In recent years, the country’s requirements for diesel engine emission standards have been continuously increasing, requiring diesel engine manufacturers to have strong technology research and development capabilities and innovation capabilities. Yuchai is the location of the National Engineering Laboratory for High-efficiency, Energy-saving and Environmental-friendly Internal Combustion Engines with the highest level in China's internal combustion engine industry. It is also the most comprehensive internal combustion engine manufacturing base for domestic product spectrum and the most comprehensive leading product category for domestic excavator products. In January 2013, the media research and interviewing group entered the Guangxi Yuchai Machinery Group Co., Ltd. and conducted on-site research and interviews about the little-known technical hard power behind this “green power capital of Chinaâ€.
Building a multidimensional technology platform
“Yuchai, as a national high-tech enterprise, has provincial-level engineering and technology research centers, state-level enterprise technology centers, post-doctoral research stations, and national accredited laboratories and CCS certification.†Yuchai Engineering Research Institute Vice President Tan Dahui said, “We have established close technical cooperation relationships with well-known R&D institutions at home and abroad. We have formed a powerful R&D platform that focuses on our own R&D technology, connects to the world’s cutting-edge technologies, levers external forces, and services internal. Technically, it is always in sync with the world's advanced level."
Yuchai currently has three major research and development technology platforms. The first is the core technology platform for diesel engine structural design; the second is a clean and efficient diesel engine combustion development platform, which realizes “high-pressure injection + post-treatment control = continuously upgraded emission technologyâ€; and thirdly, it establishes diesel emission control that meets the needs of China's specific market. Technology, established a diesel engine electronic control technology development, application, matching and calibration technology platform, and realized remote control technology based on engine electronic control technology, wireless communication, and internetwork.
Build a first-rate technical team
“In addition to strengthening the construction of its own innovative R&D platform, Yuchai has also extended its cooperation to strengthen the technical exchanges and technical cooperation with universities and research institutes at home and abroad through the 'school-enterprise' cooperation method. The company is used annually for research, production and research. Special funds of more than 50 million yuan have greatly promoted the research of basic technologies, key technologies, and forward-looking technologies,†said Guo Deming, deputy party secretary of Yuchai, who told reporters.
Yuchai currently has 2,630 engineering and technical personnel, 90% of which are professional technical personnel with a bachelor's degree or above, and 50% are middle and senior professional titles, which is much higher than the industry average. Among them, top-level and high-end talents include: 5 people enjoying special government subsidy from the State Council, 11 national-level technical experts, 1 expert of the “Automotive Development Advanced Technology†key project of the National Science and Technology Ministry’s 863 program, and 3 professor-level senior engineers. There are 5 postdoctoral fellows, 26 PhDs, and 156 senior engineers. Yuchai's technical team covers professionally multi-disciplinary fields, staffing is scientific and reasonable, professional fields cover a wide range, has a solid theoretical foundation, and has long-term work in the front line of product development, production and technical services, and has rich practical experience and is first-class in the industry. Automotive Diesel R & D team.
Maintain leading technical strength
In terms of engine product R&D, Yuchai participated in the formulation and revision of four national standards, presided over the formulation of one industry standard, and possessed four core technological capabilities such as “combustion development, electronic control technology, mechanical development, and power system matchingâ€. European-European emission control technology, hybrid powertrain technology, two-stage supercharging technology, air hybrid technology, combustible gasoline combustion technology, simulation technology, post-processing technology, and many other leading new technologies.
In terms of technological innovations in domestic automotive powertrain systems, Yuchai has achieved five brilliances: the first to support domestically-made systems, the first to apply electronically-controlled combination pumps to the concept of medium and light diesel engines, took the lead in putting on after-sales diagnostics, took the lead in automating calibration, and pioneered and promoted Heavy-duty diesel engine SCR technology promotes scientific and technological progress in the industry and improves the competitiveness of the industry.
In the research and development of construction machinery products, Yuchai has five mature technology of “hydraulic sensing, confluence control, refueling, holding valve, and linear traveling valve technology†and “streamline and animal simulation are the mainstream appearance design and intelligentization. Electronic Control System" and other advanced technologies.
In the aspect of research and development of technological innovation products, annual research investment accounts for more than 3% of sales in 2005, and annual sales of new products account for more than 40%.

Creating extraordinary technical achievements
Yuchai currently owns 1,026 patents and is the most authorized unit in the industry for filing patents. Among them, the use of casting residual heat stress relief aging heat treatment process, aluminum alloy diesel engine block casting mold and casting method, diesel engine four-valve cylinder cover gravity casting mold and manufacturing method, vermicular graphite cast iron casting method, cylinder head air core fixing method, etc. Five patents for invention have filled the technical gaps in the whole country and the whole industry. The patent of the "four-valve diesel engine cylinder head unloading groove" has broken through the technical blockade of foreign engine companies.
From the realization of the country to the European engine emission standards, Yuchai was implemented two to seven years ahead of the national standards respectively. In 2011, Yuchai successfully developed the first vehicle diesel engine in China that meets the European standards for emission standards (the national standard will be launched in July 2013). The 4.6 millionth engine and the 30,000th new energy engine were successfully off the assembly line, the first in China. The single-cylinder power 500kW medium-speed diesel engine NY9320 was completed.
In 2012, Yuchai released new products for heavy-duty high-speed ship electric engines, which are integrated with the world's four leading internal combustion engine research institutes and have independent intellectual property rights, namely 12VC, 12VT and 8C.
Innovation is a magic weapon for Yuchai to improve its core competitiveness. Technological innovation and technological hard power have enabled Yuchai to stand at the vantage point of the industry and have achieved a brilliant annual growth rate of 30% in Yuchai's ten years. The 2011 sales revenue exceeded the 400 billion mark, highlighting Yuchai's efforts in the internal combustion engine industry. Chinese creativity.
