öljynjakelujärjestelmä

öljynjakelujärjestelmä is the Finnish term for an oil distribution system. This system is crucial in many engines, particularly internal combustion engines, to ensure proper lubrication of moving parts. The primary function of an oil distribution system is to deliver lubricating oil from the oil sump to all critical components, such as bearings, pistons, camshafts, and crankshafts.

The system typically begins with an oil pump, which draws oil from the sump. This pump is usually driven by the engine's crankshaft or camshaft. The pressurized oil then flows through an oil filter, which removes impurities and contaminants that could damage engine components. After filtration, the oil is directed through a network of oil passages and channels within the engine block and cylinder head.

In many systems, a pressure relief valve is incorporated to regulate the oil pressure, preventing excessive pressure buildup that could damage seals or the oil pump itself. Some systems also feature an oil cooler to manage the oil temperature, especially under high operating loads. The design and complexity of an oil distribution system can vary significantly depending on the engine type, its size, and its intended application. Proper functioning of the oil distribution system is essential for engine longevity and performance, as inadequate lubrication can lead to rapid wear and catastrophic engine failure.
