The application of industrial borescope in the treatment of automobile carbon deposition.
After a car has been driven for a period of time, certain deposits will form in the fuel system. These sticky deposits turn into hard carbon deposits on fuel injectors, intake valves, combustion chambers, and more. The formation of deposits is directly related to the fuel of automobiles: First, because gasoline itself contains colloids, impurities, or dust, impurities, etc. brought in during storage and transportation, sludge-like deposits are formed in the fuel tank and fuel inlet. The second is that unstable components such as olefins in gasoline undergo oxidative polymerization at a certain temperature to form a colloidal, resinous viscous substance. In addition, cars are often at low and idling speeds, exacerbating the formation and accumulation of these deposits.
The dangers of carbon deposition:
1. Sediments will block the pinholes and valve holes of the fuel injection nozzle, affecting the working performance of the precision components of the electronic injection system, thereby deforming the fuel injection and reducing its normal flow, resulting in a decline in power performance; if it is a carburetor engine, Sediments will accumulate in the carburetor, especially near the oil orifice, which can lead to unstable engine idling, easy flameout, and increased fuel consumption.
2. Deposits will form carbon deposits on the intake valve, causing it to close loosely, and the cylinder pressure of the combustion chamber will drop, resulting in unstable engine operation, increased fuel consumption, and environmental deterioration accompanied by exhaust emissions.
3. Deposits can form hard carbon deposits on piston crowns and cylinder heads, etc. Due to the high heat capacity and poor thermal conductivity of carbon deposits, it is easy to cause local overheating of the combustion chamber, gasoline pre-ignition and other failures such as engine knocking; at the same time, with the continuous accumulation of carbon deposits, the volume of the combustion chamber will decrease and the compression ratio of the engine will increase. The increase in the demand for gasoline octane number will lead to an increase in fuel consumption; in particular, the emission of HC and NOx in the exhaust will increase, and the life of the three-way catalytic purifier will be shortened.
What is the application of industrial borescope in inspecting and removing carbon deposits?
Industrial borescopes can be used to check the wear, coke deposits, blockages, etc. of engines, gearboxes, mufflers, fuel pipes, etc., and have been widely used in the auto repair industry. In the cleaning and maintenance of automobile engines, industrial borescopes are also a good helper. Before cleaning the engine, observe the carbon deposition inside the engine with an borescope, and take pictures. After the engine is cleaned, observe and take pictures. The images observed before and after cleaning are then compared, allowing customers to have an intuitive comparison of cleaning results.
