The following are the functions of cleaning fuel injectors: 1. Improve engine power and restore it to an optimal state; 2. Maintain smooth engine operation; 3. Reduce exhaust pollution emissions; 4. The fuel injector is a simple solenoid valve. When the electromagnetic coil is energized, it generates suction force, lifting the needle valve and opening the injection hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist that facilitates complete combustion. The recommended cleaning interval for fuel injectors is every 2 years or approximately 50,000 to 80,000 kilometers. Failure to clean them in time can result in insufficient engine power, idle shaking, and difficulty starting. Based on the cleaning procedure, it can be divided into non-disassembly cleaning and disassembly cleaning of fuel injectors. Note: The recommended cleaning interval for fuel injectors is every 2 years or approximately 50,000 to 80,000 kilometers.

The role of cleaning fuel injectors is absolutely crucial. After decades of driving, I've found that when injectors accumulate excessive carbon deposits, the fuel spray becomes uneven - causing severe engine vibration at idle, sluggish acceleration like dragging a rope uphill, and inexplicably increased fuel consumption. After cleaning, the engine runs much smoother with responsive throttle input, quicker start-up reaction, and more efficient fuel combustion. Regular cleaning prevents major issues like clogging or component damage, saving costly repairs later. This maintenance is especially vital for older vehicles.

Is Minor Transmission Oil Leak Serious?

Transmission minor oil leak is not serious. Here are the specific details about transmission oil leaks: 1. Causes: The main reasons for transmission oil leaks are damaged seals or pipeline ruptures. Pipeline ruptures cause oil to leak from the damaged area during circulation; at the connection between the transmission and the engine, damaged seals or loose fastening bolts can lead to widened gaps, reducing sealing effectiveness and causing oil to seep through the gaps. If the root cause is not addressed promptly, the leakage issue will persist. 2. Effects: Transmission oil leakage can result in insufficient lubrication, accelerating friction between gears. Oil also serves to cool and remove impurities within the transmission. Prolonged lack of lubrication can cause the transmission to fail.

What's the difference between replacing and repairing a cracked bumper?

Here are the specific differences between replacing and repairing a cracked bumper: 1. Extent of damage: If the internal bracket of the bumper is severely damaged or cracked, replacement is generally required; if the bumper only has minor cracks, welding repair can be chosen. 2. Impact: When replacing the bumper, it's best to choose an original equipment manufacturer (OEM) part. OEM bumpers are of higher quality than the original ones on the vehicle, being less prone to deformation even under high pressure and having minimal color difference. Although repairing the bumper may not show significant differences in color or strength, there may still be certain safety hazards after welding.

What is the difference between National IV and National V vehicle emission standards?

Here are the specific differences between National IV and National V standards: 1. Sulfur content: The sulfur content limit for National IV standard gasoline is 10mg; while for National V standard gasoline it's 50mg. 2. Emission limits: National V has stricter control on nitrogen oxides compared to National IV, with National V setting the emission limit at 25%. The National IV emission standard is China's fourth-phase motor vehicle pollutant emission standard, with main vehicle pollutants being HC, NOx, CO, PM, etc. Compared to National IV, the National V standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles.

Why do car lights sometimes flicker?

Car lights sometimes flicker due to poor contact in the lights, wiring, or switches. You can directly visit a 4S shop for inspection and repair. If the entire vehicle is under warranty, the headlight assembly can be replaced for free, as the headlights share the same warranty as the whole vehicle. Car headlights, commonly known as "headlamps," are responsible for nighttime driving illumination and can be considered the eyes of the car. Precautions: 1. The "soul" of the headlight is the bulb. Its performance directly affects nighttime illumination and driving safety. Therefore, high-quality headlight bulbs should be used to ensure safety. 2. Low-quality headlights have the following hazards: (1) Low-quality bulbs have a short lifespan and cannot guarantee stable quality. (2) High-quality bulbs have good light distribution, high brightness, while low-quality bulbs lack sufficient brightness, poor focus, and short range. During overtaking, they can cause visual illusions for the driver, leading to accidents. (3) Low-quality headlights, due to poor sealing, are prone to water ingress during rain or car washing, causing fog inside the lamp. In severe cases, this can lead to short circuits and fires. Therefore, when modifying headlights or replacing them due to damage, never consider low-quality bulbs.
