| Abstract:The principles and characteristics for condition monitoring and diagnosis of diesel engine in-cylinder processes are introduced based on indicator diagram, vibration and instantaneous angular speed. Application prospect of each method for warship main diesel engines is discussed. The principles for measuring indicator diagram by electronic indicator are described. An electronic indicator was used to measure and analyze the indicator diagram from a main diesel engine model 6PC2-5L, which achieved good effectiveness and could reflect the operation conditions of main engines very well. |
