A rapid detection method for automobile engine oil consumption

Abstract

The invention discloses a method for quickly detecting the oil consumption of an automobile. In the present invention, the oil tank is first cleaned to reduce the detection background, and then the test engine oil without iron and organic ligand compounds and the test engine oil with iron and organic ligand compounds are added to the oil tank successively. , respectively measure the iron ion concentration in the exhaust gas after the combustion of the two test engine oils, and obtain the iron ion concentration difference. According to the regression line between the iron ion concentration difference and the oil consumption per thousand kilometers, the oil consumption per thousand kilometers of the vehicle is obtained, and then the vehicle is judged The degree of "burning engine oil"; the method of the present invention can accurately and timely detect engine oil consumption, has the advantages of short test time, simple equipment structure and strong practicability, and can be used as a basis to establish an accurate result of automobile engine oil consumption The test method can accurately judge the degree of "burning engine oil" of the car.

Description

technical field [0001] The invention relates to automobile engine technology, in particular to a rapid detection method for automobile oil consumption. Background technique [0002] In modern society, automobiles play an increasingly important role in people's daily life and have become an indispensable means of transportation. Therefore, the daily maintenance and maintenance of automobiles can prolong the service life of various parts of automobiles, and understanding the working conditions of automobiles is important. very important. [0003] The engine is a core component of the car, and its working condition is very critical to the normal driving of the car. However, due to the natural wear and tear of the engine and the improper daily maintenance measures of the car owner, the engine will have different degrees of "burning oil" phenomenon, "burning oil". The main manifestation of "oil" is the blue exhaust from the rear of the car when driving, which means that too much...

Problems solved by technology

[0003] The engine is a core component of the car. Its working condition is very important for the normal driving of the car. However, due to the natural wear and tear of the engine and the improper daily maintenance measures of the car owner, the engine will appear "burning oil" to varying degrees. The main manifestation of "engine oil" is that the tail of the car emits blue exhaust gas when driving, which means that too much oil enters the combustion chamber to participate in combustion, and it is also manifested when the oil dipstick detects that the oil consumption is too fast

[0004] The phenomenon of "burning engine oil" is very harmful to the vehicle. It will not only damage the oxygen sensor of the vehicle too quickly, but also lead to increased carbon deposits in the combustion chamber, unstable idling speed, weak acceleration, increased fuel consumption, and excessive exhaust emissions. Due to insufficient lubrication of the engine, the engine will be damaged or even scrapped which is difficult to repair, resulting in a significant increase in maintenance costs and even hidden dangers of accidents

[0005] The traditional method of detecting the oil consumption of automobiles to judge the degree of "burning oil" of automobiles is to conduct a real vehicle driving test of 1000 km on the car, and compare the change of the volume of oil in the oil tank of the car before and after the experiment to obtain the oil consumption per thousand kilometers of the car. Based on this, the degree of "burning engine oil" of the car can be judged. The whole test process takes too long to get the results quickly. This method is time-consuming and labor-intensive.
