The document discusses the lubrication system of a modern engine. It aims to teach students the main components of an engine's lubrication system, including the oil pump, filters, galleries, bearings and more. An investigation identifies these components on a Ford 1600 engine, noting the types and positions of the oil pump, filters, pressure relief valve and other parts.
