In September 2010, Chaoyang Diesel's new CY4102-CE4B engine appeared in the 32nd Environmental Protection Bulletin of the Ministry of Environmental Protection's State IV, becoming the first domestic engine to achieve environmental protection announcements using the same EGR technology route. The 4102 two-valve series of three models and 4D two-engine engines also appeared in the 34th batch of National IV Type Approval Certificates. This signified that all new products of Chaochai Company IV have obtained environmental protection announcements. Become the manufacturer of heavy national IV diesel engine with the largest number of models in the industry to obtain the environmental protection announcement of the route.

Due to the rapid development of the automobile industry in China, the consequences of automobile emissions on environmental pollution are becoming more and more serious. To protect the environment and improve people’s quality of life, some key cities in China, such as Beijing and Shanghai, have already implemented national IV emission regulations in advance. The provincial government also issued government documents and clearly stated that starting from September 1, 2010, the implementation of the National IV emission standards in the Pearl River Delta region, I believe that with the needs of environmental protection, there will be more cities and regions will implement the national IV emissions regulations Therefore, obtaining an environmental announcement becomes a necessary condition for the engine to enter the market.

According to the management requirements of the Ministry of Environmental Protection, the engine obtained the environmental bulletin to complete the plan filing, issue a report, report online, review, publish the verification draft, and finally issue an environmental protection announcement. The most important one is the record of the product plan, and the so-called plan record Equivalent to the technical route of the engine and the production conformity assurance measures of the company have been approved by the Ministry of Environmental Protection. Only after the record is approved can the follow-up declaration of the engine environmental protection announcement be made.

The new product of China IV developed by Chaochai Company is based on a comprehensive consideration of the cost control of the whole machine, product development speed, and market application. The technical staff boldly innovates and adopts technologies that are different from those of most of the national IV heavy-duty diesel engines. The route belongs to the domestic first technology route. Because it is the first product of the route, the R&D process is full of challenges. There is no ready-made experience for reference. Everything needs to start with the most basic work. In the face of difficulties, R&D personnel have developed detailed and feasible solutions to the emerging problems in the R&D process. The solution has overcome technical difficulties such as oil adaptability and post-processing matching, and has achieved a series of research results.
