Description

Integrated oil quality monitoring device

technical field

The utility model relates to the field of engines, in particular to an integrated oil quality monitoring device.

Background technique

During the working process of the internal combustion engine, moving parts such as crankshaft, piston, connecting rod, camshaft, gear transmission system, valve train and other parts usually require lubricating oil with a certain flow rate for lubrication and cooling. The degree of strengthening of the internal combustion engine and the characteristics of the working conditions are different, and the replacement cycle of the lubricating oil is also different. When the working condition of the internal combustion engine is bad, the lubricating oil is prone to aging in a short period of time, which affects the lubrication effect. In addition, under unpredictable circumstances, when water, fuel oil, or other liquid and solid particles enter the lubricating oil, it will have a great impact on the lubricating performance of the lubricating oil. High temperature and even fatigue fracture failure will seriously affect the continuous and safe operation of the internal combustion engine. To this end, there is an organic oil quality test sensor, which can monitor changes in oil quality. For example, it can monitor whether the oil contains non-lubricating oil liquids such as water, whether it contains particles, and whether the PH value exceeds the allowable range, so as to ensure the lubricating oil. Quality, to ensure the safe lubrication of internal combustion engines.

The existing oil quality sensor is usually installed in the main oil passage of the lubricating oil of the internal combustion engine, which is usually located on the body, and the lubricating oil of the crankshaft, camshaft, supercharger and other components of the internal combustion engine is usually taken from the main oil passage. The monitoring process is as follows: the internal combustion engine starts to start and completes the warm-up. Limited by the measurement principle of the traditional oil quality sensor, a certain flow rate or temperature is established in the lubrication system, and the oil quality sensor can start to monitor the lubricating oil. The monitoring value under this condition to be effective. The problem is that before the internal combustion engine is started, the lubricating oil in the oil pan of the internal combustion engine has been mixed with water, or hard particles, or the pH value has changed. After a certain flow rate and temperature, this period of time is a blank period for the monitoring of lubricating oil, that is, during this period, the lubricating oil with poor quality will not be able to form a good lubricating oil film, which will cause wear and tear to the moving parts of the internal combustion engine. .

The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

FIG. 1 is a schematic structural diagram of an integrated oil quality monitoring device according to an embodiment of the present invention.

Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

Unless expressly stated otherwise, throughout the specification and claims, the term "comprising" or its conjugations such as "comprising" or "comprising" and the like will be understood to include the stated elements or components, and Other elements or other components are not excluded.

As shown in FIG. 1 , the specific structure of the integrated oil quality monitoring device according to the preferred embodiment of the present invention includes: a box 4 , a lubricating oil sampling pipeline, an oil quality sensor, a heater 3 and an electric pump 5 . Wherein, the lubricating oil sampling pipeline is arranged in the box body 4, and its two ends protrude from the box body 4, and are respectively communicated with the lubricating oil of the oil pan. The oil quality sensor, heater 3 and electric pump 5 are arranged on the lubricating oil sampling pipeline. Taking oil directly from the oil pan can monitor the abnormality of the lubricating oil in a short period of time. For example, the coolant flows into the lubricating oil of the oil pan, or the abnormal wear of some moving parts causes more metal powder to enter. in the lubricating oil of the oil pan. When these abnormal conditions are detected, an alarm will be given through relevant settings and equipment. It can monitor the oil quality of the internal combustion engine before starting, and avoid the hidden problems caused by monitoring the quality of the lubricating oil after the internal combustion engine is started.
