Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, where the described embodiments are merely exemplary implementations, but not all implementations of the application. Those skilled in the art can combine embodiments of the application to obtain other embodiments without inventive faculty, and such embodiments are also within the scope of the application.
The upper engine has limited arrangement space above the chassis, so the oil tank of the engine can only be arranged below the chassis. In order to meet the requirement of the engine on the operation time, the capacity of the oil tank is large, the height difference between the liquid level of the oil tank and the oil injection pump of the engine is increased, the oil quantity pumped by the oil injection pump is small, the oil inlet pressure of the engine is reduced, and the normal operation of the engine is influenced.
In order to solve the problems, a fuel pump can be added in a fuel supply pipeline between a fuel tank and a fuel injection pump at present, and the main function of the fuel pump is to suck fuel out of the fuel tank, pressurize the fuel and then convey the fuel into the fuel supply pipeline, so that the fuel supply pressure of an engine can be improved. However, the fuel supply pressure of the fuel pump is confirmed to be a fixed value according to the height difference between the highest point and the lowest point of the fuel tank liquid level and the fuel injection pump of the engine. When the fuel pump is used in plain areas, the fuel pump can meet the use requirement of the fuel inlet pressure of the engine, but with the increase of the altitude, the atmospheric pressure gradually drops, and the fuel supply pressure of the fuel pump can not meet the use requirement of the fuel inlet pressure of the engine. If the oil supply pressure of the fuel pump is set to be too low, the oil inlet pressure of the engine is too low, the oil inlet amount is insufficient, the problem of insufficient engine power can occur, and the engine can be stopped immediately when serious; if the oil supply pressure of the fuel pump is set too high, the oil inlet pressure of the engine is too high, the oil inlet quantity is too high, the valve flushing failure of the engine can be caused, the torque limit and the power limit are triggered, and the normal use requirement of the engine can not be met.
Based on the above, the embodiment of the application provides a control method of the oil supply pressure of an engine, so as to control the oil supply pressure of the engine to ensure the normal operation of the engine. In particular, the oil supply pressure of the engine may be controlled in a manner that obtains an operating condition of the engine, and a preset condition for controlling the oil supply pressure of the engine, which indicates a condition of the oil supply pressure corresponding to normal operation of the engine, is obtained based on the operating condition of the engine. Therefore, the oil supply pressure of the engine can be controlled based on the preset condition so as to ensure the normal operation of the engine. The control method of the engine oil supply pressure can be used for determining the preset condition for controlling the oil supply pressure by combining the operation working condition of the engine so as to control the oil supply pressure according to the preset condition and realize the normal operation of the engine.
In order to facilitate understanding of the technical solution provided by the present application, the following description will be made with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a method for controlling an engine oil supply pressure according to an embodiment of the present application.
The method may be performed by a controller of the engine, where the controller may be an electronic device or other device. The method may comprise the steps of:
s101: and acquiring the operation condition of the engine.
Under different operating conditions, the oil supply pressure required by the engine for realizing normal operation is different, so that the oil supply pressure of the engine is controlled more accurately to ensure that the engine is normally operated under different operating conditions, and the current operating condition of the engine is required to be acquired first. The fuel supply pressure of the engine represents the fuel supply pressure of the fuel pump in the engine.
Alternatively, the operating conditions may include: before and after engine start. That is, the embodiment of the application can control the oil supply pressure of the engine according to the starting state of the engine so as to realize normal starting of the engine and normal running after the starting.
S102: and acquiring preset conditions for controlling the oil supply pressure of the engine based on the operation working condition.
After determining the operation condition of the engine, a corresponding preset condition for controlling the oil supply pressure of the engine can be obtained according to the operation condition, wherein the preset condition indicates the corresponding oil supply pressure condition when the engine is normally operated. That is, different operating conditions of the engine correspond to different supply pressure control strategies.
S103: the oil supply pressure of the engine is controlled based on preset conditions.
After the preset condition corresponding to the operation condition of the engine is obtained, the oil supply pressure of the engine can be controlled according to the preset condition.
As can be seen from the above embodiments, the operation conditions of the engine can be divided into the operation conditions before the engine is started and the operation conditions after the engine is started, and the control principle of the oil supply pressure will be described below with respect to the operation conditions before the engine is started and after the engine is started, respectively.
Before the engine starts, in order to ensure that the engine can start normally, the oil supply pressure of the engine needs to be controlled to be in a reasonable range. Specifically, under the operating condition, the preset condition for controlling the oil supply pressure of the engine may be a correlation between the altitude of the external environment, the liquid level of the oil tank, and the oil supply pressure, that is, the corresponding oil supply pressure may be determined according to the altitude of the external environment and the liquid level of the oil tank. When the altitude of the external environment is higher, the atmospheric pressure gradually decreases, and compared with the plain environment, the oil inlet pressure applied to the oil injection pump is reduced, so that the oil supply pressure of the fuel pump needs to be increased, and the oil injection pump is ensured to have sufficient oil inlet pressure under the action of the oil supply pressure and the atmospheric pressure. That is, the higher the altitude of the external environment, the greater the fuel supply pressure of the fuel pump needs to be controlled. When the liquid level of the oil tank is lower, the amount of the extracted fuel is reduced under the same oil supply pressure, so that the oil supply pressure of the fuel pump is required to be increased at the moment, so that the fuel pump can extract enough fuel, the fuel pump is provided for the fuel injection pump through the oil supply pipeline, the fuel injection pump is ensured to have enough fuel to be injected into an engine cylinder, and the engine is started normally. That is, the lower the level of the fuel tank, the greater the fuel supply pressure of the fuel pump needs to be controlled. Therefore, after the association relation is acquired, the altitude of the current external environment of the engine and the current liquid level of the oil tank can be acquired, and then the oil supply pressure corresponding to the current altitude and the current liquid level of the oil tank is determined based on the association relation, so that the oil pump can be controlled to provide the oil supply pressure for the engine.
