(六)进气和排气系统1.进气导管与4缸和6缸汽油发动机不同,8缸汽油发动机采用双管式进气系统,如图9所示。因此在任何负荷范围内均可向发动机提供所需空气量。谐振器:主要在进气导管内降低活塞式发动机的脉冲式换气噪声。赫姆霍兹谐振器作为技术解决方案可在确保最大空气导管横截面和最小安装空间的情况下满足车辆特定减震要求。2.热膜式空气质量流量传感器
(Vi) Intake and Exhaust System 1. Intake Duct Unlike the 4-cylinder and 6-cylinder petrol engines, the 8-cylinder petrol engine uses a dual-tube intake system, as shown in Figure 9. Therefore, the engine can be supplied with the required amount of air in any load range. Resonator: Reduces the pulsation noise of piston engines mainly in the intake duct. Helmholtz resonators serve as technical solutions to meet the vehicle-specific damping requirements while ensuring maximum air duct cross-section and minimum installation space. 2 hot film air mass flow sensor
