When the engine is cold started, in order to enable the temperature of the engine oil of the oil pan to rise rapidly, the heating time is shortened, a double-layer oil pan structure is often adopted, and the structure has the advantages that in the heating process, as the stored engine oil of the inner oil pan is less, only a small part of the oil of the inner oil pan can participate in circulation, the temperature rise speed of the engine oil is accelerated, and compared with the whole heating engine oil, the heating time is shortened greatly.
In the related double-layer oil pan scheme, a temperature control valve is arranged between the inner oil pan and the outer oil pan. When the engine is cold started, the temperature control valve is closed, and at the moment, only a small amount of oil in the inner oil pan participates in the circulation of the engine lubricating system, so that the temperature of the engine oil rises faster, and the hot car time is shortened.

The embodiment of the application provides a vehicle, which comprises a vehicle frame and an engine, wherein an engine bin is arranged in the vehicle frame, and the engine is arranged in the engine bin. When the engine oil consumption is too large or oil leakage exists in the engine, the engine oil in the engine oil pan can be gradually reduced, the engine cannot suck the engine oil, an engine oil pressure alarm is generated at the moment, and the engine is damaged when the vehicle continues to run. Therefore, there is a need for an engine that can pump oil from the bottom of the engine oil casing into the lubrication system of the engine in the event of an oil pressure warning, i.e. when the engine is not drawing oil.
To solve the above technical problem, an embodiment of the present application provides an engine, and by way of example, referring to fig. 1, the engine includes an outer oil sump 1, an inner oil sump 2, a first oil passage, and a second oil passage, where the inner oil sump 2 is disposed inside the outer oil sump 1. The first oil passage comprises a valve 3 arranged on the inner oil bin 2, and when the valve 3 is opened, the inner oil bin 2 is communicated with the outer oil bin 1; the second oil channel comprises an oil suction pipeline and an oil pump 4 arranged on the oil suction pipeline, wherein one end of the oil suction pipeline is close to the bottom of the outer oil bin 1; the other end is communicated to the upper part of the inner oil sump 2, the inner oil sump 2 is communicated with the outer oil sump 1, and the oil pump 4 is used for pumping the oil in the outer oil sump 1 into the inner oil sump 2.
Specifically, when the valve 3 is closed, two independent cavities are arranged between the inner oil sump 2 and the outer oil sump 1, the inner cavity of the outer oil sump 1 is positioned at the outer side of the inner oil sump 2, and an oil pump arranged in the engine firstly pumps the engine oil in the inner oil sump 2 to various parts of the engine for lubrication and heating, such as an engine inner crankshaft 8, so that the heating time is shortened greatly compared with the whole heating of the engine oil. In addition, after the temperature of the engine oil in the inner oil bin 2 reaches a certain temperature threshold value, the control valve 3 is opened, so that the inner oil bin 2 and the outer oil bin 1 are in a communication state, namely, a first oil channel is formed between the inner oil bin 2 and the outer oil bin 1 by opening the valve 3, and at the moment, the engine oil in the inner oil bin 2 and the engine oil in the outer oil bin 1 are completely participated in circulation, so that the quantity of the engine oil participated in circulation is ensured to meet the requirement. Further, when the engine oil leaks or part of the engine oil is consumed in the running process of the vehicle, the level of the engine oil can be reduced, the engine oil can not be sucked by the engine oil strainer 7 arranged in the inner oil sump 2, and the engine oil pressure can be alarmed, at the moment, the engine oil in the outer oil sump 1 can be pumped into the inner oil sump 2 through the oil pump 4 in the oil suction pipeline by the design of the second oil channel, so that the amount of the engine oil in the inner oil sump 2 can be increased, namely the level of the engine oil in the inner oil sump 2 is increased, the engine oil can be sucked into the engine by the engine oil strainer 7, and the normal running of the vehicle to a maintenance shop for inspection and maintenance can be ensured.
Here, after the vehicle is started normally, the valve 3 is in an open state, the oil pump 4 is in a closed state, and at this time, the inner oil sump 2 and the outer oil sump 1 are in a communicating state, that is, engine oil in the inner oil sump and the outer oil sump all participate in the engine lubrication system circulation. When the oil level drops to a position below the oil suction disc of the oil strainer 7, the oil pressure alarms, and at the moment, the valve 3 is in a closed state, and the oil pump 4 is in an open state until most or all of the engine oil in the outer oil sump 1 is pumped into the inner oil sump 2.
