Recently, China's first self-developed V-type 12-cylinder engine, CA12GV, was successfully ignited at the technical center of China FAW Group Corporation. This indicates that China has mastered the development technology of the top passenger car engine.
The technical center of First Auto Group Corporation undertakes the research and development of FAW commercial vehicles and passenger car engines. Its engine research and development is at the leading level in China's auto industry. In recent years, the company's independently developed 6DM, 6DL, 6DF, 6DE, and CA6DL series diesel engines have taken the lead in the country. The ignition V12 engine is an air-injected all-aluminum engine. It is a fully self-designed, internationally advanced petrol engine developed by FAW Group for the new HQE Dahongqi and is also the first independently developed top-level gasoline engine in China. Passenger car engine. This engine not only has a number of new technologies and new structures for the first time in China, but also reaches the advanced level of similar products in the world. It is the independent development of passenger car engines following the JB8 engine and gasoline direct injection (GDI) engine in FAW Group. Another breakthrough achieved.
According to reports, the CA12GV engine has seven advanced technologies and features. Advanced Combustion System: Combustion system can meet the requirement of airway injection and gasoline direct injection in the cylinder at the same time, which lays the foundation for the direct upgrade to gasoline direct injection engine in the future. Main and auxiliary ECU (engine control unit) joint working technology: Using CAN (Controller Area Network) bus technology to make two ECUs work together to achieve precise control of engine performance, emissions, and vehicle-related systems. Dual VCT (Variable Convex Energy Timing): Through the precise optimization of the valve timing, the best fuel economy, dynamic performance and emission performance are achieved. Three-layer silent chain drive: adopts a silent chain structure with the lifespan of the engine to achieve the best timing system NVH (vibration, noise and comfort) performance. All-aluminum lightweight design: All-aluminum cylinder block, cylinder head, housing parts and brackets are used to analyze the topological structure through FE to achieve the best balance between light weight and NVH performance. Advanced NVH structure design: Fully benchmarking, combined with experience design and modal calculation, special design for noise, such as cylinder block, cylinder head, crankshaft, valve chamber cover, timing chamber cover, oil pan, etc. The overall modal calculation of the powertrain determines that the vibration node is designed for suspension to ensure the noise performance of the vehicle. Compact structure: By adopting the advanced TOP-DOWN (top-down design method) and three-dimensional synchronous design, a compact engine structure is achieved, and cabin space is minimally occupied.
Industry experts believe that through the development of this engine, FAW Group has mastered the key technology for the development of the V-type engine. It is difficult to make it easier for the first time, laying a solid foundation for the next step in the development of V6 and V8 engines. It is reported that according to the FAW project planning process, the V12 engine will be put into mass production in April 2009, providing power support for the high-end red flag sedan - HQE level platform products.
