    제목(영문) Numerical Analysis on the Oil Film Behavior of Engine Main Bearing Considering Dilution of Diesel Fuel
    저자 김한구 (Han Goo Kim ,다불산업(주) 기술연구소 ) ▷공저자 네트워크 보기
    초록 This paper describes the influence on engine main bearing behavior of the oil film when the fuel is
    diluted on a diesel engine equipped with DPF system. Oil film pressure and the thickness is calculated in accordance
    to the fuel dilution. The calculation is based on the nwnerical analysis of the engine main bearing. As a
    result, the engine oil viscosity decreased as the fuel dilution increased. This led the increment of the maximum
    oil thickness pressure. Verification of the minimum oil film thickness settlement by the engine gas pressure and
    the fuel dilution was confirmed. Destruction possibility of the engine main bearing was foreseen when the engine
    speed was 2000 rpm with the fuel dilution 15% and the 5W40 engine oil.
