AI Technical Summary

Benefits of technology

The solution significantly reduces engine backpressure and improves fuel economy by evenly distributing gas flow and minimizing backpressure, resulting in a 33-50% decrease in backpressure and a 4.5-12% improvement in fuel economy.

Problems solved by technology

The interposition of a catalytic converter into the exhaust system can impede gas flow, creating backpressure that can significantly reduce engine power and increase fuel consumption.

Embodiment Construction

[0056]Exemplary embodiments of the invention are shown in FIGS. 1A through 2A.

[0057]FIGS. 1A, 1B and 2A show a catalytic converter apparatus 100 according to the first exemplary embodiment of the invention.

[0058]This apparatus 100 is for use in an exhaust system of an internal combustion engine (not shown) and will be seen to include a housing 102, a gas inlet 104, a gas outlet 106 spaced apart from the inlet 104 and an oval substrate element 108 that substantially fills the housing 102 in a radial or lateral dimension relative to an axis of gas flow from the inlet 104 to the outlet 106. The substrate element 108 contains an oval flow redistribution element 110 made out of an insulative material that thermally and physically separates the substrate into a central zone and a tubular outer zone surrounding the central zone. Each of the central zone and the outer zone is an extruded ceramic honeycomb coated with catalytic material and, but for the shapes and orientation to one another,...

Abstract

An improved catalytic substrate for use with a can in an automotive exhaust system. The improvement includes an insulation material thermally separating the substrate into a central zone and an outer zone surrounding the central zone. The insulation material, central zone and outer zone collectively defining a modified substrate. The insulation material is adapted such that in an operating condition, the gas flow through the modified substrate is characterized by a static pressure that, on the upstream-facing surface of the modified substrate has a peak at a point generally central to the upstream-facing surface of the modified substrate; as the upstream-facing surface extends radially away from the point to the periphery, decreases, but for a surge after the upstream-facing surface extends beyond the insulation material.
