| Measurement and simulation of pollutant emissions from marine diesel combustion engine and their reduction by exhaust gas recirculation
Nader Larbi
The Journal of Mechanical Science and Technology, vol. 22, no. 11, pp.2263-2273, 2008
Abstract : Taking into account the complexity and cost of a direct experimental approach, the recourse to simulation, which can
also predict inaccessible information by measurement, offers an effective and fast alternative to apprehend the problem
of pollutant emissions from internal combustion engines. An analytical model based on detailed chemical kinetics employed
to calculate the pollutant emissions of a marine Diesel engine in general gave satisfactory results compared to
experimentally measured results. Especially, the nitric oxide (NO) emission values were found to be higher than the
limiting values tolerated by the International Maritime Organization (IMO). Thus, this study was undertaken to reduce
to the maximum these emissions. The reduction of pollutant emissions is apprehended with exhaust gas recirculation
(EGR).
