Abstract

The engine comprises an oil pan, an oil storage tank, a first oil way, a second oil way, a first sensor and an engine oil content detector, the oil storage tank and the oil pan are arranged at intervals from top to bottom, the oil storage tank is provided with an oil inlet, the first sensor is arranged in the oil storage tank, and the second sensor is arranged in the second oil way. The first oil way and the second oil way are communicated with the oil storage tank and the oil pan respectively, and a first valve is arranged on the second oil way; the engine oil content detector is arranged in the oil pan and used for detecting the engine oil content in the oil pan; the engine oil content automatic supplementing method comprises the steps that the height value of the liquid level in the oil storage tank is obtained; when the height value is smaller than a first threshold value, a first engine oil content value in the oil pan is obtained; and when the first engine oil content value is smaller than the second threshold value, the first valve is controlled to be opened. By detecting the oil quantity in the oil storage tank and the oil pan, the engine oil content can be accurately detected, and oil can be accurately supplemented.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an automatic replenishment method for engine oil content and a refueling system. Background technique [0002] The lubrication system is an important part of the engine system. The current method of detecting the engine oil content is generally to manually pull the engine oil scale, observe the liquid level, and subjectively observe the engine oil content to determine whether the oil content is within a reasonable range. The prior art has the following defects: the method of detecting the oil content of the oil dipstick is subjective judgment, and the specific oil content value of the engine cannot be accurately determined, and the subjective judgment may have the possibility of misjudgment; when the engine oil is consumed, it is impossible to determine the oil content. Closed-loop supplementation is likely to cause engine oil shortage failure; the layout of the engine oil gauge ...
