Description

Technical Field

[0001] This invention relates to the field of engine fuel system technology, specifically to a device for heating fuel by arranging an electric heating coil around the injector cylinder head bore seat. Background Technology

[0002] In recent years, in order to improve the fuel atomization efficiency and combustion performance of internal combustion engines, the operating temperature control of fuel injectors has become one of the hot issues in research and engineering optimization. As we all know, when fuel injectors work in low-temperature environments, fuel viscosity increases and atomization effect deteriorates, which can easily lead to problems such as difficulty in starting the engine, increased fuel consumption and worsened emissions. To this end, researchers have proposed a variety of active heating schemes in order to achieve rapid and uniform preheating at the injector port and improve atomization quality.

[0003] The article "An Internally Heated Tip Injector to Reduce HC Emissions During Cold Start" proposes an innovative internally heated tip injector design aimed at reducing hydrocarbon emissions during cold starts. This design effectively improves fuel evaporation efficiency in the intake manifold by heating the injector tip, thereby promoting more complete combustion and reducing harmful emissions. However, because heating is limited to the injector tip, the heating process is relatively slow and uneven. Specifically, the tip temperature rises rapidly, while areas closer to the injector fail to reach the required temperature quickly, resulting in a large temperature gradient. This not only affects the overall performance of the injector but also leads to unsatisfactory fuel atomization. This affects the complete evaporation of fuel and the combustion efficiency during cold starts. To solve these problems, existing technologies use electric heating rods to locally heat the injector body, thereby improving the stability of the injector under cold start conditions. This solution improves the working efficiency of the injector to a certain extent, especially in low-temperature environments, and helps to reduce HC emissions during cold starts. However, this heating device often requires drilling holes or custom structural parts in the cylinder head injector mounting area, making batch modifications or upgrades of old engines complex and costly. Furthermore, there are gaps between the heating element and the injector surface, resulting in low heat transfer efficiency and significant heat loss, which affects the heating effect and cannot meet the needs of users. Summary of the Invention

[0009] Preferably, the measuring component includes a fixing plate, two fixing plates are respectively fixedly connected to the front and rear sides of the top of the housing, and a temperature sensor is fixedly connected to one bottom end of the fixing plate.

[0010] Preferably, the thrust assembly includes grooves, and a plurality of grooves are respectively formed around the bottom inner side of the housing. A guide rod is fixedly connected to the inner side of the groove, and one end of the guide rod passes through the movable block.

[0011] Preferably, the actuating component includes a through groove, which is located in the lower right part of the housing. A toggle block is slidably connected to the inner side of the through groove, and the left end of the toggle block is fixedly connected to the movable ring.

[0012] Preferably, the mounting assembly includes a T-shaped groove, a plurality of T-shaped grooves are equidistantly formed on the top of the engine cylinder head, a sliding groove is formed on the inner side of the T-shaped groove, a limit block is fixedly connected to the front and rear sides of the movable seat, and the outer side of the sliding groove is slidably connected to the limit block.

[0016] This invention provides a device for heating fuel by arranging an electric heating coil around the cylinder head bore seat of the fuel injector.

[0017] It has the following beneficial effects:

[0018] 1. This invention monitors the injector temperature using a temperature sensor, controls the coil heating, and transfers heat to the injector surface through a thermally conductive silicone layer, raising its temperature to approximately 85 degrees Celsius within three seconds. This helps preheat the fuel, reduce viscosity, improve atomization quality, enhance fuel atomization and combustion efficiency in cold conditions, strengthen engine cold start stability, and reduce HC emissions. Furthermore, the 360-degree annular design of the heating structure avoids localized overheating, ensuring uniform heating and improving the heating effect of the device, thus meeting the needs of users.

