PCT No. PCT/EP97/04865 Sec. 371 Date Mar. 3, 1999 Sec. 102(e) Date Mar. 3, 1999 PCT Filed Sep. 8, 1997 PCT Pub. No. WO98/10185 PCT Pub. Date Mar. 12, 1998The invention concerns a drive arrangement (1) for the combustion of fuel, with an internal combustion engine (2), an intake air compressor (4) and an exhaust gas turbine (5) which drives the latter. An intake-air distributor (7) is provided between the compressor (4) and the internal combustion engine (2) and an exhaust gas chamber (8) is disposed between the internal combustion engine (2) and the exhaust gas turbine (5). Further provided are a container (12) and a nozzle (18) which is connected thereto via a first water-conveying pressure line (13), the nozzle injecting water into the scavenging air in front of the compressor (4). The internal combustion engine takes the form of a diesel engine (2), and the first pressure line (13) and the nozzle (18) are connected to the intake line (9) in front of a compressor (4) such that the atomizing water is injected into the compressor (4). There is further provided between the distributor (7) and the pressure reservoir (12) a pressure connection for controlling the amount of water to be injected. The invention further concerns a method of reducing the amount of Nox in the exhaust gases in a drive arrangement with an internal combustion engine, wherein atomized water is injected into the scavenging air in front of the compressor (4), and the pressure of the water in the container is determined from the pressure of the supercharged scavenging air. |
