| Abstract:Aiming at the uncertainty in the measurement of diesel engine power, according to the method in JJF1059-2012 "Evaluation and Expression of Uncertainty in Measurement", the uncertainty of engine power under the nominal working condition was evaluated, and the component which has bigger influence on the uncertainty and its reasons were sorted out. Finally, suggestions about the selection of dynamometer for the power measurement of marine diesel engines were put forward. |
| Key words: marine diesel engine power uncertainty in measurement dynamometer |
