Abstract (en)
[origin: EP4039956A1] The present invention is configured to comprises: fuel injection valves (43A-43D) that inject a fuel (F) in a combustion chamber (75) of an internal combustion engine (10); and cooling medium supply devices (63A-63D) that supply, into the combustion chamber (75), a liquid (68) having ignitibility that is inferior to the fuel (F), wherein before the fuel injection valves (43A-43D) perform main injection (JM1) of the fuel (F), the cooling medium supply devices (63A-63D) supply the liquid (68) to a predetermined region (FL) around a plurality of fuel injection ports (49) of the fuel injection valves, thereby lowering the temperature of the predetermined region (FL).
