When it comes to JAC Navistar , what is your first reaction? Users may think of Jianghuai Automobile , which has a glorious history for more than 50 years, or the enviable United States Navis , which was once envied with penny paper money. The "K-series" trucks are expected, but it is estimated that few people will know the Maxwell Force (MAXXFORCE) that Jianghuai Navistar is proud of. Indeed, for a Sino-U.S. joint venture engine plant that has been in production for just three years, MAXXFORCE's products can be described as “maintained by people who are not well-knownâ€, but in the past two years, they have relied on JAC and Navistar. Leading technology and the complete vertical supporting system of Jianghuai Commercial Vehicle Co., Ltd., Maisifu power has been exposed, and the future is bound to set off a new competitive pattern in the domestic diesel engine market.

On October 26, 2015, Jianghuai Navistar, which had been in production for a year, invited more than a dozen domestic commercial vehicle media to approach the birthplace of MAXFORE (MAXXFORCE). China Truck Network was also invited to visit this beautiful Chaohu Lake. The engine factory on the edge. Since the reporter had previously visited the engine factories of domestic joint-venture brands and independent brands, coupled with the previous experience of working in the engine factory, in fact, they did not hold too high expectations for the visit of the Jianghuai Navistar factory. They were nothing more than being ahead of schedule. Clean up to show you hello. The actual situation was unexpected. The intelligent, automated, and digital level of this new generation of diesel-powered "super factory" was much higher than my previous expectations. It should be one of the best-known domestic joint venture brand engine plants!
900 times higher than the hair thin standard processing accuracy and manufacturing quality
Entering the JAV Navistar factory first gives people a feeling of closeness and ease. It may be because of my past experience that I recall a lot. Even the smell in the air is more affectionate; but more is production. The tidy and comfortable environment of the workshop brought a group of media people to admire the excellent environment of the factory. It is not only the appearance of comfort, according to the staff, the factory used the most advanced ground source heat pump air conditioning system and station air supply device, air can be circulated in the depth of 100m underground, and then sent to various stations, can be achieved The four seasons of constant temperature inside the factory can't help the reporter to regret it. If he could work in a comfortable factory like Jianghuai Navistar, he wouldn’t resign because of the cold winter and summer heat. Of course, the most important thing is that the constant temperature can avoid thermal expansion and contraction. The processing error brought by it ensures the processing precision and quality of the product.

