Business spirit
Assistant General Manager of FAW Jiefang Company, Party Secretary and General Manager of the Engine Division Qian Hengrong has always insisted that “Xichai brand does not consider joint venture cooperation, independent products do not consider technology introductionâ€, and it is also because FAW Jiefang Engine Division (hereinafter referred to as the Business Department) Constantly bravely climb the peak of new technology, fully capable of positive innovation, especially in the research and development of the national six engines, the business department with technology innovation as the core, has become "China to create a core benchmark."
Be the first to apply advanced technology to improve product performance
Product performance plays a decisive role in the corporate brand, especially in the engine industry. Improving product performance is a systematic project that covers the entire product development cycle and requires a complete set of reliable solutions.
In order to comprehensively improve product performance, the division actively promotes technological innovation by integrating its own high-quality innovation resources and innovation drive capability, and is the first to apply laser-welded all-steel piston technology to further reduce piston friction power consumption and reduce power. Loss, power output is smoother, power and torque are improved significantly, not only in fuel economy, but also in power output. This technology not only reduces the height of the cylinder, but also reduces the weight of the engine, especially in the light weight of the whole machine. Not only that, but the technology greatly improves the quality of parts and components, and the reliability is higher, which effectively reduces the risk of engine failure, and the performance of the whole machine is more excellent in stability and durability.
Independent research and development of new technologies to improve fuel economy
As we all know, the engine of the business department has one of the most remarkable features compared with other brands of engines in the market. It is fuel-efficient. This is inseparable from the business department's research on engine fuel-saving technology. Of course, the products of the business department are upgraded in the national five. In policy orientation, I have never forgotten my own "old business."
In order to achieve better fuel economy, the division formed a project team in early 2018, based on the CA6DL6 engine platform, to develop an asymmetric turbocharger with independent intellectual property rights. After one year, in February 2019, the test bench data showed that the performance of the self-supercharger parts reached the latest level of similar foreign-funded products, the high-speed fuel consumption was equivalent, the low-speed fuel consumption was greatly reduced, and the asymmetric turbocharged project was also obtained. The industry experts agree and highly appreciate.
Division's independent intellectual property rights asymmetric turbocharger products
The mainstream route breaks through and has high environmental value
The forthcoming National Sixth Emission Standards Policy is not only the key work to win the blue sky defense war, but also the development vane of the engine industry. The Division is committed to providing innovative and practical power solutions to meet the diverse needs of customers and environmentally friendly technologies.
Under the strict requirements of the national six emission standards, the business unit adopts the international mainstream technology program EGR+DPF+SCR. The scheme has the advantages of mature and lower cost. The hot-end EGR technology combined with the independent intellectual property rights of the business unit, combined with the single-channel hot-end control valve, improves the uniformity of the exhaust gas in the air, effectively reducing the generation of NOX and solving The technical problem of the hot-end EGR valve system applied to medium and heavy-duty commercial diesel engines; combined with DPF technology, captures and contains harmful particles, preventing the engine from emitting tiny and toxic particles, which eliminates the troubles caused by the urea system. The exhaust emissions are cleaner and have higher environmental and social benefits.
Encourage talent innovation to promote efficient development of enterprises
Workers must first sharpen their tools when they want to do their best. For the enterprise, this device is the talent innovation. In order to improve the innovation ability of the staff of the business department, on March 30, 2019, 40 senior directors and directors of product research and development participated in the first innovation achievement sharing meeting.
The first session of the Innovation Achievement Sharing Conference
The Innovation Achievement Sharing Conference provides a new learning platform for employees, fully mobilizes employees' enthusiasm for innovation, strengthens the application of cutting-edge technology applications, researches and develops innovation hotspots, focus and difficulties, and completes the wisdom sharing and experience inheritance of innovation results to enhance the innovation ability of R&D personnel. At the same time, it helps to apply cutting-edge knowledge points to future work. At the same time, it draws on some successful examples for analysis and research, enhances technological innovation capabilities, and promotes talent innovation in the business sector.
Innovation is an important starting point for promoting creation, and creation is the key to achieving value breakthrough in China. It can be said that there is no innovation and no creation. Facing the rare opportunity of the new national industrial revolution and the transformation of China's development mode, the business department promoted industrial transformation and upgrading through technological innovation, seized the opportunity of the national six era, and became the national high-end power leader. In the future, the business department will continue to adhere to technological innovation to promote national creation, realize innovation as soon as possible to create a "core" change, and strive to become China's first, world-class engine supplier.

Manufacturing method
Spiral steel pipe is a strip coil as raw material, often warm extrusion molding, automatic double wire double buried arc welding process of welding and the spiral seam pipe.
(1) raw material that is strip coil, welding wire, flux. Have to go through strict physical and chemical tests before they are put into the investment.
(2) strip head and tail docking, using single or double wire submerged arc welding, the steel tube rolled by automatic submerged arc welding welding.
(3) before molding, the strip passes through the leveling, trimming, planing, surface cleaning and conveying, and bending and handling. (4) using the electric contact pressure gauge to control the pressure of the cylinder on both sides of the conveyor, to ensure the smooth delivery of the strip.
(5) the external control or internal control roll forming.
(6) using the welding gap control device to ensure that the weld gap to meet the requirements of welding, pipe diameter, the wrong side of the amount and the weld gap are strictly controlled.
(7) welding and welding with the Lincoln Electric welding machine for single or double wire submerged arc welding, so as to obtain the stable welding specification.
(8) the welding seam after welding is through the online continuous ultrasonic automatic inspection, to ensure that 100% of the spiral weld nondestructive testing coverage rate. If there are defects, automatic alarm and spraying marks, the production workers at any time to adjust the process parameters, timely elimination of defects.
(9) the air plasma cutting machine to cut a single pipe.
(10) into a single tube, each batch of steel tube head to strict inspection system first, check the weld mechanical properties, chemical composition, blending, surface quality of steel pipe and after nondestructive inspection, to ensure that the pipe manufacturing technology qualified, can be formally put into production.
(11) in the weld on the site of continuous acoustic inspection marks, after manual ultrasound and X ray review, if there are defects, after repair, once again after the non destructive testing, until the defects have been eliminated.
(12) strip butt weld and intersecting and spiral seam D connector tube, all through X ray TV or film examination.
(13) each pipe is tested by hydrostatic pressure, and the pressure is sealed by radial seal. The test pressure and time are strictly controlled by the steel pipe water pressure computer testing device. Automatic print record of test parameters.
(14) the pipe end machining, the end verticality, accurate control of slope angle and blunt edge.
