Abstract
Abstract A manifold reactor of a dual-walled structure including inner and outer cores, the inner core defining a reactor chamber therein, wherein the space defined between the inner and outer cores is opened to the reactor chamber so as to be filled with exhaust gases which, after having filled the heat insulating space, is drawn therefrom as EGR gas.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
A manifold reactor comprising an inner core which defines a reactor chamber therein, said inner core having inlet and outlet ports for conducting exhaust gases into and out of said reactor chamber, and an outer core which encloses said inner core while defining a heat insulating space between said inner core while defining a heat insulating space between said inner and outer cores, said heat insulating space being connected with said reactor chamber through an opening formed in said inner core and communicating to an EGR gas intake port formed in said outer core.
Claim 2
Dependent Claim
94 words
A manifold reactor comprising an inner core which defines a reactor chamber therein, said inner core having inlet and outlet ports for conducting exhaust gases into and out of said reactor chamber, and an outer core which encloses said inner core while defining a heat insulating space between said inner core while defining a heat insulating space between said inner and outer cores, said heat insulating space being connected with said reactor chamber through an opening formed in said inner core and communicating to an EGR gas intake port formed in said outer core.
Claim 3
Dependent Claim
15 words
The manifold reactor of claim 1, wherein said opening is located adjacent said outlet port.
Claim 4
Dependent Claim
21 words
The manifold reactor of claim 1, wherein said EGR gas intake port is located as far from said opening as possible.
Claim 5
Dependent Claim
39 words
The manifold reactor of claim 1, wherein said reactor chamber is divided into a plurality of chamber portions through which exhaust gases successively flow so that the gases stay for a sufficient time to finish high temperature oxidization therein.
