Catalytic exhaust gas recirculation cooler

A potassium glass coating 52 on the internal surfaces of the fluid passages 50 of an i.c. engine EGR cooler 40 comes into contact with the exhaust gas stream from the engine to enhance or catalyse soot oxidation thus preventing or lessening of exhaust gas cooler fouling and loss of heat transfer efficiency due to carbonaceous deposits. The potassium glass may be composed such that conversion of carbon monoxide to carbon dioxide, and of nitrogen oxide to nitrogen dioxide, is insignificant. The potassium glass may be potassium calcium silicate (K2CaSiO4, KCS, K-Ca-Silicate) which releases K+ ions in the presence of the exhaust gas stream. The potassium glass may be applied over a length D that is less than 50% of the length of the internal walls 54 of the cooler, nearer the inlet 42.
