What Does Fuel System Cleaning Include?

Automotive fuel system cleaning includes: water spraying, cleaning agent application, car body washing, rinsing, drying, and tire cleaning and waxing. Considering the quality of domestic fuel, it is recommended to clean the throttle body, fuel injectors, and fuel system every 20,000 kilometers. Fuel system cleaning already includes fuel injector cleaning, so it is also necessary to clean the intake tract, which is the section from the throttle body to the engine intake valve. This can be done using a no-disassembly cleaning method. Precautions for automotive fuel system cleaning: 1. Note one: The fuel pump draws fuel from the tank into the lines and maintains a pressure of about 2.5 kilograms. 2. Note two: The fuel filter is located between the fuel pump and the fuel pressure regulator, serving a filtering function to remove harmful particles and moisture from the fuel. 3. Note three: The fuel pressure regulator controls the pressure in the fuel lines, and the fuel is then sprayed as a mist through the fuel injectors, mixing with air before entering the cylinders (some engines use direct injection into the cylinders).

Is there only one side mirror that tilts down when reversing?

Only one side mirror tilts down when reversing. The reasons and functions for having only one mirror tilt down are as follows: Reasons for having only one mirror tilt down: Generally, it is the passenger-side mirror that tilts down, while the driver-side mirror usually does not. This is because the passenger side has a larger blind spot when reversing, and the driver cannot see the area closest to the passenger door. This helps prevent collisions with low obstacles like poles or curbs. Function of the tilting side mirror: It provides the driver with a view of the ground while reversing, ensuring driving safety. There are two methods to enable this feature: one is by adjusting the mirror control knob, and the other is through the central control system settings. The automatic mirror tilt function can be activated when reversing. Additionally, it can be set by adjusting the memory seats.

What are the reasons for a car having power but not starting?

Possible reasons for a car having power but not starting include untimely lubrication of friction surfaces, damage to the lubrication film on the cylinder walls, and excessively low vehicle coolant temperature. Insufficient fuel: When the car lacks a power source, it naturally won't start. If the failure to start is due to lack of fuel, this situation is relatively easy to resolve. Generally, the P or N gear is the correct gear position for starting an automatic transmission vehicle. Incorrect gear selection: Some drivers may not shift to the P gear when parking and turning off the engine, instead leaving it in the D gear. Alternatively, the car may be out of fuel. Apart from a dead battery causing failure to start, a car without fuel also cannot start.

Why Does It Still Show Low Tire Pressure After Inflating?

After inflating, the reason it still indicates insufficient tire pressure is because the tire pressure has not been recalibrated. Simply recalibrate the tire pressure on the central control panel. Tire Pressure Maintenance: Before traveling, observe the condition of the tires. While driving, pay attention to the sound of friction between the tires and the ground, feel the cushioning effect when driving over uneven roads, and notice if there are any changes in acceleration when pressing the gas compared to usual. Normally, check and replenish the tire pressure at a professional tire repair shop every week. The Relationship Between Tire Pressure and Performance: The relationship between tire pressure and load capacity: tire pressure is an indicator of a vehicle's load capacity. The size of the vehicle's load depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity.

Do I need to replace my C1 driver's license after one year of the probationary period?

C1 driver's license does not need to be replaced after one year of the probationary period. Reasons for not needing replacement: According to Article 47 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses", if the motor vehicle driver has not accumulated 12 penalty points in each scoring cycle during the six-year validity period of the motor vehicle driver's license, a motor vehicle driver's license with a ten-year validity period shall be issued; if the motor vehicle driver has not accumulated 12 penalty points in each scoring cycle during the ten-year validity period of the motor vehicle driver's license, a long-term valid motor vehicle driver's license shall be issued. Requirements for license replacement: The motor vehicle driver shall apply for license replacement at the vehicle management office of the issuing place of the motor vehicle driver's license within 90 days before the expiration of the validity period of the motor vehicle driver's license. When applying, the applicant shall fill out the application form and submit the required certificates and documents.

How Long Can a Car Be Parked on a Slope?

It is best not to leave a vehicle parked for more than two months, otherwise it may cause damage to the car's shock absorbers. Precautions for vehicle parking: Inflate the tires to standard pressure before parking, store a small amount of gasoline in the fuel tank, disconnect the battery's negative terminal, release the handbrake, use triangular blocks to secure the tires, and change the engine oil promptly. Hazards of long-term parking: When a vehicle is parked for an extended period, the air inside becomes stale and bacteria increase. Long-term parking may lead to leaks, and any issues should be repaired promptly. When tires remain in the same position on the ground, tire pressure drops more quickly. For vehicles with older batteries, prolonged parking may result in failure to start.

What Causes the Steering Wheel to Wobble When Released at Low Speed?

Steering wheel wobbling may occur after a certain mileage due to the loss of the original wheel balancing weights, wheel hub deformation, or front-end sway and steering wheel vibration at high speeds. Driving Posture: A correct driving posture is crucial for safe driving. It not only helps eliminate fatigue from prolonged driving and ensures good visibility but also makes driving actions more accurate and swift. After adjusting your driving position, always remember to fasten your seatbelt to avoid sudden panic and unsafe conditions caused by realizing it's unfastened while driving. Driving Precautions: Do not park in the emergency stopping lane, as it often contains discarded screws that can lead to traffic accidents. When preparing to overtake trucks or large vehicles, always be extra observant. Try to drive in the middle lane so that in case of any danger, you can switch to either the left or right lane.
