Taking the air intake pipe in the engine as the target of the research, the software STAR-CDE is adopted to build a three-dimensional simulation model for the air intake pipe in the engine T12V190 with the aim to solve the problems of air input deficiency, Combustion deterioration and performance reduction of one cylinder caused by the non-uniformity. Moreover, the non-uniformity of the flux of air intake of the air intake pipe is mainly studied and analyzed through a calculation on the CFD of the inner flow field of the three dimension of the air intake pipe in the engine T12V190. In addition, a retrofit design with multiple schemes is made based on the cavity structure of the original mold for the air intake pipe. Finally, through a comparison among the three selected designs, a more feasible retrofit designing scheme and a designing thought on the air intake pipe in the engine with directional significance are got.

Filling And Solidification

In order to improve the utilization of K424 alloy, Z-Cast analysis software is used to get three-dimensional flow field and temperature coupling simulation in the process of K424 alloy castings filling, by considering the effection of pouring temperature, casting speed, shell thermal conductivity and temperature on the morphology of filling.A three-dimensional simulation of temperature changes in solidification process of molten metal was performed based on the filling simulation. The simulation results on flow field and temperature field shows the order of filling and solidification in different parts of the casting ,and determines the position where cold shut and misrun appears, which provides theoretical support to the improvement of technology plan.
