With the escalation of emission standards and the engine itself, the piston must constantly be adjusted and improved in terms of design and manufacturing, which has brought a considerable challenge to the piston industry. On the morning of September 5th, the Central Media’s implementation of the “four industries in the country” took the first stop in the second quarter of grassroots research activities to the Shandong Binzhou Bohai Piston Co., Ltd. (hereinafter referred to as the “Bohai Pistons”), and investigated the four-engine piston industry. Preparation situation. Lin Fenghua, chairman of Bohai Pistons, said in an interview that the implementation of the National IV standard is not only a problem but also a greater opportunity for the Bohai Pistons. After many years of research on the technology, the Bohai Pistons have advanced technology in the refinement of pistons, and are fully able to meet the requirements of batches of four products.

National IV products are already ready
"As early as 7 years ago, the Pistons of the Bohai Sea began to jointly develop the Fourth National Product with major OEMs. Currently, the powerful OEMs can produce the National IV products. The R&D technology of the Bohai Pioneer IV product has long been completed and can meet the volume requirements. Demand for the country's four products," said Lin Fenghua.

For the heavy commercial vehicle and diesel engine market alone, as the implementation of the National IV standard will increase the user's use cost, it is expected that the National IV standard will show a low tide after full implementation. However, this does not mean that the Bohai Pistons have stagnated. Lin Fenghua said: “The Bohai Pistons track the development trend of international engines in real time and develop new technologies for the Pistons. They have strong capabilities in terms of product reliability, product reserves, upgrading, and processing equipment. Now waiting for the state to implement the four national emission standards, We are fully prepared and the Bohai Piston has been supplied with batches of the National IV products of major domestic diesel engine manufacturers such as Weichai, Yuchai, Xichai, and Dongfeng Cummins."

Adhering to the strategy of producing one generation, one generation of reserves, and one generation of research and development, the Bohai Piston continues to develop the technology of the National Fifth and Sixth National Diesel Engine Pistons while mass producing the four-engine piston of the country. Lin Fenghua told the reporter: “In 2013, the Pistons of the Bohai Sea began to develop the Sixth National Products simultaneously with Weichai, Yuchai and other OEMs. The six-engine pistons have been successfully developed. Among them, the pistons we supply to Cummins globally are Euro 5 products. Just when you were visiting, you should have seen our newly introduced automated production line, which produces the five European products for Daimler-Benz."

Lin Fenghua frankly stated that the Bohai Pistons are now developing piston lightweight construction, low friction, wear technology, high-performance aluminum alloy materials, ceramic composite materials, and piston surface low-friction coating technologies in accordance with the requirements of upgrading the engine to higher emission standards. And practice.

Market mourn for prepared companies

“When Beiqi Futian Shangguo Fourth’s products, we and another competitor carried out the development of Guosi’s products. At present, all of their national four engines use the products of Bohai Pistons. Because of the opportunity to prepare companies,” Lin Fenghua told reporters. In an interview, Lin Fenghua said: “This is a case where there are too many Pistons in the Bohai Sea. Take Cummins as an example. If you want to enter their R&D system, parts and components companies must have the ability to develop with them simultaneously. This is a lot of domestic Parts companies don't have the same. Daimler Benz is also the same, we participated in the research and development of their five new European products in the early stage.Besides, the cooperation with the public still needs to be intervened early, and our R&D must be synchronized with them, so we entered the world of Volkswagen. Supply system.” He explained that both at home and abroad, the Bohai Pistons have the ability to develop in parallel with the host plant. Therefore, every upgrade of emission standards is an opportunity.

R & D and production strength

As a leader in the piston industry, the Bohai Pistons has always insisted on the road to continuous innovation and development. According to Lin Fenghua, currently all Bohai Piston production lines use advanced and mature technologies at home and abroad to achieve automatic loading and unloading and automatic feed channel connections. In the R&D team construction, the team now has 157 people, including 4 PhDs, 14 researchers, 46 senior engineers, and 8 foreign experts. The R&D center is equipped with piston design, computer-aided analysis, experimental center, and materials research. , process research, surface coating technology research and other 13 research and development departments. In the face of domestic and foreign customers, the R&D center has also established 10 research and development groups. Each team directly provides technical services to customers and is responsible for the piston structure design, follow-up test tracking, and piston optimization and improvement.

At present, the piston production capacity of the Bohai Sea ranks first in the single factory of the same industry in the world, and the domestic comprehensive market share is 35%. The domestic market share of high-end products for commercial vehicles reaches 60%. Its leading products have been supported by many famous host companies such as China FAW Group, Dongfeng Group, Weichai Power, China National Heavy Duty Truck, and Guangxi Yuchai; foreign markets are located in North America, Europe, East Asia, and the Middle East, with Cummins and Caterpillar. , Volkswagen, Fiat, Kohler and other international high-end customers.
