Exhaust-gas supply device of a turbine wheel of an exhaust-gas turbocharger

摘要

An exhaust-gas supply device (1) of a turbine wheel (2) of an exhaust-gas turbocharger (3), having a two-channel turbine housing (4) and an exhaust manifold (7) which can be connected to an internal combustion engine (8), which exhaust manifold (7) has a first manifold channel (9) which connects first cylinders (Z1, Z4) of the internal combustion engine (8) so as to form a first manifold exhaust-gas path length, and a second manifold channel (10) which connects second cylinders (Z2, Z3) so as to form a second manifold exhaust-gas path length, to generate virtually identical overall exhaust-gas path lengths of the two channels.

1. An exhaust-gas supply device (1) of a turbine wheel (2) of an exhaust-gas turbocharger (3), comprising:
a two-channel turbine housing (4) having a first channel (5) with a short spiral length for forming a first volume and a second channel (6) having a long spiral length for forming a second volume, and an exhaust manifold (7) connected to an internal combustion engine (8),
wherein the exhaust manifold (7) further includes:
a first manifold channel (9) which connects first cylinders (Z1, Z4) of the internal combustion engine (8) so as to form a longer manifold exhaust-gas path length having a first volume, anda second manifold channel (10) which connects second cylinders (Z2, Z3) so as to form a shorter second manifold exhaust-gas path length having a second volume,
wherein the first manifold channel (9) having the longer manifold exhaust-gas path length is connected to the turbine housing (4) first channel (5) having the short spiral length, and the second manifold channel (10) having the shorter manifold exhaust-gas path length is connected to the turbine housing (4) second channel (6) having the long spiral length whereby the first and second manifold channels (9, 10) in combination with the first and second channels (5, 6) of the turbine housing (4) generate virtually identical overall exhaust-gas path lengths of combined channels (9, 10, 5, 6) from the engine to the turbine wheel.
