| Abstract: | On the integrated optimization plat,the workflow of intake system optimization was constructed based on Boost which is the software of engine cycle simulation.The model was verified by experiments.At the declared speed,the design variables are geometric parameters(intake pipe length,pipe diameter,volume of resonator) and spark advanced angle,AF rate.The engine torque and fuel consumption rate were optimized by using the DOE tests.The results showed that the length of intake pipes has a special influence on ... |
