Description

Technical Field

[0001] This application relates to the field of simulation computing, and in particular to a simulation method, apparatus and storage medium for simulating cylinder deactivation and optimizing valve mechanism. Background Technology

[0002] Cylinder deactivation technology, also known as variable displacement technology, refers to the process of cutting off the fuel supply, ignition, and intake and exhaust of some cylinders when the engine is running under partial load. This stops the operation of some cylinders, increasing the load rate of the remaining working cylinders, thereby improving efficiency and reducing fuel consumption.

[0003] Currently, research on cylinder deactivation technology is limited. The impact of valve mechanism movement during cylinder deactivation on various engine performance parameters is not fully understood, and existing simulation methods significantly simplify the process, resulting in substantial differences from actual engine cylinder deactivation.

[0062] In the process of engine research and development, simulation calculation, as a means of reproducing the engine's working process and performance results through calculation software, and to a certain extent, providing high-confidence prediction results through technical control, has become an important development tool in the engine research and development process.

[0063] Based on this, this application provides a simulation method for simulating cylinder deactivation and optimizing valve mechanism, which is used to optimize engine cylinder deactivation mode and valve mechanism.

[0064] It should be noted that the simulation method for cylinder deactivation and valve mechanism optimization provided in this application can be applied to terminals, systems, and servers. For example, the terminal can be a smartphone, computer, tablet, smart TV, smartwatch, portable computer, or a desktop computer, etc. For ease of explanation, this application uses the terminal as the execution subject for illustration.

[0065] Please see Figure 1 , Figure 1 This is a schematic flowchart of an embodiment of the simulation method for simulating cylinder deactivation and optimizing valve mechanism provided in this application. The simulation method includes:

[0066] 101. Obtain engine data and test data;

[0067] In this embodiment, the engine data refers to the physical structure data of the engine required to build the engine model, such as cylinder bore, stroke, connecting rod length, compression ratio, pipe volume, valve profile, etc. The test data refers to the basic test data that characterizes the engine's performance, such as engine universal test data and engine external characteristic test data.

[0068] 102. Based on the engine data and the test data, complete the calibration of the basic engine model;

[0069] In this embodiment, the calibration process is a conventional model calibration process. The calibration of the engine model aims to achieve high accuracy so that it can reflect the performance of a real engine. This embodiment simulates the valve mechanism action and engine performance of a 6-cylinder engine operating in a 1 / 2 cylinder deactivation mode using simulation software. That is, the basic engine model is a 6-cylinder engine model operating in a 1 / 2 cylinder deactivation mode.

[0070] 103. Set preset actions for cylinders and valve mechanisms in cylinder deactivation mode;

[0071] In this embodiment, after obtaining the basic engine model in step 102, it is necessary to decompose the execution actions of the cylinders and valve mechanisms when the engine performs a cylinder deactivation, and use the decomposed actions as action presets. For example, in the 1 / 2 cylinder deactivation mode of a 6-cylinder engine, the original working cycle is 6 cylinders working alternately in the firing order of 1-5-3-6-2-4. If it is to switch to a new working cycle in which only 3 cylinders work alternately, the cylinder actions and firing order need to be reset, and the required valve actions also need to be considered. That is, the original working cycle can be adjusted to work cylinders 1-6-2 first, then cylinders 4-3-5, and the valve actions can be adjusted accordingly. The above adjustment is the new working cycle, and the actions of the cylinders and valves at this time are set as action presets.

[0072] It should also be noted that the preset action is any reasonable action that can be achieved, and it is adjusted according to different changing factors, such as the uniformity of engine operation or the uniformity of exhaust; the action of the valve is not simply a matter of fully opening or fully closing.

[0073] 104. Add cylinder deactivation mode switch quantity and valve actuation switch quantity;

[0074] In this embodiment, after completing the cylinder deactivation and valve actuation presets, necessary switching parameters need to be added. These parameters facilitate the switching of cylinder deactivation modes and the changes in valve actuation. The cylinder deactivation mode switching parameters correspond to different cylinder deactivation modes. For example, when the cylinder deactivation mode switching parameter is 0, the engine operates in normal mode; when the cylinder deactivation mode switching parameter is 1, the engine switches to 1 / 2 mode. Similarly, the valve mechanism operates in the same manner; the valve actuation switching parameters correspond to different valve actuations to meet the engine control requirements during cylinder deactivation.

[0075] 105. Modify the interface of the basic engine model and add signal streams;

[0076] In this embodiment, necessary interfaces are added to transmit essential signal streams to meet the input and output requirements of the code module in the following step 106, and to facilitate interaction between modules. For example, the control module needs to receive switching command signals for cylinder deactivation mode and valve actuation mode, monitor the current operating status of the cylinder, process the inputs, and then send specific execution actions to the cylinder and valve mechanism.

[0077] 106. Add a code module and associate it with the cylinder deactivation mode switch, the valve action switch, and the interface to realize the control of the cylinder and valve action;

[0078] In this embodiment, after adding the necessary interfaces and signal flows, code is added to the control module to generate a code module. This code module is then associated with the switch quantities and interfaces, thereby implementing the specific actions of the cylinders and valves through the code. For example, using the engine cycle number for logical judgment, to achieve the 1 / 2 cylinder deactivation mode, the control module receives the currently running cycle number code, performs logical judgment on which 3 cylinders need to work within this cycle, and then sets the valve actions for these 3 cylinders.

