Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle technology, specifically to a motorcycle with an energy-saving and emission-reducing power mechanism. Background Technology
[0002] In motorcycle operation, efficient fuel atomization and precise fuel supply are key factors affecting engine power performance and combustion efficiency. The working cycle of a motorcycle engine typically includes four steps: intake, compression, combustion, and exhaust. The fuel injector, as the core component of the fuel supply system, directly determines the quality of the fuel-air mixture, thus affecting the engine's power output and emissions. Existing fuel injectors mostly use a single atomizing orifice, resulting in limited atomization space, large and unevenly distributed fuel particles, and insufficient mixing with air, leading to low fuel utilization, incomplete combustion, and high pollutant emissions. This paper designs a motorcycle with an energy-saving and emission-reducing power mechanism to address these problems. Utility Model Content
[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0004] To address the technical problems mentioned in the background section, some embodiments of this application provide a motorcycle with an energy-saving and emission-reducing power mechanism, including a motorcycle body, an engine fixedly mounted on the motorcycle body, and a fuel injector fixedly mounted on the engine. The fuel injector includes a housing, an oil inlet on the housing, a filter screen at the oil inlet, an oil inlet channel inside the housing, a terminal block fixedly mounted on the housing, an electromagnetic coil inside the housing, an atomizing mechanism on the housing, and a fuel replenishment mechanism on the housing. The atomizing mechanism includes a valve body fixedly mounted inside the housing, an armature movably mounted on the valve body, a closing spring fixed at both ends on the housing and the armature respectively, an oil groove on the valve body, a rounded corner at the edge of the oil groove, a baffle movably mounted inside the oil groove, a needle valve fixedly mounted on the armature, a needle shaft fixedly mounted on the needle valve, multiple oil outlet holes on the housing, an atomizing chamber on the housing, and multiple atomizing plates fixedly mounted inside the atomizing chamber. The thickness of the baffle is less than the height of the oil groove.
[0005] Specifically, one end of each of the atomizing plates is fixedly disposed on the atomizing chamber.
[0006] Specifically, the other ends of the multiple atomizing plates are all inclined toward the central axis of the atomizing cavity and close to each other.
[0007] Specifically, the angle between the atomizing plate and the central axis of the atomizing cavity is 15-30°.
[0008] Specifically, the oil replenishment mechanism includes an oil pipe fixed on the housing, a V-shaped groove on the oil pipe, a stop block movable in the V-shaped groove, a cover plate fixed at one end of the oil pipe, a tension spring fixed at both ends of the stop block and the cover plate respectively, and multiple oil replenishment holes on the cover plate.
[0009] Specifically, the oil pipe is fixedly mounted on the valve body.
[0010] Specifically, the oil pipe is connected to the oil inlet channel.
[0011] The beneficial effects of this utility model are:
[0012] (1) Multiple atomizing plates form a conical flow guide space, which breaks the fuel into multiple fine streams through mechanical cutting and impact. The flow guide groove is formed between multiple atomizing plates, which forces the fuel to be diverted, achieving finer atomization, significantly improving the uniformity of fuel-air mixing. Fine atomization enables the fuel to burn quickly and completely in the combustion chamber, reducing local rich / lean fuel phenomena, improving combustion efficiency and fuel utilization, reducing the emission of hydrocarbons and particulate matter, and achieving energy saving and emission reduction.
[0013] (2) The fuel replenishment mechanism uses the increased air pressure during the engine compression stroke as a power source to release the fuel stored in the fuel line. The fuel replenished during the compression stage forms a turbulent mixture with the high-pressure air, which makes up for the possible insufficient mixing during the intake stage, optimizes the air-fuel ratio in the combustion chamber, and improves combustion efficiency and fuel utilization.

