Abstract: Se describen un procedimiento y un aparato para refrigerar un motor de combustion interna. En una circulacion de refrigeracion del motor de combustion interna, se utiliza una composicion refrigerante no ionica acuosa. Con la finalidad de asegurar una proteccion duradera contra la corrosion incluso para los componentes de metal ligero del motor, por ejemplo componentes que comprenden magnesio o aleaciones de magnesio, las cuales estan en contacto con el liquido refrigerante, teniendo la circulacion refrigerante por lo menos un medio de desionizacion, por ejemplo un intercambiador de iones, para el liquido refrigerante.

Abstract: Ready-to-use aqueous coolant compositions having alkylene glycols, glycerol and/or 1,3-propanediol and a) from 0.05 to 10% by weight, based on the total amount of the composition, of one or more polyethylene glycols and/or polypropylene glycols and b) from 0.01 to 10% by weight, based on the total amount of the composition, of one more carboxamides and/or sulfonamides are useful for inhibiting corrosion in the case of magnesium and magnesium alloys.
