Abstract Based on the principles of heat transfer, an oil film model in the engine cylinder was established. Under the condition of cold state, the influence of factors such as engine fuel injection, fuel drop point, cylinder inner wall temperature, and inlet fluid on the oil film is comprehensively considered to establish an oil film quality prediction model. Based on the measurement of the compensation oil quantity in the transition conditions, the variation of the oil film during the transition is analyzed. The experimental results show that the velocity of the airflow in the intake port and the temperature and pressure… More >
