| Abstract:Aiming at the existing problems of air inlet units for natural gas engines, a new kind of inlet unit featuring double anti-surge valves was designed, which effectively reduced the vibration of the air inlet system, improved the transient response performance of engines and avoided surge, thus prolonged the service life of engines. Through CFD flow field analysis and relative experimental verification, the air inlet unit is demonstrated to be feasible, and have realized mass production. |
