The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The following describes the internal combustion engine combustion warning method, device, vehicle and storage medium of the vehicle of the embodiment of the present application with reference to the accompanying drawings. In view of the related art mentioned in the above background technology, the combustion state in the engine cylinder is controlled by monitoring a single parameter, resulting in insufficient monitoring data, relatively few monitoring dimensions, certain safety hazards, and technical problems such as slow problem processing rate and difficulty in directly hitting the problem pain points due to insufficient data mastery. The present application provides a vehicle internal combustion engine combustion warning method, in which after the vehicle is ignited, a signal generating device can be used to emit light passing through the combustion product based on the ignition signal, and a collection device can be used to collect the light to obtain a corresponding light signal, and the combustion product composition data in the combustion chamber can be obtained according to the light signal, so as to judge whether the vehicle meets the preset alarm condition based on the combustion product composition data, and when the vehicle meets the preset alarm condition, the corresponding combustion warning signal is pushed to the preset terminal, and the combustion state in the cylinder is monitored and warned in real time, so as to obtain multi-angle combustion data, and send a warning to the terminal in time, which improves the driving safety of the vehicle on the one hand, and facilitates the relevant technical personnel to perform timely maintenance on the other hand, and improves the reliability and troubleshooting processing rate of the internal combustion engine. This solves the technical problems in the related technology of controlling the combustion state in the engine cylinder by monitoring a single parameter, resulting in insufficient monitoring data, relatively few monitoring dimensions, certain safety hazards, and slow problem processing due to insufficient data control, making it difficult to directly address the pain points of the problem.

[0028] Before explaining the internal combustion engine combustion warning method of a vehicle according to an embodiment of the present application, the structure involved in the present application is first explained.

[0029] Combination Figure 1 and Figure 2 , which is a schematic diagram of the structure involved in an embodiment of the present application.

[0030] like Figure 1 and Figure 2 As shown, the structure involved in the embodiment of the present application can be composed of a cylinder 1, a piston 2, a combustion chamber 3, a wireless sensor 4, a signal amplification and collection device 5, a photoelectric signal converter 6, and a terminal 7. Taking an inline four-cylinder engine as an example, to implement this method, at least one group of collection devices that can collect optical signals and are resistant to high temperatures, namely, wireless sensors 4, is required. The optical signal generated by the flame during combustion is collected by the wireless sensor 4, and transmitted to the signal amplification and collection device 5, and then converted by the photoelectric signal converter 6 and finally transmitted to the terminal 7 for data processing and calculation to obtain the data of the combustion product composition at that location. By setting an alarm limit at the terminal 7, once the data exceeds the set range, an early warning is immediately issued, and a program is set at the same time to retain the combustion data generated during the alarm.

[0031] Specifically, Figure 3 A schematic flow chart of a combustion warning method for an internal combustion engine of a vehicle provided in an embodiment of the present application.

[0032] like Figure 3 As shown, the internal combustion engine combustion warning method of the vehicle is provided with a collection device in the combustion chamber of the internal combustion engine, and a signal generating device is provided outside the combustion chamber, wherein the method comprises the following steps:

[0033] In step S301, an ignition signal of a vehicle is collected.

[0034] In the actual implementation process, the embodiments of the present application can determine the corresponding ignition signal acquisition method according to the actual ignition type and vehicle equipment of the vehicle. For example, the working status of the ignition system can be judged by the waveform displayed on the oscilloscope: Waveform shape: a normal ignition signal should have a clear rising edge and falling edge; Frequency: based on the engine speed, calculate whether the number of ignitions per minute is consistent with expectations; check whether the voltage level of the ignition signal meets the requirements, etc.

[0035] In step S302, a signal generating device is used to emit light that passes through the combustion products based on an ignition signal, and a collecting device is used to collect the light to obtain a corresponding light signal.

[0036] As a possible implementation method, the embodiment of the present application can use a signal generating device, such as a light source, to emit light so that the emitted light passes through the combustion products, and then use a collection device, such as a high-temperature resistant sensor, to collect the light to obtain a light signal that includes the spectrum of the combustion products.

[0037] In order to allow the signal generating device to collect the spectrum of combustion products in the combustion chamber without interference, a transparent window can be provided on the side wall of the combustion chamber so that light can penetrate the transparent window, allowing the collecting device to successfully collect the optical signal.

[0038] The material of the transparent window needs to be resistant to high temperatures and pressures (such as sapphire glass) so that the light beam can penetrate, and there needs to be good sealing between the side wall of the combustion chamber and the transparent window.

[0039] Among them, the combustion products identified by optical signals may include CO2 (carbon dioxide), CO (carbon monoxide), H2O (water), NO x (nitrogen oxides) and other gases.

