Exhaust manifold for a vehicle

Abstract

An exhaust manifold for a vehicle includes a plurality of runners respectively connected to a plurality of exhaust ports of an engine; a first exhaust passage communicating with at least one of the plurality of runners; and a second exhaust passage communicating with a remnant of the plurality of runners, wherein the first and second exhaust passages, and the plurality of runners are formed inside a monolithic manifold body.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority of Korean Application No. 10-2004-0052433, filed on Jul. 6, 2004, the disclosure of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to an exhaust system of a vehicle. More particularly, the present invention relates to an exhaust manifold for a vehicle. BACKGROUND OF THE INVENTION [0003] Generally, as shown in FIG. 1, an exhaust system of a vehicle is for exhausting a gas from cylinders, and includes an exhaust manifold 1 and a muffler 2. [0004] Such a conventional exhaust manifold 1 includes a first exhaust pipe 11, a second exhaust pipe 12, a third exhaust pipe typically 13 and a fourth exhaust pipe 14 that are respectively connected to a plurality of exhaust ports (not shown). [0005] In addition, the exhaust manifold 1 further includes first and second connecting pipes 21 and 22. The first pipe 11 and the third pipe 13 meet at the first connecting...

AI Technical Summary

Benefits of technology

[0012] Embodiments of the present invention provide an exhaust manifold for a vehicle having non-limiting advantages employed to all vehicles, regardless of whether an engine compartment thereof is small or not.

Problems solved by technology

However, in an aspect of a layout, the conventional exhaust manifold has a problem of requiring excessive mounting space.

The first, second, third, and fourth exhaust pipes, the first and second connecting pipes, and the collecting duct consume excessive volume of an engine compartment, and therefore, such a conventional exhaust manifold is not appropriate for a vehicle that has a small engine compartment.
