Which of the diesel engine cylinder liners listed has internal cooling water passages?
β’ Differences between wet liners and dry liners in diesel engines β’ How cooling water flows around or through cylinder liners β’ Meaning of integral water jacket versus fins used only for air cooling
β’ Think about which liner designs are intended to be in direct contact with cooling water rather than just surrounded by metal β’ Ask yourself: do fins (internal or external) usually indicate air cooling or water passages? β’ Consider whether an integral water-jacket means the water flows through the liner itself or around a separate space in the block
β’ Identify which options are commonly associated with air-cooled engines β’ Decide which designs place cooling water in direct contact with the liner wall β’ Clarify in your mind whether water passages inside the liner are different from a water jacket formed in the engine block
