Introduction Study of the flow over car geometries can be performed by numerical simulation．During the recent past，significant progress in the field of computational fluid dynamics(CFD) has also been made，and CFD is gradually becoming established as an efficient tool in vehicle design．The majority of numerical investigations in the field of car aerodynamics have been concerned with grid generation problems around complex three-dimensional geometries，as well as，with the prediction of the aerodynamic coefficients．Takagi [1] presented a review of the applications of computers to automobile aerodynamics, including external flow over car geometries flow in passenger compartments and flow in engine cylinders．Reviews of CFD methods used in automobile aerodynamics have also been published by Kobayashi el al.[2] and Rieger et a1 [3].The research efforts of several other authors in this field can be found in the references of the above review papers．Shaw [4] compared different commercial CFD packages
The objective of the present work is to undertake a complimentary numerical investigation of the flow over a two-dimensional car model.Numerical simulation has also been performed using an incompressible Navier-Stokes code which is based on a pressure-correction algorithm of the SIMPLE-type．

To study the flow and swirl characteristics in the variable swirl intake system of a four-valve diesel engine, a numerical simulation with using the three dimensional CFD software AVL-FIRE, was calculated on the intake flow in three types of inlet of the engine.
So the engine can operate in broader range of the swirl intensity in various conditions, so that it can achieve the intake swirl with the best match of the diesel engine conditions [8].In this paper, a CFD numerical simulation was used to research into the intake flow of a diesel engine.
The intake flow characteristics of the two plans are numerical simulated and compared by using the 3-dimension CFD software.
The interaction between the two effects can be analyzed through the results of the numerical simulation.