[0019] 2. This invention uses a toggle block to rotate a movable ring. The rotation of the movable ring pushes the insertion post through the curved groove, causing the movable block to move and disengage the locking block from the slot, thereby disassembling the outer shell for easy maintenance and replacement of the heating coil. Furthermore, the return spring pushes the locking block to engage with the slot through the movable block, ensuring the outer shell is securely fixed, thus improving the ease of use of the device.

[0020] 3. When the present invention is in use, the engine will cause the outer casing to vibrate. The vibration of the outer casing is transmitted to the mounting base through the L-shaped plate, which in turn pushes the hollow plate to move. Since the hollow plate is connected to the energy-absorbing spring, the movement of the hollow plate will compress the energy-absorbing spring. The energy-absorbing spring contracts and absorbs the vibration energy, reducing the vibration of the outer casing and reducing the damage of engine vibration to the heating coil, thus improving the practicality of the device.

Detailed Implementation

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 , Figure 5 and Figure 6This invention provides a device for heating fuel by arranging an electric heating coil around the injector cylinder head seat, including an engine cylinder head 1. A plurality of standard injectors 5 are equidistantly arranged on the top of the engine cylinder head 1. A housing 6 is provided on the outer side of the standard injectors 5. A heating mechanism 2 is provided on the inner side of the housing 6. The heating mechanism 2 is used to facilitate heating of the standard injectors 5. A disassembly mechanism 3 is provided on the bottom inner side of the housing 6. The disassembly mechanism 3 is used to facilitate disassembly and maintenance of the electric heating coil. A shock-absorbing mechanism 4 is provided on the top of the housing 6. The shock-absorbing mechanism 4 is used to provide shock absorption.

[0033] Heating mechanism 2 includes a spiral outer ring 21, which is fixedly connected to the top inner side of the standard injector 5. A heating coil 22 is fixedly connected inside the spiral outer ring 21, which can generate heat. A thermally conductive silicone layer 23 is fixedly connected to the inner side of the spiral outer ring 21, and the thermally conductive silicone layer 23 is in contact with the standard injector 5. The thermally conductive silicone layer 23 can improve the heat transfer efficiency of the spiral outer ring 21. A measuring component 24 is provided on the top of the housing 6. The measuring component 24 includes a fixing plate 241. Two fixing plates 241 are fixedly connected to the front and rear sides of the top of the housing 6, respectively. A temperature sensor 242 is fixedly connected to one bottom end of the fixing plate 241. The temperature sensor 242 can be used to detect the outer temperature of the standard injector 5.

[0034] Specifically, during engine cold starts, the device monitors the temperature around the standard injector 5 in real time via temperature sensor 242. The system automatically adjusts the power supply current to the outer spiral ring 21, causing the heating coil 22 inside the outer spiral ring 21 to heat up. The thermally conductive silicone layer 23, which is in close contact with the inner side of the standard injector 5, transfers the generated heat to the surface of the standard injector 5, allowing the standard injector 5 to rapidly heat up from room temperature to approximately 85 degrees Celsius within three seconds. This preheats the fuel in the internal passages of the standard injector 5, reducing its viscosity and significantly improving atomization quality, thus helping to improve the fuel atomization effect in cold conditions. The improved air-fuel mixture combustion efficiency enhances engine stability during cold starts and effectively reduces HC emissions. Furthermore, the 360-degree annular heating structure avoids localized overheating or dead-angle heating issues common in traditional heating methods, ensuring uniform heating of the standard injector 5 and its surrounding area. The heating coil 22 also integrates temperature control and over-temperature protection functions. If the temperature exceeds the preset safety threshold, the system can automatically reduce the current or cut off the power supply to prevent overheating from causing device burnout or adversely affecting the lifespan of the injector, thus improving the heating effect of the device and meeting the user's needs.

