[0005] As an optional implementation, the control method further includes: acquiring the real-time power of the engine; determining whether the real-time power of the engine is greater than or equal to a preset engine power; if the real-time power of the engine is greater than or equal to the preset engine power, controlling the pump body to stop injecting the diesel detergent.

[0006] As an optional implementation, the control method further includes: if the real-time engine power is less than the preset engine power, then controlling the pump to continuously inject the diesel detergent until the real-time engine power is greater than the preset engine power.

[0009] As an optional implementation, the control method further includes: determining the number of times the diesel detergent is injected; if the number of times the diesel detergent is injected reaches a preset number, and the real-time engine power is still less than the preset engine power, controlling the pump to stop injecting the diesel detergent.

[0010] As an optional implementation, the control method further includes: adding diesel detergent into the tank if the number of times the diesel detergent is sprayed reaches a preset number; or controlling the diesel detergent device to output an alarm signal.

[0011] According to another aspect of the embodiments of this application, a control system for a diesel cleaning agent is also provided, comprising: a diesel injection quantity acquisition module for acquiring engine power and diesel injection quantity; a power reduction rate determination module for determining an engine power reduction rate based on the engine power; an injection quantity reduction rate determination module for determining a diesel injection quantity reduction rate based on the diesel injection quantity; a judgment module for determining whether the engine power reduction rate is greater than a preset power reduction rate and whether the diesel injection quantity reduction rate is greater than a preset injection quantity reduction rate; and a pump control module for controlling the pump to open and inject the diesel cleaning agent when the engine power reduction rate is greater than the preset power reduction rate and the diesel injection quantity reduction rate is greater than the preset injection quantity reduction rate.

[0012] According to another aspect of the embodiments of this application, an electronic device is provided, including a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus, the memory is used to store a computer program, and the processor is used to execute the control method steps of the diesel cleaning agent by running the computer program stored in the memory.

[0019] 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.

[0020] 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.

[0021] Currently, high-pressure direct injection natural gas engines use dual nozzles, one for diesel and one for natural gas. Because diesel fuel has a short operating time and low pressure, it is easy for the nozzles to accumulate carbon, resulting in a decrease in engine power and affecting the user experience.

[0022] like Figure 1 As shown in the figure, this application provides a control method for a diesel cleaning agent, applied to a diesel cleaning agent device. The diesel cleaning agent device includes a tank for holding the diesel cleaning agent and a pump for controlling the diesel cleaning agent; the control method includes:

[0023] S1 obtains engine power and diesel injection quantity;

[0024] S2 determines the engine power reduction rate based on engine power;

[0025] S3 determines the diesel injection quantity reduction rate based on the diesel injection quantity;

[0026] S4 determines whether the engine power reduction rate is greater than the preset power reduction rate and whether the diesel injection quantity reduction rate is greater than the preset injection quantity reduction rate;

[0027] S5 If the engine power reduction rate is greater than the preset power reduction rate and the diesel injection quantity reduction rate is greater than the preset injection quantity reduction rate, control the pump body to open and inject the diesel detergent.

[0028] Diesel cleaner: A fuel system cleaner and protectant soluble in diesel fuel, with an affinity for metal surfaces and carbon deposits, featuring a hydrocarbon polymer tail and a polar head.

[0029] Specifically, firstly, due to the short operating time and low fuel line pressure of diesel fuel, carbon deposits easily accumulate in the injectors, leading to a decrease in engine power. Therefore, the decrease in engine power can serve as an important indicator for assessing carbon deposits in the diesel injection system. Simultaneously, carbon deposits in the diesel injection system also directly result in a decrease in diesel injection quantity; therefore, a decrease in diesel injection quantity is also a crucial indicator for assessing carbon deposits in the diesel injection system. Therefore, in this application, the engine power and diesel injection quantity are first obtained, and the engine power reduction rate and the diesel injection quantity reduction rate are determined based on these parameters. It should be understood that the engine power reduction rate described in this application can be the rated... The ratio of the difference between the engine power and the current engine power to the rated power is used. Similarly, the rate of decrease in diesel injection quantity can be the ratio of the difference between the standard diesel injection quantity and the current diesel injection quantity to the standard diesel injection quantity. It is then determined whether the rate of decrease in engine power is greater than the preset rate of decrease in power, and whether the rate of decrease in diesel injection quantity is greater than the preset rate of decrease in injection quantity. If both the rate of decrease in engine power and the rate of decrease in diesel injection quantity are greater than the preset rate of decrease in injection quantity, then it is considered that the current diesel injection nozzles are carbon-deposited and significantly affect the normal operation of the engine. In this case, the pump body is controlled to open and the diesel detergent is injected.

