Injection valves for liquid-fuel mixtures and associated processes

The production of harmful substances during the operation of multi-cylinder diesel engines is reduced by separating the cylinders of the engine into two groups in combination with an exhaust gas return from one group to the other. The first group includes a plurality of the cylinders (2 to 6). The second group includes at least one cylinder (7), which is separated from the first group as far as combustion is concerned. A first fresh air suction intake (9) supplies fresh air to the group of first cylinders (2 to 6). An exhaust gas return device (24) feeds either directly or indirectly exhaust gas from the at least one second cylinder (7) through the first fresh air suction intake (9) to the group of first cylinders (2 to 6). A second fresh air suction intake (10) supplies fresh air to the second group of cylinders (7). The second fresh air suction intake (10) may also receive some exhaust gas which is then combusted by an additional fuel supply in the second fresh air suction intake (10).
