How Significant Is the Impact After an Accident Vehicle Is Repaired? How Many More Years Can It Be Driven?

Impact after an accident vehicle is repaired: 1. Impact one: After a traffic accident, the vehicle will suffer from strong impact forces, resulting in varying degrees of damage. In severe cases, the entire body of the vehicle may be completely disfigured. Although there are many auto repair shops currently, due to the low technical level of repair personnel and the use of outdated equipment during the repair process, the repair results are not optimistic, leading to a lack of safety and reliability in the repaired vehicle. 2. Impact two: Although an accident vehicle can be restored to its original appearance after repair, its fatigue life cannot be fully recovered. Moreover, general accident vehicle repairs often do not follow the manufacturer's specified repair methods, leading to further reductions in strength. Therefore, it is important to assess whether the accident vehicle can be fully restored; vehicles that cannot be fully restored are not recommended for purchase. 3. Impact three: The depreciation issue of accident vehicles. For vehicles with higher original value, details such as replacing a bumper have a greater impact on the overall resale value. Conversely, for vehicles with lower initial value, certain defects are not magnified. Compared to fatal damages like the anti-collision beam, chassis, or engine, replacing a bumper is almost negligible. How many years can an accident vehicle be driven after repair? Based on the designed service life of over 20 years for automobiles, if the accident vehicle can be restored to the factory's technical level, its service life can still be quite long. Even a new car can be used normally for ten or eight years after being repaired following an accident. Of course, for vehicles that cannot be restored to their original technical condition, it is difficult to determine how many years they can still be used, as safety hazards are unpredictable. If they can be used for another 4-5 years, it would already be quite good.

What are the effects of not having a three-way catalytic converter on a car

It has no effect on the car, but it has a very significant impact on the environment. If the three-way catalytic converter is damaged, the car will emit a large amount of harmful gases, and may even cause harmful gases to enter the car, affecting the health of the occupants. If the three-way catalytic converter is not repaired in time, it may cause the vehicle to fail the annual inspection, resulting in fines, vehicle impoundment, and other situations. The three-way catalytic converter is the most important external purification device installed in the vehicle's exhaust system. It can convert harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. The following are the effects of a damaged three-way catalytic converter on the car: 1. Symptoms of a damaged three-way catalytic converter: Shortly after the vehicle is started, the exhaust manifold emits a noticeable red burning phenomenon to the three-way catalytic converter, and a hissing sound of air leakage and gurgling can be heard when accelerating. 2. Consequences: If the three-way catalytic converter is damaged, the secondary oxygen sensor will not be able to accurately provide data to the driving computer. As a result, the concentration of the air-fuel mixture will become too lean or too rich. If it is too lean, it will cause difficulties in ignition, weak driving, and engine misfires. If it is too rich, it will increase fuel consumption, incomplete combustion, and severe carbon deposits in the cylinders and spark plugs. When this fault occurs, the engine fault light should illuminate.

What Happens When a Motorcycle Engine Overheats?

Here are the specific hazards: 1. Decrease in engine charging efficiency: The higher the temperature, the lower the air density, resulting in reduced actual air intake by the engine. Due to engine overheating, the temperature inside the engine compartment rises further, diminishing the engine's charging capacity. This decline in charging efficiency leads to a drop in engine power, causing the vehicle to lose driving force. Additionally, as the charging efficiency decreases, the air-fuel mixture becomes relatively richer, increasing the concentration of harmful substances (CO, HC, NOx, soot) in the vehicle's exhaust and exacerbating environmental pollution. 2. Abnormal engine combustion: High ambient temperatures raise the temperature of the air-fuel mixture entering the cylinders, elevating the overall operating cycle temperature of the engine. Coupled with the radiator's reduced cooling efficiency, the engine enters an overheated state. The end-gas mixture in the combustion chamber absorbs excessive heat, accelerating pre-flame reactions and increasing the likelihood of engine knocking. Furthermore, an overheated engine causes carbon deposits on the piston top, combustion chamber walls, valve tops, and spark plugs to form hot spots, potentially leading to premature ignition of the combustible mixture. This abnormal combustion further worsens the engine's overheating, creating a vicious cycle. The cylinder block and head are prone to thermal deformation or even cracking, with common issues including burning out the cylinder head gasket, valves, and valve seats. 3. Engine oil degradation: Under high temperature and pressure, the engine oil's oxidation stability deteriorates, hastening its thermal decomposition, oxidation, and polymerization. The oil mixes with incomplete combustion byproducts, condensed water vapor, and dust from the intake air, leading to oil degradation. Moreover, elevated oil temperatures reduce viscosity, thinning the oil and diminishing its lubricating properties, which lowers oil pressure and makes it harder to form a protective lubricating film on engine components. Simultaneously, metal parts expand significantly due to heat, reducing normal clearances between components. These factors accelerate wear and tear, severely impacting the engine's lifespan. 4. Fuel system vapor lock: Higher temperatures increase the likelihood of vapor lock in the engine compartment. When the fuel system heats up, some gasoline evaporates into gas within the fuel lines and pump, not only increasing flow resistance but also, due to the compressibility of gas, causing fuel vapor in the pump's outlet line to compress and expand with the pump's pulsating pressure. This disrupts the vacuum created during the pump's suction phase, leading to insufficient or interrupted fuel supply—a condition known as vapor lock. This phenomenon is more common in hot climates, especially when the vehicle is fully loaded climbing hills or driving at low speeds for extended periods. 5. Ignition system malfunction: In high-temperature environments, the ignition coil may overheat, weakening the high-voltage spark and causing engine misfires at high speeds. In severe cases, the ignition coil may burn out, affecting normal vehicle operation.

Is the purchase invoice required for the first maintenance?

The purchase invoice is required for the first maintenance. The items needed for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice. Bring these to the designated first maintenance facility for the vehicle's first maintenance. Note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial maintenance after the new car has been driven. The specific time varies by car, usually after driving 1,000 to 3,000 kilometers. The car needs to undergo the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven according to the standard load and normal speed required by the car. The time for the first maintenance is calculated based on the date the car was picked up. There are two indicator values for the first maintenance time: mileage and time. Whichever comes first will be the standard. The first maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various oil levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and inspecting tires for damage or bulges. Required time: Completing all tasks takes about 2 hours. The most important aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must also be replaced. The selection of engine oil must refer to the "Vehicle User Maintenance Manual," as different car models specify different engine oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, using water to wash the body and wiping it with a cloth. It is important to note that the interior of the car body should not be directly rinsed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush and clean with detergent, dry them, and then put them back. There are many holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry but flow through these holes to parts like the gearbox, causing erosion and corrosion. The best practice is to use a vacuum cleaner for cleaning and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze first and then add the same brand of antifreeze. Since antifreeze brands differ, their chemical properties vary greatly. Various functional additives may corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When the bolts on a moving car rust, they are often oiled to function properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricant to them, which can pose a safety risk. When the car is driven at high speed, the bolts and nuts may loosen or even fall off, leading to driving malfunctions. Do not press the accelerator when starting an EFI car: The starter of an EFI car is different from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
