| Research Abstract |
A systematic experimental research were conducted to clarify the ignition and combustion characteristics of fuel under the ambient conditions equivalent to the in-cylinder conditions of marine diesel engine with heavy exhaust gas recirculation. It is confirmed that the simultaneous reduction of NOx, Soot and CO can be achieved under a low O2 concentration condition, i.e., lower than 10%. The O2 fraction is a dominant factor of NOx emission and the amount of O2 is a dominant factor for both of Soot and CO emissions.
