The internal structure of the muffler is damaged, or the exhaust pipe is blocked, causing a change in the flow cross-sectional area and resulting in a popping noise. There may also be air leakage at the connection between the exhaust pipe and the muffler. Below is an introduction to the exhaust pipe: 1. Introduction: The exhaust pipe is part of the engine's exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe generally consists of a front exhaust pipe and a rear exhaust pipe. 2. Angle Design: The exhaust angle of vehicle exhaust pipes has always been a challenging issue for professional manufacturers. Based on surveys, the exhaust pipe angle for cars and light household vehicles is usually parallel to the ground and directed backward, while the exhaust pipe angle for high-power transport vehicles and agricultural vehicles is bent toward the ground. 3. Water Drainage: It is actually a good sign if water drips from the car's exhaust pipe. This indicates that your car's engine is burning fuel efficiently, and as a result, the exhaust pipe may discharge water. This is a normal phenomenon and is not related to any issues with the exhaust pipe itself.

How to Adjust the Rearview Camera?

We only need to turn on the vehicle's ignition switch, shift into reverse gear, and then go to the location where the rearview camera is installed at the rear of the vehicle. Generally, it is installed at the position of the license plate light on the trunk lid, or sometimes under the rear bumper. You can see that the rearview camera is lit, indicating it is working properly. The rearview camera should be installed with the center of the vehicle's width as the reference point to ensure a more comprehensive rear view.

How to Deal with Scratches from Tree Branches on a Car

First, clean the scratched area of the car body with dish soap. It's fine to use dish soap for car washing—don't listen to claims that it damages the paint, as this is simply not true. Apply Turtle Wax Scratch & Swirl Remover lightly over the scratched area, covering it in a straight line. Use the included polishing sponge to apply the scratch wax to the scratched area in a 360-degree circular motion, ensuring even coverage. It's best to follow up with polishing wax, using a method similar to the third step of applying scratch wax. Find a soft, dry towel and polish the waxed area once more with the towel.

How to judge the distance behind when reversing?

When the vehicle enters the parking space and the body position is adjusted, we can find the most accurate point to stop after entering the parking space by observing the position of the lower edge of the left rearview mirror and the boundary line. When reversing with the steering wheel straightened, sitting in the driver's seat and observing the left rearview mirror and the boundary line, you can see the distance between them continuously decreasing. When the rearview mirror just blocks the boundary line, immediately press the clutch and brake to stop. That is to say, the most accurate point to stop after entering the parking space is the moment when the left rearview mirror just covers the boundary line. When the edge of the front of the car coincides with the lower edge of the tire of the car in front, the distance from the car in front is approximately 5 meters.

How to Inspect Overweight Vehicles?

Truck annual inspection overweight, the reason may be due to self-installed guardrails, excessive heavy cargo inside the vehicle, etc. All items inside the truck must be emptied, such as toolboxes, tires, etc. These items can reduce weight, and other heavy cargo inside the vehicle should be carefully checked. During the inspection, these self-installed facilities must be removed. If there are reinforcement facilities like keels or wooden boards in the cargo box, they should also be taken off. If necessary, spare tires, spare tire mounting brackets, and toolboxes, along with other accessories that affect the vehicle's total weight, should also be removed.

Novice driver doesn't know how to steer when reversing?

Drive the car forward until it is roughly aligned with the front car in the parking space, with a horizontal distance of about one meter between the two cars. Adjust the angle of the right rearview mirror downward until you can see the right wheel. After the vehicle starts moving, immediately shift your gaze from the right rearview mirror to the left rearview mirror, paying attention to oncoming traffic and obstacles on the left side. Slowly reverse while turning the steering wheel to the maximum. Observe the distance between the right rear wheel and the curb. When you feel it's appropriate, turn the steering wheel fully to the left and try to get the car as close to the curb as possible, while maintaining enough distance to straighten the car body.

How to Deal with Water in the Exhaust Pipe?

If you encounter water in the exhaust pipe and the engine stalls, do not attempt to force a restart. Instead, call for roadside assistance immediately. After a simple cleaning and drying process, the engine will resume normal operation. Insurance claims are usually straightforward in such cases. Drive fast on sand, but slow through water. When driving at high speed, the waves created by the tires can easily enter the exhaust pipe, causing the vehicle to stall. If water enters the exhaust pipe, remove the accumulated water as soon as possible to prevent impurities in the water from clogging the catalytic converter or damaging the oxygen sensor.
