[0002] The vehicles equipped with diesel engines on the market are prone to overload failure when the diesel engine burns. That is, the DPF equipped for post-processing will adsorb the particulate matter discharged by the engine combustion.

However, for various reasons, the engine cannot actively regenerate or the active regeneration process is frequently interrupted. When the mass of the adsorbed particulate matter reaches a certain calibratable value, the engine cannot actively regenerate. At this time, the engine will report an overload failure, and the engine torque output will be limited accordingly. However, the fault only includes overload and torque limiting failure, and no other faults are reported.

[0034] The example embodiments will be described in detail herein with reference to the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following example embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] The block diagrams shown in the drawings are only functional entities, and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0036] The flow chart shown in the drawing is only an exemplary illustration, not necessarily including all the contents and operations / steps, and not necessarily executed in the order described. For example, some operations / steps can be further decomposed, and some operations / steps can be combined or partially combined, so the actual execution order can be changed according to the actual situation.

[0037] "Multiple" mentioned in the present application refers to two or more than two. "And / or" describes the association relationship of associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents that the associated objects before and after are in an "or" relationship.

[0038] First of all, it needs to be explained that there are four stages in the diesel engine combustion process: 1. Ignition delay period, the ignition delay period refers to the period from the start of fuel injection to ignition, during which a series of physical and chemical preparation processes such as atomization, heating and evaporation, diffusion, mixing and initial oxidation are carried out. It is an important parameter of the combustion process, which has a direct impact on the characteristics of the combustion heat release process; 2. Rapid combustion stage, the fuel injected into the combustion chamber during the ignition delay period is almost simultaneously combusted during the rapid combustion period, so the heat release rate is very high, and the pressure rises particularly quickly; 3. Main combustion stage, the combustion of fuel in the slow combustion period depends on the mixing speed. Therefore, strengthening the air disturbance in the combustion chamber and accelerating the mixing of air and fuel play an important role in ensuring that the fuel burns rapidly and completely near the top dead center; 4. After-combustion stage, the mixing and combustion time of the unit is very short, so that some fuel cannot be burned in time near the top dead center, and the heat released in the late expansion stroke cannot be fully utilized, so fuel combustion in the after-combustion period should be avoided as much as possible.

[0039] For vehicles equipped with diesel particulate filters and diesel engines, an overload fault often occurs, that is, the diesel particulate filter equipped in the aftertreatment will adsorb the particulate matter burned and discharged by the engine, and when the weight of the particulate matter adsorbed thereon reaches a certain value, the engine will automatically perform active regeneration. However, due to environmental reasons, the engine cannot always perform active regeneration or the regeneration process is frequently interrupted. As a result, when the mass of the particulate matter adsorbed on the diesel particulate filter is overloaded, the engine cannot perform active regeneration, at which time the engine will report an overload fault and limit the torque output of the engine. However, since the engine only reports an overload and torque limiting fault, the cause of the fault cannot be clearly determined, which causes great distress to maintenance personnel.

[0040] In order to solve the above problems, the embodiments of the present application respectively provide a diesel engine combustion detection method, a diesel engine combustion detection device, an electronic device, a computer readable storage medium and a computer program product.

[0041] AsFigure 1 shown, Figure 1 is a flow chart of a diesel engine combustion detection method according to an example embodiment of the present application, which comprises steps S110 to S130, which are described in detail as follows:

[0042] In step S110, raw emission particulate data generated by engine combustion is acquired by a dust sensor.

[0043] First of all, it should be noted that in this embodiment, the dust sensor can be arranged at a position in front of a Diesel Particulate Filter (DPF) used in conjunction with a diesel engine, for acquiring raw emission particulate data of the diesel engine.

[0044] In step S110, raw emission particulate data generated by engine combustion is acquired by a dust sensor.

[0045] In step S120, the raw emission particulate data is compared with preset diesel engine emission particulate model values to obtain a corresponding comparison result.

[0046] First of all, it should be noted that in this embodiment, raw emission particulate data of an engine of a vehicle is acquired at different environmental temperatures and at preset altitudes, at different torques and speeds of the engine, and the temperature, altitude and other environmental variables of the vehicle, the speed and torque and other vehicle state variables of the vehicle are adjusted to obtain a plurality of actual emission particulate data of the vehicle at different variable factors, so as to obtain a diesel engine emission particulate model of the vehicle by comprehensively analyzing the plurality of actual emission particulate data of the vehicle at different variable factors.