Alternatively, the association relationship may be represented in the form of a graph or may be represented in the form of a table. For example, when the correlation is a graph, the abscissa is the altitude, the ordinate is the inverse of the tank level height, the point of the graph represents the fuel supply pressure corresponding to a certain altitude in the abscissa and a certain tank level height in the ordinate, and the fuel supply pressure represented by the graph tends to increase with the increase of the altitude or with the increase of the inverse of the tank level height (i.e., the tank level height decreases). Alternatively, when the association is a table, the rows of the table may be the altitudes, the columns of the table may be the inverse of the tank level heights, and the cells in the table represent the fuel supply pressures corresponding to a certain altitude in the rows, a certain tank level height in the columns.
The preset range of fueling pressures that will cause the engine to operate properly may be predetermined for the type of engine in combination with historical experience while the engine is running. Then the fueling pressure of the engine may be controlled in real time in accordance with the preset fueling pressure range after the engine is started. Specifically, when the engine is started to run, the controller can acquire the current oil supply pressure of the engine and judge whether the current oil supply pressure is within a preset oil supply pressure range, if so, the oil supply pressure does not need to be regulated, and the engine can run normally; if not, the oil supply pressure of the engine needs to be adjusted so that the adjusted oil supply pressure is within a preset oil supply pressure range. Wherein, the oil supply pressure of the engine can be obtained through measurement of a pressure sensor.
In one possible implementation, the fuel supply pressure of the fuel pump may be changed by adjusting an electronic pressure relief valve of the fuel pump, where a pressure value corresponding to the electronic pressure relief valve is indicative of the fuel supply pressure of the fuel pump. When the current oil supply pressure of the engine is smaller than the minimum value of the preset oil supply pressure range, the pressure value corresponding to the electronic pressure relief valve can be increased to the target pressure value, so that the oil supply pressure of the fuel pump is increased to the target pressure. The target pressure is within a preset oil supply pressure range, and the specific value of the target pressure is not limited in this embodiment, for example, the target pressure may be set to be an average value of the maximum oil supply pressure and the minimum oil supply pressure in the preset oil supply pressure range. When the current oil supply pressure of the engine is larger than the maximum value of the preset oil supply pressure range, the pressure value corresponding to the electronic pressure relief valve can be reduced to a target pressure value, so that the oil supply pressure of the fuel pump is reduced to the target pressure, and the normal operation of the engine is ensured.
The control method of the engine oil supply pressure can be used for determining the preset condition for controlling the oil supply pressure according to the operation working condition of the engine so as to control the oil supply pressure according to the preset condition, and the oil supply pressure of the engine can be regulated in real time in the operation process of the engine so as to realize the normal operation of the engine.
The control principle of the engine oil supply pressure will be described below in connection with a specific application scenario.
Referring to fig. 2, fig. 2 is a schematic diagram of a control system for engine oil supply pressure according to an embodiment of the present application.
The system 200 includes: an engine 201, a controller 202, a fuel pump 203, and a fuel tank 204;
the controller 202 may control the start of the engine 201 through the start button, before the engine 201 is started, the controller 202 may obtain the current altitude of the external environment and the current liquid level of the oil tank 204, and then determine the oil supply pressure corresponding to the current altitude, the current liquid level of the oil tank 204 and the oil supply pressure according to the correlation between the altitude of the external environment, the liquid level of the oil tank 204 and the oil supply pressure, so that the fuel pump 203 may extract the fuel of the oil tank 204 according to the determined oil supply pressure, and provide the fuel to the fuel injection pump of the engine 201 through the oil supply pipeline, that is, make the oil supply pressure in the oil supply pipeline be the determined oil supply pressure.
After the fuel pump 203 provides the determined fuel supply pressure to the engine 201, the controller 202 may control the engine 201 to start via a start button. During operation of the engine 201, the controller 202 may acquire the fuel supply pressure of the fuel pump 203 in real time and determine whether the actual fuel supply pressure is within a preset fuel supply pressure range, and if not, may change the fuel supply pressure of the fuel pump 203 by controlling an electronic pressure relief valve of the fuel pump 203. For example, when the current fuel supply pressure of the engine 201 is less than the minimum value of the preset fuel supply pressure range, the pressure value corresponding to the electronic relief valve may be increased to the target pressure value, thereby increasing the fuel supply pressure of the fuel pump 203 to the target pressure; when the current oil supply pressure of the engine 201 is greater than the maximum value of the preset oil supply pressure range, the pressure value corresponding to the electronic pressure relief valve may be reduced to the target pressure value, thereby reducing the oil supply pressure of the fuel pump 203 to the target pressure, and thus ensuring normal operation of the engine 201.
The control system of the engine oil supply pressure can control the fuel pump to provide different oil supply pressures for the engine by combining the operation working condition of the engine, and can also adjust the oil supply pressure of the engine in real time in the operation process of the engine so as to realize the normal operation of the engine.
