[0092] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0093] According to the first aspect of this application, referring to Figures 1 to 3 This application provides an atomization system 100, which can be at least part of an ignition system 200, such that a second aspect of this application also provides an ignition system.

[0094] Specifically, the ignition system 200 is used, for example, to ignite the engine 10 of a vehicle, such that the engine 10 is part of the ignition system 200. More specifically, the ignition system 200 is particularly suitable for engines 10 that burn liquid fuels such as gasoline.

[0095] The ignition system 200 includes at least an atomizing system 100 and an ignition device 101 that are interconnected.

[0096] The ignition device 101 can be used, for example, to ignite the fuel in the engine 10. Of course, depending on other usage scenarios of the ignition system 200, the ignition device 101 can also be used in other devices, such as gas stoves. This application does not impose any limitations on this. The following mainly describes the applicable scenarios of the ignition device 101 when applied to the engine 10, so as to specifically illustrate the inventive concept of this application.

[0097] The atomizing system 100 includes an atomizing device 102 and an output flow path 112.

[0098] The atomizing device 102 is used to obtain atomized fuel. The atomized fuel mentioned in this application refers to fuel in a mist-like state. Accordingly, the atomized fuel is considered to be fuel to be atomized before it is atomized by the atomizing device 102. More specifically, the atomizing device 102 can be used, for example, to atomize the fuel used in the engine 10. The output flow path 112 is used to connect to the ignition device 101. The ignition device 101, for example, is part of the engine 10 and is used to ignite the fuel entering the engine 10. The output flow path 112 is connected to the atomizing device 102 so that the output flow path 112 is adapted to deliver the atomized fuel to the ignition device 101. Taking gasoline as an example, when gasoline enters the atomizing device 102, it is atomized by the atomizing device 102 before entering the ignition device 101, which makes the gasoline appear as a mist within the ignition device 101, thus facilitating the combustion of gasoline.

[0099] In this way, after the fuel is atomized into atomized fuel by using the atomizing device 102, it is delivered to the ignition device 101 through the output flow path 112. When applied to the combustion of liquid fuels such as gasoline, this fuel supply method is conducive to the fuel being fully atomized before combustion, increasing the air-fuel ratio in the pre-combustion zone, reducing the possibility of wet walls, thereby achieving lean combustion in the main combustion chamber 11 of equipment such as engines, and improving combustion efficiency.

[0100] As a specific embodiment, the ignition system 200 is provided with a combustion chamber 200a, which provides a spatial area for fuel combustion. The output flow path 112 is connected to the combustion chamber 200a to deliver atomized fuel to the combustion chamber 200a, which is, for example, a chamber formed inside the engine 10, so that fuel can enter the engine 10 for combustion.

[0101] In some embodiments, at least a portion of the combustion chamber 200a is configured as a pre-combustion chamber 101b, which is connected to the atomizing device 102 via an output flow path 112 for supplying atomized fuel. This configuration involves igniting the atomized fuel within the pre-combustion chamber 101b, and then using the fuel in the pre-combustion chamber 101b to ignite other fuels within the engine 10, which promotes complete fuel combustion.

[0102] In some embodiments, refer to Figure 1 and Figure 2 As shown, the atomizing device 102 includes a heating unit 102a. The heating unit 102a is used to heat and atomize the fuel entering the atomizing device 102 to obtain atomized fuel. In this way, the heating unit 102a allows liquid fuels such as gasoline to be atomized more quickly, thereby ensuring that the fuel passing through the atomizing device 102 is fully atomized, facilitating subsequent ignition of the fuel in the ignition device 101.

[0103] As a specific embodiment, the heating unit 102a may have a heating nozzle, which forms a nozzle orifice through which fuel is passed, allowing the fuel to be atomized to pass. The heating nozzle is adapted to heat and atomize the passing fuel. In a more specific embodiment, the heating nozzle may have an electric heating wire integrated thereon, thereby enabling the heating nozzle itself and the fuel passing through the nozzle orifice to be heated.

