ATMOSPHERE-CLEANING DEVICE FOR VEHICLES

摘要

An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.

主权项

1. An atmosphere-cleaning device for vehicles, comprising:
a vehicle component that is arranged at a location at which a flow path of atmospheric air is formed while a vehicle is travelling; an ozone purifying body that is carried by the vehicle component and that has an ozone purification function; remover injection means configured to inject onto the ozone purifying body a remover for removing a deterioration-causing substance that causes a deterioration in an ozone purification function; and a controller programmed to set an injection amount of the remover from the remover injection means using at least one of a rate of decline in an ozone purification rate based on an ozone purification rate in an initial state of the ozone purifying body, an atmospheric air velocity with respect to atmospheric air passing through the ozone purifying body, and a bed temperature of the ozone purifying body.
