[0040] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.
[0041] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.
[0042] The terms "first," "second," etc., used 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 terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.
[0043] To facilitate understanding of this application, the relevant concepts involved in this application will be explained below:
[0044] Ignition coil: Responsible for converting the low voltage provided by the vehicle battery into a high voltage (usually tens of thousands of volts) to generate a spark to ignite the fuel mixture in the engine cylinders. The ignition coil works on the principle of electromagnetic induction, converting low-voltage electricity into high-voltage electricity to ensure normal engine operation and smooth combustion. The automotive ignition coil mainly consists of the ignition coil and a switching device.
[0045] Currently, methanol fuel is prone to stratification and emulsification after absorbing water, directly leading to difficulty in engine starting, reduced power, and poor combustion stability. To address this problem, this application provides an engine ignition control method. The engine ignition control method of this application, as illustrated in the accompanying drawings, will be described in detail below.
[0046] See Figure 1 , Figure 1This is a flowchart illustrating an engine ignition control method provided in an embodiment of this application. Figure 1 As shown in the figure, an engine ignition control method provided in this application embodiment is applied to an engine controller (ECU, Electronic Control Unit) and may include the following steps S101 to S102, which are described in detail below.
[0047] S101, obtain the actual water content of the methanol fuel in the target engine.
[0048] In this embodiment, the target engine is the engine to be ignition controlled. For the target engine, the engine controller can obtain the actual water content of its methanol fuel using an existing methanol-water content sensor, which can be specifically a water content percentage.
[0049] In one possible implementation, to ensure timely in-cylinder combustion control of the engine during vehicle operation, this embodiment deploys a methanol-water content sensor in the methanol fuel supply system. The signal from this sensor is then introduced into the engine controller. During vehicle operation, the methanol-water content sensor continuously monitors the water content of the methanol fuel in the supply system. The engine controller adjusts the ignition energy of the ignition coil based on the water content, thus achieving in-cylinder combustion control under different water contents in the methanol fuel. See also... Figure 2 , Figure 2 This is another schematic flowchart illustrating an engine ignition control method provided in an embodiment of this application. Figure 2 As shown in the embodiment of this application, an engine ignition control method is provided, wherein step S101, "obtaining the actual water content of methanol fuel in the target engine", can be performed using the following step S201, which will be described in detail below.
[0050] S201, the actual water content is obtained by deploying a methanol water content sensor in the methanol fuel supply system.
[0051] See Figure 3 , Figure 3 This is a schematic diagram of an engine ignition control system provided in an embodiment of this application. Figure 3 As shown in the figure, an engine ignition control system provided in this application includes a methanol fuel supply system A, an engine controller B, and an ignition coil C. See also... Figure 3A methanol-water content sensor is deployed in the methanol fuel supply system A. The methanol-water content sensor measures the actual water content of the methanol fuel in real time and sends the actual water content to the engine controller B. The engine controller B adjusts the ignition energy of the ignition coil C according to the actual water content to achieve in-cylinder combustion control under different water contents of methanol fuel.
[0052] S102, adjust the ignition energy of the ignition coil according to the actual water content to control the ignition of the target engine; wherein, the ignition energy of the ignition coil is positively correlated with the actual water content.
[0053] In this embodiment, after obtaining the actual water content of the methanol fuel, the engine controller can adjust the ignition energy of the ignition coil according to the level of the actual water content. The ignition energy of the ignition coil is positively correlated with the actual water content, that is, the higher the actual water content, the greater the ignition energy of the ignition coil. This allows for successful ignition when the methanol fuel is relatively thin by increasing the ignition energy, thus ensuring the stability of combustion in the engine cylinder.
[0054] In one possible implementation, since the ignition requirements of a vehicle differ between the starting phase and the engine running phase, the stability requirements for in-cylinder combustion are higher during engine running compared to the starting phase. To reduce battery energy consumption, the engine controller can adaptively adjust the ignition energy of the ignition coil according to different phases. In this regard, an engine ignition control method provided in this application embodiment, wherein step S102, "adjusting the ignition energy of the ignition coil according to the actual water content," can be implemented using the following steps, which are described in detail below.
[0055] The vehicle operation phase is determined, and the ignition energy of the ignition coil is adjusted according to the actual water content during the vehicle operation phase. The vehicle operation phase includes the starting phase and the engine operation phase, and the ignition energy adjustment during the starting phase is less than the ignition energy adjustment during the engine operation phase.
[0056] In this embodiment, the engine controller acquires the vehicle operating phase, which may include the starting phase before engine start and the engine operating phase during engine start-up. Furthermore, according to different vehicle operating phases, the ignition energy of the ignition coil is adjusted based on the actual water content. Under the same actual water content, the adjustment amount of the ignition energy of the ignition coil during the starting phase is less than that during the engine operating phase. Whether in the starting phase or the engine operating phase, the ignition energy of the ignition coil is adjusted according to the actual water content. Taking the starting phase as an example, the higher the actual water content, the greater the ignition energy of the ignition coil; the same applies to the engine operating phase.
[0057] In one possible implementation, the engine controller can determine the water content limit of methanol fuel according to national standards (i.e., the national standard limit for water content), and then dynamically adjust the ignition energy of the ignition coil based on the actual water content according to this national standard limit. See also Figure 4 , Figure 4 This is a partial flowchart illustrating an engine ignition control method provided in an embodiment of this application. Figure 4 As shown in the embodiment of this application, an engine ignition control method is provided, wherein step S102, "adjusting the ignition energy of the ignition coil according to the actual water content", may include the following steps S301 to S303, which are described in detail below.
[0058] S301, obtain the national standard limit for water content in methanol fuel and compare the actual water content with the national standard limit.
