There is provided an exhaust purification device including a particulate filter configured to collect particulates contained in an exhaust gas, an oxidation catalyst disposed in a front stage of the particulate filter and configured to have a carrier partially or entirely made of a material which absorbs a microwave, a housing in which the particulate filter and the oxidation catalyst are arranged, and a microwave generator configured to generate a microwave to be irradiated onto the oxidation catalyst in a direction to which the exhaust gas flows.

A fuel treatment module treats fuel with infrared radiation from a plurality of infrared radiation emitting elements arranged in a structure configured to ensure sufficient exposure of the fuel to infrared radiation. Such structure includes a head cap and spacer having through bores providing a manifold through which fuel flows into multiple IR/shunt columns of infrared radiation emitting elements that are disposed within a canister. Then the fuel moves out of the multiple IR/shunt columns into the open area of the canister where the fuel then flows around the exterior of the columns, exposing the fuel to further infrared radiation treatment.

A particulate filter includes a particulate capturing body configured to capture particulates contained in exhaust gas, and a dielectric waveguide provided around the particulate capturing body. The effective relative permittivity of the dielectric waveguide is higher than the effective relative permittivity of the particulate capturing body.

An antenna including an antenna electrode that transmits or receives microwaves, and a covering layer that supports an oxidation catalyst, that is formed from an inorganic material, and that covers the antenna electrode.