[0030] It should also be noted that the preset power reduction rate and the preset injection volume reduction rate mentioned in this application are set according to different engine models and different engine operating conditions. At the same time, technicians can also select them according to the actual situation. For example, the preset power reduction rate and the preset injection volume reduction rate can be set between 15% and 30%. However, if technicians believe that carbon deposits should be removed when the carbon deposits on the diesel fuel line nozzles are relatively small in order to extend the service life of the engine, the preset power reduction rate and the preset injection volume reduction rate can be less than 15%. This application does not limit this.

[0031] The above control methods solve the technical problems in existing technologies, such as short diesel fuel operating time, low fuel line pressure, easy carbon buildup in nozzles, resulting in reduced engine power and affecting user experience. Furthermore, the diesel detergent does not need to be added directly to the diesel fuel; it is only used when necessary, saving users operating costs and simplifying maintenance.

[0032] As an optional implementation, the control method further includes: acquiring the real-time power of the engine; determining whether the real-time power of the engine is greater than or equal to a preset engine power; if the real-time power of the engine is greater than or equal to the preset engine power, controlling the pump body to stop injecting the diesel detergent.

[0033] Specifically, it can be understood that the engine power can be acquired in real time and the magnitude of the real-time power can be judged in real time. When the real-time engine power is greater than or equal to the preset engine power, it can be considered that the carbon deposits on the diesel fuel injector have been eliminated or are in a state that no longer affects diesel injection. At this time, the pump body is controlled to stop injecting the diesel detergent. This setting method can greatly save diesel detergent and greatly improve the intelligence level of diesel detergent injection.

[0034] As an optional implementation, the control method further includes: if the real-time engine power is less than the preset engine power, then controlling the pump to continuously inject the diesel detergent until the real-time engine power is greater than the preset engine power.

[0035] Specifically, if the real-time engine power is always less than the preset engine power after the pump body injects the diesel detergent, then the pump body can be controlled to continuously inject the diesel detergent until the real-time engine power is greater than the preset engine power, so as to ensure the elimination of carbon deposits in the diesel injection circuit to a large extent.

[0036] As an optional implementation, controlling the pump body to open and spray the diesel detergent includes: controlling the pump body to spray the diesel detergent once or multiple times; controlling the pump body to spray the diesel detergent once includes: stopping the spraying after spraying the diesel detergent for a preset time.

[0037] For example, the pump body can be configured to spray multiple times, wherein each spray lasts for a preset duration and stops spraying after the preset duration. The specific preset duration can be selected according to the actual situation. For example, each spray can make the pump body spray continuously for 10 hours. If there are multiple sprays, there can be a 30-minute pause between each spray. This application does not limit this.

[0038] As an optional implementation, controlling the pump body to continuously inject the diesel detergent includes: if the real-time engine power is less than the preset engine power, controlling the pump body to inject the diesel detergent multiple times until the real-time engine power is greater than the preset engine power.

[0039] As an optional implementation, the control method further includes: determining the number of times the diesel detergent is injected; if the number of times the diesel detergent is injected reaches a preset number, and the real-time engine power is still less than the preset engine power, controlling the pump to stop injecting the diesel detergent.

[0040] Specifically, if the number of injections exceeds the predetermined number and the power still cannot be restored, it can be assumed that there is a fault in the engine or a lack of diesel detergent, causing the pump to only perform the injection action without spraying out the diesel detergent. Therefore, at this time, the pump stops spraying the diesel detergent.

[0041] As an optional implementation, the control method further includes: adding diesel detergent into the tank if the number of times the diesel detergent is sprayed reaches a preset number; or controlling the diesel detergent device to output an alarm signal.

[0042] According to another aspect of the embodiments of this application, a control system for a diesel cleaning agent is also provided. A diesel injection quantity acquisition module is used to acquire engine power and diesel injection quantity;

[0043] A power reduction rate determination module is used to determine the engine power reduction rate based on the engine power.

[0045] The judgment module is used to determine whether the engine power reduction rate is greater than the preset power reduction rate and whether the diesel injection quantity reduction rate is greater than the preset injection quantity reduction rate.

[0046] The pump control module is used to control the pump to open and inject the diesel detergent when the engine power reduction rate is greater than the preset power reduction rate and the diesel injection quantity reduction rate is greater than the preset injection quantity reduction rate.
