Reasons for Severe Vibration When Braking in D Gear

The reasons for vibration when braking in D gear are as follows: 1. After severe clutch wear, 'sliding friction' may occur when stopping in D gear; because wear reduces the friction between the two, and sliding friction can cause abnormal vibrations, rapidly increasing the clutch temperature. Therefore, stopping in D gear at relatively low temperatures may result in regular resonance or abnormal noises. 2. All torque converters can also wear out, and severe wear cannot rule out the possibility of abnormal slipping; coupled with wear or looseness of the power output shaft, or issues with the transmission gear bearings, irregular resonance when stopping in D gear is highly likely. 3. Carbon deposits can cause engine idle vibration. When in D gear, the engine needs to output power, and the RPM will be slightly higher than idle speed; however, if the throttle, intake and exhaust valves, spark plugs, or fuel injectors have severe carbon buildup, the air-fuel mixture and combustion efficiency at low RPMs will deteriorate.

What does 'several liters of fuel consumption' mean?

It refers to the average fuel consumption of a vehicle per 100 kilometers traveled, measured in liters per 100 kilometers (L/100km). Below is an introduction to two fuel consumption evaluation metrics: 1. Constant-speed fuel consumption: This is a fuel economy indicator when a vehicle travels at a constant speed on a good road surface. Since constant-speed driving is a fundamental operating condition for vehicles on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Road cycle fuel consumption: This is a fuel economy indicator measured when a vehicle follows specified speed and time protocols for repeated cyclic driving on roads, also known as multi-condition road cycle fuel consumption. The speed and time protocols specify various driving conditions for each cycle, including gear shift timings, braking and stopping times, as well as driving speeds, acceleration, and braking deceleration values. Therefore, the fuel economy measured this way is closer to the actual driving conditions of the vehicle.

How to Pass the Exhaust Emission Test During Annual Inspection?

Exhaust emission testing is a mandatory item during the annual inspection of vehicles. To pass the exhaust emission test during the annual inspection, regular maintenance of the three-way catalytic converter is essential. Use cleaning solvents, drip cleaning, or non-disassembly cleaning methods for the three-way catalytic converter. Some 4S shops offer this service. Before the test, try to use up the fuel in the tank and then refill with higher-grade fuel from a reputable gas station, as this can help with the emission test. If the vehicle has been used for a long time and shows signs of corrosion in the exhaust pipe, it is advisable to have it inspected and repaired promptly. If necessary, replace the exhaust pipe to improve the chances of passing the emission test. Severely corroded exhaust pipes usually make it difficult to pass the test. Nowadays, when purchasing vehicle insurance, insurance companies often provide inspection cards that assist with the annual inspection and exhaust emission testing, saving a lot of hassle. Dedicated channels can also help ensure a smooth emission test. Be sure to check with the insurance company if they assist with the emission test. Many vehicle owners lack confidence in their vehicle's condition and may attempt to pay someone to 'help' pass the emission test.

Why can't the rear seat buckle stay fastened?

Rear seat buckles may not stay fastened due to damage or misalignment. Below is a classification of car seats: 1. By shape: Split seats, bench seats. 2. By function: Fixed, removable, adjustable. 3. By passenger capacity: Single, double, multi-seat. 4. By performance features: Air-cushion seats, power seats, stereo seats, fatigue-recovery seats, electronically adjustable seats. Here is extended information about the function of child safety seats: 1. Seatbelt: Child safety seats function similarly to seatbelts. 2. Protection: The raised sides of child safety seats provide better wrapping and improved protection for a child's head and sides. 3. Injury reduction: During collisions or sudden deceleration, they reduce impact forces and limit body movement, thereby minimizing injuries.

Why is the car's airbag light constantly on?

The following are situations where the airbag light may illuminate: 1. Instrument self-test When entering the car and starting the ignition, the instrument panel will perform an automatic self-check. After the self-check is completed, the airbag light will automatically turn off. This process usually takes about 5 seconds and is a normal phenomenon. If the airbag light remains on for a long time after the self-check, it can be determined that there is a genuine fault. 2. False fault If the car battery is low on power, it may also cause the airbag light to illuminate. Additionally, the airbag system may feedback a signal indicating low pressure in a certain airbag, generating a fault code. In this case, simply clearing the fault code will resolve the issue. 3. Genuine fault If the above two reasons are excluded, then it may be a wiring fault that requires timely repair. The cause of this fault could be related to the airbag itself, collision sensors, airbag clock spring, or other wiring-related issues.

What to Use to Wash a Car for a Thorough Clean

Using car wash wax provides a thorough clean and enhances the paint's shine. The functions and usage methods of car wash wax are as follows: Functions of car wash wax: After washing, it reduces friction caused by high-speed driving and tiny airborne particles, minimizing paint wear and slowing oxidation. It also offers excellent anti-oxidation effects, as the wax contains a unique invisible film that effectively absorbs UV rays from sunlight. Usage method of car wash wax: First, rinse the car with high-pressure water, then spray the car wash wax solution (mixed at a ratio of 1:150) onto the paint surface using a spray bottle. Finally, rinse and wash the car with tap water simultaneously. Compared to regular car wash solutions, car wash wax places more emphasis on paint care. By increasing the quantity and variety of wax during the washing process, the car's body appears brighter and more lustrous.
