Estimating the term…
A 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.
A supercharged internal combustion engine comprising;
A supercharged internal combustion engine comprising;
A method of operating a cooler for cooling intake air of a supercharged internal combustion engine having combustion chambers, after the air has left a compressor and before the air is delivered to the combustion chambers, comprising the steps of cooling said intake air in a number of stages only by means of pressure atomization of cooling water, atomizing cooling water in the air in the first stage of the cooler, subsequently removing drops of water from the air, and atomizing fresh water in the air in at least one subsequent stage.
