2영역모델을 이용한 직접분사식 디젤엔진의 NO생성예측 = Prediction of the Nitric Oxide Formation using a Two-Zone Model in a Diesel Engine

다국어 초록 (Multilingual Abstract)

In this study, numerical calculation is carried out to investigate the influence of injection timing and fuel amount on Nitric Oxide(NO) formation using a two-zone model in a diesel engine. Results can be summarized as follows.<br/>
The NO formation is very sensitive to burned gas temperature, so multi-zone model must be applied to combustion process to predict burned gas temperature exactly. Since burned gas temperature increase rapidly during the premixed combustion. Most NO is formed within 20 degree crank angle after ignition. As the injection timing is retarded, the combustion occurs later in the expansion process which causes the decrease of burned gas temperature and, as a result. NO formation decrease. The increase of fuel amount results in the increase of earlier formation of NO in the engine<br/>
