Abstract
Methods and systems are provided for a turbocharger comprising a compressor inlet shaped to mitigated condensate formation therein. In one example, system may include a condensate trap which runs along an inner wall of the compressor inlet and is shaped to trap condensate.
Claims20
A turbocharger for an internal combustion engine, comprising:
- a compressor shaped to compress intake air flowing to the internal combustion engine, the turbocharger further comprising an exhaust-gas turbine for driving the compressor, the compressor further comprising a compressor rotor in a compressor housing defining a compressor inlet upstream of the compressor rotor, the compressor inlet fluidically connected to at least one supply line of a EGR device, wherein the compressor inlet comprises a condensate trap which has at least one barrier, which runs along an inner wall of the compressor inlet, shaped to capture condensate, and wherein the at least one condensate trap is fluidly coupled directly to at least one condensate drain for discharging condensate, the at least one condensate drain extending from the inner wall to a reservoir.
A system, comprising:
- a compressor inlet comprising an upstream wall comprising a first condensate trap and a downstream wall comprising a second condensate trap, wherein the first condensate trap is obtusely angled and the second condensate trap is acutely angled relative to intake air flow, wherein the upstream wall and the downstream wall form portions of an inner compressor wall spaced away from a compressor housing.
A method, comprising:
- flowing a mixture of exhaust gas and intake air to a compressor;
- and
- capturing condensate accumulating on surfaces of a compressor inlet of the compressor via a first condensate trap and a second condensate trap, wherein the first condensate trap is more angled than the second condensate trap relative to a general flow direction of the mixture, wherein the first condensate trap is arranged on an upstream inner wall and the second condensate trap is arranged on a downstream inner wall.
