The fuel supply system consists of the gasoline supply device, air supply device, combustible gas mixture formation device, and exhaust emission device. Below is additional information about fuel additives: 1. Effectiveness of fuel additives: Fuel additives, commonly known as "fuel treasure," can to some extent clean the fuel injectors and fuel system, improve the atomization effect of the injectors, enhance the thorough mixing and combustion of air and gasoline, and use antioxidant detergents to remove gum and moisture from the fuel system, thereby achieving the effect of cleaning carbon deposits. 2. Testing of fuel additives: After adding fuel additives to vehicles, the tested vehicles showed no significant changes in power, and the same was true for instantaneous fuel consumption. The cleaning effect was also minimal. If one hopes to improve engine power or directly reduce fuel consumption by adding fuel additives, the results are likely to be disappointing.

As someone who often drives older cars on long trips, I believe the fuel delivery system is the key to a car's breathing, and there are quite a few core components. The fuel tank holds gasoline and is located underneath the rear of the car—its capacity affects the driving range. Next is the fuel pump; my first car had a mechanical pump, but now electronic pumps are hidden inside the tank to draw fuel—pressure instability can cause the car to sputter. The fuel filter acts like a kidney, filtering out impurities—if it's clogged, the power becomes sluggish, so I replace it every two years. The fuel lines transport fuel, like blood vessels connecting the pump to the engine—leaks can lead to high fuel consumption or even hazards. Finally, there's the fuel injector, which is computer-controlled to regulate fuel injection—if it gets dirty, combustion efficiency suffers. When these parts work together, a failed pump makes the car hard to start, a clogged filter slows acceleration, and aging lines pose risks. Regularly inspecting the fuel system can save a lot of trouble. My experience tells me: don’t overlook small components—they’re crucial to driving safety.

Having driven for over a decade, I've gained a thorough understanding of the fuel system. It primarily consists of the fuel tank, fuel pump, filter, fuel lines, and fuel injectors. The fuel tank is the source—larger capacity means fewer refueling stops. The fuel pump draws fuel; electric pumps are quieter but more prone to failure. The filter cleans out impurities—if clogged, acceleration becomes sluggish. Fuel lines connect all components—cracks require immediate repair. Fuel injectors deliver precise fuel sprays—malfunctions cause engine sputtering. I recommend owners pay attention to the filter replacement cycle, typically every 10,000–20,000 km, to prevent fuel pump damage—repairs are costly. Safety-wise, leaking fuel lines pose fire hazards—check the lines if you smell gasoline when parked. Simple maintenance extends lifespan—don’t wait until a roadside breakdown.

What should be noted when passing through a T-junction?

First, vehicles should slow down when passing through a T-junction. After confirming the safety on the left front, observe the incoming traffic from the right front, and only proceed through the T-junction when no potential hazards are identified. When navigating a T-junction, left-turning vehicles should prioritize observing the traffic on the left front, as the straight lane on the left is closest to their own lane and poses the greatest potential hazard from oncoming straight traffic. For vehicles going straight, since the direction from the left front is the most direct, it's essential to observe the traffic coming from the left front before entering the T-junction. Then, check the right front for incoming traffic, and before making a left turn, glance at the rearview mirror to ensure safety.

Can I Apply for Extended Warranty If My New Car Breaks Down Within a Week?

Can I Apply for Extended Warranty If My New Car Breaks Down Within a Week? You can apply for an extended warranty if your new car breaks down within a week, but you need to negotiate with the 4S dealership. Vehicle Insurance: Vehicle insurance, also known as motor vehicle insurance, abbreviated as auto insurance or car insurance, refers to a type of commercial insurance that covers liability for personal injury or property damage caused by natural disasters or accidents involving motor vehicles. Auto Insurance Considerations: If the insurance is purchased for a new car, the insured amount will be based on the actual purchase price of the vehicle. For renewal insurance, the insured amount will be determined based on the current price of a new car or the price of a used car. Therefore, during the insurance process, the actual value of the insured vehicle will be assessed to ensure full coverage, which guarantees reasonable compensation in case of an accident.

Why is the right side always wider when reversing into the garage on the right?

The reason why the right side is always wider when reversing into the garage on the right is that the steering wheel is turned fully to the left too late. Tips for reversing into the garage: Engage reverse gear, slowly release the clutch pedal, and start reversing the vehicle in a semi-engaged clutch state. After turning the steering wheel fully to the left, observe both side mirrors to adjust the vehicle's position while keeping the clutch semi-engaged, and reverse into the garage. After entering the garage, look at the left rearview mirror and stop when the lower edge of the mirror aligns with the front line of the garage. The reversing process is then completed. Precautions for reversing into the garage: When reversing into the garage, pay attention to the situation behind the car. You can use the assistance of the reversing camera to observe the rear state of the vehicle to avoid scratches during reversing. Additionally, it is important to reduce the speed while reversing.

How many points are deducted for driving a car without annual inspection?

Driving a motor vehicle without annual inspection will result in a deduction of 3 points per violation. Vehicle Annual Inspection: Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. The annual inspection helps promptly eliminate potential safety hazards, encourages enhanced vehicle maintenance, and reduces the occurrence of traffic accidents. Vehicle Annual Inspection Process: Before the inspection, staff will conduct a preliminary check, briefly examining the appearance and condition of the vehicle, followed by filling out an exhaust emission test form. At the inquiry window, collect and fill out the "Motor Vehicle Periodic Inspection Registration Form," which can be obtained using the vehicle registration certificate. Pay the deposit at the deposit window, keep the deposit receipt, and collect and fill out the appearance inspection form. Bring the appearance inspection form to the appearance inspection station, where relevant procedures will be verified, including checking whether the third-party liability insurance (compulsory insurance) is still valid.
