What Causes Valve Leakage?

Valve leakage can be caused by the following reasons: 1. Wear and burning of the valve and valve seat working surfaces, leading to spots, pits, or carbon deposits. 2. Excessive clearance between the valve stem and the valve guide sleeve, causing the valve stem to wobble. 3. Weakening or loss of elasticity in the valve spring, or spring breakage. 4. Factors such as excessively small valve clearance. Additional related information is as follows: 1. The car valve, also known as the throttle, is responsible for introducing fuel into the engine and expelling exhaust gases. Traditional engines have only one intake valve and one exhaust valve per cylinder. This design is relatively simple, cost-effective, easy to maintain, and performs well at low speeds. However, its drawback is difficulty in increasing power, especially due to low charging efficiency and weaker performance at high speeds. 2. To improve intake and exhaust efficiency, multi-valve technology is now commonly used, with each cylinder typically having four valves (some designs feature three or five valves per cylinder, following the same principle, such as in the Audi A6 engine). A four-cylinder engine thus has a total of 16 valves, often denoted as "16V" in car specifications, indicating the engine has 16 valves in total.

What are the differences between Paladin and Odin?

Paladin and Odin differ in the following aspects: Different engine displacements: The Paladin only comes with two engine options: 2.4L and 3.3L, both of which are imported gasoline engines. In contrast, the "Odin" offers three engine choices including 2.4L, 3.0L, and 3.2L, featuring both domestically produced and imported gasoline and diesel engines. Different suspensions: The "Odin" inherits the Paladin's double-wishbone independent front suspension, but its rear suspension is changed to a five-link coil spring non-independent type, enhancing comfort. Different models: The "Odin" is available in both manual transmission and automatic transmission variants. Different performance characteristics: The "Odin" embodies typical urban SUV features, such as 2WD automatic transmission, electronic 4WD switching, and exterior styling more suited for city use. Optional features like visual parking sensors and an electronic compass are also available.

What happens if a car that requires 95-octane gasoline is filled with 92-octane?

It is generally not recommended to mix gasoline of different octane ratings. If a car designed for 95-octane gasoline is filled with 92-octane, the following issues may occur: 1. The vehicle may experience insufficient power and increased fuel consumption; 2. This can further lead to accelerated wear and damage of engine components, triggering the engine fault warning light; 3. Some vehicles may stall and fail to start. Below are some related details about mixing gasoline: 1. Mixing lower-octane gasoline into a higher-octane vehicle: (1) This may cause engine knocking, leading to overloading and damage to components such as pistons, connecting rods, and cylinder heads; (2) The engine may overheat, causing more combustion byproducts to decompose, increasing exhaust temperature, reducing engine power, and increasing fuel consumption; (3) Elevated engine temperature may result in poor lubrication of moving parts, leading to abnormal wear. 2. Mixing higher-octane gasoline into a lower-octane vehicle: (1) This may cause delayed combustion, ultimately leading to incomplete fuel combustion, increased carbon deposits in the engine, and engine damage.

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.
