ABSTRACT:
A collector for liquid cooled exhaust includes a retention member, a coolant transfer plate and a collector housing. The retention member fits between at least two exhaust jacket pipes and is attached thereto. Holes are formed through the coolant transfer plate to receive the at least two exhaust jacket pipes and exhaust pipes. Such holes form respective sealing grooves therein, and respective sealing rings are received in such sealing grooves. The coolant transfer plate is secured to the retention member with welding or the like. At least one coolant opening is formed through each exhaust jacket pipe at substantially at end thereof, adjacent a coolant passage cavity in the coolant transfer plate. The collector housing is attached to the coolant transfer plate. Coolant flows between the exhaust pipes and exhaust jacket pipes; through the coolant transfer plate; and through the coolant housing.