In some embodiments, referring to fig. 1, one end of the oil suction line is connected to the bottom end of the outer sump 1. Thus, the engine oil in the outer oil bin 1 can be pumped into the inner oil bin to the greatest extent.
Further, referring to fig. 1, the oil suction line includes a first oil pipe 5 and a second oil pipe 6.
One end of the first oil pipe 5 is connected with an oil inlet of the oil pump 4, and the other end of the first oil pipe 5 extends into the bottom of the outer oil bin 1; one end of the second oil pipe 6 is connected with the oil outlet of the oil pump 4, and the other end of the second oil pipe 6 is positioned above the inner oil bin 2. By such design, a complete second oil passage can be formed, specifically, after the valve 3 is closed, the oil pump 4 is opened, and the engine oil at the bottom of the outer oil bin 1 is pressurized by the first oil pipe 5 through the oil pump 4 and then is conveyed into the inner oil bin 2 by the second oil pipe 6. Thereby, the oil level in the inner oil sump 2 is ensured by the second oil passage, thereby ensuring that the oil strainer 7 can suck the oil.
In some embodiments, referring to fig. 1, the valve 3 is an electronically controlled valve. Here, the valve 3 may also be a temperature control valve, and compared with a temperature control valve, the electric control valve can be matched with different circuits to realize expected control, and the control precision and flexibility of the valve can be ensured, so that the valve 3 of the application adopts the electric control valve.
Referring to fig. 1, the volume of the inner sump 2 is greater than or equal to the volume of the outer sump 1. Here, when the valve 3 is in a closed state and the oil pump 4 is in an open state, the volume of the inner oil sump 2 is greater than or equal to the volume of the outer oil sump 1, so that the oil in the outer oil sump 1 can be prevented from overflowing out of the inner oil sump 2 after being pumped into the inner oil sump 2.
Here, it is preferable to use a design in which the volume of the inner oil sump 2 is equal to the volume of the outer oil sump 1, and it should be noted that the equality is not a numerical equality, but a functionally approximate equality, that is, the volume of the inner oil sump 2 is approximately equal to the volume of the outer oil sump 1, so that the oil level of the inner oil sump 2 can be maximized when the oil in the outer oil sump 1 is prevented from overflowing after the oil in the outer oil sump 1 is completely pumped into the inner oil sump 2, as compared with a design in which the volume of the inner oil sump 2 is greater than the volume of the outer oil sump 1, thereby further ensuring that the vehicle can continue to travel a longer distance when an engine oil lamp alarm occurs.
In some embodiments, referring to fig. 1, the valve 3 is disposed near the bottom of the inner sump 2. Here, first, the valve 3 is set, so that the outer oil sump 1 and the inner oil sump 2 which are independent of each other originally can be connected together through opening of the valve, thereby enabling oil convection between the outer oil sump 1 and the inner oil sump 2, and compared with the design that the valve 3 is close to the bottom of the inner oil sump 2, the design that the valve 3 is far away from the bottom of the inner oil sump 2, when the oil in the inner oil sump 2 is at a lower liquid level, the oil convection between the oil in the inner oil sump 2 and the oil convection between the outer oil sump 1 can still be ensured when the valve 3 is opened.
In some embodiments, referring to fig. 1 and 2, the engine includes an oil amount detection module for detecting oil amount information. When the engine is excessively consumed or leaked, the oil strainer 7 cannot suck the engine oil, and the oil quantity detection module can detect the oil quantity information at the moment so as to trigger an engine oil pressure alarm to feed back the oil quantity information to a driver, so that the driver is prompted to perform corresponding operations, such as stopping the vehicle, or closing the valve 3 and starting the oil pump 4, and the oil level of the inner oil bin 2 is raised at the moment, the engine can suck the engine oil, and the vehicle can continue to run to a repair shop for inspection and maintenance.
The oil amount information here may be oil pressure information, liquid level information, or the like.
Further, referring to fig. 1 and 2, the engine further includes a control module, where the control module is configured to detect the oil amount information by the oil amount detection module; when the oil amount information reaches a first threshold, executing a command, the command comprising: the first oil passage is closed and the second oil passage is opened. Specifically, the control module controls the valve 3 to be closed, controls the oil pump 4 to be opened, i.e. closes the first oil passage and opens the second oil passage when the oil pressure or the oil level reaches a first threshold value according to the oil amount information detected by the oil amount detection module, such as the oil pressure information, the oil level information, etc. The control module is introduced, so that the action response of the engine oil circulation in the engine is intelligent and efficient.

