　　On September 24, 2013, the Chongqing Municipal Science and Technology Commission organized experts to conduct an appraisal of the “R&D and Application of GPL1108D Diesel Engine” project completed by our company. The appraisal committee listened to the work report, the technical report, and the inspection report, reviewed the relevant documentation, and after questioning and discussion, reached the following appraisal opinion:
 
　　I. The submitted materials are complete and comprehensive, meeting the requirements for appraisal.
 
　　Second, in terms of design, by adopting a high-efficiency supercharger, we have increased fuel injection pressure and boosted the mean effective pressure, thereby reducing fuel consumption. In terms of structure, the front-end housing auxiliary system features a tubeless modular design, resulting in a high degree of modularity for the entire machine and making it easy to use and maintain. In terms of manufacturing processes, the cylinder block is machined using a gantry five-sided machining center that completes all operations in a single clamping, ensuring both machining accuracy and the overall reliability of the machine.
 
　　3. Compared with similar domestic models, this engine boasts an average effective pressure that is 10% higher than the average, a fuel consumption rate that is 4.5% lower than the average, and emissions that meet the IMO Tier 2 standards. The engine features high overall robustness, excellent economic performance, strong process compatibility, and outstanding adaptability to various supporting systems. It can serve as a viable replacement for comparable imported diesel engines, holding promising prospects for widespread adoption and delivering significant socio-economic benefits.
 
　　This diesel engine boasts independent intellectual property rights and has been granted one invention patent, 46 utility model patents, and one design patent. The appraisal committee unanimously concluded that the project’s overall technology has reached a domestically leading level and unanimously approved the results of the appraisal.
　　It is recommended to intensify promotion efforts.
