Problems solved by technology

However, due to the oil pumping effect of the engine oil pump, the adsorption pressure at the oil inlet is very high, and the oil filter is easily adsorbed to the oil inlet. Long-term accumulation at the oil inlet leads to blockage, which prevents lubricating oil from entering the lubricating oil passage, thereby affecting lubrication, and even causing abnormal wear or crankshaft lockup in severe cases

Abstract

The invention discloses an engine pressure lubricating system and an engine with the same.The system comprises an oil pump and an oil inlet channel arranged in an oil pump shell of the oil pump.An engine oil filter screen is arranged on the oil inlet channel.A blocking rib for supporting the engine oil filter screen in the oil suction direction of the oil pump is arranged on the oil pump shell.The engine oil filter screen is blocked by the blocking rib on the oil pump shell, it can be avoided that the engine oil filter screen is close to the oil inlet of the engine oil pump under the excessively large engine oil suction force, it is effectively avoided that impurities are accumulated at the oil inlet and prevent engine oil from entering the oil channel, lubrication is sufficiently ensured, and normal work of the engine is ensured.

Description

technical field [0001] Engine The present invention relates to the field of engines, and in particular to an engine pressure lubrication system and its engine. Background technique [0002] The engine crankcase cover is an important part of the engine block. The oil pump of the existing engine is usually installed inside the crankcase cover. The oil pump is an important component of the engine lubrication system. The ground pressure is sent to the moving surface of the engine parts. The existing large-displacement engines all use the engine oil pump for pressure lubrication. The oil filter screen, the lubricating oil passes through the oil filter screen to filter out impurities and then enters the lubricating oil passage. However, due to the oil pumping effect of the engine oil pump, the adsorption pressure at the oil inlet is very high, and the oil filter is easily adsorbed to the oil inlet. Long-term accumulation at the oil inlet leads to blockage, which prevents lubrica...
