Abstract

See full text

This disclosure describes an exhaust assembly that includes an exhaust tube and a coolant passage. The exhaust tube is oriented about an axis and an exhaust gas is configured to flow through the exhaust tube in a direction away from an end of the exhaust tube. The coolant passage is oriented about the axis radially outward of the exhaust tube, the coolant passage having an inner shell and an outer shell. The exhaust assembly further includes an expansion reservoir positioned vertically (relative to a gravitational reference) above the coolant passage. The expansion reservoir and coolant passage are fluidly coupled by a conduit having a first diameter. The expansion reservoir is coupled with a coolant reservoir by a second conduit having a diameter less than the first diameter. Vapor after a hot shutdown travels up the first conduit and is replaced by coolant flowing down the first conduit.