[0104] In a more specific embodiment, the atomizing device 102 may be, for example, a fuel injector with an electric heater, namely the heating unit 102a mentioned above. Gasoline or other fuel is sprayed from the nozzle of the fuel injector, and at the same time, the electric heater heats the nozzle and the fuel in the nozzle, thereby achieving heating and atomization of the fuel.

[0105] Of course, other types of atomizing devices 102 can also be used to heat and atomize the fuel, and this application does not limit this.

[0106] In the atomization system 100 provided in this application, the fuel to be atomized, which is utilized by the atomizing device 102, can be provided by the second fuel tank 117. In some embodiments, refer to Figure 1 As shown, the atomization system 100 also includes: a second oil tank 117, a first oil supply path 107, and a fuel pump 108.

[0107] The second fuel tank 117 has a second storage chamber 117a for storing fuel. The second fuel tank 117 can be used to supply fuel to the main combustion chamber 11 of the engine 10 and / or the atomizing device 102. The second fuel tank 117 is connected to the atomizing device 102 to supply fuel to be atomized to the atomizing device 102.

[0108] A fuel pump 108 is disposed between the second fuel tank 117 and the atomizing device 102 for delivering fuel to be atomized from the second fuel tank 117 to the atomizing device 102.

[0109] The first fuel supply path 107 connects the second fuel tank 117, the fuel pump 108, and the atomizing device 102. For example, the first fuel supply path 107 connects between the second fuel tank 117 and the atomizing device 102. More specifically, the fuel pump 108 is disposed on the first fuel supply path 107 to deliver fuel from the second storage chamber 117a to the atomizing device 102. In this way, by providing the fuel pump 108 and the first fuel supply path 107, fuel stored in the fuel tank 104 can be delivered to the atomizing device 102.

[0110] In some embodiments, refer to Figure 1As shown, the atomization system 100 also includes a flow regulating device 109. The flow regulating device 109 is disposed on the first fuel supply path 107 to regulate the flow rate of fuel pumped to the atomizing device 102. Therefore, by setting the flow regulating device 109, the flow rate of fuel flowing to the atomizing device 102 can be controlled, thereby controlling the amount of fuel entering the ignition device 101 from the atomizing device 102. In actual use, this solution can flexibly adjust the air-fuel ratio in the ignition device 101 according to usage requirements, ensuring complete fuel combustion while avoiding problems such as knocking.

[0111] In some embodiments, the flow regulating device 109 includes a flow regulating valve disposed on the first fuel supply path 107. In a specific embodiment, when the ignition system 200 is integrated into a vehicle, the flow regulating valve is electrically connected to, for example, an on-board controller, so that the on-board controller can adjust the opening of the flow regulating valve to control the flow rate of fuel flowing from the first fuel supply path 107 to the atomizing device 102.

[0112] In some embodiments, refer to Figure 1 As shown, the atomization system 100 further includes an injector 110 and a second fuel supply path 111. The injector 110 is at least partially located within the ignition device 101 for injecting fuel into the ignition device 101. For example, when the ignition device 101 is part of the engine 10, at least a portion of the injector 110 is located within the main combustion chamber 11 of the engine 10 for injecting fuel into the main combustion chamber 11 of the engine 10; the injector 110 is connected to a fuel pump 108 so that the fuel pump 108 is adapted to pump fuel to the injector 110.

[0113] The second fuel supply path 111 is connected between the fuel pump 108 and the injector 110 so that the fuel pump 108 pumps fuel to the injector 110 when it is working. In this way, by providing the injector 110 and the second fuel supply path 111, the fuel in the second storage chamber 117a is injected into the main combustion chamber 11 of the engine 10 so that the fuel is burned in the main combustion chamber 11 as the engine 10 is working.