[0035] Reference Figure 5 , Figure 7 and Figure 8The disassembly mechanism 3 includes a movable ring 31, which is rotatably connected to the lower inner part of the housing 6. Curved grooves 32 are formed around the bottom of the movable ring 31. A plug-in post 33 is slidably connected to the inner side of each curved groove 32. The movable ring 31 can push the plug-in post 33 to move through the curved grooves 32. A movable block 34 is fixedly connected to the bottom of the plug-in post 33. A locking block 35 is fixedly connected to one side of the movable block 34. The plug-in post 33 can push the locking block 35 to move through the movable block 34. A slot 36 is formed on the lower outer part of the standard injector 5. The movable block 34 engages with the slot 36 to fix the housing 6. A thrust assembly 37 is provided on the bottom inner side of the standard injector 5, and a toggle assembly 38 is provided on the lower right side of the housing 6. The thrust assembly 37 includes a groove 37. 1. Multiple grooves 371 are respectively formed around the bottom inner side of the outer casing 6. A guide rod 372 is fixedly connected to the inner side of the groove 371. One end of the guide rod 372 passes through the movable block 34. The movable block 34 can slide on the outer side of the guide rod 372. The actuating component 38 includes a through groove 381, which is formed in the lower right side of the outer casing 6. A toggle block 382 is slidably connected to the inner side of the through groove 381. The left end of the toggle block 382 is fixedly connected to the movable ring 31. The toggle block 382 will drive the movable ring 31 to rotate. The thrust component 37 also includes a return spring 373, which is set on the outer side of the guide rod 372. One end of the return spring 373 is fixedly connected to the movable block 34. The return spring 373 can push the locking block 35 to engage with the locking groove 36 through the movable block 34.

[0036] Specifically, when the heating coil 22 needs to be disassembled and replaced, the toggle block 382 is moved. When the toggle block 382 is moved, it will drive the movable ring 31 to rotate. During the rotation, the movable ring 31 can push the plug post 33 to move through the curved groove 32. The plug post 33 will drive the movable block 34 to move. The movement of the movable block 34 will further cause the locking block 35 to disengage from the original locking state with the slot 36, so that the outer shell 6 can be easily disassembled, thus providing convenience for the maintenance and replacement of the heating coil 22. In addition, the return spring 373 pushes the locking block 35 through the movement of the movable block 34 to ensure that the locking block 35 can be tightly locked with the slot 36, ensuring that the outer shell 6 can be firmly fixed after reassembly, improving the ease of use of the device.

[0037] Reference Figure 2 , Figure 4 and Figure 9The shock absorption mechanism 4 includes two L-shaped plates 41, which are fixedly connected to the top left and right sides of the outer casing 6, respectively. A mounting base 42 is fixedly connected to the top inner side of each L-shaped plate 41. The L-shaped plates 41 cause the mounting base 42 to vibrate. A hollow plate 43 is rotatably connected to the bottom of the mounting base 42. When the mounting base 42 vibrates, it causes the hollow plate 43 to move. An energy-absorbing spring 44 is fixedly connected to the inner side of the hollow plate 43. A sliding rod 45 is fixedly connected to the bottom end of the energy-absorbing spring 44. The energy-absorbing spring 44 can absorb... The thrust generated by vibration, the bottom end of the slide bar 45 is rotatably connected to the movable seat 46, the top of the engine cylinder head 1 is provided with the mounting component 47, the mounting component 47 includes a T-shaped groove 471, multiple T-shaped grooves 471 are equidistantly opened on the top of the engine cylinder head 1, the inner side of the T-shaped groove 471 is provided with a sliding groove 472, the front and rear sides of the movable seat 46 are fixedly connected with the limiting block 473, the outer side of the sliding groove 472 is slidably connected to the limiting block 473, the sliding groove 472 facilitates the installation of the movable seat 46 by the staff;

