Generating a computational grid when modeling the intake system of a tractor diesel engine to reduce the impact on the environment

Abstract

Abstract The processes in the intake system of agricultural tractor diesel internal combustion engines (TDICE) have a spatial and non-stationary character, accompanied by heat exchange and energy dissipation. The complex configuration of the exhaust system elements, which is also determined by the existing dimensional restrictions, leads to the fact that it is not possible to talk about any orderly flow in these areas. Due to such a complex nature, a detailed study of the flow parameters even for one modification of the exhaust system on a working TDICE is associated with significant time and money. If we take into account that in order to reduce the environmental impact, it is necessary to find a more optimal form, and for this it is necessary to test several different configurations of intake systems, then it becomes clear that researchers want to simplify the task in some way in order to obtain a positive effect by spending less money and time. And here it becomes indispensable to use physical models that more or less correspond to the parameters of the intake systems of the prototype TDICE.
