Based on the same inventive concept as the display device provided in the foregoing embodiment, the embodiment of the present application further provides a method for detecting oil leakage of a supercharger, which is applied to the oil leakage detection device 100 of a supercharger shown in fig. 1. As shown in fig. 3, the method for detecting oil leakage of a supercharger comprises the following steps:

in step S301, a sample capacitance value of the target electrolyte is determined by a sensor located at the bottom of the pressure end outlet of the turbocharger.

Wherein the target electrolyte is the electrolyte at the bottom of the pressure end air outlet of the turbocharger.

Illustratively, the supercharger oil leakage detection apparatus determines a sample capacitance value of a target electrolyte via a sensor 300 located at the bottom of a pressure end outlet of the turbocharger. Wherein the target electrolyte is the electrolyte at the bottom of the pressure end air outlet of the turbocharger.

Step S302, comparing the sample capacitance value with a preset capacitance range threshold to obtain a comparison result.

Wherein the capacitance range threshold comprises a first target capacitance value and a second target capacitance value; the first target capacitance value is greater than the second target capacitance value.

In particular, in the embodiment of the present application, a preset capacitance range threshold may be set for the turbocharger. The larger the dielectric constant is, the stronger the conductivity of the characterization object is, the dielectric constant of water is about 81, the dielectric constant of oil is about 3-5, the dielectric constant of air is about 1, capacitance values formed when oil in different states are used as intermediate media of the capacitor are different, the intermediate dielectric media in the collecting device can be basically divided into air, water, oil-water mixture and engine oil, the difference of the dielectric constants is large, and according to the mapping relation between the dielectric constants and the capacitance value change, when the oil leakage at the pressure end of the supercharger reaches a certain limit value, the corresponding capacitance reaches a certain limit value.

Therefore, the present embodiment sets a capacitance range threshold for the turbocharger, where the capacitance range threshold includes a first target capacitance value and a second target capacitance value, the first target capacitance value is greater than the second target capacitance value, for example, the preset capacitance range threshold is assumed to be "1800 millifarads to 3000 millifarads", where the first target capacitance value and the second target capacitance value are 3000 millifarads and 1800 millifarads, respectively. Assuming that the measured sample capacitance value is 2000 millifarads, the sample capacitance value is compared with a preset capacitance range threshold value of 1800 millifarads to 3000 millifarads to obtain a comparison result. With the comparison, it is possible to obtain a comparison result of "2000 millifarads is not less than 1800 millifarads and not more than 3000 millifarads".

In some embodiments of the present application, the capacitance range threshold of the turbocharger of the engine may also be calibrated via the gantry under different operating conditions. When the vehicle runs under different working conditions, the ECU can select the corresponding capacitance range threshold according to the specific working conditions.

Step S303, if the comparison result is that the sample capacitance value is not smaller than the second target capacitance value and not larger than the first target capacitance value, it is determined that the oil leakage of the supercharger occurs.

For example, since the sample capacitance value is 2000 millifarads, the preset capacitance range threshold value is 1800 millifarads to 3000 millifarads, and the comparison result meets the condition that the sample capacitance value is not smaller than the second target capacitance value and not larger than the first target capacitance value, it is determined that the oil leakage of the supercharger occurs.

According to the method for detecting oil leakage of the supercharger, whether the supercharger leaks oil is judged by measuring the capacitance value of the electrolyte at the bottom of the air outlet of the pressure end of the turbocharger, so that whether the pressure end of the supercharger leaks oil is monitored in real time, and the efficiency of detecting oil leakage of the supercharger can be improved.

In one possible implementation, the cavity further comprises a siphon chamber; the interface of the oil storage cavity and the siphon chamber is the interface of the pipe wall of the pressure end air outlet and the cavity; an oil inlet and an oil outlet are arranged on the side wall of the siphon chamber.

In a possible realization, the oil inlet and the oil outlet are arranged in the air flow direction at the pressure end air outlet position.

According to the method, the target electrolyte is collected through the oil storage cavity of the collection structure, the collection structure is divided into the oil storage cavity, the oil inlet and the oil outlet, the capacitance sensor is mounted at the bottom of the oil storage cavity, the oil storage cavity is provided with a certain depth and used for storing the dielectric medium, the size of the oil inlet is slightly larger than that of the oil outlet, the lower ends of the oil inlet and the oil outlet are flush with the pipe wall, when the oil leakage amount of the pressure end is small, gas after the engine oil flowing into the oil storage cavity is pressed is sucked into a cylinder through the oil outlet, when the oil leakage amount of the pressure end is large, the oil inlet amount is larger than the oil outlet amount, the dielectric medium can be stored in the oil storage cavity, the capacitance measurement is relatively stable, the accuracy of the oil leakage detection of the supercharger can be improved, whether the pressure end of the supercharger leaks oil or not is monitored in real time, and the efficiency of the oil leakage detection of the supercharger is improved
