Problems solved by technology

[0002] Oil emulsification and oil dilution have always been a persistent problem for major automobile manufacturers, especially in extremely cold regions, where the problems caused by long-term short-distance driving conditions are particularly obvious, not only affecting the lubrication effect, but even in extreme cases. Ice builds up and clogs the oil suction line, causing insufficient oil pressure, which can damage the engine
At present, this phenomenon cannot be eliminated, but can only be alleviated. Therefore, timely monitoring of the severity of oil emulsification and oil dilution, and rational control of them have become important issues for various automobile manufacturers.

Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] When the engine is running, there is direct contact between the surfaces of relatively moving parts, and in this constant "scratching", wear occurs immediately, and at the same time, this phenomenon will also erode part of the power. In order to improve the life of the engine, the lubrication system of the engine is always being improved. In the lubrication system of the engine, engine oil plays a very important role. It can reduce the degree of wear between mechanical parts and reduce the power loss inside the engine.

[0049] The emulsified engine oil contains water and air bubbles, which will obviously affect the performance of the engine oil in terms of lubrication, cleaning, and heat dissipation. Emulsification is the process by which two immiscible l...

Abstract

The invention provides a method and device for controlling engine oil emulsification and fuel oil dilution. The method for controlling engine oil emulsification and fuel oil dilution comprises the steps that the environment temperature and automobile running behavior features are monitored; according to the environment temperature and the automobile running behavior features, the severity degree of engine oil emulsification and fuel oil dilution is obtained; and if the evaluation value of the severity degree of engine oil emulsification and fuel oil dilution exceeds a frequency threshold value, prompt information and / or a solution to relieving engine oil emulsification and fuel oil dilution are / is displayed. By the adoption of the method and device for controlling engine oil emulsification and fuel oil dilution, the severity degree of engine oil emulsification and fuel oil dilution can be judged out in time, a user can be reminded, the solution can be provided for the user so as to avoid aggravation of engine oil emulsification and fuel oil dilution, and therefore an engine can be effectively protected; and, an existing sensor is utilized, the cost is not increased, and the method and device for controlling engine oil emulsification and fuel oil dilution have good economical efficiency and high applicability.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a method and device for controlling engine oil emulsification and fuel dilution. Background technique [0002] Oil emulsification and oil dilution have always been a persistent problem for major automobile manufacturers, especially in extremely cold regions, where the problems caused by long-term short-distance driving conditions are particularly obvious, not only affecting the lubrication effect, but even in extreme cases. Ice builds up and blocks the oil suction line, causing insufficient oil pressure and damaging the engine. At present, this phenomenon cannot be eliminated, but can only be alleviated. Therefore, timely monitoring of the severity of oil emulsification and oil dilution, and rational control of them have become important issues for various automobile manufacturers. Contents of the invention [0003] In order to rationally control the phenomenon of engine oil ...
