"The CA6SM natural gas engine won the award for innovation, the best green design award for China's innovative design, and the successful application of the diesel engine intelligent start/stop technology (START/STOP), and achieved a leading breakthrough in the field of technological innovation in the industry." At the Ninth Science and Technology Conference of China FAW Xichai, a batch of innovations that focused on energy conservation and environmental protection were commended, demonstrating Xichai’s concern and emphasis on environmental protection, energy conservation and emission reduction.
“Xichai Intelligent Idling Start-Stop Technology was successfully put into use on 130 new energy vehicles in Changzhou Public Transport recently, and it has truly implemented 'all-intelligence' for energy conservation and environmental protection.†With the vigorous promotion of national policies and the acceleration of the implementation of the fourth national standard for diesel engines, Xichai has taken the lead in the development of the new energy sector before the two sessions this year. The “autonomous shutdown technology at the time of parking†has made breakthroughs in phases. When the red light or parking is on, the engine will automatically turn off, and the engine will be immediately started when the accelerator pedal is stepped on again or the brakes are lifted off. This makes it energy-saving and environmentally-friendly.
“Equipped with the Xichai Aowei engine, the fuel economy is more efficient, and the fuel consumption per 100 kilometers is 2-3 liters less than that of similar models.†People clearly remember the “China FAW Commercial Vehicle†sponsored by FAW Group a few months ago. In the 'Oil Masters' - Fuel Saver Master Challenge, the Liberated J6 11-liter tractor equipped with Xicave Aowei’s machine has created excellent fuel consumption of 100 kilometers under the guidance of fuel-efficient experts. 24.4 liters of industry record. In recent years, Xichai has focused on technological innovation as a strategic focus. While speeding up emission upgrades, Xichai also maximizes vehicle fuel-efficient maximization. Among them, the “Diesel Diesel Engine Load Intelligent Identification Fuel-saving Control Method†breaks through the fuel economy bottleneck of diesel engine electronic control development. This device combines with key technologies such as GPS, EGR and engine braking, making Xichai the only one of the diesel engine industry The key technology companies in the field. At the same time, the "Diesel Engine Cylinder-Off-Cylinder and Fuel-Efficiency Control Method" and "START/STOP Technology Research Project" have all established the technical advantages of Xichai Electronically Controlled Diesel Engine in fuel economy.
“The three Aowei engines, transmissions, and drive axles used in the J6 pilot version were all replaced with 100,000 kilometers of lubricating oil, and the warranty standard was increased to 300,000 kilometers in 3 years, eliminating the need for users.†Xichai passed Its engine combustion, lubrication, oil supply and other systems are optimized. The advanced manufacturing process is adopted to improve the machining accuracy of components. The maximum torque is increased by 10% compared to the original product, and the engine oil change period is extended to the longest 100,000 kilometers. Saves maintenance costs and time.

Full "core" upgrade creates a new era of green power
Needless to say, the integration of environmental protection elements into engine technology research and development is an inevitable trend for people to pay more attention to the living environment. It is synchronized with the concept and is in sync with development. It is imperative to open up the sky and see the fog.
As early as 2006, Xichai invested heavily in the development of the National IV, and used high pressure common rail + SCR and high pressure common rail + EGR + POC dual technology route. The newly-developed Xicai four series products, the combustion system to ensure the efficient and clean burning of fuel, advanced post-disposal device, can effectively remove the nitrogen oxide emissions. Compared with similar products, the major performance indicators of the products are at the international advanced level. Its intelligent motor-driven hot-end EGR system not only solves the technical problems of applying the hot-side EGR valve system to medium- and heavy-duty commercial diesel engines, but also achieves two practical applications such as the control mechanism of the EGR valve on the hot side of the diesel engine and the dual-channel butterfly valve structure. New patent. At the same time, the independently developed Aowei 11LCA6DM four-engine has three invention patents and five utility model patents. Its power, economy, and reliability are in the same position in the domestic same power products. At present, Xichai has formed a full range of "Aowei, Hengwei, Conway" four products, power coverage 78 to 500 horsepower. Among them, Aowei 6DM2 four engines have ranked first in the 11L displacement engine industry for two consecutive years.
