Analysis on the Inhomogeneity of Air Intake and Retrofit Optimization of the Air Intake Pipe in the Engine T12V190

Abstract:

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.
