Embodiment Construction

[0011] The internal combustion engine 10 schematically represented in FIG. 1 includes an engine block 11 having six piston cylinders 12 with an intake manifold 13 and an exhaust manifold 14 . The exhaust gas is led to the turbine rotor 17 of the turbocharger unit 16 via the exhaust pipe 15 . The turboshaft 18 drives the compressor wheel 19 of the turbocharger unit, which compresses the intake air via the intake line 20 and delivers the intake air via the intercooler 21 to the intake manifold 13 . Fuel is supplied to each cylinder 12 through injectors (not shown).

[0012] The exhaust gas that has passed through the turbocharger unit 16 is led to the atmosphere via an exhaust line 22 . The exhaust gas is also returned to the intake side of the engine via line 24 as so-called EGR gas for reducing engine nitrogen oxide emissions according to the prior art. This line includes valve 25 which acts as a regulating valve to regulate EGR flow. Additionally, there is a cooler 26 for ...

Abstract

The invention relates to an EGR mixer arrangement (27) for mixing the gas into the intake air of a turbocharged internal combustion engine (10) . The arrangement comprises an inlet port (28) with connection for a branch pipe (30) , which with an insertion section (31) opens out into the inlet port. The insertion section (31) forms a diffuser vane with a surface which is positively double-bent in the direction of flow of the intake air and which extends in a curved shape in the flow direction (29) of the inlet port (28) .

Description

technical field [0001] The present invention relates to an EGR (Exhaust Gas Recirculation) mixer device for mixing gas into the intake air of a turbocharged internal combustion engine, the device comprising an inlet connected to a branch pipe which opens outwardly into the inlet with an insertion portion. Background technique [0002] Recirculation of exhaust gas, so-called exhaust gas recirculation (EGR) is a commonly known method and device for influencing combustion within an internal combustion engine, wherein a portion of the total exhaust gas flowing from the engine is returned to the intake side of the engine in a secondary flow , where this portion is mixed with intake air for delivery into the engine cylinders. When combustion occurs with reduced oxygen content due to the mixture of EGR, the temperature of combustion is reduced. This makes it possible to reduce the amount of nitrogen oxides (NOx) in the exhaust gas emissions into the surrounding environment. [00...
