Abstract
A lubricant deterioration detection device of the present invention includes a gas sensor that selectively detects a carbonyl compound. The gas sensor is configured to detect the carbonyl compound from at least one of formaldehyde, acetaldehyde, propanal, butanal, pentanal, n-hexanal, n-heptanal, formic acid, and acetic acid. The detection deterioration device further includes an oil removal portion that removes an oil mist generated from the lubricant.
