Description
Technical Field
The invention relates to the field of engine oil dilution detection, in particular to an engine oil dilution detection device and a detection method.
Background
In response to national fuel consumption regulations and energy crisis, more and more host plants are developing direct injection supercharger gasoline engines to reduce engine fuel consumption. The risk of engine oil dilution is increased by the fact that the direct injection engine is high in power-up and high in detonation pressure, fuel is directly sprayed into a cylinder through a fuel injector, and the like. The main reason for the dilution of the oil is that the fuel enters the crankcase and mixes with the oil, resulting in a decrease in the viscosity of the oil. The reduced viscosity of the engine oil can lead to poor lubrication of moving parts such as crankshafts, camshafts and timing chains, and can lead to damage of the engine in severe cases.
The current engine oil dilution detection methods include an off-line detection method and an on-line detection method. The off-line detection method generally collects an engine oil sample after the finished vehicle test is completed, and tests the components of the engine oil sample by a pyrolysis weighing method, a gas chromatograph detection method, a gravimetric analysis method, a viscosity detection method and the like. The viscosity detection method comprises the steps of heating engine oil to a specified temperature through equipment, calculating the flow rate of the engine oil by using a constant volume flow rate cup and timing equipment, and finally calculating the viscosity of the engine oil according to the flow rate by using a formula. The off-line detection method needs more equipment parts, is complex to operate, is guaranteed by personnel during timing, and is low in precision. Viscosity measurements have specific requirements on the temperature of the oil, which requires heating of the oil. In the heating process, impurities such as fuel oil, moisture and the like in the engine oil can volatilize a part, so that the testing precision is influenced, an external power supply is required, and the field use of testers is not facilitated.

In the scheme of this application, because engine oil dilution detection device includes volume bottle 100, vacuum pump 200, oil feed subassembly and display recorder 400. The air-extracting end of the vacuum pump 200 is connected to the air hole of the volume bottle 100 to extract the air in the volume bottle 100 so that the volume bottle 100 is in a preset negative pressure state. The oil feeding assembly comprises an oil pipe 300 and a brush switch 310 arranged on the oil pipe 300, the brush switch 310 is used for opening or closing the oil pipe 300, and the brush switch 310 is electrically connected with the timing unit through a signal wire 420.

Display recorder 400 is used to display the temperature of the oil entering oil pipe 300 and the on time of brush switch 310. During actual operation, the display recorder 400 is reset, the brush switch 310 is in a closed state, the vacuum pump 200 is controlled to work, the volume bottle 100 is in a preset negative pressure state, then the first end of the oil pipe 300 is inserted into oil to be detected, the brush switch 310 is opened, the volume bottle 100 in the negative pressure state can suck the oil to be detected into the volume bottle 100 through the oil pipe 300, a detector observes the oil amount in the volume bottle 100, and the brush switch 310 is closed when the oil amount reaches a preset value. Therefore, the time required for the oil to be detected to enter the volume bottle 100 under the specific pressure to reach the preset amount at a certain temperature can be obtained, and the recorded temperature data and the recorded time data are substituted into the database to be compared to obtain the dilution degree of the engine oil.
