Oscillating oil and gas separation device and engine

Abstract

This invention relates to the field of oil-gas separation technology, specifically disclosing an oscillating oil-gas separation device and its engine. The oscillating oil-gas separation device includes a housing and an oil-gas separation assembly. The housing is fixedly connected to a turbocharger, utilizing the high-frequency vibration of the turbocharger as a vibration source and transmitting it to the housing. Oscillating oil-gas separation can be achieved without a separate motor drive. A labyrinthine separation channel is designed, utilizing inertial force and the high-frequency vibration of the housing to cause the oil-gas mixture to undergo violent turning and oscillation, thereby separating larger oil droplets from the less dense gas, completing the initial oil-gas separation. Subsequently, a filtration structure further filters the oil and gas separated in the separation channel, capturing the remaining smaller oil droplets, thus achieving high oil-gas separation efficiency.
