The 3D-CFD investigations at the 3-cylinder virtual engine test bench were conducted to validate on the full multi-cylinder engine the optimized water injection strategies studied at the single-cylinder engine. In particular, two different high-load operating points are considered, as listed in Table 7.1. The first operating point, OP 5 in the table, is a knock-limited operating point at 2500 rpm and 22 bar IMEP at stoichiometric conditions, and the second operating point, OP 6, is a full load point at high engine speed at 5500 rpm and 20 bar IMEP also operated at stoichiometric conditions.
