Abstract
Description
Technical Field
[0001] The utility model relates to a carbon deposit cleaning technology for automobile engines, in particular to an intelligent dynamic carbon removal device for carbon deposits in engine cylinders. Background Art
[0002] When a vehicle has a carbon deposit problem, some adverse effects will occur. First of all, carbon deposits will reduce the efficiency of the engine, resulting in insufficient power and increased fuel consumption. Carbon deposits will also affect the working stability of the engine, and it is easy to have problems such as shaking and stalling, which will bring hidden dangers to driving safety. In addition, carbon deposits are also prone to cause problems such as engine overheating and detonation, further reducing the life of the engine and increasing maintenance costs. In order to solve the problem of carbon deposits in cars, car owners need to pay attention to daily car use habits, avoid bad driving habits, and choose fuel reasonably. It is also very important to regularly perform engine maintenance and cleaning, which is also an effective means to prevent carbon deposits. After the car has traveled a certain mileage, clean and maintain the inside of the engine, remove carbon deposits in time, and ensure the normal operation of the car.
[0003] Currently, the mainstream methods for removing engine carbon deposits include additive cleaning, bottle cleaning (also known as dynamic carbon removal) and disassembly cleaning.
[0004] 1. Disassembly and cleaning: Disassembly and cleaning means removing the parts of the engine with carbon deposits, including the engine, and completely disassembling and cleaning them. Although this method has the best cleaning effect, due to the large workload, time-consuming and labor-intensive, 4S stores generally recommend not to use the disassembly and cleaning method as much as possible. Moreover, disassembling the engine will affect the service life of the engine. For example, many parameters of the engines of Japanese cars are adjusted before leaving the factory. If you really have to disassemble the engine for repair, even if it is repaired, the future car experience will definitely be greatly reduced, and serious failures will occur continuously. Therefore, it is best not to disassemble Japanese engines. Similarly, other higher-end engines are best not to be disassembled.
[0005] 2. Additive cleaning: Additive cleaning is to add PNF additive directly into the fuel tank and mix it with the fuel. When the vehicle is running, the PNF additive will enter the combustion chamber along with the fuel to clean the carbon deposits inside the engine to a certain extent. The principle of removing carbon deposits in this type of operation is the same as dynamic carbon removal, but such an operation generally consumes several boxes of oil (including gasoline or diesel), and it needs to be added regularly, which takes too long. In addition, because the car owner does not have professional equipment to test, the result cannot be judged at all. To confirm, it must be checked at the auto repair shop. Therefore, in practice, many car owners do not agree with this method, and most 4S stores do not recommend this method.
[0006] 3. Dynamic carbon removal (also known as hanging bottle cleaning): Hanging bottle cleaning is a cleaning method that does not require disassembly. It is also a cleaning method that 4S stores strongly recommend. This method is to set up a dynamic carbon removal machine outside the oil pipeline. There is a stainless steel tank (hanging bottle) in the carbon removal machine. The stainless steel tank contains a mixed liquid of special cleaning liquid and gasoline in proportion. Then, a pressurized gas is pumped in with an air pump to replace the pressure supplied by the fuel pump. The stainless steel tank replaces the fuel tank to deliver the mixed liquid to the engine. When the engine is idling, the piston moves up and down to use the liquid to achieve carbon removal. However, there are some problems with the equipment and methods of this method. (1) The existing dynamic carbon removal equipment is relatively simple. Its operation method must first mix the liquid and gasoline in a certain proportion in the cylinder (hanging bottle) of the dynamic carbon removal machine. The problem here is that gasoline itself is a dangerous controlled product that is flammable and explosive. The operation of mixing liquid and gasoline in the air is relatively risky. Moreover, as a controlled product, gasoline cannot be stored without special qualifications. Therefore, according to regulations, even auto repair shops cannot store gasoline. Therefore, the mixing of cleaning liquid and gasoline when using a dynamic carbon removal machine actually violates the relevant safety management regulations. (2) When using this method and equipment, 2-3 atmospheres of pressure are added to the steel tank (hanging bottle) containing the mixed liquid, and the mixed liquid is transported to the engine with a stainless steel tank instead of the oil tank. The problem here is: because the pressure provided by the oil tank pump when the engine is started is different for different types of cars, if the pressure provided by the steel tank is too small at this time, the engine will extinguish and cannot be started; if the pressure provided is too large, the spark plug will be flooded and the engine will also not start. Therefore, the existing dynamic carbon removal often has the problem of flameout and inability to start. Utility Model Content
[0007] The technical purpose of the utility model is to provide an intelligent dynamic carbon removal device for carbon deposits in engine cylinders, which can realize the rapid, efficient and safe direct mixing of fuel and cleaning liquid in the automobile tank in the oil circuit and provide the mixture to the engine through the fuel inlet of the engine oil rail. The safety of the overall operation process is very high, and the problem of non-compliant storage of gasoline in auto repair shops is avoided. In particular, it can realize rapid, accurate and convenient regulation of the ratio of fuel and cleaning liquid, and can adjust the ratio of liquid and fuel at any time according to the cleaning progress, severity of carbon deposits and the like while cleaning carbon deposits, thereby improving the cleaning efficiency. At the same time, the hydraulic pressure of the mixed liquid provided to the engine can be adjusted at any time, avoiding the problem of easy engine stalling caused by unreasonable setting of the air supply pressure of the stainless steel tank in the prior art.
