The present application provides an engine oil pump control method, device, system and engine. The method obtains the working inclination angle of the vehicle and the engine oil pressure of the engine; determines the preset critical inclination angle and preset pressure of the engine, and the preset critical inclination angle and preset pressure The critical inclination and critical pressure of the first oil pump of the engine; according to the working inclination, oil pressure, preset critical inclination and preset pressure, control the working state of the second oil pump so that the lubrication system can supply oil normally, according to the vehicle The inclination angle of the vehicle and the oil pressure of the engine can control whether the second oil pump of the engine is turned on. The second oil pump of the engine is only turned on under the preset working conditions determined according to the inclination angle of the vehicle and the oil pressure of the engine, so that there is no need to turn on multiple oil pumps at the same time. Reduced engine power loss.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine oil pump control method, device, system and engine. Background technique [0002] When the vehicle is running, the engine of the vehicle needs to absorb oil from the oil pan through the oil pump to ensure the normal running of the vehicle. When driving up and downhill or when the vehicle is required to work at a large inclination angle, a large amount of engine oil gathers in the small head of the oil pan, and the oil suction port of the oil filter of the oil pump cannot completely penetrate into the engine oil, causing the oil pump to suck air, resulting in engine scratching and cylinder scuffing , affecting the safety performance and service life of the vehicle. [0003] In the related technology, in order to adapt to the change of the inclination angle of the vehicle, the engine usually adopts a dual oil pump lubrication system of the main oil pump and the auxiliary...