[0040] In step S303, the combustion product composition data in the combustion chamber is obtained according to the optical signal, and based on the combustion product composition data, it is determined whether the vehicle meets the preset alarm conditions, and when the vehicle meets the preset alarm conditions, the corresponding combustion warning signal is pushed to the preset terminal.

[0041] In some embodiments, the embodiments of the present application can select a suitable spectral analysis instrument according to actual needs, and obtain the combustion product composition in the combustion chamber by analyzing the optical signal, wherein the spectral analyzer can be Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, laser absorption spectroscopy, etc.

[0042] For example, when using infrared laser spectroscopy technology, the embodiments of the present application can use the absorption characteristics of different molecules to infrared light for gas detection. Each molecule has its own unique infrared absorption spectrum. By analyzing the wavelength position and intensity of the absorption band, the structural composition or chemical groups of the combustion products can be identified and quantitatively analyzed.

[0043] For example, hydroxyl (OH): In the infrared spectrum, the stretching vibration of hydroxyl usually appears at 3650-3200cm -1 The free hydroxyl group (unbound hydroxyl group) is between 3650 and 3610 cm -1 There is a sharp absorption peak at the hydroxyl group, while the associated hydroxyl group (such as the hydroxyl group associated within or between molecules) shows a broader absorption peak, and as the degree of association increases, the absorption peak moves to a lower wave number;

[0044] Carbonyl (C=O): The stretching vibration of carbonyl is between 1750 and 1680 cm -1 There is a strong absorption peak at

[0045] Carbon-carbon double bond (C=C): The stretching vibration of carbon-carbon double bond in olefins is between 1680 and 1640 cm -1 There is an absorption peak at

[0046] Carbon-carbon triple bond (C≡C): The stretching vibration of the carbon-carbon triple bond in alkynes is between 2250 and 2100 cm -1 There is an absorption peak.

[0047] Aromatic ring (Ar-H): The stretching vibration of hydrogen atoms on the aromatic ring usually appears at 3100-3000cm -1 , while the skeleton vibration of the aromatic ring is between 1600 and 1450 cm -1 There is an absorption peak.

[0048] Amino group (NH): The stretching vibration of amino group appears at 3500-3200 cm -1 , which may overlap with the stretching vibration region of the hydroxyl group.

[0049] Carboxyl (COOH): The stretching vibration of carboxyl is between 1750 and 1700 cm -1 There is an absorption peak.

[0050] After obtaining the combustion product composition data, the embodiment of the present application can determine whether the vehicle needs to alarm based on the product composition, product concentration and other information. For example, if the CO concentration is too high, it means incomplete combustion. If it is entirely treated by the exhaust gas treatment device, the treatment effect is not ideal and it is difficult to guarantee the treatment effect. Under extreme conditions, if exhaust gas leakage occurs, it is easy to enter the vehicle cabin and affect the safety of passengers in the vehicle. Therefore, the embodiment of the present application can determine whether the vehicle meets the preset alarm conditions based on the combustion product composition data, and push the corresponding combustion warning signal to the preset terminal when the vehicle meets the preset alarm conditions. The preset terminal can be a vehicle terminal, such as displaying through a central control icon, an instrument panel icon, or reminding through voice broadcast, etc.; the preset terminal can also be a mobile terminal, such as a mobile phone device associated with the vehicle, so that the owner can obtain the status of the vehicle in time; the preset terminal can also be a maintenance terminal, and the maintenance personnel can obtain the vehicle status in advance through the maintenance terminal to speed up the maintenance progress; the preset terminal can also be a car company terminal, and the technical personnel of the car company can make technical improvements based on the feedback data.

[0051] In the actual implementation process, after identifying the element content in the combustion products, the embodiment of the present application can optimize the combustion by adjusting the three indicators of ignition angle, injection pulse width, and intake air volume. For example, if the CO concentration is high and the combustion is sufficient, the combustion can be made more complete by increasing the intake air volume, reducing the injection pulse width, and adjusting the ignition angle.

[0052] Among them, the preset alarm conditions can be set accordingly by technical personnel in this field according to the different components of the combustion products, and no specific restrictions are made here.

[0053] Optionally, in one embodiment of the present application, the combustion product composition data in the combustion chamber is obtained according to the optical signal, including: preprocessing the optical signal to obtain spectral data that meets preset quality conditions; using the spectral data as an index, querying at least one component of the combustion product in a preset spectral database, and quantifying each component to obtain a corresponding spectral intensity; based on the spectral intensity and a pre-constructed concentration-absorbance relationship, calculating the concentration of each component of the combustion product, and obtaining the combustion product composition data based on the concentration and at least one component.