[0038] Specifically, vibrations are generated during engine operation, and these vibrations are directly transmitted to the outer casing 6, causing the outer casing 6 to vibrate accordingly. The outer casing 6, through the L-shaped plate 41, drives the mounting base 42 to vibrate. When the mounting base 42 vibrates, it further pushes the hollow plate 43 to move. The hollow plate 43 is connected to the slide rod 45 through an energy-absorbing spring 44. Therefore, when the hollow plate 43 moves, the energy-absorbing spring 44 is compressed. The compressed energy-absorbing spring 44 absorbs the energy generated by the vibration of the mounting base 42. In this way, the energy-absorbing spring 44 can effectively reduce the vibration intensity borne by the outer casing 6, thereby significantly reducing the damage to the heating coil 22 caused by engine vibration and improving the practicality of the device.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The heating mechanism 2 also includes a high-pressure oil rail 25, which is connected to the top of the standard injector 5 and is used to connect to an external oil supply pipeline. The bottom of the standard injector 5 is connected to an oil nozzle 26.

[0040] Specifically, the standard injector 5 can be connected to an external fuel supply line via the high-pressure fuel rail 25, and the injector 26 is used to inject fuel into the engine.

[0041] Reference Figure 5 The heating mechanism 2 also includes a connecting pipe 27, which is fixedly connected to the front side of the standard injector 5. The connecting pipe 27 is used to connect the control wiring harness. The inner size of the thermally conductive silicone layer 23 matches the size of the standard injector 5.

[0042] Specifically, the standard injector 5 is connected to an external device via the connecting pipe 27. The inner dimensions of the thermally conductive silicone layer 23 match the dimensions of the standard injector 5, which can improve the heat transfer efficiency.

[0043] Working principle: When the engine is cold-started, the device monitors the real-time temperature around the standard injector 5 through the temperature sensor 242, automatically adjusts the power supply current to the spiral outer ring 21, controls the heating coil 22 inside to heat up, and transfers the heat to the surface of the standard injector 5 through the thermally conductive silicone layer 23 that is in close contact with the outer wall of the standard injector 5. This causes the standard injector 5 to heat up from room temperature to about 85 degrees Celsius within three seconds, thereby preheating the fuel in the internal channel of the standard injector 5, reducing its viscosity, improving its atomization quality, thereby improving the atomization of fuel and the combustion efficiency of the air-fuel mixture in the cold state, improving the stability of the engine cold start and reducing HC emissions. Because the heating structure is a 360-degree ring, it avoids the problems of local overheating or dead zone heating that exist in traditional heating methods, and achieves uniform heating of the outside and adjacent areas of the standard injector 5. In addition, the heating coil 22 integrates temperature control and over-temperature protection functions. Once the temperature exceeds the set threshold, it can automatically reduce the current or cut off the power to prevent overheating and damage to the device or affect the life of the injector.

[0044] Furthermore, when it is necessary to disassemble and replace the heating coil 22, the toggle block 382 is moved, which will drive the movable ring 31 to rotate. When the movable ring 31 rotates, it can push the plug post 33 to move through the curved groove 32. The plug post 33 can then drive the movable block 34 to move. The movable block 34 will then drive the locking block 35 to disengage from the locking state of the locking groove 36, thereby making it easy to disassemble the outer shell 6 and facilitate the maintenance and replacement of the heating coil 22. In addition, the return spring 373 can push the locking block 35 to move through the movable block 34, so that the locking block 35 is always locked with the locking groove 36, thereby ensuring that the outer shell 6 is firmly fixed.

[0045] Finally, when using this device, the engine will vibrate during operation, and the outer casing 6 will vibrate accordingly. When the outer casing 6 vibrates, it can drive the mounting base 42 to vibrate through the L-shaped plate 41. When the mounting base 42 vibrates, it will push the hollow plate 43 to move. Since the slide rod 45 is connected to the hollow plate 43 through the energy-absorbing spring 44, the hollow plate 43 will compress the energy-absorbing spring 44 when it moves. The energy-absorbing spring 44 will then contract and absorb the thrust generated by the vibration of the mounting base 42, which can reduce the vibration of the outer casing 6 and thus reduce the damage to the heating coil 22 caused by engine vibration.