Xichai is wise and courageous for the forerunners, and is always on the move. It is dedicated to exploring cutting-edge technologies in energy conservation and emission reduction and has firmly grasped the commanding heights of environmental protection power development. Up to now, Xichai has successfully developed natural gas engines for the four series platforms of F, L, M, and N. The power range covers 170 to 420 horsepower, and a research platform for natural gas engines with independent intellectual property rights has been established. The independent development capability of gas engines not only plugged in the “green wings†for the core power of liberating natural gas heavy trucks, but also became the green engine of public transportation in major cities in China. In Nanjing, which has a reputation as the “6th dynasty ancient capitalâ€, you can see bus buses equipped with the Xichai National Natural Gas Engine racing everywhere. In the beautiful “Ice Cityâ€, a bus equipped with a Xichai gas engine is also available. Speeding through all the golden routes in Harbin; in Pengcheng, the buses of the Xichai natural gas engine and Shenzhen, the city of reform and opening up, have merged into a beautiful and harmonious picture; in Wuxi, a city in the southern city of Wuxi, the street matches Xichai. The bus of the green engine has become the “green card†of this national civilized city...
The data shows that the fuel-saving cost of 100% of the Xichai series of natural gas engines is more than 30%. Compared with diesel engines with the same power, carbon monoxide emissions are reduced by 90%, carbon dioxide is reduced by 20%, hydrocarbons are reduced by 60%, and nitrogen oxides are reduced by 60%.
Green Enterprises Create Green Development Model
Energy-saving and emission-reduction and control of haze production are not only reflected in the production of low-carbon and environmentally-friendly products, but also reflected in the construction of new plants and recycling of old machines.
In 2010, Tin Wood spent a large sum of 2 billion yuan to build a new production base in Huishan New Town in Wuxi. This is the largest investment project in the history of Tin Wood Factory. At the kick-off meeting of the project, Mr. Qian Hengrong proposed the goal of “building a heavy-duty diesel engine production base in Huishan into a model of low-carbon environmental protection!â€. This idea is deeply involved in the entire process of project implementation. Whether it is planning and designing or equipment selection, whether it is the use of energy-saving materials or the application of new processes, people in Xichei will make low-carbon environmental protection an important standard for selection. After two years of hard work, the interior lighting of the unit at Huishan Base adopts the design idea of ​​combining the NGC energy saving device and the natural daylighting belt. According to the existing 544 calculations of overhead lamps, the electricity consumption can be reduced by 5.2 million degrees compared to the conventional lamp source, which can reduce 6.4 Tons of standard coal emissions. The solar heating system was used in the living area, and a total of 146 collective collectors were installed, covering an area of ​​1,200 square meters. The annual electricity saving is about 190,000 degrees, which can reduce the emission of 23.4 tons of standard coal. At the same time, a large number of energy-efficient equipment devices have been used. For example, the school bus line adopts AC power dynamometer power recovery technology, and more than 90% of test vehicle output power can be converted into electricity to realize on-grid recycling. The air-conditioning system uses an efficient, energy-saving, centralized ground-source heat pump system that uses 40% less electricity than conventional centralized air-conditioning systems, and so on. This heavy machine production base covering an area of ​​more than 50,000 square meters has fully achieved the three leading requirements of “Leading Manufacturing Level, Leading Process Equipment, and Leading Quality Controlâ€, becoming a low-carbon and green production model.
"An old engine, after a series of 'old-fashioned' processes, can become an engine with the same performance as the new one, once again becoming the new 'heart' of medium and heavy trucks, and this process can save energy 60%.†In 2010, Xichai responded to the call of the country, vigorously promoted the recycling economy, invested in the establishment of an engine remanufacturing production base in the new district, and made remanufacturing an important means and approach for cleanliness, environmental protection, and energy saving, and became a remanufacturing industry in China. Trailblazers and promoters. The Xichai remanufacturing process is environmentally friendly and efficient. The remanufacturing base is not only equipped with mature equipment for remanufacturing in Europe and the United States, but also has introduced high temperature and water jet cleaning technologies from the United States and Canada. The cleaning process meets the requirements of environmental protection and does not emit any harmful dirt. Air emissions have reached European standards. The entire production process uses the most advanced computer ERP software management system to implement scientific and modern management of the entire remanufacturing process, forming a circular economy model of “resources-products-waste-products-remanufacturing productsâ€.
"Promoting the development of recycling economy and helping energy-saving and emission-reducing development in depth." As a large water company in industrial enterprises, Xichai uses more than 2 million tons of water a year. In order to realize the “zero emission†of industrial waste water, Xichai invested more than 10 million yuan to completely reconstruct the sewage pipe network from the ground to the air. The sewage will be discovered as soon as it “leaks out a dropâ€. At the same time, a reuse water system was also established in the plant area, and a water supply network was laid to reuse 100% of treated water. Sewage treatment rate and industrial water reuse reached 100%. The recycled water is used for cooling production, greening the plant area, flushing the toilet, and so on. According to statistics, now the factory can save 1 million tons of water a year and create economic benefits of more than 400 million yuan.
“Also the city is a blue sky, a clean land for the people.†Xichai will continue to practice green promises with practical actions, focus on green technology, and sing the main theme of energy conservation and environmental protection.
