Gold product chain drives Weichai to diversify from a single diesel engine supplier
On December 20th, Weichai Group celebrated its sales revenue by more than 40 billion yuan, and also held a new product display. A product that was dubbed the "Blue Engine Powertrain System" was placed in the center of the exhibition hall. Everyone stops to watch. From its combination we can see the shadow of today's domestic heavy-duty commercial vehicle parts gold industry chain: Weichai Power 11.6 liters WP12.375N turbocharged intercooled electronically controlled high pressure common rail diesel engine, rated power 276 kilowatts (1900 rev / Sub-), maximum torque 1800 Nm (1000~1400 r/min), minimum fuel consumption ≤185 g/kWh, emission index in line with national 3/European standard III; Fast 12JS180T transmission, rated input power 331 kw, each Speed ​​ratio 15.53~1.0; Hande MAN single-speed reduction bridge, rated load 13 tons, transmission ratio 3.7.
It was known to the reporters who were introduced by Weichai Power Technicians that this is where Weichai has integrated its European R&D centers, AVL vehicle R&D centers and other technical resources, and has leveraged the technical advantages of well-known experts from domestic and foreign industries to focus on Weichai Power in Weichai Group's systems. The technical elites of Fast, Fast, and Handecar lasted six months and spent more than 20 million yuan to complete the power system design. Wei Dehui, deputy general manager of Weichai Power and director of the Technical Center, introduced that this powertrain product has undergone rigorous matching tests and demonstrations. It has performed outstandingly in all aspects of data, and has been able to perform in terms of dynamics, economy, and reliability. The best power system solution in the domestic automotive industry. It is understood that the introduction of this system is not only the first in China, but also the technical content and product quality are in an internationally leading position.
In the powertrain, the matching blue-engined 3N series 1900 rpm engine has achieved four breakthroughs in technology: First, it is economical. The operation of the 1900-to-N series engine avoids the high fuel consumption area. By reasonably matching the multi-speed transmission and the small-speed ratio axle, while improving the power performance, the common operating conditions of the vehicle are in a low fuel consumption area, which is more economical and fuel-efficient. Followed by power. Torque is increased throughout the low and middle speed range, the corresponding full vehicle power is strong, and the starting acceleration performance is superior, and the engine torque is increased by more than 15% at 800 revolutions. The third is reliability. The rated power speed is reduced to 1900 rpm, which reduces the linear speed of the piston operation, thereby reducing the relative speed of all pairs of movements, improving the mechanical efficiency, and greatly improving the reliability of each moving part. The overhaul period of the engine exceeded 1.2 million kilometers. The fourth is environmental protection. Compared with the 2200 rpm engine, the 1900 rpm engine can effectively reduce the engine noise by 1 dB and its emission performance is significantly improved.
Speaking of the cooperation between the various teams on the powertrain project, Weichai Power's CEO and Chairman of the Fast Group Li Dakai said that many teams within the group worked together and did a lot of technical matching work, such as the best The speed ratio, the best arrangement, the best geometry, etc., have done a lot of work even in terms of noise. When a reporter asked about the significance of this kind of technical cooperation, Li Dakai said with some emotion that as a whole, our resources can be shared, and the general engine manufacturers would have reservations about its core technologies such as electronic communications, and would not be willing to pay To the transmission plant, but we are a strategic alliance with Weichai. We are not only strategic alliances on products, but also strategic cooperation in capital. Everyone is unanimous and will undoubtedly make things better and of course save them as well. A lot of time and money.
For the significance of the introduction of the Weichai Lanqing Powertrain system, Tan Xuguang, chairman of Weichai Holding Group, said that this module, integration, and individualized innovative ideas have made significant changes to the product structure of Weichai. Weichai is no longer a single diesel engine. The manufacturer, but an enterprise group with a powertrain and a diversified product line for commercial vehicles, has rapidly expanded its product chain and industrial chain, bringing more benefits to the company while satisfying users' greatest needs.