[0008] The technical solution adopted by the utility model to achieve the above technical purpose is: an intelligent engine cylinder carbon deposit dynamic removal equipment, including a shell and a steel tank in the shell, the top of the steel tank is provided with a liquid injection port and an air inlet, and the bottom of the steel tank is provided with a liquid outlet; the liquid injection port is installed through the top of the shell and is equipped with a sealing cover; the air inlet is connected to an external air source device through a pressure regulating valve; the liquid outlet is connected to a one-way valve and a fuel injector B in sequence, and the fuel injector B is divided into two paths through a three-way interface, one of which is connected to the fuel inlet of the engine oil rail through a hydraulic gauge 2 and a ball valve switch 2 in sequence; the other is connected to the fuel tank oil pump through a fuel injector A, a hydraulic gauge 1, and a ball valve switch 1 in sequence; the fuel injector A is provided with a bypass, and a solenoid valve is provided on the bypass; a pressure relief branch is connected to the oil circuit between the fuel injector A and the hydraulic gauge 1, and a pressure relief valve is provided on the pressure relief branch, and the pressure relief valve is connected to an oil barrel; the steel tank is equipped with a device for displaying the liquid level; the fuel injector B and the fuel injector A and the solenoid valve are electrically connected to a control mainboard installed on the inner side of the top panel of the shell. (The text description has been adjusted, please take a look)
[0009] Furthermore, the hydraulic pressure gauge 2, the pressure regulating valve, and the air pressure gauge matching the pressure regulating valve described in the utility model are arranged on the panel of the housing.
[0010] Furthermore, the utility model provides a three-way air valve for exhausting air on the air path connecting the steel tank and the air source device, thereby avoiding the safety problems caused by exhausting air through the liquid injection port in the past.
[0011] Furthermore, the utility model can be equipped with a filter on the hydraulic pipeline between the fuel injector A and the fuel injector B connected in parallel and the hydraulic meter 2. The filter is installed on the panel of the housing, and the mixed particulate matter can be filtered out by the filter to avoid damage to the engine.
[0012] Furthermore, the utility model can install universal wheels and other traveling mechanisms at the bottom of the shell to improve the mobility of the equipment.
[0013] Furthermore, the utility model can be provided with a handle on the top of the shell for facilitating the movement and lifting of the device.
[0014] Furthermore, the liquid level observation device of the utility model is a transparent communicating tube, which is installed on the side wall of the shell and connected to the top and bottom of the steel tank through connecting pipes and joints; and a scale for comparing the liquid level height is provided on the side wall of the shell.
[0015] Furthermore, the control mainboard of the utility model adopts a microcontroller (single-chip computer) of model TYD-DISP (Ver1.2).
