    Abstract: An extraction apparatus (10) adapted to capture exhaust gas emitted by an internal combustion engine and to dilute the exhaust gas by mixing with air and also cool the exhaust gas. The extraction apparatus (10) has a first flow path (31), second flow path (32), and third flow path (33). The first flow path (31) extends between inlet (35) and an outlet (37) for air flow from the inlet to the outlet. The second flow path (32) receives exhaust gas emitted from the engine and delivers it into the first flow path (31) for mixing with an air flow along the first flow path. The third flow path (33) delivers water for mixing with the air flow. The arrangement is such that there is confluence of air, exhaust gas and water to provide a fluid mixture for discharging through the outlet (37). The exhaust gas is cooled using the cooling effects of the air and also the cooling effects of water in heat exchange relation with the exhaust gas prior to mixing of the exhaust gas with the air. There is also cooling of the mixture of exhaust gas and air using the cooling effects of water in heat exchange relation with the mixture, and also cooling by injection of water into the air. The various flow paths are configured for the requisite heat exchange relation.

    Abstract: A method to control the temperature of the exhaust gases of a supercharged internal combustion engine (1), the method comprising: determining the minimum air/fuel ratio (λ min ) of the exhaust gases downstream of the exhaust manifold (5) as a function of the flow rate (m air_scav ) of air that is not involved in the combustion taking place inside the cylinders (3) and flows directly from the intake manifold (4) into the exhaust pipe (10); detecting an air/fuel ratio (λ meas ) of the exhaust gases downstream of the exhaust manifold (5) by means of a sensor (25); and controlling the supercharged internal combustion engine (1) as a function of the comparison between the air/fuel ratio (λ meas ) of the exhaust gases detected by the sensor (25) and/or the minimum air/fuel ratio (λ min ) of the exhaust gases with a number of threshold values (UTV OL_SCAV , UTV INHIB_SCAV , UTV LIMIT_SCAV, LTV OL_SCAV , LTV INHIB_SCAV , LTV LIMIT_SCAV , SV) .
