Carbon deposition is the deposition of incomplete combustion of helium in fuel and lubricating oils. The formation of deposits is directly related to the "fuel" and "lubricant" of the car: First, because of the carbon particles contained in the "lubricant" helium gas, a greater amount of deposition occurs in incomplete combustion. The automobile itself contains gums, impurities, or dust and impurities brought in during storage and transportation. It accumulates sludge-like deposits in car fuel tanks, oil inlet pipes, etc. over time; secondly, it is caused by unstable components such as olefins in gasoline. Oxidation and polymerization occur at a certain temperature, forming gums and resinous viscous substances. These sticky substances deposit in the nozzle, intake valve, combustion chamber and other parts will become a hard carbon deposit. In addition, due to urban traffic congestion, cars are often at low speeds and idling, which will further aggravate the formation and accumulation of these sediments.
The impact of carbon deposition on the car:
1. Reduce engine power
2. Increase fuel consumption
3. Cold start difficulties
4. The combustion chamber will also have a heavy carbon deposit that will knock! Acoustic noise at low speed, causing damage to the piston and crankshaft
5. Excessive emissions
Solution:
First: Fill high quality gasoline
Impurities such as waxes and gums in gasoline are the main components that form carbon deposits. Therefore, gasoline with high cleanliness tends to form carbon deposits. Unfortunately, the quality of gasoline in our country is still relatively low compared with developed countries. Some car owners use gasoline cleaners in gasoline to ensure the cleanliness of gasoline. This can effectively prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon particles to slowly remove, thereby protecting the engine from harm. However, the addition of gasoline cleaner must be careful, if you add a counterfeit product will have the opposite effect.
Second: Do not drive for a long time
The idle time is long, and the time for the engine to reach normal temperature also becomes longer. After the gasoline is sprayed on the back of the valve, the evaporation speed is slow, and carbon deposition occurs. At the same time, often idling, the air flow into the engine is also small, so that the erosion of carbon deposition is also very weak, it will promote the deposition of carbon deposits.
Third: Run more speeds, try to increase the shift speed
The purpose of multi-run high speed is to use the effect of airflow on the scouring of the intake port to prevent carbon deposition. In addition, increasing the speed of shifting is similar to that of multi-speed high speeds, converting the original shift to a 2500 shift at a speed of 2,000, which can not only effectively prevent the generation of carbon, but also improve the dynamic performance of the car, and also avoids the need to change. Blocking vibration caused by too low speed protects the engine.
Fourth: Attention to the timing of car kill
For cars equipped with turbochargers, do not stop the car immediately after driving at a high speed or climbing a hill. After 10 minutes of idling, stop the car. Because the car equipped with a turbocharger has a lower rate of carbon deposition. Naturally aspirated cars are several times faster.
Due to the influence of urban road conditions, people’s living rhythm, and China’s fuel market conditions, the above methods of avoiding carbon deposition may not be easy to achieve. Therefore, it is recommended that the vehicle owners do the disassembly-free cleaning of the air intake system every 20,000 to 40,000 kilometers under the conditions of conventional maintenance, that is, the special-purpose equipment-specific method for the intake of the vehicle should the engine not disintegrate. Roads, valves, oil passages, etc., where carbon deposition is likely to occur, perform carbon deposition. This can effectively reduce the impact of carbon deposition on engine performance and keep the car's "heart" in its best condition.
Tungsten carbide pellets are small, cylindrical or spherical shapes made from tungsten carbide, a hard and dense material. These pellets are typically used in various industrial applications, such as drilling, grinding, cutting, and wear-resistant components.
Tungsten carbide is a compound of tungsten and carbon, known for its high hardness, strength, and resistance to wear and corrosion. It is often used as a cutting tool material, as well as in the production of mining and drilling equipment.
The pellets are usually produced through a process called powder metallurgy, where Tungsten Carbide Powder is mixed with a binder material and then compacted under high pressure. The compacted pellets are then sintered at high temperatures to form a solid and durable product.
Tungsten carbide pellets are used in various industries, including mining, construction, oil and gas, and manufacturing. They are commonly used as inserts in drilling bits, cutting tools, and wear-resistant parts, providing high performance and extended tool life.
Overall, tungsten carbide pellets are essential components in many industrial applications, offering superior hardness, strength, and wear resistance.