[0016] The principle and operation flow of the utility model are as follows: at the beginning, a certain amount of cleaning liquid should be added into the steel tank according to the cleaning requirements and the sealing cover should be covered. Then the oil pipeline connecting the oil rail and the oil pump of the automobile engine should be removed, and the utility model product should be connected between the fuel inlet of the engine oil rail and the oil pump of the fuel tank by using the matching joint. Then the ball valve switch 1, the solenoid valve and the ball valve switch 2 are all opened to connect the oil circuit between the fuel tank and the engine. At this time, the oil pump works to inject fuel into the engine, and the engine starts normally. At the same time, the hydraulic meter 1 can accurately record the pressure of the oil pump supply required for the car to start. Then turn on the air source device to pressurize the gas into the steel tank, and adjust the air pressure value through the pressure regulating valve so that the pressure in the steel tank reaches a pressure close to the oil supply pressure required for the car to start. Then turn on the cleaning function key on the equipment operation panel, control the solenoid valve to stop working through the control mainboard, control the injector A and injector B to open at the same time through the control mainboard, control the injection pulse frequency of injector A and injector B to adjust the output of injector A and injector B to different injection amounts, so that the ratio of cleaning liquid and fuel reaches the preset requirements, and through fine-tuning, reduce or increase the injection amount of injector A and injector B at the same time, and then adjust the size of the liquid pressure injected into the engine by the mixed liquid to keep it the same as the pressure of the oil pump supply required for the car to start (the control mainboard adopts a microcontroller and similar control method similar to the car driving computer, and its corresponding control principles and technologies are conventional means.) After the adjustment is in place, the mixed liquid of cleaning liquid and fuel is added to the engine to start the dynamic cleaning of carbon deposits in the engine cylinder. According to the severity of carbon deposits in the engine cylinder and the cleaning process, the adjustment of the proportion of cleaning liquid and fuel can be completed at any time, and carbon deposit cleaning can generally be completed in one to two hours. By observing the communicating vessel, pay attention to the reduction in the amount of cleaning liquid in the steel tank. When the cleaning liquid is basically used up, turn off the cleaning function key on the equipment operation panel in time, and control the nozzle A and the injector B to stop working at the same time through the control mainboard. At the same time, the solenoid valve is opened, and the air source device then closes the ball valve switch 1 and the ball valve switch 2 in time. The car is turned off and the engine is stopped to complete the carbon deposit cleaning work. If the cleaning is not in place, the cleaning liquid can be added and the above process can be repeated to clean the carbon deposits in the engine cylinder.
[0017] The beneficial effects of the utility model are as follows: the advantages of the utility model produced by the setting of the corresponding oil circuit and gas circuit in conjunction with the setting of the steel tank structure include:
[0018] Firstly, the fuel in the automobile tank and the cleaning liquid in the steel tank can be directly mixed in the oil circuit and transported to the engine for dynamic cleaning. During the whole process, the fuel will not leak into the air, which completely avoids the dangerous operation of mixing gasoline and liquid medicine in the air in the current existing technology, greatly improves safety, and also avoids the problem of illegal storage of gasoline in repair shops.
[0019] Secondly, the control mainboard can be used to control the simultaneous opening of injector A and injector B. By controlling the injection pulse frequency of injector A and injector B, injector A and injector B can be adjusted to output different injection amounts. The mixing ratio of cleaning liquid and fuel can be quickly completed to reach the preset requirements in the oil circuit. The injection amount of injector A and injector B can be reduced or increased at the same time through fine adjustment, thereby adjusting the hydraulic pressure of the mixed liquid injected into the engine. In conjunction with the settings of hydraulic gauge 1 and hydraulic gauge 2, the pressure of the mixed liquid is always kept consistent with the pressure of the oil pump supply required for the car to start. The advantages of the present invention are as follows: (1) it completely avoids the problem in the prior art that the pressure in the steel tank (also called hanging bottle) is simply set to a fixed value. Since the starting oil pressure of different cars is different, the pressure of the steel tank supplying oil to the engine is too low or too high, which makes it impossible to start the car normally and causes the car to stall frequently; (2) because the ratio of fuel and cleaning liquid can be quickly, accurately and conveniently adjusted at any time, the ratio of liquid and fuel can be adjusted according to the cleaning progress, the severity of carbon deposits, etc. while cleaning carbon deposits to improve the cleaning efficiency;
[0020] Thirdly, the utility model arranges a three-way air valve on the gas path between the steel tank and the gas source device, so that when the dynamic decarbonization is completed, the pressure in the steel tank can be relieved. At this time, there is no need to open the liquid injection port to relieve the pressure, which avoids the danger of the operation. At this time, it is only necessary to close the gas supply of the gas source device, and the pressure regulating valve is not closed. At the same time, the three-way air valve is turned to another passage, the gas path between the steel tank and the gas source is closed, and the air pressure in the steel tank will be discharged from another passage interface of the three-way air valve, which is very safe.
[0021] Fourthly, the utility model provides a filter on the hydraulic pipeline between the fuel injector A and the fuel injector B connected in parallel and the hydraulic meter 2, so as to filter out particles that may be mixed in the mixed liquid due to improper operation, thereby avoiding damage to the engine.
[0022] Fifthly, the utility model can conveniently pay attention to the reduction of the amount of cleaning liquid in the steel tank through the arrangement of the observable communicating vessel. When the cleaning liquid is basically used up, the gas source device is promptly turned off and then the ball valve switch 1 and the ball valve switch 2 are properly closed. The car is turned off and the engine is stopped to complete the carbon deposit cleaning work. If the cleaning is not in place, the cleaning liquid can be supplemented and the above process can be repeated to clean the carbon deposits in the engine cylinder.
[0023] Sixthly, other structural designs of the present invention will also bring corresponding advantages to the present invention, for example, universal wheels can be installed at the bottom of the shell to improve the mobility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
