Patent ID: 8771600

Claim:
An air pollution control apparatus for hydrocarbon combustion engines comprising: a precipitation chamber with an electrical ground connection; an inlet port connected to the precipitation chamber; an outlet port connected to the precipitation chamber; a first and a second plate assembly, each plate assembly comprised of at least two planar collecting plate electrodes within and electrically connected to the precipitation chamber, where the collecting plate electrodes have at least one opening within the plane of the collecting plate electrode; a rod passing through the openings of the collecting plate electrodes; an ionizing plate mounted on the rod, where the ionizing plate has sharp discharge points along a periphery of the ionizing plate, and where the ionizing plate is mounted at a predetermined distance K away from a nearest collecting plate electrode; a first end plate attached to a first end of the rod, a second end plate attached to a second end of the rod; and an insulator securely mounting each end plate to the precipitation chamber; a first transformer electrically connected to the first or second end plate of the first plate assembly, the first transformer capable of inducing a first voltage differential between the ionizing plate attached to said rod and the collecting plate electrodes; and a second transformer electrically connected to the first or second end plate of the second plate assembly, the second transformer capable of inducing a second voltage differential between the ionizing plate attached to said rod and the collecting plate electrodes.