[0059] In this embodiment, the engine controller obtains the national standard limit for water content according to the specifications of methanol fuel, and then compares the actual water content with the national standard limit for water content.
[0060] S302, if the actual water content is less than the national standard limit for water content, the secondary coil in the ignition coil is controlled to output the first voltage.
[0061] In this embodiment, if the actual water content is less than the national standard limit for water content, it indicates that the water content in the methanol fuel does not exceed the standard. At this time, the engine controller can control the secondary coil in the ignition coil to output a lower voltage (i.e., the first voltage), thereby generating a spark to ignite the methanol fuel with a lower high voltage. It should be noted that the first voltage can be a fixed value (such as the voltage required for normal ignition energy) or a value positively correlated with the actual water content. This embodiment does not limit this.
[0062] S303, if the actual water content is greater than or equal to the national standard limit for water content, the secondary coil of the ignition coil is controlled to output a second voltage; wherein the second voltage is greater than the first voltage.
[0063] In this embodiment, if the actual water content is greater than or equal to the national standard limit for water content, it indicates that the water content of the methanol fuel has exceeded the standard. At this time, the engine controller can control the secondary coil in the ignition coil to output a higher voltage, thereby generating a spark to ignite the methanol fuel with a higher voltage. It should be noted that the second voltage is greater than the first voltage. The second voltage can be a fixed value or a value positively correlated with the actual water content. This embodiment does not limit this.
[0064] In one possible implementation, the water content limit for methanol fuel misfire (i.e., the water content misfire limit) can be determined experimentally. When the water content of the methanol fuel reaches this water content misfire limit, even controlling the ignition coil to output the highest ignition energy will not ignite the methanol fuel. This water content misfire limit is greater than the national standard limit for water content. Therefore, the engine controller can adjust the ignition energy of the ignition coil when the water content of the methanol fuel is between the national standard limit and the water content misfire limit. See also Figure 5 , Figure 5 This is another schematic flowchart illustrating an engine ignition control method provided in an embodiment of this application. Figure 5 As shown in the embodiment of this application, an engine ignition control method is provided, wherein step S303, "controlling the secondary coil of the ignition coil to output a second voltage", may include the following steps S401 to S402, which are described in detail below.
[0065] S401, obtain the water content misfire limit of methanol fuel and compare the actual water content with the water content misfire limit.
[0066] In this embodiment, the engine controller obtains the tested misfire limit for water content based on the specifications of methanol fuel, and then compares the actual water content with the water content misfire limit.
[0067] S402, if the actual water content is less than the water content misfire limit, the secondary coil of the ignition coil is controlled to output a second voltage.
[0068] In this embodiment of the application, if the actual water content is less than the water content misfire limit, that is, the actual water content is greater than or equal to the national standard limit for water content and less than the water content misfire limit, it means that although the water content of the methanol fuel has exceeded the standard, it can still be ignited by adjusting the ignition energy. At this time, the engine controller can control the secondary coil of the ignition coil to output the second voltage.
[0069] In one possible implementation, if the water content of the methanol fuel reaches the water content misfire limit, it is impossible to ignite the methanol fuel by adjusting the ignition energy. In this embodiment, a pre-combustion chamber ignition method can be introduced to attempt to ignite the methanol fuel. See also... Figure 6 , Figure 6 This is another schematic flowchart illustrating an engine ignition control method provided in an embodiment of this application. Figure 6 As shown in the embodiment of this application, an engine ignition control method is provided, wherein step S303, "controlling the secondary coil of the ignition coil to output a second voltage", may further include step S403, which will be described in detail below.
[0070] S403: If the actual water content is greater than or equal to the water content misfire limit, the target engine shall be ignited by means of pre-combustion chamber ignition.
[0071] In this embodiment, if the actual water content is greater than or equal to the water content misfire limit, it indicates that the methanol fuel cannot be ignited by adjusting the ignition energy. In this case, the engine controller controls the ignition of the target engine using pre-combustion chamber ignition. Specifically, flammable gases such as hydrogen can be introduced into the active pre-combustion chamber, so that the methanol fuel is first ignited by the spark plug in the active pre-combustion chamber during its entry. The resulting flame front flows out from the small holes on the surface of the active pre-combustion chamber, thereby igniting the methanol fuel in the cylinder.
[0072] Based on this, since the pre-combustion chamber ignition method cannot guarantee successful ignition when the water content of methanol fuel is too high, timely alarms can be triggered by monitoring the ignition results of the target engine. Therefore, the engine ignition control method provided in this application embodiment may further include the following steps, which are described in detail below.
[0073] Obtain the ignition result of the target engine, and output an alarm message if the ignition result is a misfire.
[0074] In this embodiment, the engine controller can determine the ignition result by monitoring the operating parameters of the target engine, such as the engine speed. If the rate of change of the engine speed increases, it indicates successful ignition; conversely, it indicates a misfire. When the ignition result is a misfire, an alarm message is output, such as sending a signal indicating that the methanol fuel water content exceeds the limit to the instrument panel, reminding the driver to replace the methanol fuel in time.
[0075] Based on the above description, the engine ignition control method provided in this application can measure the water content of methanol fuel in the engine in real time, and then adjust the ignition energy of the ignition coil according to the water content. The higher the water content of the methanol fuel, the greater the ignition energy of the ignition coil, which can successfully ignite the relatively lean methanol fuel, thereby ensuring the stability of combustion in the engine cylinder and improving engine power. In addition, by introducing national standard limits for water content and water content misfire limits, a step-wise adjustment of ignition energy can be achieved. When the water content reaches the water content misfire limit, ignition control continues to be achieved through pre-combustion chamber ignition, maximizing the success of methanol fuel ignition.