Here, the preset time specifically refers to a time period during which the oil pump 4 is operated, and the preset value of the time period is not specifically limited, and in a state in which the valve 3 is closed and the oil pump 4 is opened, the oil pump operation time period may ensure that all the engine oil in the outer oil sump 1 is pumped into the inner oil sump 2.
In some embodiments, referring to fig. 1, 5, the step of S4 further comprises:
s41, detecting oil quantity information by an oil quantity detection module;
s42, executing a command when the oil quantity information reaches a second threshold value;
s43, closing the second oil channel.
Thus, the control efficiency and quality of the control logic of the control method can be improved.
Continuing with reference to fig. 2 and 7, the command further includes: an alert is sent. Here, the specific form of sending the alarm is not limited, and may be, for example, a light alarm, an acoustic alarm, or the like. Because the lamplight alarm has strong reliability and is simple and easy to implement, the lamplight alarm is preferably selected. Specifically, for example, when the oil amount information reaches a first threshold, the engine oil lamp is turned on as a form of sending an alarm; when the oil quantity information reaches a second threshold, the engine oil lamp is extinguished as a form of sending an alarm. The design of sending the alarm is simple and easy to implement, and the reliability is high.
In some embodiments, referring to fig. 2 and 3, the oil amount information is oil pressure information. The oil pressure information is detected, oil quantity information of oil circulation in the engine can be accurately reflected, for example, when the oil pressure is low, the oil quantity of the engine lubricating system can be fed back to be reduced, the service life of the engine is influenced, and a driver is prompted to make timely treatment.
In some embodiments, referring to fig. 1 and 6, before step S1, further comprising:
s01, detecting oil quantity information by an oil quantity detection module;
s02, the oil quantity information reaches a second threshold value, and a command is executed;
s03, opening the first oil channel and closing the second oil channel.
Wherein the level of the second threshold is higher than the level of the first threshold. Specifically, when the oil quantity information reaches the second threshold value, the first oil channel is opened, the second oil channel is closed, the oil pump 4 is in a closed state, the valve 3 is in an open state, the inner oil bin 1 and the outer oil bin 2 of the engine are in a communicating state, at this time, the oil quantity can normally ensure the oil circulation quantity of the lubricating system of the engine, and when the oil quantity is greatly reduced, the liquid level is in a lower position, the oil suction port of the oil strainer 7 of the engine is positioned above the liquid level, namely, when the oil suction port of the oil strainer 7 cannot suck the engine oil, at this time, the oil quantity information reaches the first threshold value, the first oil channel is closed, the second oil channel is opened, so that the oil at the bottom of the outer oil bin 1 is pumped into the inner oil bin 2, the liquid level in the inner oil bin 2 is raised, and the normal oil supply quantity of the engine is provided.
Finally, referring to fig. 1 and 7, it should be fully and additionally described that, when the engine is excessively consumed or oil leaks from the engine, the amount of oil in the engine oil sump is greatly reduced, and the level of the oil in the engine oil sump is inevitably lowered to a position below the oil suction disc of the oil strainer 7 in the engine maintenance period, so that the oil is not sucked by the oil strainer, and the corresponding engine oil pressure is alarmed, and at this time, the vehicle is not allowed to continue running, otherwise the engine is damaged. The application implements the following strategy in this case: when the engine oil lamp alarms, the second oil channel can be opened, namely the valve 3 is closed, the oil pump 4 is opened, the oil pump 4 arranged in the second oil channel sucks engine oil in the outer oil bin 1 to be supplemented into the inner oil bin 2, the engine oil liquid level in the inner oil bin 2 is improved, the engine oil strainer 7 is guaranteed to suck engine oil, after the oil pump 4 is opened for a certain preset time, the engine oil in the outer oil bin 1 is completely pumped into the inner oil bin 2, at the moment, the engine oil lamp is extinguished, and a driver is informed of starting to repair shop to check and maintain, and direct anchoring of the vehicle is avoided. In addition, if the valve 3 is closed and the oil pump 4 is turned on for a predetermined time, the oil lamp is not turned off, which means that there is no amount of oil in the engine that can be guaranteed to participate in the circulation, and other trouble problems should exist, such as the occurrence of oil leakage may be particularly serious, or the oil pump 4 may not be operated normally, or the oil circulation system in the engine may be failed, and at this time, the trailer is required to be checked and maintained in a repair shop.
