[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0022] like Figure 1 As shown in the illustration, this application provides an engine oil control system, including: an oil solid additive replenishment tank 1, forming an oil receiving cavity for containing an oil mixture including solid additives; an oil replenishment pipe 2, one end connected to the oil solid additive replenishment tank 1 and the other end connected to the oil pan 4; and a control valve 3, disposed in the oil replenishment pipe 2, for controlling the flow of oil from the oil solid additive replenishment tank 1 into the oil replenishment pipe 2.
[0023] Specifically, an oil solid additive replenishment tank 1 is provided, which is connected to the oil pan 4 through an oil replenishment pipe 2. The oil replenishment pipe 2 is equipped with a control valve 3, which can control the flow of the oil mixture containing solid additives in the oil solid additive replenishment tank 1 into the oil pan 4. By adding a simple device, the lubrication capacity of the engine oil is improved, the engine friction work is reduced, the oil consumption is reduced, and to a certain extent, the occurrence of major failures such as engine cylinder scoring and bearing failure is avoided.
[0024] Engine oil solid additives are substances that reduce friction and wear by relying on their special molecular structure and the formation of a special protective film at high temperatures. Commonly used additives include molybdenum disulfide, graphene, and cermets. These substances are dissolved in engine lubricating oil through structural modification, which further reduces friction and improves wear resistance.
[0025] This application does not limit the specific composition and proportion of solid additives in the engine oil solid additive replenishment tank 1. The engine oil solid additive replenishment tank 1 can directly contain liquid mixtures with a solid additive ratio that can be used directly, or it can contain engine oil mixtures with a high solid additive content. When the control valve 3 is opened, the engine oil mixtures with a high solid additive content can enter the oil pan 4 for mixing, and the proportion of solid additives after mixing reaches a suitable ratio.
[0026] As an optional implementation, the control valve 3 is connected to the electronic control unit 5; the electronic control unit 5 is configured to control the control valve 3 to open when the fuel consumption is greater than the preset fuel consumption.
[0027] Specifically, if the fuel consumption is greater than the preset fuel consumption at the current speed and torque, it can be determined that the friction work has increased, and the electronic control unit 5 controls the control valve 3 to open.
[0028] As an optional implementation, an oil level sensor 6 is also included, disposed in the oil pan 4. The oil level sensor 6 is also connected to the electronic control unit 5. The electronic control unit 5 is further configured to control the opening duration of the control valve 3 based on the oil level obtained by the oil level sensor 6.
[0029] After the electronic control unit 5 controls the opening of the switch valve based on the increase in friction work, it can determine the filling volume of the oil solid additive mixture according to the oil level and the required oil volume, and then control the opening time of the control valve 3.
[0030] It should be noted that this application does not limit the specific model of the liquid level sensor, which is connected to the CAN bus of the electronic control unit 5.
[0031] As an optional implementation, the electronic control unit 5 is communicatively connected to the instrument display module 7, and the electronic control unit 5 is further configured to control the instrument display module 7 to output a signal to characterize excessive fuel consumption if the fuel consumption is still greater than the preset fuel consumption within a preset time after the control valve 3 is closed.
[0032] As an optional implementation, the electronic control unit 5 is communicatively connected to the instrument display module 7, and the electronic control unit 5 is further configured to control the instrument display module 7 to display a signal indicating an abnormal oil level when the oil level obtained by the oil level sensor 6 does not meet the preset oil level threshold.
[0033] As an optional implementation, an oil quality sensor 8 is also included, disposed in the oil pan 4.
[0034] As an optional implementation, the oil quality sensor 8 is connected to the electronic control unit 5.
[0035] As an optional implementation, the electronic control unit 5 is configured to control the display module to output a signal to characterize the abnormal oil quality when the oil quality sensor 8 detects that the oil quality is lower than a preset quality.
[0036] It should be noted that this application does not limit the specific selection of the above sensors, and the specific selection can be made according to the actual situation. All the above modules are connected to the electronic control unit 5 via CAN lines.
[0037] For example, the overall control process of the engine oil control system can be as follows: the electronic control unit 5 reads the engine speed, torque, fuel consumption, oil quality, vehicle tilt angle, and oil level before the vehicle is powered on or after a preset time after parking. It is necessary to pre-calibrate the maximum and minimum oil levels at different tilt angles, the maximum fuel consumption and oil quality requirements at different speeds and torques, and the ratio of solid lubricant additives to oil.
[0038] First, check if the engine oil level is between the maximum and minimum levels. If it is above the maximum level, there may be too much oil or the oil may be diluted. Remind the driver to change or drain some of the oil. If it is below the minimum level, the engine oil level is too low. Remind the driver to add oil in time.
[0039] Next, determine if the engine oil quality meets the requirements. If the engine oil quality sensor 8 detects a normal reading, proceed to the next step. If it does not meet the requirements, it is considered deteriorated, and the driver is advised to perform timely maintenance and change the engine oil.
[0040] Finally, if the fuel consumption is greater than the preset fuel consumption at the current speed and torque, it is determined that the friction work has increased. Control valve 3 is opened, and the oil volume is calculated according to the oil level. The volume of the oil solid additive mixture is controlled according to the calibrated ratio. After the filling is completed and the preset time is run, it is determined whether the current fuel consumption is below the preset fuel consumption. If it is normal, the strategy is exited. If it is abnormal, there may be other lubrication risks. It is recommended that the driver go to the station for maintenance to check the cause of the increased engine friction work.
