Abstract

An automotive exhaust pipe manifold has a pipe emerging from each cylinder and merging in the direction of gas flow into the wide end of a single truncated conical box (2). The incoming exhaust pipes form a regular arrangement within the box. The conical space between the incoming pipes and the end of the truncated cone box is occupied by a smaller secondary cone (3) with concave sides.

Description

Die Erfindung betrifft Einrichtungen und Verfahren entsprechend dem Oberbegriff des Anspruch 1.The invention relates to devices and methods according to the Preamble of claim 1.

Das Fächerrohr ermöglicht den entweichenden Abgasen aus mehrzylindrigen Verbrennungsmotoren gleichmäßig und schnell, in der Reihenfolge des Zündvorganges, aus dem Zylinderkopf abzuströmen.The fan tube enables the escaping exhaust gases from multi-cylinder Internal combustion engines smoothly and quickly, in the order of Ignition process to flow out of the cylinder head.

Jeder Zylinderkopf-Ausgang hat ein eigenes Abgangsrohr, daß direkt am Zylinderkopf angeschlossen wird. Diese einzelnen Abgangsrohre werden nach leistungs- und strömungstechnisch korrekt abgestimmten Rohrlängen in ein Rohr zusammengeführt.Each cylinder head outlet has its own outlet pipe that directly on Cylinder head is connected. These individual outlet pipes are after Pipe lengths correctly matched in terms of performance and flow technology in one pipe merged.

Hochleistungs-Fächerrohrkrümmer mit Laminarströmungs-Leiteinsatz inseitig, in Form einer Konkavpyramide in der Rohrzusammenführung von mehreren Rohren in ein Rohr bewirkt, daß keine zusätzlichen Geräusche auftreten können und daher nicht extra gedämpft werden müssen.High-performance manifold elbow with laminar flow guide insert on the inside, in the form of a concave pyramid in the pipe junction of several Pipe into a pipe means that no additional noise can occur and therefore do not need to be steamed extra.

Device according to claim 1, characterized in that the fan tube from the escaping exhaust gas multi-cylinder internal combustion engines a smooth, faster removal with minimal flow losses. 3. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die einzelnen Abgangsrohre, bestehend aus mehrere der jeweiligen Zylinderzahl des Motors entsprechenden Anzahl von Einzelrohren, leistungstechnisch abgestimmten Rohrlängen entsprechen.3. Device according to claim 1, characterized in that the individual outlet pipes consisting of several of the number of cylinders corresponding to the engine Individual pipes correspond to pipe lengths matched in terms of performance. 4. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Hochleistungs-Fächerrohrkrümmer mit Laminarströmungs-Leiteinsatz (Fig. 2 Punkt 3) inseitig, in Form der Konkavpyramide, mögliche Eigengeräusche gesichert vermeidet.4. The device according to claim 1, characterized in that the high-performance fan pipe elbow with laminar flow guide insert ( Fig. 2 point 3 ) on the inside, in the form of the concave pyramid, avoids possible intrinsic noise.