The so-called "workers" must first sharpen their tools if they want to do good. The engine has the highest gold content in the vehicle's "heart", and its requirements for manufacturing technology and finesse are even better. JAC Navistar clearly has a lot of skill in this area: First is the intelligent operation, and the huge factory sees only a few. People, all components up and down, processing, transmission and testing can be automatically completed, each device has a digital display in front of the operator only need to follow the instructions of the display can be operated, even our "tech white" It can also be completed under the command of the staff under the command of the engine production, its intelligent automation strength is evident.
Each link is digitized and automated to eliminate human influence
Followed by digital processing, the MAXXFORCE 3.2L/4.8L production line we visited has six CNC machine tool processing lines, automatic assembly lines and fully automatic spraying lines with processing accuracy of 1um, among which the reporter has long known High-precision machining equipment such as HECKERT CNC machine tools and NAGEL machine tools from Germany appeared in the cylinder and cylinder head processing line of the Maasfu engine. These most advanced equipments of the moment undoubtedly hit the table. The manufacturing process of Vyster, but also in each process, is also equipped with the Italian MARPOSS intelligent detection station, the detection accuracy of up to 0.1 microns, equivalent to one-900th of hair. After these heavy processing and inspections, each Maasfu engine undergoes two complete machine tests during the assembly process, including one cold test and one hot test to eliminate any possible quality defects. It is also the most demanding testing requirement in the engine industry. This leading digital finishing operation process is the normal in the operation and management of the deputy general manager of Jianghuai Navistar Production and Manufacturing Co., Ltd. Yong Yong: “In terms of quality control, such as some processes that affect product performance indicators, we precision machining, real-time Processing, measurement and adjustment to ensure that 100% of the parts are qualified.†Mr. Yan told the China Truck Network reporter.
On the left is the Marposs test station from Italy, which can detect a 0.1 micron error, which is equivalent to one in 900 hair strands. On the right is a Nagler grinding machine made in Germany. The machining accuracy is calculated in microns.
On the basis of superior standard production quality, JAC Navistar also achieved a super environmentally friendly process concept. The ground source heat pump air conditioning system can achieve a 30% reduction in energy consumption compared to traditional air conditioners. The cooling liquid concentrated circulation system can provide centralized supply of all cooling liquids, centralized recycling, and activated carbon adsorption + greening and cleaning devices in the spraying process. The generated paint waste realizes the environmental protection treatment and truly realizes the green factory standard.
Wait for the engine that sprays antirust paint
The super performance of the factory also validated the action of Jac-Navistead’s General Manager Tony Sutton when interviewed by reporters: “JAC and Navistar have the most advanced Maasfu engine technology and The introduction of manufacturing technology into China not only focuses on the tremendous potential for development in the Chinese market, but also hopes that these high-performance engine products will provide unrelenting momentum for China’s economic development. Therefore, every one of our employees of Jianghuai Navistar is There is a sense of mission. This sense of mission always motivates us to do our best."
Neiyouwai Xiu Jianghuai Navistar is ready
If JAC Navistar lays a solid foundation for the production and processing capabilities of MAXXFORCE products with comparable world-class super factories, then the product itself leads the same level of technical strength and complete vertical matching of JAC commercial vehicles. And the service system is an important weight for Jianghuai Navistar to win the market in the future and to achieve excellence within the show.

In terms of product performance, Yang Qingrong, deputy general manager of Jianghuai Navistar, explained to us in detail that the mass production of the Maisford 3.2L and the Maisford 4.8L engine each has its own merits. Maisford 3.2L engine is the gold power of domestic light trucks, and its product performance is also gold strength. The product is equipped with the mainland high-pressure common rail system. Compared with the injection pressure of 1600Bar, the injection pressure can reach 1800 Bar, fuel atomization. The effect is better, the engine is more fuel-efficient, and the standard Honeywell double-shaft variable-section turbocharger, which injects new vitality into the Maasfu engine, is more timely and more rapid than the ordinary turbocharged power reaction. . And Mai Sifu 4.8L is also outstanding, the product has superior reliability and low noise performance, can achieve a low engine output torque of 1200r/min rare light engine, and the lower the speed, the smaller the friction loss, Product reliability naturally increases.
What is the performance of such excellent engine products in the market for one year? How should we cope with the increasingly fierce market environment in the future? As early as September 25 last year when the new factory of the Jianghuai Navistar was completed, we established clear objectives. From 2014 to 2018, it will use five years to supply 70% of the engines of the Jianghuai light, medium and heavy trucks. Although only 600 Maisfor power products were delivered last year, Jianghuai Navistar is confident that the company will plan to produce 5000 sets of JAC trucks from next year through full market validation and product performance feedback. It will start mass production on a large scale, fully supporting JAC Shuai Ling , Chun Ling Light Truck, Vesta Zhongka and Geerfa K6 series products. Not only that, but also Jianghuai Navistar will also focus on the domestic and export markets, in the future will actively rely on product advantages and JAC strength to achieve more sales.
At the same time, in terms of product line construction and customer service requirements, Jianghuai Navistar also tried its best to continuously enrich. According to Tony Sutton, general manager of Jianghuai Navistar, the Maisford Power (MAXXFORCE) another killer 7.2L product will also be mass-produced in late summer and early autumn next year. watch for. Regarding the after-sales service capabilities of the products that the users pay attention to, the Jianghuai Navistar adopts the JAC vehicle service network. Under the support of nearly 1,000 JAC service stations, it can achieve a full service radius of 50 kilometers. Spare parts and JAC vehicles Built, the user car has no trace of worry.
