In mid-March 2011, accompanied by a clear roar of the motor, the DPCC 490-IV diesel engine was successfully fired at one time in the laboratory of the company's technical center, marking a significant step towards the DPRK 4A series diesel engine sprint IV. Steps. With the continuous demand for improving the environment in the world, China's environmental protection requirements for automotive products are getting higher and higher. In order to meet the strict restrictions on future automobile emission regulations and adapt to the market, Chaochai has established a 490-country IV engine R&D project. Since the project was finalized, all the technical personnel of the development team have been actively involved in the development of the product, from the determination of the program, the feasibility analysis, the establishment of the platform, the drawing of parts and components and the production to prototype assembly, and the hard work of technical engineers. Sweat finally got the joy of success. Hard work pays off, and the ignition of the 490 Country IV engine succeeds, signifying substantial progress in this work and preliminary verification of the preliminary matching design. The next step is for technicians to start with the combustion system, post-processing system, and electronic control system to fully optimize performance and emission indicators, and to calibrate the engine and vehicle parameters, and strive to complete the development of the 490-country IV engine as soon as possible.
