The car has been rear-ended. What should I do?
Answer: Make big issues small, and small issues disappear. The other party didn't do it on purpose either. Letting them off might be better. As the mileage of your beloved car increases, various faults will also appear. Some faults can be avoided, but some obstacles cannot be avoided and can only be dealt with effectively to reduce the harm caused by such faults.

Hazards of Carbon Buildup
Common problems during vehicle use include cold engine shaking, idling engine shaking, reduced power, increased fuel consumption, all of which are related to carbon buildup inside the engine. After carbon buildup occurs, it can cause poor engine performance, making starting difficult, unstable idling, poor acceleration, excessive emissions, and increased fuel consumption. Carbon buildup can affect the car as follows: 1) reducing engine power, 2) increasing fuel consumption, 3) making cold starts difficult, 4) severe carbon buildup in the combustion chamber can lead to engine knocking! Low-speed acceleration produces noise, damaging the piston and crankshaft. 5) Emissions exceed standards, Dongfeng sprinkler truck price.
Carbon buildup can be divided into valve, combustion chamber carbon buildup and intake manifold carbon buildup.
1. Valve, Combustion Chamber Carbon Buildup
Due to the characteristics of electronic fuel injection engines, each time the cylinder works, it sprays fuel first and then ignites. When we ignite the engine, the ignition is immediately cut off, but the fuel sprayed during this work cycle cannot be recovered and can only adhere to the intake valve and combustion chamber walls. Gasoline evaporates easily, but the wax and resin in gasoline remain, accumulating over time and hardening after repeated heating to form carbon deposits. If the engine burns oil or the quality of the gasoline added is poor with many impurities, then the carbon buildup on the valve will be more serious and form faster. Since the structure of carbon buildup is similar to a sponge, when carbon buildup forms on the valve, part of the fuel sprayed into the cylinder will be adsorbed, making the actual concentration of the mixed gas entering the cylinder thinner, causing poor engine performance, difficulty starting, unstable idling, poor acceleration, backfire when accelerating suddenly, excessive emissions, and increased fuel consumption. If it gets worse, it may cause the valve to close improperly, making a certain cylinder completely non-functional due to lack of pressure, or even sticking the valve so that it does not return to position. At this point, there will be mechanical interference between the valve and the piston, ultimately destroying the engine.
2. Intake Manifold Carbon Buildup
Since the pistons of the entire engine do not work synchronously, when the engine is ignited, some cylinders' intake valves cannot fully close, allowing unburned fuel to continuously evaporate and oxidize, producing some soft black carbon deposits in the intake manifold, especially behind the intake valve. On one hand, these carbon deposits make the walls of the intake manifold rougher, creating turbulence in the intake air at these rough spots, affecting the intake effect and the quality of the mixed gas. On the other hand, these carbon deposits block the idle channel, causing the idle control device to jam or exceed its adjustment range. This results in low idle speed, idle shaking, malfunctioning of various auxiliary devices, stalling when releasing the throttle, excessive emissions, and high fuel consumption.
For the issue of carbon buildup, we should try to prevent or reduce the formation of carbon deposits during daily car use to extend the life of the engine.
1. Regular maintenance and cleaning
If possible, during routine car maintenance, specialized cleaning equipment can be used to clean areas prone to carbon buildup, such as the intake manifold and oil passages, without disassembly.
2. Use higher-grade gasoline whenever possible
Wax and resin impurities in gasoline are major components causing engine carbon buildup. In other words, cleaner gasoline has a relatively lower tendency to form carbon deposits. Adding higher-grade gasoline has a higher octane value compared to lower-grade gasoline, burning more completely and cleanly, thus significantly reducing the possibility of carbon buildup.
3. Use suitable gasoline additives
You can use some reputable brands with good after-sales service or gasoline additives recommended by car manufacturers.
Currently, the commonly used gasoline additives on the market are roughly divided into two types: one type focuses on enhancing combustion for maintenance purposes; the other is mainly for removing carbon deposits for cleaning purposes. You can classify and add according to different usage conditions and mileage of different cars. Note that you should not mix additives of different functions and brands, and pay attention to the addition method indicated in the product instructions.
4. For manual transmission vehicles, try to increase gear-shifting RPMs and occasionally drive at high speeds
Increasing RPMs when shifting gears and driving at high speeds actually utilize large amounts of incoming air to flush the intake manifold, preventing and reducing carbon deposit accumulation, thereby improving the car's power performance. It is generally recommended to shift gears between 2500 and 3000 RPM. Where can I buy a brand new 10 cubic meter water sprinkler?
5. Avoid long periods of idling
Frequent idling use easily causes carbon buildup, and insufficient air intake further promotes carbon deposit formation. For turbocharged engines, the likelihood of carbon buildup is higher than for normal naturally aspirated vehicles. Therefore, after high-speed driving or climbing hills, avoid immediately turning off the engine and parking. Instead, let the engine idle for about 10 minutes to prevent carbon buildup.
