Abstract

The invention discloses a cylinder cover capable of controlling the flow of an oil pump, which comprises an engine lubricating system oil passage and a cylinder cover rear-end oil way which are arranged in the cylinder cover, the tail end of the engine lubricating system oil passage is communicated with the cylinder cover rear-end oil way, the cylinder cover rear-end oil way is communicated with an oil pan, and an electromagnetic valve is arranged on the cylinder cover rear-end oil way. The electromagnetic valve is connected with the ECU; the electromagnetic valve changes the rotation angle to change the engine oil drainage amount according to an ECU instruction; the ECU linearly and dynamically adjusts the rotation angle of the electromagnetic valve according to the real-time working condition data of the engine. The flow-adjustable oil pump has the advantages of reducing fuel consumption, prolonging the service life of the oil, reducing the transmission noise of the oil pump and the like.

Description

Technical field [0001] The present invention relates to the technical field of the internal combustion engine, specifically a cylinder head that controls the flow rate of the oil pump. Background [0002] From the flow curve of the conventional oil pump and the variable flow oil pump with the engine speed, it can be seen that the conventional oil pump outputs the larger flow that the engine does not need at high speed in the engine, and the excessive supply of oil leads to an increase in the number of oil cycles, which is easy to oxidize and deteriorate; while the variable flow oil pump reduces the high speed flow rate in the engine, the number of oil cycles is reduced, and the oil is not easy to oxidize and deteriorate; the variable flow oil pump consumes less power, which can reduce the engine fuel consumption. [0003] Existing controllable flow rotor oil pump, the inner rotor rotation drive the outer rotor, the outer rotor is divided into two parts of the same thickness, wit...
