Abstract:
1. A system for a vehicle, the vehicle comprising: a first ozone sensor that generates a first sensor signal indicating a first amount of ozone in air flowing into a radiator; a second ozone sensor that generates a second sensor signal indicating a second amount of ozone in air flowing out of the radiator; and a grounded metal housing located outside of an engine compartment of the vehicle, wherein the grounded metal housing encases the first ozone sensor and the second ozone sensor, and wherein the first ozone sensor is partitioned from the second ozone sensor within the grounded metal housing; a first conduit having an inlet located upstream from the radiator, wherein the first conduit provides air from the inlet located upstream from the radiator to the first ozone sensor through a first opening in the grounded metal housing; a second conduit having an inlet located downstream from the radiator, wherein the second conduit provides air from the inlet located downstream from the radiator to the second ozone sensor through a second opening in the grounded metal housing; and a control module that receives the first sensor signal and the second sensor signal and that determines an ozone conversion rate based on the first sensor signal and the second sensor signal.
