  • In order to improve the computation precision of exhaust gas flows, a new calculation method of brake NOx emission from marine diesel engine was deduced by chemical reaction equations based on incomplete combustion and the principle of element quality balance, CO2 gas was ignored, iterative calculation was avoided.For meeting the requirements and characteristics of on-board measurement of NOx emission, approximate calculation methods based on the new method and simplified measurement were discussed. The calculation result of a example shows that the exhaust gas flows calculated by the new method are more accurate by 1.1%~1.5% than by carbon balance method, brake NOx emission is more accurate by 0.3%~0.6%, and the error of weighted brake NOx emission caused from ignoring CO and HC is less than 0.2%. The result proves the feasibility of simplified on-board measurement of NOx emission because of ignoring CO and HC by handy gas analyzer.
