Fuel system cleaning is necessary for the following reasons: 1. Fuel inherently contains colloids, impurities, dust, and moisture, which can form sludge deposits in areas like the fuel tank and fuel lines over time; 2. Carbon deposits and sediments can clog fuel injector needle valves and valve orifices, impairing the performance of precision components in the fuel system, leading to poor fuel injection, inadequate atomization, and reduced power performance; 3. Carbon deposits and sediments may cause intake valves to close improperly, resulting in decreased cylinder pressure or even backfiring, leading to unstable engine idling, increased fuel consumption, and worsened exhaust emissions. It is recommended to periodically use high-quality throttle or intake system cleaners to remove colloids and deposits from the throttle body and intake pipes, as well as carbon buildup from intake valves, combustion chambers, and the three-way catalytic converter, restoring normal compression ratio.

Can I Drive Without Carrying My Physical Driver's License If I Have an Electronic Version?

Having an electronic version of the driver's license allows you to drive without carrying the physical one, but since electronic driver's licenses have not been fully implemented in some regions, it is still advisable to carry your physical driver's license with you. Below is relevant information about driver's licenses: Driver's License: The People's Republic of China Motor Vehicle Driver's License, commonly referred to as a driver's license or 'driver's permit,' is a mandatory document issued in accordance with the laws of the People's Republic of China for individuals who operate motor vehicles. The driver's license records the holder's ID number, name, gender, date of birth, permanent address, nationality, permitted vehicle type code, initial issuance date, validity period, and management records. It also includes the issuing authority's seal, file number, and the holder's photo. Application Location: Applicants residing in their household registration area should apply there; those residing temporarily should apply at their temporary residence location. Active-duty military personnel (including armed police) should apply at their place of residence. Foreign nationals should apply at their place of residence. Those applying to add permitted vehicle types should apply at the location where their current driver's license was issued. Driver's License Process: Medical Examination: A pre-enrollment physical examination is required before registering at a driving school. Registration: Applicants can register at the local vehicle management office or a driving school. Examination: Applicants must pass all four subjects of the driver's license examination to obtain their license.

How Long Can a License Plate Be Retained?

If the original license plate has been used for more than one year and the vehicle owner has owned the original vehicle for more than three years, they can apply to retain the original license plate within six months after completing the transfer or deregistration process (these six months include weekends). The original license plate can be retained when the vehicle is transferred, deregistered, or relocated, or when purchasing a new or used vehicle. Before retaining the license plate, ensure all traffic violations and accident-related matters have been resolved. Important Notes Regarding License Plates: If a vehicle owner plans to sell their vehicle, the license plate can be retained for up to one year. However, the buyer of the vehicle cannot continue using the previous owner's old license plate. If the old license plate is no longer needed, it must be surrendered. If unused for one year, it will be recycled into the number resource pool. The vehicle management office may periodically release these numbers when the available pool is insufficient. An online selection system "20-50 Choose 1" has been introduced, fully implementing internet-based pre-selection of license plate numbers. Vehicle owners can select their preferred license plate numbers via the Traffic Safety Comprehensive Service Management Platform website or the mobile app "Traffic Management 12123." Owners can choose between random selection or self-composed selection based on their preferences. The random selection option has been expanded from 10 to 20 choices. In areas with abundant license plate number resources, the selection range may be increased to 30-50 options.

Can You Continue Driving When the DEF Light Comes On in a Diesel Vehicle?

When the DEF light in a vehicle is illuminated, you can drive for a short distance, but prolonged driving is not recommended. This indicates that the vehicle's auxiliary water tank is low on water and needs to be refilled promptly. The illumination of the DEF light in a vehicle signifies that the auxiliary water tank is low on water. If the small mileage display on the dashboard shows "DEF," it indicates an internal processor fault in the dashboard. If the auxiliary water tank is low on water, it must be refilled immediately. If the issue is with the internal dashboard processor, you should promptly visit a local 4S shop for repairs. The vehicle dashboard is a device that reflects the working conditions of various systems in the car. The reasons for low water in the auxiliary water tank include: leaks in the cooling system or minor issues with the cylinder head gasket; high coolant temperature causing system water shortage; a seized water pump leading to timing belt damage and piston valve contact; or a blown cylinder gasket mixing with engine oil or being expelled through the exhaust pipe. The auxiliary water tank is a component of the engine cooling system and helps balance the pressure in the radiator. Maintenance methods include: stopping to check if the temperature is too high while driving; promptly stopping to check if the radiator emits smoke; and regularly replacing the coolant.

Is the same instructor used for Subject 2 and Subject 3?

Generally, there are no special circumstances, and the same instructor teaches both Subject 2 and Subject 3. This is because when students enroll in a driving school, the instructor usually continues to guide them until they obtain their driver's license. Subject 2 test items: The first item is reversing into a parking space, the second is parallel parking, the third is stopping and starting on a slope, the fourth is making a 90-degree turn, and the fifth is driving on a curved path. Subject 3 test items: The Subject 3 test items include: pre-test preparation, vehicle starting, driving straight, straight-line gear shifting, left turns, right turns, passing through traffic light intersections, crossing pedestrian crossings, overtaking, using lights during night driving, and pulling over to park.

What Causes Exhaust Gas in the Crankcase?

The reasons for exhaust gas generation in the engine crankcase include: 1. Piston ring wear: Severe wear of piston rings or cylinder liners, or issues with the breather; 2. Overfilling of oil: Excessive oil filling during refueling can also lead to increased exhaust gas emission from the crankcase; 3. Gas from the air pump: If the air pump is used for engine oil cooling, gas from the air pump might also be a cause. Functions of the engine crankcase ventilation system: 1. Preventing oil deterioration; 2. Preventing leakage from crankshaft oil seals and crankcase gaskets; 3. Preventing atmospheric pollution by various oil vapors.
