Optimized Design And Flow Characteristic Of Intake System For 469Q Gasoline Englie

Intake system play an important role in engine, its structural parameter has significant effect on charging efficiency, inlet gas uniformity, movement of gas mixture and process of combustion, which contribute to the performance of power , economical efficiency and emission behavior. Therefore, the design of intake system, which is one of the key for engine technology ,play an important role in exploitation of engine. Good array of structure for intake system contributes to air-in naturally, while structural parameter of gas handling system preferred properly can make engine make use of inlet gas' dynamic effect and raise intake efficiency, in order to make engine operate stably in wider speed range.Three-dimensional numerical simulation was carried out through the software of CFD, flow characteristic inside intake system could be understood and grasped. It is very significant to design intake tube shorten the periodic time of product designing and manufacturing. Nowadays, numerical simulation of inlet gas mainly was applied to flow field from aditus larynges...
