Oxidation catalyst fault diagnosis unit and oxidation catalyst fault diagnosis method and internal combustion engine exhaust purification apparatus

To provide an oxidation catalyst fault diagnosis unit and fault diagnosis method that can perform fault diagnosis of an oxidation catalyst with good precision in a desired time period and an internal combustion engine exhaust purification apparatus equipped with the oxidation catalyst fault diagnosis unit.
An oxidation catalyst fault diagnosis unit which, in an exhaust purification apparatus of an internal combustion engine that delivers a reducing agent capable of generating ammonia to an exhaust passage on the upstream side of a reduction catalyst and selectively reduces and purifies NOx in exhaust with the reduction catalyst, is for performing fault diagnosis of an oxidation catalyst placed on the downstream side of the reduction catalyst, the oxidation catalyst fault diagnosis being equipped with a reducing agent dosage calculating portion that sets a dosage of the reducing agent such that a predetermined quantity of the ammonia flows out to the downstream side of the reduction catalyst, an oxidation efficiency calculating portion that obtains the efficiency with which the predetermined quantity of ammonia flowing out to the downstream side of the reduction catalyst is oxidized by the oxidation catalyst when the predetermined quantity of ammonia passes through the oxidation catalyst, and a fault determining portion that performs determination of whether or not the oxidation catalyst is faulty by comparing the oxidation efficiency with a predetermined reference value.

Rotary bullet feeder and toolhead assemblies for use with progressive cartridge reloading machines

Rotary bullet feeder and toolhead assemblies for use with commercially available progressive cartridge reloading machines automatically supply correctly-oriented bullets to a bullet seating die position thereof. The rotary bullet feeder assembly randomly collects hoppered bullets in a desired orientation in a multiplicity of bullet pockets formed along the peripheral edge of a rotating bullet feed ring. An arcuate bullet wall prevents gravitational release of the bullets contained in the bullet pockets until each of the bullet pockets, in turn, reaches the apex point along its circular route of travel, at which point an opening in the bullet wall allows a bullet to fall into a bullet guide for gravitational descent to a toolhead assembly. The toolhead assembly includes a toolhead plate for receiving the rotary bullet feeder assembly and a flat circular bullet feedwheel mounted for rotation on the underside of the toolhead plate. The bullet feedwheel includes a plurality of bullet feed holes equidistantly arranged in a circle proximate the peripheral edge of the bullet feedwheel. An indexing mechanism, positioned beneath the bullet feedwheel, serves to incrementally rotate or index the bullet feedwheel in response to each user actuation of the handle of the cartridge reloading machine. Each incremental indexing rotation of the bullet feedwheel serves to sequentially advance each bullet feed hole containing a bullet received from the rotary bullet feeder assembly into alignment with a conventional seating die positioned in the toolhead plate.
