A
Abstract:
PCT No. PCT/DK93/00398 Sec. 371 Date Dec. 4, 1995 Sec. 102(e) Date Dec. 4, 1995 PCT Filed Dec. 2, 1993 PCT Pub. No. WO94/29587 PCT Pub. Date Dec. 22, 1994Exhaust gas in a supercharged internal combustion engine is recycled from the high pressure side of the turbocharger to the charging air system of the engine. At least part of the recycled exhaust gas is humidified to largely 100 percent relative humidity. This on one hand cools the gas to that the temperature at initiation of the combustion in the engine cylinders is lowered, and on the other hand the heat capacity of the steam in the gas restricts the temperature raise occurring during the combustion. These factors both act to reduce the amount of NOx produced by the combustion. The addition of water is effected by a scrubber (16) which purifies the recycled gas. A blower (17) augments the pressure of the recycled gas. The scrubber may be made to generate fresh water by designing it with several stages where sea water is supplied to the first stage and fresh water to the last stage.
