The CFD Analysis of Exhaust Runner for GW15 Gasoline Engine

Abstract:

In order to improve GW15 gasoline engine’s power and economy, AVL BOOST/FIRE software has been applied to the simulation of the engine’s one-dimensional and coupled 1D-3D simulation. First, optimal length of exhaust runner was obtained by simulation with BOOST, and proposed two types of structures schemes. Then, the better one was selected for BOOST and FIRE coupling in order to further optimize the exhaust runner according to the numerical simulation results. Finally, the engine performances were verified through experiment. The results indicate that both the engine’s maximal torque and maximal power increase, specific fuel consumption decreases.
