In one configuration, the present disclosure provides a cylinder including a first housing, a second housing, and an insert. The first housing includes a first body portion and a first collar portion. The first body portion has a first inner diameter, and the first collar portion has a second inner diameter that is greater than the first inner diameter. The second housing includes a second body portion and a second collar portion. The second body portion has a third inner diameter and the second collar portion has a fourth inner diameter that is greater than the third inner diameter. The second housing is coupled to the first housing such that the first and second collared portions cooperate to form an annular channel. The insert is disposed within the annular channel formed by the first and second collared portions.

1. A cylinder, comprising: a first housing including a first body portion and a first collar portion, the first body portion having a first inner surface defining first inner diameter, the first collar portion having a second inner surface defining a second inner diameter that is greater than the first inner diameter;a second housing including a second body portion and a second collar portion, the second body portion having a third inner surface defining a third inner diameter, the second collar portion having a fourth inner surface defining a fourth inner diameter that is greater than the third inner diameter, wherein the second housing is coupled to the first housing such that the second and fourth inner surfaces of the first and second collar portions cooperate with one another to at least partially form an annular channel; andan insert disposed within the annular channel formed by the second and fourth inner surfaces of the first and second collar portions. 2. The cylinder of claim 1, wherein first and second housings are formed from a first material having a first heat transfer coefficient and the insert is formed from a second material having a second heat transfer coefficient that is less than the first heat transfer coefficient. 3. The cylinder of claim 1, wherein the insert is constructed from a ceramic. 4. The cylinder of claim 3, wherein the ceramic is zirconia. 5. The cylinder of claim 1, wherein the first housing and the second housing overlap one another at a junction of the first collar portion and the second collar portion. 6. The cylinder of claim 5, wherein the insert overlaps the junction. 7. The cylinder of claim 5, wherein the first housing is attached to the second housing at the junction. 8. The cylinder of claim 7, wherein the first collar portion includes a first series of threads and the second collar portion includes a second series of threads, the first series of threads engaging the second series of threads to attach the first housing to the second housing. 9. The cylinder of claim 1, wherein the first housing includes a first threaded portion and the second housing includes a second threaded portion, the first threaded portion being threadably coupled to the second threaded portion to attach the first housing to the second housing. 10. The cylinder of claim 9, wherein the first threaded portion is a threaded inner surface of the first housing and the second threaded portion is a threaded outer surface of the second housing. 11. The cylinder of claim 9, wherein the insert is concentrically disposed within the first threaded portion and the second threaded portion. 12. The cylinder of claim 1, wherein the first body portion defines a first plurality of ports arranged circumferentially about the first body portion, and the second body portion defines a second plurality of ports arranged circumferentially about the second body portion. 13. The cylinder of claim 1, wherein the first body portion of the first housing has a first end defining a first axial end surface, the second body portion of the second housing has a second end defining a second axial end surface opposing the first axial end surface of the first housing, and the first and second axial end surfaces of the first and second housings cooperate with the second and fourth inner surfaces of the first and second housing to form the annular channel. 14. An opposed-piston engine, comprising: a first housing including a first inner surface defining a first chamber;a second housing coupled to the first housing and including a second inner surface defining a second chamber;a first piston slidably disposed within the first chamber;a second piston slidably disposed within the second chamber; anda liner coupled to at least one of the first housing and the second housing, the liner including a third inner surface defining a third chamber in fluid communication with the first chamber and the second chamber, the liner being both axially aligned with and disposed radially inward of a portion of at least one of the first and second housings,wherein the first and second pistons are operable to slide within the liner. 15. The opposed-piston engine of claim 14, wherein the first inner surface defines a first diameter, the second inner surface defines a second diameter that is substantially equal to the first diameter, and the third inner surface defines a third diameter that is substantially equal to the first diameter and the second diameter. 16. The opposed-piston engine of claim 15, wherein the first inner surface, the second inner surface, and the third inner surface are coaxial. 17. The opposed-piston engine of claim 15, wherein the first inner surface, the second inner surface, and the third inner surface are substantially flush with one another. 18. The opposed-piston engine of claim 15, wherein the first housing includes a first collar portion having a fourth inner surface defining a fourth diameter that is greater than the first diameter, and wherein the liner is coupled to the fourth inner surface. 19. The opposed-piston engine of claim 18, wherein the second housing includes a second collar portion having a fifth inner surface defining a fifth diameter that is greater than the second diameter, and wherein the liner is coupled to the fifth inner surface. 20. The opposed-piston engine of claim 19, wherein the fourth diameter is substantially equal to the fifth diameter. 21. The opposed-piston engine of claim 14, wherein the first housing and the second housing cooperate to define an annular channel, the liner being disposed within the annular channel. 22. The opposed-piston engine of claim 21, wherein the first inner surface defines a first diameter, the second inner surface defines a second diameter that is substantially equal to the first diameter, and the third inner surface defines a third diameter that is substantially equal to the first diameter and the second diameter. 23. The opposed-piston engine of claim 14, wherein the liner is both axially aligned with and disposed radially inward of a first portion of the first housing and a second portion of the second housing. 24. The opposed-piston engine of claim 19, wherein the fourth and fifth inner surfaces of the first and second collar portions cooperate with one another to at least partially form an annular channel, and the liner is disposed in the annular channel. 25. The opposed-piston engine of claim 19, wherein the first housing and the second housing overlap one another at a junction of the first collar portion and the second collar portion.