[0054] In the actual implementation process, the embodiment of the present application can perform data processing and analysis on the optical signal after obtaining the optical signal, for example, baseline correction: eliminating the influence of background noise and other interference factors, so as to obtain spectral data that meets the quality conditions, wherein the quality conditions can be different depending on the selected spectrometer, and can be set accordingly by technical personnel in this field according to actual conditions, and no specific restrictions are made here.

[0055] Furthermore, the embodiments of the present application can perform spectral analysis and use a spectral database of known standard substances to identify and quantify the components in the combustion products, that is, using the spectral data as an index to search for at least one component of the combustion products in a preset spectral database, wherein the preset spectral database can be a database that records standard data in a big data spectral database, or it can be a spectral database provided by a car manufacturer, or it can be a spectral database set by the vehicle itself.

[0056] The embodiments of the present application can perform quantitative analysis, quantify each component, obtain the corresponding spectral intensity, and calculate the concentration of each component based on the spectral intensity and the known concentration-absorbance relationship.

[0057] Furthermore, the embodiment of the present application can extract the spectral intensity of each combustion product component from the collected spectral data, and calculate the concentration of each component based on the constructed concentration-absorbance relationship.

[0058] Among them, the embodiments of the present application can use standard gas samples of known concentration to construct a standard curve, establish a mathematical relationship between concentration and absorbance, and regularly use gas samples of known concentration for calibration to ensure measurement accuracy.

[0059] Optionally, in one embodiment of the present application, whether the vehicle meets the preset alarm conditions is determined based on the combustion product composition data, including: screening out incomplete combustion components from the combustion products, and detecting the concentration corresponding to the incomplete combustion components; determining whether the concentration corresponding to the incomplete combustion components is greater than a preset safety warning threshold; if the concentration corresponding to the incomplete combustion components is greater than the preset safety warning threshold, it is determined that the vehicle meets the preset alarm conditions.

[0060] It is understandable that there are multiple components in the combustion products of a vehicle's internal combustion engine, some of which, such as incomplete combustion products, may pose a potential threat to vehicle safety and the environment when their concentrations are too high.

[0061] For example, CO, NO x , HC (unburned hydrocarbons), PM (particulate matter) and SO x (sulfur oxides), etc.

[0062] Among them, the preset safety warning threshold can be determined by the concentration of combustion products in the combustion chamber, the treatment efficiency and capacity of the exhaust gas treatment device and relevant emission standards, and no specific restrictions are made here.

[0063] When the concentration corresponding to the incomplete combustion component is greater than a certain safety warning threshold, the embodiment of the present application can determine that the vehicle can sound an alarm, thereby reminding the user to promptly detect vehicle abnormalities and perform maintenance in a timely manner, thereby ensuring the vehicle's driving safety and environmental safety.

[0064] Optionally, in one embodiment of the present application, after pushing the corresponding combustion warning to the preset terminal, it also includes: using the combustion product composition data as an index, matching the corresponding fuel injection adjustment strategy in the preset fuel injection quantity database; adjusting the vehicle's fuel injection quantity, intake valve and exhaust valve opening time based on the fuel injection strategy, so that the concentration corresponding to the incomplete combustion component is less than or equal to the preset safety warning threshold.

[0065] As a possible implementation method, the embodiment of the present application can match the corresponding fuel injection adjustment strategy according to the combustion product composition data, especially the concentration of incomplete combustion products.

[0066] For example, if it is necessary to reduce CO and HC in the combustion products, the embodiment of the present application can increase the fuel injection amount. If the concentration of CO and HC is high, it indicates that the fuel combustion is incomplete, and the combustion conditions can be improved by slightly increasing the fuel injection amount. The embodiment of the present application can also adjust the ignition timing. Advancing the ignition timing can help improve combustion efficiency and reduce unburned hydrocarbons.

[0067] Another example is the need to reduce NO in combustion products. x , the embodiment of the present application can reduce the amount of fuel injection, if NO x A high concentration indicates that the combustion temperature is too high. The combustion temperature can be lowered by reducing the amount of fuel injected, thereby reducing NO x The embodiment of the present application can also use the exhaust gas recirculation system to introduce a certain proportion of exhaust gas to participate in combustion, which can reduce the combustion temperature and reduce NO x Generation of.

[0068] When executing the corresponding fuel injection adjustment strategy, the embodiment of the present application can also perform closed-loop control by monitoring the composition of combustion products in real time, dynamically adjusting the fuel injection amount and other related parameters based on feedback information, and using machine learning algorithms to continuously optimize the control strategy, improve combustion efficiency and reduce emissions.

