The current chapter reports an extract of the paper [21] and particularly the influence of water injection timing on the soot production, both considering experiments and 3D-CFD simulations. The emission investigations have been led at OP2, the only considered load point that did not present constraints neither in terms of Knock onset nor considering exhaust gas temperature before turbine. For such reasons the water injection potentials are investigate on OP2 not with the purpose of increasing the engine efficiency, but for evaluate the effects in terms of emission reduction.