[0114] The atomizing device 102 enables liquid fuels such as gasoline to be fully atomized, facilitating rapid and complete combustion in the ignition device 101. In practical applications, the atomized fuel can be transported between the atomizing device 102 and the ignition device 101 via the output flow path 112. During cold starts, when the ambient temperature is low or the engine 10 has stopped operating, the fuel in these pipes may revert to a liquid state.

[0115] In some embodiments, refer to Figure 3As shown, the atomization system 100 also includes a collection device 103. The collection device 103 is used to collect residual fuel. The residual fuel mentioned in this application refers to fuel atomized by the atomizing device 102 but not entering the ignition device 101. The collection device 103 is connected between the atomizing device 102 and the ignition device 101, meaning that the collection device 103 can be used to collect at least a portion of the aforementioned atomized fuel that did not enter the ignition device 101 for combustion. In this way, by providing the collection device 103 between the atomizing device 102 and the ignition device 101 to collect the fuel that did not enter the ignition device 101 for combustion, these fuels can be further removed or re-entered into the atomizing device 102 for atomization, reducing the possibility of fuels such as gasoline accumulating between the atomizing device 102 and the ignition device 101, and preventing the fuel from entering the ignition device 101 without being atomized during a cold start of the engine 10, thus avoiding the problem of wet walls caused by this fuel entering the ignition device 101.

[0116] In some embodiments, refer to Figure 3 As shown, the atomization system 100 also includes: a first oil tank 104 and a collection flow path 105.

[0117] The first fuel tank 104 is connected to the collection device 103 for storing remaining fuel, and the first fuel tank 104 forms a first storage cavity 104a to accommodate the remaining fuel. Alternatively, the first fuel tank 104 and the second fuel tank can be the same fuel tank or two different fuel tanks.

[0118] The collection path 105 is connected to the collection device 103 for discharging the fuel collected in the collection device 103, so that the collection device 103 can continuously collect fuel.

[0119] In some embodiments, the collection flow path 105 is connected between the collection device 103 and the first fuel tank 104 to transport the remaining fuel collected by the collection device 103 to the first fuel tank 104. Specifically, the collection device 103 includes, for example, a housing 103a with an inner cavity 103b, connected between the atomizing device 102 and the preheating device. At least a portion of the atomizing device 102 is located within the inner cavity 103b, allowing atomized fuel to pass through the inner cavity 103b as it flows from the atomizing device 102 to the ignition device 101. This ensures that at least partially atomized fuel that does not enter the ignition device 101 is collected within the inner cavity 103b. The inner cavity 103b is connected to the storage cavity 104a via the collection flow path 105, allowing fuel in the inner cavity 103b to flow back from the collection flow path 105 to the fuel tank 104. This recovered fuel is then directed to the ignition device 101 or the main combustion chamber 11 of the engine 10 for combustion.

[0120] In some embodiments, refer to Figure 3As shown, the atomization system 100 also includes a backflow switch device 106. The backflow switch device 106 is disposed on the collection flow path 105 to control the flow of fuel from the collection device 103 to the storage chamber 104a. This prevents fuel from flowing from the collection flow path 105 to the fuel tank 104 when the ignition device 101 is normally igniting the fuel. However, when the engine 10 is not operating, the backflow switch device 106 can be controlled to connect the collection device 103 and the storage chamber 104a, allowing the fuel collected by the collection device 103 to flow back from the collection flow path 105 to the fuel tank 104.

[0121] In some embodiments, a backflow switch device 106 is provided on the collection flow path 105 to prevent the backflow of residual fuel.

[0122] As an example of a specific solution, the return switch device 106 includes, for example, an electromagnetic switch valve and / or a check valve disposed on the collection flow path 105. More specifically, when the ignition system 200 is integrated into a vehicle, the electromagnetic switch valve is electrically connected to, for example, the vehicle's on-board controller, thereby allowing the on-board controller to control the state of the electromagnetic switch valve, which in turn enables the electromagnetic switch valve to control the opening and closing of the collection flow path 105. The check valve, for example, allows residual fuel to flow unidirectionally from the collection device 103 to the first fuel tank 104.

