Embodiment Construction

[0039] As described in the background technology, although there are also methods to increase the temperature rise rate of engine lubricating oil in the prior art, such as by designing the oil pan of the engine as an oil separation pool to achieve this purpose, there is a baffle in the oil separation pool, which can Most of the cold oil is separated from the hot oil that the engine needs to draw. However, the research of the inventors has found that this structure of the oil separation pool faces a series of problems: firstly, the effect of isolating the cold engine oil and the hot engine oil through the oil separation pool is not good. On the one hand, the oil returned from the crankcase will enter each sub-pool of the oil separation pool, resulting in a small amount of cold engine oil mixed with hot engine oil; Transfer, poor insulation. Secondly, physical barriers such as baffles, valves, etc. set in the oil separation tank will reduce the ability of the engine oil to supp...

Abstract

The invention discloses a liquid level adjusting device and a liquid level monitoring method, an engine lubricating system and a method for adjusting the liquid level of lubricating oil, a vehicle transmission lubricating system and a lubricating oil replacement system. The liquid level adjusting device comprises a first liquid storage tank, a second liquid storage tank and an air pressure adjusting device, wherein the second liquid storage tank is sealed, the first liquid storage tank and the second liquid storage tank are connected through a transmission component; and the air pressure adjusting device is connected with the second liquid storage tank and used for adjusting the air pressure in the second liquid storage tank, so that liquid stored in the first liquid storage tank and the second liquid storage tank flows interactively through the transmission component, and thus the heights of the liquid level in the first liquid storage tank and the liquid level in the second liquid storage tank can be adjusted. According to the engine lubricating system, through the air pressure adjusting device, when an engine is started, part of lubricating oil in the first liquid storage tank flows into the second liquid storage tank, so that the amount of lubricating oil participating in lubricating circulation of the engine is reduced, the heating speed of the lubricating oil is increased, and the friction force and the carbon dioxide emission amount of the engine are reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a liquid level regulating device and a method for monitoring the liquid level, an engine lubricating system and a method for regulating the lubricating oil level, a vehicle transmission lubricating system, and a lubricating oil replacement system. Background technique [0002] Engine oil is also called lubricating oil, which can form a protective oil film on the surface of each friction pair of the engine, thereby reducing friction damage (abbreviated as wear) between parts and prolonging the service life of the engine. In order to ensure that the lubricating oil can form an oil film normally, it is necessary to ensure that the kinematic viscosity of the lubricating oil is suitable and the working temperature is suitable, that is, the temperature of the lubricating oil needs to be raised to the ideal working temperature range. [0003] Low-temperature engine oil has a high viscos...
