摘要
Taking into account the complexity and cost involved to conduct an experimental investment, the recourse to a tool of simulation, which in turn entails access to information by measurement, offers an effective and fast alternative to deal with 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 gave results, in general, satisfactory compared to experimentally measured results. Especially the NO emission contents are found higher than the standards limiting values set out by the International Maritime Organisation (IMO). Thus, this study is undertaken in order to reduce as much as possible these emissions. The reduction of pollutant emissions is apprehended with water injection. (C) 2010 Elsevier Ltd.
