Typical example
Oil pressure for the engine lubrication system is provided by an engine mounted oil pump (6). The engine oil pump (6) is located on the bottom of the cylinder block and within the oil pan (4). Lubricating oil from the oil pan (4) flows through a strainer (5) and a pipe to the inlet side of the engine oil pump (6). The engine oil pump (6) is driven from the crankshaft through an idler gear.The engine oil pump (6) has an inner rotor with six lobes. The inner rotor is mounted to a shaft which also carries the drive gear. The engine oil pump (6) also has an outer annulus with seven lobes. The axis of rotation of the annulus is offset relative to the rotor. The volume between the lobes of the rotor and the annulus increases on the right-hand side when the rotor is rotated. The increasing space between the lobes of the rotor and the annulus causes a reduction in pressure. This reduction in oil pressure causes oil to flow from the oil pan (4), through the oil strainer (5) and into the oil pump (6).The volume between the lobes of the rotor and annulus decreases on the left-hand side when the rotor is rotated. The decreasing space between the lobes of the rotor and annulus causes oil to be pressurized. The increase in oil pressure causes oil to flow from the oil pump outlet into the engine lubrication system.The oil flows from the oil pump (6) through holes in the cylinder block to a plate type oil cooler (1). The plate type oil cooler (1) is located on the left-hand side of the engine.From the oil cooler (1), the oil returns through a drilling in the cylinder block to the filter head.The oil flows from the oil filter (3) through a passage to the oil gallery. The oil gallery is drilled through the total length of the left side of the cylinder block. If the oil filter (3) is on the right side of the engine, the oil flows through a pipe assembly. The pipe assembly is mounted to the lower face of the cylinder block.Lubricating oil from the oil gallery flows through passages to the main bearings of the crankshaft. The oil flows through the passages in the crankshaft to the connecting rod bearing journals. The pistons and the cylinder bores are lubricated by the lubricating oil.Lubricating oil from the main bearings flows through passages in the cylinder block to the journals of the camshaft. Then, the oil flows from the second journal of the camshaft at a reduced pressure to the cylinder head. The oil then flows into the rocker arm bushing of the rocker arm levers. The valve stems, the valve springs and the valve lifters are lubricated by the lubricating oil.The hub of the idler gear is lubricated by oil from the oil gallery. The timing gears are lubricated by the lubricating oil.The turbocharger is lubricated by oil via a drilled passage through the cylinder block. An external line from the engine block supplies oil to the turbocharger. The oil then flows through a line to the oil pan (4).Piston cooling jets (2) are installed in the engine. The piston cooling jets (2) are supplied with the oil from the oil gallery. The piston cooling jets (2) spray lubricating oil on the underside of the pistons in order to cool the pistons.
