What Does Original Paint Mean for a Whole Car?

What is the fault when the EPC light is on and the car shakes?

EPC light on and car shaking indicate that the throttle is dirty, the engine has severe carbon buildup, or there is a problem with the fuel quality. The following are the specific reasons for the EPC light being on: 1. A dirty car throttle will affect the air intake and exhaust volume. At this time, the throttle should be cleaned. 2. The brake light is not working, which is an EPC triggered by an electronic system problem. The brake switch and wiring need to be checked. 3. Fuel quality issues. Poor product quality will affect the electronic system during combustion, so the EPC light will come on. Solutions for the car EPC light being on: 1. Troubleshoot the intake system, use fuel that meets standards, clean the throttle body, etc. 2. Remove carbon buildup from related parts and clean them. 3. Rewrite the ECU-related data. 4. The possibility of other faults cannot be ruled out. Specific repairs should be based on the actual vehicle inspection results.

Is Gasoline + 48V Mild Hybrid System Considered a Hybrid?

Gasoline + 48V mild hybrid system is actually a more efficient hybrid power system, which has begun to be successively installed in high-end sedans such as the Audi A8L and will become the main trend of mild hybrid systems in the future. Compared with the ordinary 12V hybrid system, the 48V mild hybrid system has many advantages, mainly reflected in the electrical support and optimization for braking, starting, and start-stop systems. More information about the gasoline + 48V mild hybrid system is as follows: 1. When the engine is at low speed, the 48V mild hybrid system can maintain the operation of the air conditioning. Additionally, the 48V mild hybrid system with a power system can assist the vehicle in starting, using electricity during the most fuel-consuming starting process to effectively save fuel. 2. The battery life of the 48V mild hybrid system generally exceeds 5 years. The 48V mild hybrid system uses a 48V battery, so both the cost and technology are significantly higher than those of the 12V system. The 48V mild hybrid system mainly consists of a motor, battery, and voltage converter.

What Are the Causes of Windshield Wiper Squeaking?

The causes of windshield wiper squeaking can be summarized into the following 5 points: 1. If the wiper squeaks when moving upward, it indicates the wiper frame is twisted upward. If the squeaking occurs when moving downward, the frame should be twisted in the opposite direction until the noise disappears; 2. Issues with the wiper blade itself: Over time, the blade may age and harden. The simplest solution is to replace it with a new one; 3. Foreign objects between the wiper blade and the windshield: Friction between the blade and the windshield can produce a sharp sound. Check and clean any debris under the wiper or the blade to ensure cleanliness; 4. Deformation of the linkage mechanism: Abnormal noises may also be caused by the motor, interval relay, or prolonged use leading to deformation, jamming, or rusting of the mechanism itself; 5. Incorrect angle between the wiper and the wiper arm: This can cause the wiper blade to jump on the windshield, resulting in squeaking.

Is a Car with Cylinder Scoring Still Worth Keeping After Repair?

Engine cylinder scoring can be repaired. The causes of cylinder scoring include the following: 1. Insufficient clearance between the piston and cylinder, poor lubrication between the piston and cylinder, or improper engine oil selection; 2. Piston ring breakage, seizure on the piston, or piston circlip breakage or detachment. The piston and piston ring tilt to one side, pressing tightly against the cylinder wall; 3. Prolonged high-speed or heavy-load operation without proper running-in after an engine overhaul. Poor engine cooling or faults in the engine cooling system; 4. Contaminated engine oil containing a large amount of impurities. Long-term overloading and low-speed driving. Cylinders produced by non-standard manufacturers with low hardness and poor quality. Air filter failure, allowing air impurities to enter the combustion chamber and deposit on the cylinder wall.
