Simulation Analysis and Evaluation of Inner Airflow Characteristics on the 2.0L Di Engine

Abstract:

In order to assess the rationality of the combustion chamber structure of 2.0L diesel engine equipped with high pressure common rail system, evaluation methods of the interior flow dynamic characteristics was put forward .And numerical simulation was carried out on the effect of different combustion chamber structure matching different fuel injection system parameters on the transient distribution of velocity field, concentration field, temperature field. The results show that: the suggested evaluation method in the combustion chamber structure design is reasonable; and for certain injection system, reasonable design and optimized combustion chamber structure parameters are used to organize air flow characteristic effectively. These are important measures to realize energy conservation and emission reduction on diesel engines.
