Catalyst system for lean burn engines
InactiveUS20040082470A1Minimizes oxygen storage functionMinimize releaseInternal combustion piston enginesDispersed particle separationFree zoneAlkaline earth metal
A catalyst system to provide emission reductions under lean and stoichiometric conditions. The catalyst system comprises a forward catalyst having a first cerium-free zone including oxides of aluminum, alkali metals and alkaline earth metals and precious metals and a second zone with a lower loading of precious metals, oxides of aluminum, alkali metals or alkaline earth metals. This forward catalyst stores NOx emissions under lean conditions for subsequent reduction and converts HC, CO and NOx during stoichiometric operation. The second downstream catalyst includes precious metals, reduces emissions under stoichiometric conditions, and stores any residual NOx emitted from the first catalyst for subsequent reduction. In another embodiment, a forward catalyst has top and bottom layers designed to reduce emissions under lean conditions. In this embodiment, a second downstream catalyst is used to reduce emissions under stoichiometric conditions. In yet another catalyst, multiple zones are created within a single catalyst.

Compactor wheel with trash exclusion properties
Landfill compactor vehicles having wheels equipped with wedge shaped cleats tend to accumulate about the vehicle's axle trash such as cable, wire, rope and the like debris requiring daily removal to permit unobstructed axle rotation. The wheel construction of this invention provides compaction cleats of two types, contour and traction, in rows positioned across the width of the wheel with substantially no cleat free zone adjacent the wheel edges but with a row of contour teeth arranged adjacent the wheel's inner edge thus affording trash exclusion properties to the compactor wheel.
