Automobile performance degradation mechanisms can generally be categorized into tangible wear and intangible wear: I. Tangible wear can be divided into the first type of tangible wear and the second type of tangible wear: 1. The first type of tangible wear refers to the loss caused by the decline in automobile performance due to damage such as friction wear, deformation, and fatigue of components under load; 2. The second type of tangible wear refers to the chemical and electrochemical interactions between components and external media during idle periods, leading to corrosion of metal parts, aging and deterioration of non-metallic products, and even loss of functionality. II. Intangible wear can also be divided into the first type of intangible wear and the second type of intangible wear: 1. The first type of intangible wear refers to the devaluation of the original automobile due to advancements in science and technology, which reduce the reproduction cost of automobiles with the same structure (same model); 2. The second type of intangible wear refers to the devaluation of the original automobile due to advancements in science and technology, which lead to the production of new automobiles with more advanced and efficient performance.

I've discussed this issue with some car-savvy friends, and there are actually many reasons for a car's performance to deteriorate. It's mainly due to the wear and aging of various components over time and use. For example, the piston rings and cylinder walls of the engine gradually wear out, leading to a drop in compression pressure and reduced ignition efficiency, making the car feel sluggish and slower to accelerate. Then there's the transmission system—aging oil seals in automatic transmissions can cause leaks, and gear wear can make shifting less smooth. The suspension system is even more noticeable; when shock absorbers fatigue and lose their elasticity, the ride becomes bumpy over rough roads, and handling deteriorates. The electrical system is also a problem—when the battery reaches the end of its lifespan, starting becomes slow, and corroded wiring can cause poor contact. I think all these factors add up, and if you neglect regular oil and filter changes, sludge buildup makes the engine more prone to failure. Ultimately, performance declines steadily, fuel consumption rises, and it’s really heartbreaking.

How to Drive Safely on Muddy Roads?

On muddy roads, it's advisable to drive at medium to low speeds, as this allows the engine to deliver greater torque. Additionally, avoid shifting gears while driving on muddy surfaces. When pressing the accelerator pedal, the vehicle may stop due to excessive resistance, and restarting on a muddy road can be challenging. If you notice one of the tires slipping on the muddy road, gently apply the handbrake and increase the throttle. This action stops the slipping tire from spinning while increasing the driving force on the other wheel, potentially helping the vehicle to move out of the mud. However, when stuck in mud, many drivers instinctively press the accelerator to gain speed, but this often makes it harder to pass through. This is because engine torque follows a curve—it increases with RPM up to a certain point, then decreases as speed continues to rise. On slippery uphill roads, sudden acceleration or braking can cause wheel slippage. When descending, never coast in neutral; instead, maintain an appropriate gear based on your speed. If braking is necessary, apply light and continuous pressure on the pedal to avoid overheating the brake pads and discs, which can reduce braking efficiency. When driving on unpaved roads (other than asphalt or concrete), tire slippage is often caused by excessive or abrupt acceleration, heavy braking, or high speeds on curved sections.

What Causes Uneven Tire Wear?

The phenomenon of uneven tire wear is characterized by severe wear on both sides, no side wear, or wave-like wear. Different phenomena require different solutions. If both edges of a tire show regular and roughly equal severe wear (excluding leaf spring issues), it is usually caused by insufficient tire pressure. Solution: Check and replenish tire pressure. If the tire wears evenly but excessively, without side wear or wave-like wear, common causes include: poor road conditions, unsuitable tread patterns for specific surfaces; improper user maintenance, mixed tire installation, or lack of timely rotation (timely rotation can extend mileage by 20%); severe overloading, causing excessive tire stress; higher environmental temperatures leading to shorter tire lifespan. Solution: Replace with qualified tires. Regular wheel alignment: Wheel alignment enhances driving safety, extends tire lifespan, reduces fuel consumption, minimizes tire wear (avoiding uneven wear), and decreases suspension component wear. Therefore, it is essential to have wheel alignment done periodically at a 4S shop or professional repair facility. It is recommended to perform this at least once a year or every 10,000 kilometers. Adjust tire pressure: Note that both overinflation and underinflation can cause uneven tire wear. Underinflation causes the tire to bend inward, leading to severe edge wear, while overinflation accelerates wear on the center of the tread. Thus, regularly monitor tire pressure to ensure it remains at the normal level. Generally, inflate or deflate according to the vehicle's specified tire pressure.

What to Do When the Brakes Become Hard with Air Conditioning On in a Car?

If the brakes become hard when the air conditioning is on in a car, it should be sent to a 4S shop for repair as soon as possible. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, belts, or discs on the machine base to generate braking torque under external force. The braking device is a mechanical braking device that can slow down the speed, also known as a decelerator. Reasons why the brakes become hard after turning on the air conditioning: After turning on the air conditioning, the engine load increases, the throttle vacuum decreases, and the brake vacuum assistance reduces, making the brake pedal hard to press. If there is a problem with the brake vacuum system, turning on the air conditioning consumes a large amount of vacuum, so the brake vacuum assistance does not work, making the pedal feel hard. This issue should be resolved as soon as possible, as it can be dangerous in emergencies. The car should be sent to a 4S shop for maintenance and repair promptly. The function of the brakes is to decelerate, either by reducing speed or bringing the vehicle to a stop. The principle of braking is to convert the kinetic energy of the car into heat energy, which is then dissipated. The kinetic energy comes from the power provided by the engine, which requires fuel combustion to generate work.
