Abstract

The exhaust gas feedback system is designed, so that the temp. of the exhaust gas in the gas feedback line (14), is determined in the flow direction before the non-return valve (18) and is supplied to a control unit (15). So that for example, the exhaust feedback control valve (17) is regulatory close able, depending on a specific temperature limit of the exhaust gas.
