What is Engine Cylinder Scoring?

Engine cylinder scoring refers to the phenomenon where the piston and piston rings, during their reciprocating motion within the cylinder, forcibly scrape and create noticeable scratches and grooves on the cylinder wall due to poor lubrication or excessively small clearance between components. Below is an introduction to engine cylinder scoring: 1. Symptoms and sounds of engine cylinder scoring: (1) The engine temperature rises, the RPM becomes unstable, there are signs of stalling, and a "clicking" sound is emitted simultaneously. (2) When the engine experiences cylinder scoring, the main symptoms while driving include weak acceleration and abnormal jerking. 2. Causes of engine cylinder scoring: (1) Overheating engine: Overheating is one of the most common causes of cylinder scoring. When the engine temperature is too high, it disrupts the balance of clearance between the piston, piston rings, and cylinder, leading to cylinder scoring. In severe cases, it may even cause the piston to seize directly within the cylinder. (2) Poor oil lubrication: Generally, engine cylinders are lubricated through splash lubrication, and some engines may also be equipped with dedicated cylinder lubrication injectors. If the oil level is too low, the injector is clogged, or the oil pressure is too low, it is highly likely to result in cylinder scoring. (3) Carbon buildup issue: When carbon deposits accumulated in the cylinder fall into the gap between the piston and cylinder, the reciprocating motion of the piston can forcibly cause scratches and marks on the cylinder wall.

Is Driving in Heavy Rain Harmful to the Car?

Generally, during normal rain, it is still necessary to pay attention while driving, slow down, and prioritize safety. More information about cars is as follows: 1. Overview: Automotive safety for vehicles is mainly divided into two major aspects: active safety and passive safety. Active safety involves controlling the car as freely as possible. Whether braking and accelerating in a straight line or turning left and right, it should be as smooth as possible to avoid deviating from the intended path and not affecting the driver's vision and comfort. 2. Others: Automotive safety technology covers an increasingly wide and detailed range, developing towards integration, intelligence, systematization, and all-encompassing directions.

What Causes Electric Power Steering to Become Heavier?

Electric power steering becoming heavier can be attributed to the following reasons: 1. Low tire pressure: If you notice the steering wheel is slightly heavier than before, it's advisable to first check the tire pressure. Sometimes, low tire pressure can also cause the steering wheel to become heavier, making it harder to turn. 2. Low vehicle speed naturally makes the steering heavier: Whether the steering wheel becomes heavier depends on its relation to vehicle speed. The assistance level of the electric power steering system is inversely proportional to the vehicle speed—it's heavier at high speeds and lighter at low speeds. Moreover, it only operates when steering, which helps reduce fuel consumption. If it's confirmed to be related to vehicle speed, this is normal. 3. Vehicle battery discharge: The energy for the electric power steering system's motor comes from the battery or the engine. Energy from the motor is only required during steering operations. If the car battery has been used for a long time, it might affect the normal output of the electric power assistance. The lifespan of a car battery is typically around 3-5 years. Batteries used for more than 3 years should be replaced promptly when necessary. 4. If it's confirmed that the issue is unrelated to vehicle speed and both tire pressure and battery are normal, it's recommended to visit a professional auto repair shop or 4S store for inspection. It's likely that the electric power steering system itself has developed a problem, such as overly tight bearings or poor lubrication.

Does the car transmission fluid need to be replaced?

Transmission fluid needs to be replaced. Here is the relevant information about transmission fluid replacement: 1. Dry dual-clutch transmissions and manual transmissions have similar structures, so they both use synthetic transmission fluid with a service life of approximately 150,000 kilometers. Most automatic transmissions require fluid replacement every 60,000 to 80,000 kilometers. 2. The transmission fluid replacement cycle is just a general guideline. Due to factors such as driving conditions and habits, the condition of the transmission fluid may vary. If the vehicle experiences issues like rough shifting, strong jerking sensations, or significantly increased noise during use, it is necessary to check whether the transmission fluid needs replacement. 3. There are three common methods for replacing transmission fluid in vehicles: (1) Gravity drain: Similar to changing engine oil, the transmission fluid drain bolt is loosened to drain the fluid, and then new fluid is added through the fill port. The drawback is that gravity draining does not completely remove all the old fluid. (2) Machine flush: A transmission flush machine is connected to the transmission's fluid lines, and new fluid is added to the machine. The new fluid is then used to "push" out the old fluid from the transmission. The advantage is a thorough replacement, but the process is time-consuming and requires more transmission fluid. (3) Removing the transmission pan: The advantage is that the transmission filter can be cleaned or replaced directly, and the replacement is more thorough. The downside is that the procedure is more complicated.

Can Reducing Tire Pressure Prevent Blowouts?

No. Here are specific details about tire pressure: 1. Low tire pressure increases the contact area with the ground, causing excessive deformation of the cord ply and raising tire temperature. Under intense deformation, the inner airtight layer generates extreme heat, leading to rubber and cord ply separation, drastically increasing blowout risks. 2. Tire pressure affects not only the contact area and position with the ground but also the tire's shape, particularly the sidewall - the weakest part. 3. When the sidewall contacts the ground, it deforms, causing unstable rotation during driving. With insufficient pressure, tires undergo irregular multidirectional deformation on roads. Continuous compression and friction on the cord ply can cause fractures, forming bulges until a blowout occurs.

How Thick Should Homemade Car Jumper Cables Be?

For general household cars, it is recommended to use copper wires with an outer diameter of 10mm or more. Here is the relevant information: 1. Introduction: Car jumper cables are usually about 3 meters long, not too long as increased resistance will consume power; nor too short, as it will be difficult to connect. 2. Function: When a car battery is low on power, it affects the entire vehicle's power supply system, making it difficult to start the car. If the car stalls midway and cannot be restarted, calling for a tow truck can be expensive. In such cases, jumper cables from another car can be used for emergency assistance. If the battery is low on power, the car should start quickly. After starting, keep the engine running for 15 to 20 minutes to allow the alternator to recharge the battery.
