·Exploring Chery Optical Engine Lab: Third Generation Engine

As we all know, in today's highly mature traditional engine technology, it is very difficult to further improve the power, thermal efficiency and economy of the engine, and the direct injection technology in the cylinder is undoubtedly an important technical path, which is also the majority of automobiles. In recent years, companies have developed the reasons for direct injection technology in the cylinder. However, in the development process of the direct injection engine in the cylinder, there was a worldwide problem that the real combustion process could not be visually seen, and the accurate optimization evaluation of the fuel injection system effect could not be performed, thereby optimizing the combustion system strategy. Until the advent of the optical engine laboratory, the problem of visualization of engine in-cylinder combustion was resolved.
Recently, the reporter walked into the first optical engine test room in China, Chery Optical Engine Laboratory, and inspected it in detail and learned its working principle and its irreplaceable role in the development of high-performance engine combustion system. . On June 6th, Chery's third-generation high-performance engine, the 1.6TGDI turbocharged direct injection gasoline engine, which was independently developed by Chery's “V” type product development system, will be officially launched. The optical engine laboratory, as an important part of the Chery “V” type forward development system, played a crucial role in the development of Chery's third-generation high-performance engine combustion system.

As the first automobile brand in China that completely designs, develops and manufactures advanced car engines, the research and development level of Chery Engine has been at the leading level in the industry. As early as 2012, Chery invested more than 10 million yuan and was the first to establish an optical engine test room among domestic auto companies. Thanks to the advanced combustion system development system of the laboratory, Chery's third-generation engine has achieved significant breakthroughs in both power and performance, especially in terms of power, thermal efficiency and advanced component integration technologies. The technical performance level of the first-class brand engine. Its off-line production will enable Chery to maintain its leading position in the engine field, marking that Chery and the Chinese automotive industry have reached a new height in the field of traditional engine technology.

As the current international advanced engine research and development platform, the biggest significance of the optical engine laboratory is to successfully solve the in-cylinder combustion visualization technology of the in-cylinder direct injection engine and lay the foundation for the forward development system of the high performance engine. Chery Optical Engine Laboratory, consisting of transparent single cylinder assembly, laser diagnostic system, boost control system, combustion/emission analysis system, injector spray test system, in-cylinder combustion fiber diagnostic system, and CCD digital/high speed image acquisition The system consists of nine systems, mainly used for advanced engine combustion system development, control strategy development and core component development. The visualization of the combustion process will allow observation of the flow field, spray and combustion processes inside the engine, and the optimization of the fuel injection system through laser-induced fluorescence and fiber diagnostic systems to reduce the risk of oil dilution, match the ignition system, optimize the combustion process and The combustion system strategy, by observing the best match point of the flame propagation path and the diffusion speed in the in-cylinder combustion chamber, finds the optimal injection timing, thereby greatly improving the dynamic performance and shortening the test and verification process of the fuel-saving and emission reduction technology.

According to Chen Guoan, director of integrated development of Chery Powertrain Technology Center, Chery's powertrain technology has been developed from the first generation to the third generation. In the future, Chery's powertrain technology will be able to export including developed countries in Europe and America. The global market participates in market competition with technical performance in line with global market standards. The upcoming launch of Chery's third-generation high-performance engine marks another important breakthrough for Chinese brands in the core technology field, and also marks a solid step for “Made in China” to “Created in China”. At the same time, its downline has laid a solid technical foundation for the future launch of Chery's strategic transformation 3.0 series products.
