Description

Technical Field

[0001] This utility model relates to the field of carbon remover testing, specifically a device for testing the dispersibility of engine carbon remover. Background Technology

[0002] Engine carbon remover is a chemical preparation used to clean and remove carbon deposits inside automobile engines. It primarily works by dissolving, dispersing, or decomposing carbon deposits within the engine, restoring engine performance and extending its lifespan. The active ingredients in the carbon remover (such as polyetheramine and polyisobutyleneamine) can penetrate the porous structure of the carbon deposits, weakening their adhesion to the metal surface, causing them to gradually soften and detach. The detached carbon particles are dispersed in the engine oil or fuel by the carbon remover, filtered through a filter, or discharged with exhaust gases, preventing secondary deposition. Some carbon removers contain antioxidants and anti-corrosion components, which can form a protective film on the metal surface, reducing the formation of new carbon deposits. For example, fuel carbon removers mainly consist of polyetheramine (PEA), polyisobutyleneamine (PIBA), methanol, and detergents, and are used to clean the fuel system (fuel injectors, combustion chamber, valves, etc.). The dispersibility of carbon remover needs to be tested before leaving the factory. Its dispersibility includes oil solubility, dispersion index and coking plate test. Taking the oil solubility test as an example, the specific test method is as follows: mix the carbon remover with lubricating oil in a certain proportion (such as 5%), stir evenly and observe the transparency of the solution; let it stand for 24 hours. If the solution does not separate, precipitate or become turbid, it is considered to have good oil solubility. In the actual experiment, when the decarbonizing agent was poured into the test tube for testing, it was impossible to simulate the shear force and turbulence inside the engine. Then, to observe the stability of the mixture under dynamic conditions, the test results may show natural stratification due to gravity, rather than the true oil solubility of the decarbonizing agent. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the dispersibility of engine carbon remover, so as to solve the defects mentioned in the background art.

[0004] To achieve the above objectives, a dispersibility testing device for engine carbon remover is provided, comprising a testing platform, an oscillating seat movably mounted on the upper side of the testing platform, a tube positioning seat fixedly disposed on the surface of the oscillating seat, a dispersibility testing tube inserted inside the tube positioning seat, a connecting seat fixedly disposed at the end of the oscillating seat, a rocker arm movably mounted inside the connecting seat via a pin, a turntable movably mounted at the end of the rocker arm away from the connecting seat via a pin, a rotating shaft mounted on the lower side of the center of the turntable, a drive motor mounted below the turntable, and the output shaft of the drive motor being fixed to the rotating shaft of the turntable.

[0005] Preferably, a support base is fixedly provided on both sides of the bottom of the testing table. The support base is L-shaped in cross section, and a rubber pad is fixedly provided at the bottom of the support base.

[0006] Preferably, the upper side of the testing platform is provided with a receiving groove, the inner wall of the receiving groove is provided with a guide rail, and both ends of the vibration seat are fixedly provided with guide blocks, the dimensions of the guide blocks and the guide rails are matched.

[0007] Preferably, the oscillating seat is rectangular and is slidably disposed inside the guide rail via guide blocks at both ends. The guide blocks and the guide rail have circular cross-sections.

[0008] Preferably, the oscillating seat is driven to reciprocate laterally via a connecting seat, rocker arm, turntable, and drive motor, with the drive motor fixedly connected to the side wall of the support seat via a base.

[0009] Preferably, the tube positioning seat is cylindrical, and eight sets of dispersion test tubes are evenly inserted on the tube positioning seat. The eight sets of dispersion test tubes are distributed in a circular pattern, and four sets of tube positioning seats are linearly and evenly arranged on the surface of the oscillating seat.

[0010] Preferably, the tube positioning seat includes a limiting plate, a limiting through hole, a support column, an insert plate, and an insert hole. The insert plate is fixedly installed on the surface of the vibrating seat. The limiting plate is fixedly installed on the surface of the insert plate through the support column.

[0014] Please see Figure 1-5 This utility model provides a device for detecting the dispersibility of engine decarbonizing agent, including a test platform 1. A vibrating seat 3 is movably mounted on the upper side of the test platform 1. A tube positioning seat 9 is fixedly disposed on the surface of the vibrating seat 3. A dispersibility test tube 8 is inserted inside the tube positioning seat 9. A connecting seat 4 is fixedly disposed at the end of the vibrating seat 3. A rocker arm 5 is movably mounted inside the connecting seat 4 via a pin. A turntable 6 is movably mounted at the end of the rocker arm 5 away from the connecting seat 4 via a pin. A rotating shaft is mounted on the lower side of the middle of the turntable 6. A drive motor 7 is mounted below the turntable 6. The output shaft of the drive motor 7 is fixed to the rotating shaft of the turntable 6.

[0015] Working principle: In actual use, the decarbonizing agent is mixed with lubricating oil in a certain proportion, such as 5%, inside the dispersibility test tube 8. Then, the external switch of the drive motor 7 is turned on, and the output shaft of the drive motor 7 drives the turntable 6 to rotate. The turntable 6 drives the connecting seat 4 and the oscillating seat 3 to move laterally and reciprocally through the rocker arm 5. This causes the four sets of tube positioning seats 9 and the large number of dispersibility test tubes 8 on them to oscillate back and forth, simulating the shear force and turbulence of the decarbonizing agent and lubricating oil inside the engine. The stability of the mixture under dynamic conditions is observed, avoiding the result of natural stratification due to gravity instead of the true oil solubility of the decarbonizing agent, thus improving the accuracy of the decarbonizing agent dispersibility test. The tube positioning seat 9 reciprocates, mechanically simulating the real shear force and turbulence environment inside the engine. This effectively reproduces the mixing state of the decarbonizing agent and lubricating oil under dynamic operating conditions, avoiding errors caused by gravity stratification in static testing. The coordinated design of the rocker arm 5, turntable 6, and oscillating seat 3 enables synchronous lateral reciprocating oscillation of multiple test tubes, improving testing efficiency and disrupting natural stratification through continuous mechanical force, forcing the mixture to expose its true dispersion stability in motion. The drive motor 7 precisely controls the oscillation frequency, ensuring that the simulated conditions closely approximate the hydrodynamic characteristics of an actual engine, directly reflecting the decarbonizing agent's anti-settling ability and homogeneity retention in the oil. The design of four sets of tube positioning seats 9 allows for batch parallel experiments on decarbonizing agents of different brands or specifications, reducing human error and ensuring strong data comparability. The overall solution replaces static observation with dynamic testing, significantly improving the accuracy of evaluating the oil solubility, dispersibility, and durability of the decarbonizing agent, providing more reliable experimental evidence for product performance verification.
