In addition, in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are for illustration and explanation only, and are not intended to limit the present application, and embodiments and features of embodiments of the present application may be combined with each other without conflict.
The method for determining the oil pressure relief point according to the present application will be described in detail with reference to the following examples. Fig. 1 is a flowchart of a method for determining an oil pressure relief point according to an embodiment of the present application, where the method includes the following steps.
In step 101, the oil flow of the main bearing oil passage to be detected at the preset oil temperature is sampled.
In some embodiments, the oil flow of the main bearing oil passage at the preset oil temperature may be obtained according to the preset time interval by integrating the ultrasonic flowmeter disposed at one side of the main bearing oil passage.
For example, as shown in fig. 2, fig. 2 is a schematic structural diagram of a main bearing oil duct provided in an embodiment of the present application, an ultrasonic flowmeter is disposed on one side of the main bearing oil duct and a connecting rod bearing oil duct, electric energy is converted into ultrasonic energy by an ultrasonic transmitting transducer of the ultrasonic flowmeter, the ultrasonic energy is transmitted to flowing engine oil, a receiver is disposed on the other side of the oil duct, an ultrasonic signal is received, signals generated when the ultrasonic wave is sent and received are recorded by an electronic control unit (Electronic Control Unit, ECU), and the signals are amplified by an electronic circuit and converted into an electric signal representing flow to be supplied to a display and calculation instrument of the ultrasonic flowmeter for display and calculation, and then based on a calculation result, the engine oil flow of the main bearing oil duct is obtained.
In step 102, a relief value of the oil pressure corresponding to the sampled oil flow with respect to the oil pressure corresponding to the reference oil flow is determined based on a predetermined correspondence between the oil pressure and the main bearing oil passage oil flow.
In specific implementation, an engine oil pressure interval can be preset when the engine oil pressure is normal, a group of engine oil pressures and main bearing oil duct engine oil flows corresponding to the engine oil pressures are collected at each interval set time, and then the corresponding relation between the engine oil pressures and the main bearing oil duct engine oil flows is predetermined in a mode of fitting and mapping a relation curve of the corresponding relation between the engine oil pressures and the main bearing oil duct engine oil flows based on the collected engine oil pressures and the corresponding main bearing oil duct engine oil flows.
For example, when the oil pressure is normal, the preset oil pressure interval is [100Kpa,500Kpa ]]Collecting a group of oil pressure at the moment and oil flow of the main bearing oil duct at the moment at each interval of 30s, and then fitting the collected groups of values to obtain a relation curve for mapping the corresponding relation between the oil pressure and the oil flow of the main bearing oil duct, wherein the relation curve is p=aq n +bQ n-1 +c, wherein P represents the oil pressure, Q represents the main bearing oil duct oil flow, and a, b and c represent preset parameters.
In specific implementation, after the corresponding relation between the engine oil pressure and the engine oil flow of the main bearing oil duct is determined, a flow change value of the engine oil flow of the main bearing oil duct can be determined based on the sampled engine oil flow and the previously acquired reference engine oil flow of the main bearing oil duct, and a pressure relief value of the engine oil pressure of the main bearing oil duct corresponding to the flow change value is obtained based on the corresponding relation between the determined flow change value and the corresponding pressure relief value in advance according to the corresponding relation between the engine oil pressure and the engine oil flow of the main bearing oil duct.
It should be noted that the reference oil flow rate of the main bearing oil passage refers to a pre-selected oil flow rate of the main bearing oil passage when the oil pressure is normal and at a preset oil temperature.
In the implementation, after the corresponding relation between the oil pressure and the oil flow of the main bearing oil duct is determined, the first oil pressure corresponding to the sampled oil flow can be determined based on the corresponding relation between the predetermined oil pressure and the oil flow of the main bearing oil duct, the second oil pressure corresponding to the reference oil flow obtained before is determined based on the corresponding relation between the predetermined oil pressure and the oil flow of the main bearing oil duct, and then the corresponding pressure relief value is determined according to the first oil pressure and the second oil pressure.
For example, the sampled oil flow is brought into a corresponding relation curve of the oil pressure and the oil flow of the main bearing oil duct, a first oil pressure P1 corresponding to the sampled oil flow is determined, the reference oil flow is brought into a corresponding relation curve of the oil pressure and the oil flow of the main bearing oil duct, a second oil pressure P2 corresponding to the reference oil flow is determined, and then the difference between P2 and P1 is determined as a relief value of the oil pressure.
In step 103, it is determined whether or not the main bearing oil passage is depressurized based on the depressurized value of the oil pressure of the main bearing oil passage.
In specific implementation, a pressure relief threshold of the main bearing oil duct can be set, for example, the pressure relief threshold is set to be 100KPa, if the pressure relief value of the engine oil of the main bearing oil duct reaches the set pressure relief threshold, the main bearing oil duct is determined to relieve pressure, and if the pressure relief value of the engine oil does not reach the set pressure relief threshold, the main bearing oil duct is determined to not relieve pressure.
Therefore, whether the problem of engine oil pressure relief caused by the increase of the clearance of the moving part due to the failure of the main bearing oil duct is solved, convenience is brought to the investigation of the engine oil pressure relief point, the complexity and invalidity caused by the disassembly and inspection of parts in the engine are solved, and the efficiency of maintenance work is improved.
Fig. 3 is a flowchart of another method for determining an oil pressure relief point according to an embodiment of the present application, where the method includes the following steps.
In step 301, the oil flow of the main bearing oil passage to be detected at a preset oil temperature is sampled.
In step 302, a relief value of the oil pressure corresponding to the sampled oil flow with respect to the oil pressure corresponding to the reference oil flow is determined based on a predetermined correspondence between the oil pressure and the main bearing oil passage oil flow.
For implementation, reference may be made to step 102, which is not described herein.
In step 303, it is determined whether the oil pressure relief value of the main bearing oil passage reaches a set relief threshold, if so, step 304 is entered, and if not, step 305 is entered.
In step 304, it is determined that the main bearing oil passage is depressurized.
In step 305, it is determined that the main bearing oil passage is not depressurized.
In the implementation, the engine oil pressure can be monitored, when the engine oil pressure is monitored to be decompressed, the main bearing oil duct is positioned to be a decompression point if the main bearing oil duct is determined to be decompressed according to the decompression value of the engine oil pressure, when the engine oil pressure is monitored to be decompressed, the main bearing oil duct is positioned to be a non-decompression point if the main bearing oil duct is determined to not be decompressed according to the decompression value of the engine oil pressure, and then other fault points which can possibly lead to decompression of the engine oil pressure, such as whether an engine oil pump filter screen is blocked, can be further checked.
Based on the same technical concept, the embodiment of the application also provides an engine oil pressure relief point determining device, and the principle of solving the problem of the engine oil pressure relief point determining device is similar to that of the engine oil pressure relief point determining method, so that the implementation of the engine oil pressure relief point determining device can be referred to the implementation of the engine oil pressure relief point determining method, and repeated parts are not repeated.