[0047] Specifically, in step S120, raw emission particulate data generated by engine combustion is acquired by a dust sensor of the vehicle, and vehicle characteristic data of the vehicle is acquired, wherein the vehicle characteristic data includes the current torque of the vehicle, the real-time speed of the vehicle, and environmental information of the vehicle, wherein the environmental information includes the altitude of the vehicle, the temperature of the environment of the vehicle, and the comparison between the acquired vehicle characteristic data and the raw emission particulate data generated by engine combustion and the model values in the preset diesel engine emission particulate model is performed to obtain a comparison result between the raw emission particulate data generated by engine combustion of the vehicle and the model values in the preset diesel engine emission particulate model.

[0048] Step S130, determining the detection result of the emission of the diesel engine combustion according to the comparison result.

[0049] Specifically, the emission result of the diesel engine combustion of the vehicle is determined according to the comparison result of the original emission particulate data generated by the engine combustion of the vehicle and the model value in the preset diesel engine emission particulate model. For example, if the difference between the original emission particulate data generated by the engine combustion of the vehicle and the model value in the preset diesel engine emission particulate model is within the preset numerical range, it is determined that the diesel engine combustion is normal. If the original emission particulate data generated by the engine combustion of the vehicle exceeds the model value in the preset diesel engine emission particulate model, and the exceeding value is greater than the preset numerical value, it is determined that the diesel engine combustion of the vehicle is abnormal, and the driver is prompted of the current driving risk, and the specific problem is prompted to the maintenance personnel.

[0050] In the embodiment, the original emission particulate data generated by the engine combustion of the vehicle engine is acquired, and the acquired original emission particulate data is compared with the preset diesel engine emission particulate model to determine the detection result of the emission of the engine combustion according to the obtained comparison result, so as to further determine the fault reason of the engine. The damage of the engine caused by the emission particulate of the engine combustion is avoided, and the driving safety and user experience are improved. Further, based on the above embodiment, please refer to Figure 2 In one of the embodiments provided in the application, before the original emission particulate data is compared with the preset diesel engine emission particulate model to obtain the corresponding comparison result, the diesel engine combustion detection method further includes steps S210 to S230, which are described in detail as follows:

[0051] Step S210, acquiring original emission particulate data generated by engine combustion under different working condition data;

[0052] Step S220, correcting the original emission particulate data based on the corresponding vehicle working condition data of the engine to obtain respective corresponding emission particulate data model values of the engine under different working condition data;

[0053] Step S230, aggregating the respective corresponding emission particulate data model values of the engine under different working condition data to obtain the preset diesel engine emission particulate model.

[0054] Specifically, the original emission particulate data generated by the diesel engine combustion under different working condition data is collected. For example, the vehicle is in different working conditions, wherein the working condition data includes the vehicle speed, the torque of the vehicle, the altitude of the vehicle, the temperature of the current environment, and the humidity of the current environment. In this embodiment, the original emission particulate data generated by the diesel engine combustion of the test vehicle under different working conditions is collected, and the collected original emission particulate data generated by the diesel engine combustion is corrected through the current working condition data of the vehicle to obtain the corrected emission particulate data model value corresponding to each working condition data of the engine. Then, the corrected emission particulate data model value of the diesel engine under different working conditions and different altitudes is aggregated to obtain the emission particulate model of the diesel engine.

[0055] In this embodiment, the original emission particulate data generated by the diesel engine combustion under different working conditions and different altitudes is collected in advance, and the collected original emission particulate data is corrected based on environmental factors. In this way, the emission particulate data model of the diesel engine under different working conditions is aggregated based on the corrected model value. In this way, not only the accuracy of the data in the established emission particulate data model is improved, but also the basis for finding the fault cause of the vehicle with the combustion emission particulate overload fault is provided.

[0056] Further, based on the above embodiment, in one of the example embodiments provided in the present application, the working condition data includes the torque of the engine. The specific implementation process of collecting the original emission particulate data generated by the engine combustion under different working condition data can further include the following steps, which are described in detail as follows:

[0057] The original emission particulate data generated by the engine combustion under different torques of the engine is collected.

[0058] Specifically, as described in the above embodiment, in the process of pre-establishing the emission particulate model generated by the diesel engine combustion, it is also necessary to test the original emission particulate data generated by the diesel engine combustion under different torques of the diesel engine.

[0059] Further, based on the above embodiment, in one of the example embodiments provided in the present application, the working condition data further includes the current environmental temperature of the engine and the speed of the engine; the specific implementation process of collecting the original emission particulate data generated by the engine combustion under different working condition data can further include the following steps, which are described in detail as follows:

[0060] Collecting raw emission particulate data generated by the engine under different temperature environments and different engine rotating speeds.

[0061] Specifically, in the embodiment, the raw emission particulate data generated by the diesel engine under different working conditions, such as under different ambient temperatures, is collected by setting the engine rotating speed of the vehicle as a variable. For example, when the ambient temperature is 25 degrees and the engine rotating speed is 1800 rpm, the raw emission particulate data generated by the diesel engine is tested and collected, and the raw emission particulate data is corrected according to the current ambient temperature and altitude to record the corrected emission particulate data. In the embodiment, the corrected emission particulate data of the engine under different ambient temperatures and different engine rotating speeds is tested and recorded.

