Abstract
Lately, numerical approach plays an important role in developing reciprocating engines due to the requirement of both higher performance and environmental protection, such as exhaust emission. Using numerical approach, the performance of each engine parts can be predicted before testing and some behavior which are difficult to be visualized directly can be understood. Especially, the engines in this paper have their particular characteristics to be solved. Evaluation of In-Direct Injection system (IDI) is key issue to improve exhaust emissions. Their small dimensions also cause some difficulties to design and development. In this paper, some numerical approaches including Computer Fluid Dynamics were used to solve these tasks.
In the end, we could introduce the new small IDI diesel engines with high performance, low exhaust gas emissions and good NVH characteristics. Using numerical approaches, the process of development has been shortened without any negative effects on reliability or other engine performances.
