An arrangement (10) for mixing a first and a second gas flow, for example, an inlet flow (A) with an exhaust gas (B) return flow in a diesel engine (22). An air conduit (20) has an inlet for the first flow and an inlet for the second flow, in order to achieve the mixing. A valve body (52) is arranged to be displaced in the longitudinal direction of the air conduit (20) at the inlet for the second flow in order to achieve a variable venturi effect and in this way a variable suction effect and mixture of the mixed flow. One or more fuel injectors (80) inject fuel into the air conduit (20) to pre-mix fuel with the first and second gas flows before reaching the engine cylinders (26) for combustion. |