[0123] In the specific plan, refer to Figure 1 and Figure 2 As shown, the output flow path 112 can be, for example, a pipe disposed between the atomizing device 102 and the ignition device 101, connecting the atomizing device 102 and the ignition device 101 through the output flow path 112. In a more specific embodiment, the output flow path 112 is disposed between the aforementioned housing 103a and the ignition device 101.

[0124] In some embodiments, refer to Figure 1 and Figure 2 As shown, the output flow path 112 is configured such that at least one section is formed on the cylinder head 12 of the engine 10. This application defines this section of the output flow path 112 formed on the cylinder head 12 of the engine as the flow channel 112a. That is, when the fuel flows from the atomizing device 102 to the ignition device 101, it will flow through the cylinder head 12. This arrangement is beneficial to utilize the heat on the cylinder head 12 when the engine 10 is working to further heat the fuel, so as to make the fuel more fully atomized.

[0125] In an optional configuration, the atomizing device 102 can be directly fixed to the cylinder head 12 of the engine, so that the atomizing device 102 is directly connected to the flow channel 112a. This shortens the length of the atomized fuel delivery pipeline, allowing the fuel to be atomized and delivered to the ignition device 101 more quickly, thus ensuring that the atomized fuel entering the ignition device 101 remains in an atomized state to a greater extent.

[0126] As a specific solution, the ignition device 101 may have a pre-combustion chamber 101b, as described above, so that the interior of the ignition device 101 is connected to the main combustion chamber 11 of the engine 10. After the fuel is ignited in the pre-combustion chamber 101b, the flame jet can enter the main combustion chamber 11 of the engine 10 from the pre-combustion chamber 101b to ignite the fuel in the main combustion chamber 11.

[0127] In some embodiments, at least a portion of the combustion chamber 200a is configured as a main combustion chamber 11, which is connected to the pre-combustion chamber 101b. Specifically, the main combustion chamber 11 is formed, for example, inside the engine 10. Fuel enters the main combustion chamber 11 and undergoes combustion. The energy converted during combustion can be output externally through other parts of the engine.

[0128] In this application, the ignition device 101 serves as the structure for igniting fuel and is used to form a pre-combustion chamber 101b. As an exemplary description of the specific structure of the ignition device 101 itself, in some embodiments, the pre-combustion chamber 101b is connected to the atomizing device 102 via an output flow path 112 to allow atomized fuel to enter. More specifically, refer to... Figure 1 and Figure 2 As shown, the ignition device 101 includes a pre-combustion chamber 101a. The pre-combustion chamber 101a forms the aforementioned pre-combustion chamber 101b, meaning the pre-combustion chamber 101a has a pre-combustion chamber 101b communicating with the main combustion chamber 11 of the engine 10. This pre-combustion chamber 101a, or other pre-combustion chamber 101b formed in other forms, is fixed to the cylinder head 12, for example, by a threaded connection. The pre-combustion chamber 101a, or other pre-combustion chamber 101b formed in other forms, can also be integrally formed with the cylinder head 12, so that the ignition device 101 is integrated with the engine 10. An atomizing device 102 is connected to the pre-combustion chamber 101b through an output flow path 112 to deliver atomized fuel to the pre-combustion chamber 101b. Specifically, after flowing out of the atomizing device 102, the fuel passes through the output flow path 112 on the cylinder head 12, is fully atomized, and then enters the pre-combustion chamber 101b.

[0129] In a more specific plan, refer to Figure 1 and Figure 2As shown, the pre-combustion chamber 101b is provided with a connecting channel 101c. In a specific embodiment, for example, the connecting channel 101c is formed on the pre-combustion chamber 101a. This connecting channel 101c connects the output flow path 112 and the pre-combustion chamber 101b; the connecting channel 101c connects to the main combustion chamber 11 of the engine 10 through the pre-combustion chamber 101b. In a more specific embodiment, the connecting channel 101c is, for example, a through hole formed on the pre-combustion chamber 101a, which connects to the connecting channel and the pre-combustion chamber 101b, and the through hole is surrounded by the cylinder head 12, so that the through hole can only connect to the main combustion chamber 11 of the engine 10 through the pre-combustion chamber 101b. On the one hand, this allows fuel to flow to the pre-combustion chamber, and on the other hand, it prevents the atomized fuel flowing out from the atomizing device 102 from bypassing the pre-combustion chamber 101b and directly entering the main combustion chamber 11, so as to fully mix the atomized fuel into the pre-combustion chamber 101b for combustion.

