Abstract
An embodiment includes an apparatus and method of distributing gases within a catalytic converter assembly. Gases flow through at least one inlet into a housing and out of the housing through at least one outlet. A substrate is disposed at least partially between at least one of the at least one inlet and at least one of the at least one outlet. The mass flow rate of the gases across at least one surface of a deflector are substantially equalized as the gases flow through at least one of the at least one inlet into the housing and out of the housing through at least one of the at least one outlet.
Claims25
A catalytic converter assembly, comprising:
- a substrate;
- a housing having at least one inlet port and at least one outlet port;
- the at least one inlet and the at least one outlet being in fluid communication such that gases flow through the at least one inlet into the housing and out of the housing through the at least one outlet;
- the housing being adapted to receive the substrate;
- the substrate at least partially disposed between at least one of the at least one inlet and at least one of the at least one outlet;
- at least one deflector;
- the at least one deflector having at least one surface;
- the at least one deflector being moveably connected to the housing at a location generally between at least one of the at least one inlet and the substrate;
- and
- the at least one deflector being configured to substantially equalize the mass flow rate of the gases across the at least one surface as the gases flow through the at least one inlet into the housing and out of the housing through the at least one outlet.
A method of distributing gases within a catalytic converter assembly, comprising the steps of:
- flowing gases through at least one inlet into a housing and out of the housing through at least one outlet;
- disposing a substrate at least partially between at least one of the at least one inlet and at least one of the at least one outlet;
- and
- substantially equalizing the mass flow rate of the gases across at least one surface of a deflector as the gases flow through at least one of the at least one inlet into the housing and out of the housing through at least one of the at least one outlet.
A catalytic converter assembly, comprising:
- a substrate;
- a housing having at least one inlet port and at least one outlet port;
- the at least one inlet and the at least one outlet being in fluid communication such that gases flow through the at least one inlet into the housing and out of the housing through the at least one outlet;
- the housing being adapted to receive the substrate;
- the substrate at least partially disposed between at least one of the at least one inlet and at least one of the at least one outlet;
- at least one deflector;
- the at least one deflector having at least one surface;
- at least one protrusion at least one of extending from, attached to and formed integral with at least one of the at least one surface;
- the at least one deflector being moveably connected to the housing at a location generally between the substrate and at least one of the at least one inlet such that the gases flow across the at least one surface as the gases flow through the at least one inlet into the housing and out of the housing through the at least one outlet.
A deflector for use in a catalytic converter assembly, comprising:
- a generally polyhedron portion having a leading surface and a trailing surface separating a top surface and a bottom surface;
- and
- at least one protrusion at least one of extending from, attached to and formed integral with at least one of the top surface and bottom surface.
