Abstract: Způsob ochrany pohonů s palivovými články před korozí za použití chladicích systémů, které jsou založeny na mrazuvzdorných koncentrátech na bázi alkylenglykolů nebo jejich derivátů pro vodné roztoky chladiva s elektrickou vodivostí maximálně 50 .mi.S/cm, spočívá v tom, že k mrazuvzdornému koncentrátu se přidá ester kyseliny orthokřemičité obecného vzorce I, ve kterém jsou substituenty R.sup.1.n. až R.sup.4.n. stejné nebo různé a značí C.sub.1.n.- až C.sub.20.n.-alkyl, C.sub.2.n.- až C.sub.20.n.-alkenyl, C.sub.1.n.- až C.sub.20.n.-hydroxyalkyl, případně substituovaný C.sub.6.n.- až C.sub.12.n.-aryl a/nebo glykoletherové substituenty vzorce -(CH.sub.2.n.-CH.sub.2.n.-O).sub.n.n.-R.sup.5.n., přičemž R.sup.5.n. značí vodík nebo C.sub.1.n.- až C.sub.5.n.-alkyl a n značí číslo 1 až 5. Dalším předmětem řešení je použití mrazuvzdorných koncentrátů na bázi alkylenglykolů nebo jejich derivátů obsahujících shora uvedený ester kyseliny orthokřemičité v pohonech s palivovými články.

Abstract: The invention relates to a method and a device for cooling an internal combustion engine. An aqueous, non-ionic coolant composition is used in a cooling circuit (14) of the internal combustion engine (11). In order to also ensure long-lasting protection against corrosion for light metal components of the engine that come into contact with the coolant, e.g. components made of magnesium or magnesium alloys, the cooling circuit has at least one deionization device (28), for example, an ion exchanger, for the coolant.
