be reduced by about 10-15%," said the person in charge of the Weichai Group Technology Center Powertrain Research Institute. In 2009, with the approval of the Ministry of Science and Technology, the strategic alliance of China's new energy and power industry for commercial vehicles and construction machinery was established by Weichai Group. The alliance aims to develop a series of core technologies featuring electric power and electronic control through independent innovation and establish a common technology platform for hybrid powertrains for commercial vehicles and construction machinery. Through the development of two hybrid powertrain assemblies used in six fields including hybrid power loaders, excavators, bulldozers, large passenger vehicles, heavy-duty trucks, and military vehicles, China's commercial hybrid power technologies have reached international advanced levels and achieved industrialization. . After the products are mass-produced, within the scope of technology application, the “3×30†comprehensive index can be achieved, which can increase fuel economy by more than 30%, emissions by 30% or more, and manufacturing costs by less than 30%. “At present, the number of gas engines produced by Weichai has reached 25,000 units and the emission reduction is more than 60,000 tons,†pointed out the person in charge of Weichai Group's Westport New Energy Company. At the same time, during the “11th Five-Year Plan†period, Weichai developed 1,710 kinds of special accessory products, and the proportion of new product output value to total output value rose from 45% at the end of the “Tenth Five-year Plan†to the current 58%. Weichai also successively presided over and Participated in 10 national "863 projects" and scientific and technological research projects, obtained 577 patents for product and technology authorization, and completed 18 new product identifications above the provincial level. At the end of 2009, Weichai Group was honored by the China Enterprise Confederation as the first batch of “independent and innovative model enterprises†in China. Recently, Weichai Group was awarded the third batch of "National Innovation Enterprise" by the Ministry of Science and Technology. Develop circular economy and strengthen energy conservation management In addition to complying with industry development trends and increasing the technological content of energy-saving and emission-reducing products, Weichai Group has achieved a win-win situation of social resources and sustainable development of enterprises by actively developing circular economy and strengthening energy conservation management. During the “Eleventh Five-Year Plan†period, the Weichai Group’s engine production was close to 2 million units, an increase of 177% over the “Tenth Five-Year Plan†period. However, the company’s energy saving amount reached 334,000 tons of standard coal, and the comprehensive energy consumption per million output value was 0.0513 tons. Coal/ten thousand yuan, compared with the "fifteen" period decreased by 63%. Eliminating outdated, high-energy-consuming technologies and equipment promotes energy conservation and emission reductions. During the “Eleventh Five-Year Plan†period, Weichai Group invested more than RMB 5 million, completed the elimination of three coal-fired boilers with a total tonnage of 10 tons, and put on two new gas-fired steam boilers with 6 tons and 4 tons respectively. Section of more than 280 tons of standard coal, effectively reducing the smoke and dust and sulfur dioxide emissions. Invested 37 million yuan, installed a system of power-saving devices, energy-saving rate of 12%, saving more than 4 million kwh per year. In the lighting system of the newly-built industrial park, Reese lighting power saving control device was installed, saving more than 13% of electricity without reducing the internal illumination of the workshop. Invested more than 200 million yuan to install frequency conversion devices in the air compressor station, saving more than 14%. In each production plant and each energy network, frequency conversion speed control devices are installed through feed pumps, and the energy saving rate reaches 20%. In the enterprise casting system, by installing an automatic temperature control two-stage gas automatic burner to eliminate the "reactive" waste of gas consumption, the furnace gas consumption is effectively reduced. Replace traditional metal halide lamps with LED light sources, saving more than 65% of electricity, and saving more than 23 million kilowatt hours of electricity annually. The recycling of industrial wastewater is a long-term and long-lasting task for Weichai to protect the ecological environment and implement a circular economy. In the old plant area of ​​Weichai Group, Weichai built a wastewater recycling system with a daily treatment capacity of 4,400 tons. All industrial wastewater was brought into the wastewater station and realized a “closed-circuit cycleâ€. This system recycles more than 100 tons of waste oil annually, reducing industrial wastewater annually. 1.2 million tons of emissions, annual water reuse more than 1.5 million tons, 1.5 million tons of water. In the new industrial park built during the “Eleventh Five-Year Plan†period, a wastewater recycling and reuse system with a daily processing capacity of 1,000 tons was constructed. The advanced technology of separate pretreatment and re-integrated treatment was adopted, and 360,000 tons of recycled water was used annually. 36 million tons of fresh water. After being treated and reused by the enterprise, Zhongshui is widely used in the production and life of trial-cycle water, production process water, toilet flush water, and fire-fighting water for large-series diesel engines, which reduces fresh water consumption and improves the environment. Reduced pollution. Actively implement energy-saving technological reforms and continuously tap energy-saving potential. Weichai Group has effectively adjusted the layout of steam pipe network distribution, updated pipe network insulation materials, and continuously optimized the structure of the steam pipe network to ensure that the company’s steam losses continue to decrease, based on production demand and steam supply and consumption status. During the “Eleventh Five-Year Plan†period, it invested nearly 2 million yuan to implement automatic frequency conversion transformation of industrial boilers, and implemented automatic adjustment and transformation of water supply and temperature for exchange stations, with a saving rate of 30% and a coal saving rate of 8%. For each energy system pipe network, special funds are invested every year for major repairs or technical reforms to prevent all kinds of energy from “running, running, dripping, and leaking.†One of the detected and rectified diesel pipes leaks, and the annual reduction of diesel losses is more than 400 tons. . During the “Eleventh Five-Year Plan†period, Weichai Group established four new industrial parks in Weifang, covering more than 3,000 acres. Weichai places special emphasis on the energy conservation and emission reduction infrastructure of new projects. Taking the foundry industrial park as an example, in accordance with the principles of “sustainable development†and “recycling economyâ€, low-energy, energy-efficient production facilities are fully selected in process design, and waste heat is used. The use of technology to install high-temperature flue gas waste heat recovery system, steam condensate recovery system, the implementation of waste heat, residual energy recycling, effectively reduce the park heating steam and natural gas consumption. Among them, 80 tons of hot air oxygen-enriched cupolas, castings with an overall scrap rate of 1.8% or less, 220 tons of coke per ton of castings, 47,000 tons of coke per year than the domestic average, and secondary combustion of flue gas through waste heat utilization technology. The temperature of molten iron reached 1500-1550°C, and the melting efficiency increased by 45%. The recycling rate of waste sand was over 85% through the old sand recycling technology. With the technology of fully-sealed bag dust removal, the dust removal rate reached 99.8%. In the processing industrial parks, we attach great importance to the basic construction of energy-saving and emission-reduction and all use low-energy and energy-saving equipment to ensure the energy utilization of the new park is optimal. In 2008, China's auto parts remanufacturing pilot work was officially launched. As one of the 14 pilot companies, Weichai became the first batch of “crab-eating people†and began its own exploration journey. At present, with the characteristics of Weichai products, Weichai Group has invested 1 billion yuan to introduce a complete set of remanufacturing processes, equipment and standards from Europe and the United States. It has built a high starting point, specialized, and large-scale engine remanufacturing base, and designed annual production capacity in the first phase. 20,000 units.