[0130] In some embodiments, refer to Figure 1 and Figure 2 As shown, the ignition device 101 further includes a spark plug 101d. The spark plug 101d is at least partially disposed within the pre-combustion chamber 101b for igniting the fuel within the pre-combustion chamber 101b. By disposing of the spark plug 101d within the pre-combustion chamber 101b, the fuel in the pre-combustion chamber 101b is ignited when the spark plug 101d is in operation.

[0131] The preceding text mainly described the fuel supply method from the ignition system 200 to the engine 10. Since the fuel needs to be mixed with air before combustion in the engine 10, the ignition system 200 of this application further includes an air supply device 116 to supply air to the main combustion chamber 11, so that the air mixes with the fuel and burns within the main combustion chamber 11.

[0132] In some embodiments, refer to Figure 1 As shown, the air supply device 116 includes a throttle valve 114. The throttle valve 114 is connected to the main combustion chamber 11 to control the flow of external air into the main combustion chamber 11. The external air referred to here means the air flowing from outside the main combustion chamber 11 through the throttle valve 114 into the main combustion chamber 11. During different strokes of the engine 10, the throttle valve 114 controls the flow of air into the main combustion chamber 11 to ensure the normal operation of the engine 10. The specific structure of the throttle valve 114 will not be described in detail here.

[0133] In some embodiments, refer to Figure 1 As shown, the air supply device 116 also includes an air filter 115. The air filter 115 is used to filter the external air flowing into the main combustion chamber 11.

[0134] In some embodiments, refer to Figure 1As shown, the air supply device 116 includes an intake manifold 113. The intake manifold 113 is connected to the main combustion chamber 11 to allow air to flow from the intake manifold 113 to the main combustion chamber 11. Specifically, the intake manifold 113 is connected to the main combustion chamber 11 of the engine 10 to supply air to the main combustion chamber 11 of the engine 10; that is, the intake manifold 113 connects to the air intake port of the main combustion chamber 11 of the engine 10, so that air enters the main combustion chamber 11 from the intake manifold 113 and mixes with fuel to achieve fuel combustion. For a multi-cylinder engine 10, the intake manifold 113 is provided to deliver air to multiple different main combustion chambers 11 of the engine 10.

[0135] In some embodiments, the throttle valve 114 is connected between the air filter 115 and the intake manifold 113, allowing the air filter 115 to filter the air flowing into the intake manifold 113. The throttle valve 114, connected between the air filter 115 and the intake manifold 113, not only utilizes the air filter 115 to filter dust and other impurities from the air, but also prevents the air filter 115 from directly contacting the high-temperature gases in the main combustion chamber 11 when the throttle valve 114 blocks air from entering the main combustion chamber 11, thus ensuring the long-term stable operation of the air filter 115. The specific structure of the air filter 115 will not be described in detail here.

[0136] According to the third aspect of this application, referring to Figure 4 As shown, a vehicle 1 is also provided, including the aforementioned atomizing system 100, or including the aforementioned ignition system 200. The vehicle 1 possesses the beneficial effects of the aforementioned ignition system 200, which will not be elaborated further here. Specifically, the ignition system 200 is used to integrate with the engine 10 of the vehicle 1, or the engine 10 of the vehicle 1 is part of the ignition system 200.

[0137] The vehicle 1 can be a gasoline-powered vehicle, a plug-in hybrid vehicle, etc., and this application does not make any specific limitation in this regard.