[0069] Optionally, in one embodiment of the present application, before pushing the corresponding combustion warning to the preset terminal, it also includes: recording the combustion product composition data; and generating a combustion warning signal based on the combustion product composition data.

[0070] In some embodiments, the embodiments of the present application can also record the combustion product composition data detected each time, and then when generating a combustion warning signal, the data detected this time is made public, so as to facilitate subsequent vehicle adjustments and thereby improve the user's driving experience.

[0071] According to the internal combustion engine combustion warning method of the vehicle proposed in the embodiment of the present application, after the vehicle is ignited, a signal generating device can be used to emit light passing through the combustion product based on the ignition signal, and a collection device can be used to collect the light to obtain a corresponding light signal, and the combustion product composition data in the combustion chamber can be obtained based on the light signal, so as to judge whether the vehicle meets the preset alarm condition based on the combustion product composition data, and when the vehicle meets the preset alarm condition, the corresponding combustion warning signal is pushed to the preset terminal, and the combustion state in the cylinder is monitored and warned in real time to obtain multi-angle combustion data, and the terminal is warned in time, which improves the driving safety of the vehicle on the one hand, and facilitates the timely maintenance of relevant technical personnel on the other hand, and improves the reliability of the internal combustion engine and the troubleshooting processing rate. Thus, the technical problems in the related technology that the combustion state in the engine cylinder is controlled by monitoring a single parameter, resulting in insufficient monitoring data, relatively few monitoring dimensions, certain safety hazards, and slow problem processing rate due to insufficient data mastery, and it is difficult to directly hit the problem pain points, etc.

[0072] Next, the internal combustion engine combustion warning device for a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0073] Figure 4 It is a block diagram of a combustion warning device for an internal combustion engine of a vehicle according to an embodiment of the present application.

[0077] The warning module 300 is used to obtain the combustion product composition data in the combustion chamber according to the optical signal, and judge whether the vehicle meets the preset alarm conditions based on the combustion product composition data, and push the corresponding combustion warning signal to the preset terminal when the vehicle meets the preset alarm conditions.

[0078] Optionally, in one embodiment of the present application, the early warning module 300 includes: a processing unit, a query unit and a calculation unit.

[0079] The processing unit is used to pre-process the optical signal to obtain spectral data that meets preset quality conditions.

[0080] The query unit is used to query at least one component of the combustion product in a preset spectrum database using the spectrum data as an index, and quantify each component to obtain a corresponding spectrum intensity.

[0081] The calculation unit is used to calculate the concentration of each component of the combustion product based on the spectral intensity and the pre-constructed concentration-absorbance relationship, and obtain the combustion product composition data based on the concentration and at least one component.

[0083] The detection unit is used to screen out incomplete combustion components from the combustion products and detect the concentrations of the incomplete combustion components.

[0084] The judgment unit is used to judge whether the concentration corresponding to the incomplete combustion component is greater than a preset safety warning threshold.

[0085] The determination unit is used to determine that the vehicle meets a preset alarm condition when the concentration corresponding to the incomplete combustion component is greater than a preset safety warning threshold.

[0088] The regulating module is used to regulate the fuel injection amount, the opening time of the intake valve and the exhaust valve of the vehicle based on the fuel injection strategy so that the concentration corresponding to the incomplete combustion component is less than or equal to the preset safety warning threshold.

[0089] Optionally, in one embodiment of the present application, the internal combustion engine combustion warning device 10 of the vehicle further includes: a recording module and a generating module.

[0090] Among them, the recording module is used to record the combustion product composition data.

[0091] A generation module is used to generate a combustion warning signal based on the combustion product composition data.

[0092] It should be noted that the above explanation of the embodiment of the vehicle internal combustion engine combustion warning method is also applicable to the vehicle internal combustion engine combustion warning device of this embodiment, and will not be repeated here.

[0093] According to the internal combustion engine combustion warning device of the vehicle proposed in the embodiment of the present application, after the vehicle is ignited, a signal generating device can be used to emit light passing through the combustion product based on the ignition signal, and a collection device can be used to collect the light to obtain a corresponding light signal, and the combustion product composition data in the combustion chamber can be obtained based on the light signal, so as to judge whether the vehicle meets the preset alarm condition based on the combustion product composition data, and when the vehicle meets the preset alarm condition, the corresponding combustion warning signal is pushed to the preset terminal, and the combustion state in the cylinder is monitored and warned in real time to obtain multi-angle combustion data, and a warning is issued to the terminal in time, which improves the driving safety of the vehicle on the one hand, and facilitates the timely maintenance of relevant technical personnel on the other hand, and improves the reliability of the internal combustion engine and the troubleshooting processing rate.
