A device is specified for increasing the temperature of the exhaust gas from a diesel engine, which is intended to support the combustion of the carbon particles contained in the exhaust gas in an exhaust system close to the engine. An exhaust gas-air mixture is fed to the intake connections of the diesel engine via a constant-flow two-way valve. The exhaust gas is diverted from an exhaust pipe via a recirculation pipe. The two-way valve may be controlled as a function of the number of revolutions and/or temperature. Particularly in the starting phase, when idling and coasting, the proportion of exhaust gas is increased with corresponding reduction of the proportion of air so that the temperature of the gas mixture is relatively high due to the proportion of exhaust gas. A contrary adjustment occurs in full- load operation. <IMAGE> |