[0062] Further, based on the above embodiment, in one of the example embodiments provided in the application, the working condition data further includes the altitude, the current ambient temperature of the engine and the rotating speed of the engine; the specific implementation process of collecting the raw emission particulate data generated by the engine under different working conditions can further include the following steps, which are described in detail as follows:

[0063] Collecting raw emission particulate data generated by the engine under different altitudes, different temperature environments and different engine rotating speeds.

[0064] Specifically, in the embodiment, the raw emission particulate data generated by the diesel engine under different working conditions, such as under different ambient temperatures, is collected by setting the engine rotating speed of the vehicle as a variable. For example, when the ambient temperature is 25 degrees and the engine rotating speed is 1800 rpm, the raw emission particulate data generated by the diesel engine is tested and collected, and the raw emission particulate data is corrected according to the current ambient temperature and altitude to record the corrected emission particulate data. In the embodiment, the corrected emission particulate data of the engine under different ambient temperatures and different engine rotating speeds is tested and recorded.

[0065] Further, based on the above embodiment, please refer to Figure 3 In one of the example embodiments provided in the application, the implementation process of correcting the raw emission particulate data based on the working condition data of the vehicle corresponding to the engine to obtain the emission particulate data model value corresponding to each working condition data of the engine can further include steps S310 and S320, which are described in detail as follows:

[0066] Step S310, calculating the emission data compensation value corresponding to the altitude, ambient temperature and engine rotating speed of the vehicle;

[0067] Step S320, correcting the original emission particulate data based on the emission data compensation value to obtain the respective corresponding emission particulate data model value of the engine under different working condition data.

[0068] Specifically, in the embodiment, the original emission particulate generated in the combustion process of the diesel engine is collected, and the environmental information of the vehicle currently located is collected, wherein the environmental information includes the current temperature of the environment, the humidity of the environment, the altitude of the vehicle, and the working condition data of the current vehicle, and the respective corresponding original emission particulate data compensation value of the current temperature of the environment, the humidity of the environment, the altitude of the vehicle, and the working condition data of the current vehicle in the environmental information is calculated, and the original emission particulate data generated by the combustion of the diesel engine is corrected based on the plurality of original emission particulate data compensation values, so as to obtain the respective corresponding emission particulate data model value of the diesel engine under different working condition data and environmental information.

[0069] In the embodiment, the respective corresponding emission data compensation value of the altitude of the vehicle, the environmental temperature, and the engine speed is calculated, and the original emission particulate data is corrected based on the emission data compensation value to obtain the respective corresponding emission particulate data model value of the engine under different working condition data. In this way, not only the accuracy of the obtained emission particulate data model value is ensured, but also the accuracy of the fault test of the diesel engine is improved.

[0070] Further, based on the above embodiment, please refer to Figure 4 In one of the example embodiments provided in the application, the specific implementation process of determining the detection result of the emission of the diesel engine combustion according to the comparison result can further include steps S410 and S420, which are described in detail as follows:

[0071] Step S410, if the comparison result represents that the original emission particulate data is greater than the first preset threshold in the preset diesel engine emission particulate model, the engine combustion deterioration fault is sent to the instrument, and the corresponding fault information is recorded;

[0072] Step S420, if the comparison result represents that the original emission particulate data is less than the second preset threshold in the preset diesel engine emission particulate model, no fault information is sent to the instrument.

[0073] Specifically, in the embodiment, the original emission particulate matter generated by the diesel engine combustion is monitored in real time through the dust sensor (PM sensor) installed in front of the diesel engine, and the monitored original emission particulate matter data is compared with the pre-constructed diesel engine emission particulate matter model, and the current situation of the diesel engine is determined according to the comparison result.

[0074] For example, if the comparison result indicates that the original emission particulate matter data is greater than the first preset threshold in the preset diesel engine emission particulate matter model, the engine combustion deterioration fault is sent to the instrument, and the corresponding fault information is recorded; if the comparison result indicates that the original emission particulate matter data is less than the second preset threshold in the preset diesel engine emission particulate matter model, no fault information is sent to the instrument. Thus, by setting different fault thresholds, the combustion condition of the engine can be monitored in real time, so as to avoid the occurrence of engine overload fault.

[0075] In the embodiment, on the one hand, the combustion condition of the vehicle diesel engine is monitored in real time, and the engine combustion deterioration fault is found in time, so as to avoid the occurrence of engine overload fault; on the other hand, the fault reason of the vehicle which has occurred overload fault can be found in time, so as to improve the efficiency of solving the vehicle overload fault.
