| Abstract: | In this paper, the fault on main engine is taken as an example on trial trip of 46 000 t ship. Formation and reason on the abnormal indicator diagram are introduced in detail for the cylinder of main engine in its every burning stage. Through analysis to the burning workstate on the indicator diagram, you can judge the state of burning normal or not. |
