Those skilled in the art will appreciate that the configuration shown in FIG. 1 does not constitute a limitation of a super-detonation differential verification device, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a super knock differentiation verification program.

An embodiment of the present invention provides a super knock difference verification method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the super knock difference verification method according to the present invention.
In this embodiment, the super-knock difference verification method includes the following steps:
step S10: and acquiring a target test environment, wherein the target test environment comprises a target fuel injection angle, a target injection time, a target VVT angle, a target ignition advance angle, a target air-fuel ratio, a target water temperature and a target after-cold temperature.
It should be noted that the execution subject of the embodiment is a controller of an automobile, and when the difference of the samples needs to be detected, the controller of the automobile may start to operate, or may be another device having the same function, which is not limited in this embodiment.
It is understood that the target test environment refers to the operating environment most suitable for performing the knock test, and includes a target fuel injection angle, a target injection time, a target VVT angle, a target spark advance angle, a target air-fuel ratio, a target water temperature, and a target after-cold temperature. For example, when the engine is a 1.5TGDI engine, the target test operating condition environment may be as shown in Table 1.
TABLE 1
It is understood that the target VVT angle includes a target VVT-I angle and a target VVT-E angle, while the target fuel injection angle includes a target primary injection angle and a target secondary injection angle.
Step S20: the frequency of engine super-knock is adjusted so that the engine meets test conditions.
It should be noted that, after the target test working condition environment is selected, it is still necessary to determine whether the frequency of occurrence of knocking of the current engine meets the test conditions, and if not, further adjustment is necessary.
Further, in order to improve the differentiation of sample test variability in the test, the adjusting the frequency of engine super-knocking so that the engine meets the test conditions comprises the following steps: acquiring adjustment parameters corresponding to a preset super detonation frequency range, wherein the adjustment parameters comprise at least one of water temperature, after-intercooling temperature, ignition advance angle, VVT angle and fuel injection angle; and adjusting the frequency of engine super knocking according to the adjusting parameters so that the engine meets the test conditions.
It is understood that the frequency of the engine super knocking required to meet the preset range in the test, and in the embodiment, the frequency of the engine super knocking should not be lower than 10 times/cycle.
In a specific implementation, if the current frequency of knocking of the engine does not meet the requirement, the frequency of knocking of the engine can meet the requirement by adjusting any one or more of parameters of water temperature, after-cold temperature, spark advance angle, VVT angle and fuel injection angle, and meanwhile, in a specific adjustment process, the parameter adjustment specification and requirements can be shown in table 2, and certainly, other requirements can be met, which is not limited in this embodiment.
Step S30: and carrying out super detonation on the engine based on the target test environment to obtain effective sample data corresponding to a detonation result.
It should be noted that after the target test working condition environment meets the requirements, different test samples are added to the engine to perform the super-detonation cycle test, so as to obtain effective data of detonation test results corresponding to the different test samples.
In the concrete implementation, in order to ensure the smooth operation of the super detonation test and improve the validity and consistency of the test result, the test requires that the shutdown fault cannot occur in the process of the cycle test operation.
Further, in order to make the result of the sample test more accurate, it is necessary to clean the engine before the test, and before obtaining the valid data of the sample corresponding to the knocking result, the method includes: acquiring a cleaning instruction; determining corresponding cleaning conditions according to the cleaning instructions; and washing the engine based on the washing condition so that the engine meets the test condition.
TABLE 2
It is understood that the acquisition of the washing command refers to a command for washing the engine, and the engine is washed after receiving the command for washing the engine.
It is understood that the washing condition is a washing condition that enables the engine to satisfy the test condition. For example, in actual operation, after a cleaning instruction sent by a user is received, the obtained cleaning condition is that original engine oil in an engine is drained, the oil drainage time is not less than 15 minutes, and then a new test sample is added; after adding a new test sample, starting the engine to an idle speed, keeping the idle speed for five minutes, then discharging the test sample serving as cleaning oil, wherein the oil discharging time is not less than 15 minutes, and then replacing an oil filter and adding the new test sample to the engine.
Further, in order to eliminate the influence of carbon deposition in the engine on the super knock test, the engine needs to be carbon-cleaned before the super knock test, and before super knock is performed on the engine based on the target test working condition and effective data of a sample corresponding to a knock result is obtained, the method further includes: acquiring a carbon removal instruction; acquiring carbon removal working conditions corresponding to different preset time values according to the carbon removal instruction; and starting the engine to remove carbon based on the carbon removal working condition so that the engine meets the test conditions.
It should be noted that different working conditions under the carbon removal working condition correspond to different test times, the test time is a preset time value, and meanwhile, certain transition time and specific boundary conditions exist between different carbon removal working conditions, for example, the carbon removal working condition in this embodiment may be as shown in table 3, and other engine working conditions, transition time, test time, and specific boundary conditions may also exist in actual operation, which is not limited in this embodiment.
TABLE 3
Step S40: and obtaining the difference verification result of the target sample according to the effective data of the sample.
It should be noted that after obtaining the valid data of the sample, the difference verification results between different test samples are finally obtained based on the valid data and analysis.
Further, in order to ensure accuracy of a super-knock test result and obtain a more accurate difference result between samples, the super-knock is performed on the engine based on the target test environment, and after obtaining valid data of the sample corresponding to the knock result, the method further includes: judging whether the effective data of the sample meet a test preset value; and if the effective data of the sample meet the preset test value, obtaining a difference verification result of the target sample according to the effective data of the sample.
In the specific implementation, the comparison and verification of the difference results can be performed only when the valid data of the sample meets the preset test value, and if the valid data of the current sample does not meet the preset test value, the super-knock test needs to be performed on the sample again. For example, if the currently set test preset value is 5, each test sample has at least 5 sets of valid data, and a shutdown fault must not occur during the super knock test, and if a shutdown fault occurs or the valid data of a test sample is less than 5 sets, the test sample needs to be retested.
In the embodiment, a target test environment is obtained, and the target test environment comprises a target fuel injection angle, a target injection time, a target VVT angle, a target ignition advance angle, a target air-fuel ratio, a target water temperature and a target after-cold temperature; adjusting the frequency of engine super-knocking so that the engine meets test conditions; performing super detonation on the engine based on the target test environment to obtain effective sample data corresponding to a detonation result; and obtaining the difference verification result of the target sample according to the effective data of the sample. By the mode, the inhibition effect of the engine on the super detonation can be evaluated when the engine uses different products, the difference of the different products for inhibiting the super detonation is obtained, and meanwhile, a certain promoting effect can be achieved on the research and development of the products.

step S301: and carrying out a super-detonation circulation test on the engine based on the target test working condition, wherein the circulation test comprises a super-detonation pre-running circulation test and a super-detonation circulation test.
It should be noted that, in actual operation, in order to ensure that the boundary conditions meet the requirements during the super knock test and ensure the consistency of the engine state, the cycle tests include a super knock pre-run cycle test and a super knock cycle test.
Further, the cycle testing of super knocking the engine based on the target test environment includes: acquiring idling, preset rotating speed, full speed and full load corresponding to different preset time values and a shutdown condition based on the target test environment; carrying out a super-detonation pre-running circulation test according to the idle speed, the preset rotating speed and the shutdown working condition corresponding to the different preset time values; and carrying out a super detonation circulation test according to the idle speed, the preset rotating speed, the full speed and the full load corresponding to the different preset time values and the shutdown working condition.
It should be noted that the super knock pre-run cycle test is performed based on pre-run conditions of different conditions, for example, as shown in table 4, the current super knock pre-run cycle test is performed under different engine conditions.
