Problems solved by technology

[0006] If the exhaust main line is to be closed for the entire exhaust volume flow, and the exhaust gas flow is to be deflected by a separate element upstream of the closure and reintroduced by another element downstream of said closure, several components must be adopted and coordinated in the system. known valves, resulting in the corresponding space and effort required to actuate and select

Abstract

The invention relates to a four-way exhaust gas valve, which has a permanent inlet, a permanent outlet, a selectable inlet, a selectable outlet and a pivotable valve flap. The pivotable valve flap is arranged for switching between a first mode of operation, in which exhaust gas entering through the permanent inlet is guided directly to the permanent outlet, and a second mode of operation, in which exhaust gas entering through the permanent inlet is discharged through the selectable outlet and exhaust gas re-entering through the selectable inlet is discharged through the permanent outlet, whereby one of the inlets or outlets is not coplanar with the remaining others. The four-way exhaust gas valve is used to heat the exhaust gases of an internal combustion engine when directed through a latent heat reservoir at cold starting or low load operation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from patent application No. 102012107839.4 filed in Germany on August 24, 2012, the entire content of which is incorporated herein by reference. technical field [0003] The present application relates to a four-way exhaust valve, in particular for selectively coupling / incorporating a latent heat store into or disconnecting it from the exhaust gas flow under certain specific operating conditions of an internal combustion engine. This exhaust valve is sometimes called a four-way butterfly valve. Background technique [0004] Exhaust gas aftertreatment systems of internal combustion engines are generally designed as passive systems, through which the exhaust gas passes completely in all operating situations. The exhaust gas experiences some resistance when flowing through the system, which reduces the overall efficiency of the system. In order to reduce emissions and exhaust noise under...