[0079] For example, the cylinder action is defined by the firing order (piston phase) and the fuel injector's injection action. The specific implementation of valve action requires further decomposition of each cycle, setting the required valve actions sequentially according to the cylinder's action. If the first cycle requires cylinders 1-6-2 to work, and the second cycle requires cylinders 4-3-5 to work, then a separate triggering mechanism is set for each working cylinder. That is, code is added to the control module to enable cylinders 1-6-2 to open their valves normally, while cylinders 4-3-5 act as required. Then, the generated code module is associated with the corresponding switch quantities and interfaces.

[0080] 107. Determine whether the cylinder and valve actions conform to the preset actions; if yes, proceed to step 111; otherwise, proceed to step 108.

[0081] In this embodiment, steps 104 to 105 control the movement of the cylinder and valve through code. After the control is completed, it is necessary to check whether the movement of the cylinder and valve conforms to the preset movement, and then determine whether the code can run correctly.

[0082] 108. Compare the cylinder and valve actions with the preset actions;

[0083] In this embodiment, if the cylinder and valve actions are inconsistent with the preset actions, it is necessary to compare the cylinder and valve actions with the preset actions, analyze the reasons for the differences, and check whether the code is correct.

[0084] 109. Based on the aforementioned differences, adjust the logic executed by the code module to obtain new cylinder and valve actions;

[0085] In this embodiment, if inconsistencies occur, the code module logic of step 106 needs to be debugged. For example, when constructing the cylinder and valve action of the 1 / 2 cylinder deactivation mode using this method, if abnormal valve opening / closing causes a certain cylinder of the engine to malfunction, the engine to malfunction evenly, or to malfunction in outputting stable torque at the flywheel end, the code needs to be adjusted to ensure that the valve opens or closes normally.

[0086] 110. After adjustment, determine whether the new cylinder and valve actions conform to the preset actions, and repeat until the cylinder and valve actions conform to the preset actions;

[0087] 111. Fix the code module, the cylinder deactivation mode switch quantity, the valve action switch quantity, the interface, and the signal stream to obtain the fixed structure.

[0088] In this embodiment, after completing steps 104 to 110, when the cylinder and valve actions conform to the preset actions, the code module, the cylinder deactivation mode switch quantity, the valve action switch quantity, the interface, and the signal stream are fixed and solidified into a structure that can work correctly. For example, if the 1 / 2 cylinder deactivation mode has been debugged and confirmed to be correct, the code module, the cylinder deactivation mode switch quantity, the valve action switch quantity, the interface, and the signal stream can be fixed and solidified into the structure required for the 1 / 2 cylinder deactivation mode.

[0089] The simulation method for cylinder deactivation and valve mechanism optimization in this application establishes a model structure, sets preset cylinder and valve actions, controls cylinder and valve actions through code, and then compares the cylinder and valve actions under code control with the preset actions. This provides an effective control method for various complex cylinder deactivation and valve action modes in engine development, provides more possibilities for valve variation, and can obtain engine performance parameters under various complex cylinder deactivation and valve change modes, making the simulation results closer to reality.

[0090] In practice, after completing the simulated cylinder deactivation mode and fixing the debugged structure, it is necessary to repeatedly adjust and optimize the valve structure parameters and engine cylinder deactivation mode until an optimized result that meets the requirements is obtained. This application provides another embodiment to illustrate this in detail:

[0091] See Figure 2 This embodiment includes:

[0092] 201. To enable the engine to operate under the fixed structure described above;

[0093] In this embodiment, the fixed structure is the structure obtained in step 111 of the previous embodiment, that is, the structure is optimized.

[0094] 202. Calculate the performance of the engine and extract the calculation results;

[0095] 203. Analyze whether the calculation results meet the indicators. If not, proceed to step 204; if yes, proceed to step 205.

[0096] In this embodiment, the performance of the engine during or after operation is obtained, and the calculation results are calculated and extracted. Further analysis is conducted to determine whether the calculation results meet the expected indicators. For example, in the cylinder deactivation mode, an in-cylinder mass, cylinder temperature, cylinder pressure, intake and exhaust process, engine specific fuel consumption, air-fuel ratio, pumping loss, etc., of the working and non-working cylinders can be analyzed in depth to determine whether they meet the requirements and whether there is room for optimization.

[0097] 204. Optimize the valve mechanism of the fixed structure and re-compare the optimized calculation results and indicators;

[0098] In this embodiment, if the calculation results do not meet the expected indicators or there is room for optimization, the valve mechanism can be adjusted. For example, the valve mechanism can be subjected to dynamic analysis to obtain the analysis results. Based on the analysis results, the valve structure can be adjusted or replaced, and recalculated, analyzed and optimized until the indicator requirements are met to obtain the ideal working mode.

[0099] 205. Output the optimized structure and the final performance results of the engine.

[0100] In this embodiment, after optimization, the optimized structure and the final performance result of the engine can be output as the optimization result. The optimization result can be used to guide the actual cylinder deactivation mode control strategy and related hardware development work.
