What Causes the Abnormal Noise When Starting and Turning?

What to Do If the Exhaust Pipe Leaks?

If a car's exhaust pipe leaks, it is usually due to long-term water accumulation causing rust damage, which leads to muffler failure. Replacing the muffler will solve the issue. Additional Information: 1. Typically, a car's exhaust system consists of several components, arranged from the engine as follows: exhaust manifold, catalytic converter, flexible joint, main muffler, and auxiliary muffler. 2. If there is damage in the middle of the exhaust pipe, it will result in increased noise from the car. 3. The most common damage to a car's exhaust pipe is the muffler being corroded by the exhaust gases emitted by the engine. 4. If the catalytic converter is damaged, not only will the noise increase, but the exhaust emissions will also fail to meet standards. This can affect the car's power performance. However, it does not necessarily mean a loss of power; in some cases, it might even increase power.

What are the reasons for a China V diesel vehicle failing to start?

Here are the reasons why a China V diesel vehicle may fail to start: 1. Low ambient temperature: In cold weather, the diesel engine should be preheated properly, otherwise it may be difficult to start. 2. Air or excessive moisture in the fuel supply system: The symptom is that the starting speed is not low but the engine does not ignite, and white smoke comes out of the exhaust pipe. The inspection method is to loosen the vent screw on the diesel filter or the high-pressure fuel pipe on the high-pressure pump. If air comes out, it indicates the presence of air. The solution is to tighten all fuel line connections, then loosen the vent screw on the high-pressure pump and turn the crankshaft to remove the air. If water is found in the diesel, it can be removed in the same way. If there is too much water in the diesel, the diesel needs to be replaced. 3. Blockage in the pipeline or filter: The solution is to use an air pump to clear the pipeline, clean the filter, and check whether the fuel tank filler screen is intact.

At what point should spark plugs generally be replaced?

Severe erosion of spark plugs If the top of the spark plug is scarred, damaged, or the electrodes are melted or eroded, it indicates that the spark plug is damaged and should be replaced. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition based on the following color indicators. A normal spark plug will have a skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is contaminated with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs such as scarring, black streaks, cracking, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or the mixture is too rich, with oil seeping up.

What does National VI plus urea mean?

National VI plus urea is to reduce environmental pollution. The following is a related introduction to vehicle urea: 1. Measures to be taken when it is found that the truck does not consume vehicle urea: If it is found that the vehicle urea has not been consumed, or when the vehicle emission light is on, it may be that the vehicle's SCR system has stopped working (commonly known as not "burning" urea), and this problem cannot be solved by oneself. You should immediately go to a professional 4S shop for inspection and repair. Urea pump damage, urea pipeline blockage, nozzle blockage, etc. 2. Consequences of trucks not consuming vehicle urea: Environmental pollution: Diesel vehicles without urea will have an extremely bad impact on the ecological environment, and this is also not allowed by national laws and regulations. The power becomes weaker, which is not a direct impact caused by the lack of vehicle urea, but when the engine electronic control system does not detect urea injection and the exhaust pollution exceeds the standard, it will forcibly limit the torque output of the engine. If there is no urea for a long time, the nozzles, pipelines, and urea pump in the SCR system may crystallize and block, or be damaged by high temperature.

How to Turn the Steering Wheel When Reversing?

When reversing, the method to control the steering wheel is: 1. If you want the rear of the car to go left, turn the steering wheel to the left; if you want the rear to go right, turn the steering wheel to the right. 2. To straighten the car body when the rear is leaning left, turn the steering wheel to the right; if the rear is leaning right, turn the steering wheel to the left. 3. After correcting the car body, straighten the steering wheel and reverse slowly. The function of the steering wheel is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. The correct way to hold the steering wheel is: 1. Imagine the steering wheel as a round clock face. 2. Place your left hand at the 9 o'clock position and your right hand at the 3 o'clock position. 3. Hold the steering wheel lightly with both hands, with thumbs naturally extended and resting on the edge of the steering wheel. 4. The four fingers should lightly grip the steering wheel from the outside inward.

How to Identify the Model of a Car Battery?

Look at the numbers on the battery; these numbers indicate the battery's rated capacity. The rated capacity, also known as the design capacity, is one of the key indicators for evaluating battery performance. Below is relevant information about car batteries: 1. Cold Cranking Amps (CCA): The minimum current that can be obtained under specific conditions at -17.8°C and -28.9°C. This indicator links the battery's starting capability with important variables such as engine displacement, compression ratio, temperature, starting time, the technical state of the engine and electrical system, and the minimum operating voltage for starting and ignition. It refers to the minimum current that a fully charged 12V battery can supply within 30 seconds when its terminal voltage drops to 7.2V. The cold cranking rating provides the total current value. 2. Reserve Capacity: The approximate time a car can operate at night using the battery for ignition and providing minimal circuit load when the charging system is not working. Specifically, it refers to the discharge time of a fully charged 12V battery at 25°C, discharging at a constant current of 25A until the battery's terminal voltage drops to 10.5V.
