PCT No. PCT/DK93/00399 Sec. 371 Date Dec. 4, 1995 Sec. 102(e) Date Dec. 4, 1995 PCT Filed Dec. 2, 1993 PCT Pub. No. WO94/29579 PCT Pub. Date Dec. 22, 1994A supercharged internal combustion engine (1), such as a main engine of a ship, has a compressor (9) delivering charging and scavenging air to the engine cylinders, and a cooler (12) for cooling the air from the compressor. The cooler (12) is designed to establish direct contact between the scavenging and charging air and the cooling water, preferably by pressure atomization of the water in the air. The cooler (12) has a number of consecutive atomizer sections, and a drop collecting section (33) separating drops of water from the air may be provided between at least two atomizer sections. A delivery pump (49) supplies fresh water to atomizer sections in the cooler, and at least one of the drop collecting sections of the cooler delivers fresh water to a storage tank (50), which tank is pressured to substantially the same pressure as the air pressure in the cooler. The air may be cooled in plural stages (13-16), and sea water may be used for cooling and humidification of the air in the first stage. When the humidity-saturated air is cooled with atomized fresh water in subsequent stages (14-16), the cooler produces a surplus of fresh water. |
