Abstract
A chemical scavenging component includes a porous body that has a radical-scavenging material. The radical-scavenging material has a composition of, by weight, greater than 50% of cerium oxide that is chemically active with regard to oxygen-containing radicals.
Claims15
A chemical scavenging component for a fuel system, the component comprising:
- at least one of a porous body having a homogenous composition of radical-scavenging monolithic cerium oxide or a screen having a radical-scavenging coating thereon, the radical-scavenging coating having, by weight, greater than 50% of cerium oxide, wherein the cerium oxide of the porous body or of the coating is chemically active with regard to oxygen-containing radicals.
A chemical scavenging component for a fuel system, the component comprising:
- a substrate;
- and
- a radical-scavenging coating fixed on the substrate, and the radical-scavenging coating has a composition of, by weight, greater than 50% of cerium oxide that is chemically active with regard to oxygen-containing radicals in hydrocarbon fuel.
A fuel system comprising:
- fuel tank;
- at least one fuel injector;
- at least one fuel tube that connects the fuel tank with the at least one fuel injector;
- and
- a screen fixed in the at least one fuel tube, the screen including a radical-scavenging coating, and the radical-scavenging coating has a composition of, by weight, greater than 50% of cerium oxide that is chemically active with regard to oxygen-containing radicals, wherein the at least one fuel tube includes a fueldraulic circuit, and the screen is fixed in the fueldraulic circuit.