[0029] Reference Figures 1-7As shown, the present invention discloses a motorcycle with an energy-saving and emission-reducing power mechanism, comprising a motorcycle body 10, an engine 11 fixedly mounted on the motorcycle body 10, and a fuel injector 1 fixedly mounted on the engine 11. The fuel injector 1 includes a housing 2, a fuel inlet 3 on the housing 2, a filter 4 at the fuel inlet 3, a fuel inlet channel 5 inside the housing 2, a terminal block 6 fixedly mounted on the housing 2, an electromagnetic coil 7 inside the housing 2, an atomizing mechanism 8 on the housing 2, and a fuel replenishment mechanism 9 on the housing 2. The atomizing mechanism 8 includes components fixedly mounted on the housing 2. The valve body 81 is movably mounted on the valve body 81, the closing spring 83 is fixed at both ends on the housing 2 and the armature 82 respectively, the oil groove 84 is mounted on the valve body 81, the rounded corner 85 is mounted on the edge of the oil groove 84, the baffle 86 is movably mounted in the oil groove 84, the needle valve 87 is fixed on the armature 82, the needle shaft 88 is fixed on the needle valve 87, the multiple oil outlet holes 89 are mounted on the housing 2, the atomizing chamber 891 is mounted on the housing 2, and the multiple atomizing plates 892 are fixed in the atomizing chamber 891; the thickness of the baffle 86 is less than the height of the oil groove 84.
[0030] Specifically, one end of each of the atomizing plates 892 is fixedly disposed on the atomizing chamber 891.
[0031] Specifically, the other ends of the plurality of atomizing plates 892 are all inclined toward the central axis of the atomizing cavity 891 and close to each other.
[0032] Specifically, the angle between the atomizing plate 892 and the central axis of the atomizing cavity 891 is 15-30°.
[0033] When a motorcycle is in motion, the engine 11 provides power by burning fuel, which can be summarized into four steps: intake, compression, combustion, and exhaust. During the intake process, the injector 1 injects fuel into the combustion chamber of the engine 11, mixes it with air, and after compression, it is ignited by the spark plug and then exhausted. The terminal block 6 of the injector 1 is connected to the electromagnetic coil 7. When the terminal block 6 is energized, the electromagnetic coil 7 becomes magnetic, attracting the armature 82 to move closer to the closing spring 83. Since the height of the baffle 86 is less than the height of the oil trough 84, when the armature 82 moves the baffle 86, the fuel passes through the oil trough 84. At the same time, the armature 82 moves the needle valve 87 and the needle shaft 88, and the fuel enters the atomization chamber 891. Multiple atomizing plates 892 are inclined and close to each other to form a conical atomization space. A guide groove is formed between the multiple atomizing plates 892, and the fuel is divided into multiple fine streams. When the fuel is sprayed out, it is cut and impacted by the atomizing plates 892, thereby achieving finer atomization and improving the atomization effect of the fuel.
[0034] Specifically, the oil replenishment mechanism 9 includes an oil pipe 91 fixedly mounted on the housing 2, a V-shaped groove 92 mounted on the oil pipe 91, a stop block 93 movably mounted in the V-shaped groove 92, a cover plate 94 fixedly mounted on one end of the oil pipe 91, a tension spring 95 fixedly mounted on the stop block 93 and the cover plate 94 at both ends respectively, and a plurality of oil replenishment holes 96 mounted on the cover plate 94.
[0035] Specifically, the oil pipe 91 is fixedly mounted on the valve body 81.
[0036] Specifically, the oil pipe 91 is connected to the oil inlet channel 5.
[0037] During intake, some fuel enters the fuel line 91, but due to the action of the baffle 93, the fuel stays in the fuel line 91. When the compression step begins, the air is compressed, the air pressure increases, and the baffle 93 moves in the V-groove 92. The fuel is then sprayed out from the fuel line 91 and further mixed with the air to improve combustion efficiency.
[0038] In summary, multiple atomizing plates 892 form a conical flow-guiding space, breaking the fuel into multiple fine streams through mechanical cutting and impact. The flow-guiding channels between the multiple atomizing plates 892 force fuel diversion, achieving finer atomization and significantly improving the uniformity of fuel-air mixing. This fine atomization allows for rapid and complete combustion of fuel in the combustion chamber, reducing localized rich / lean fuel phenomena, improving combustion efficiency and fuel utilization, and reducing hydrocarbon and particulate emissions, thus achieving energy conservation and emission reduction. The fuel replenishment mechanism 9 utilizes the increased air pressure during the engine 11's compression stroke as a power source to release fuel stored in the fuel line 91. The fuel replenished during the compression stage forms a turbulent mixture with the high-pressure air, compensating for any insufficient mixing during the intake stage, optimizing the air-fuel ratio in the combustion chamber, and improving combustion efficiency and fuel utilization. Using a fuel injector with the above structure on a motorcycle can improve fuel utilization and reduce pollutant emissions.
