What Causes Engine Gasket Oil Leakage?

There are two basic scenarios for automobile engine oil leakage. Automobile engine oil leakage: When there are clearly visible oil stains on the surface of the automobile engine casing, and if these stains reappear shortly after being cleaned, or even in severe cases where oil drips like water droplets, the vehicle should be sent for repair as soon as possible. Automobile engine oil seepage: If the engine casing only has minor oil stains, it indicates that the oil leakage is not particularly severe. The amount of seepage is minimal and hardly noticeable at this stage, posing almost no impact on the engine. The most direct and effective solution is to replace all the sealing rings. Urban traffic congestion, with frequent stops and starts, necessitates constant gear shifting. Modern vehicles have an increasing number of gears, leading to more frequent gear shifts, greater working pressure inside the transmission, higher temperatures, and accelerated aging and deformation of the rubber seals in the transmission.

What Speed is Considered Low-Speed Driving?

Generally, speeds below 30 km/h are referred to as low-speed driving. Low-speed, also known as low gear, is a commonly equipped gear in automatic transmission vehicles, marked as "L" or "1" at the bottom of the gear shift console. Essentially, it corresponds to the first gear in the transmission. Driving behavior that involves engaging low gear to pass through waterlogged roads, speed-restricted areas, or icy and snowy surfaces is termed as low-speed driving. Civilized Driving: Drivers must strictly adhere to laws and regulations while driving, consistently maintaining civilized driving and courteous road behavior. A qualified driver is not only skilled in technique but, more importantly, should possess good driving manners, habits, and moral integrity to ensure safe and civilized driving. Compliance with Traffic Regulations: Drivers should uphold traffic ethics and professional ethics, practice civilized and courteous driving, strictly comply with traffic regulations, and obey the instructions of traffic police. When driving through pedestrian crossings, bus or train stations, or busy streets with heavy traffic or crowds, drivers should slow down or stop to yield.

What is the name of the suspension that can be raised and lowered?

The suspension that can be raised and lowered is called electronic hydraulic adjustable suspension, hydraulic adjustable suspension, electromagnetic adjustable suspension, or air suspension. Electronic hydraulic adjustable suspension: Also known as Continuous Damping Control (CDC), it is a type of active suspension. This system can independently control the damping of each wheel's suspension. Its electronic sensors can read road conditions and adjust the shock absorbers in real-time, frequently switching between soft and hard settings. This allows for quicker and more accurate control of the vehicle's body roll, pitch, and yaw, enhancing stability during high-speed driving and cornering. Hydraulic adjustable suspension: This system uses hydraulic changes to adjust the vehicle's suspension. Its core component is a built-in electronic hydraulic integrated module that can adjust the frequency and extent of the shock absorbers' movement based on the vehicle's speed. Additionally, due to varying center of gravity distributions among different vehicle models, longitudinal and lateral acceleration yaw gyro sensors are typically installed near the vehicle's center of gravity. These sensors collect signals related to body vibration, wheel movement, and tilt status. The signals are processed by the vehicle's computer, which then sends corresponding execution signals to four hydraulic cylinders, adjusting the hydraulic oil volume to change the ground clearance and other parameters. Electromagnetic adjustable suspension: This suspension type uses electromagnetic reactions to adjust the vehicle's chassis height, capable of responding in an extremely short time to suppress vibrations and maintain body stability. Air suspension: It mainly consists of components such as a control computer, air pump, pressure storage tank, pneumatic front and rear shock absorbers, and an air distributor. Its primary functions are to control the vehicle's horizontal movement, adjust the body's height, and modify the stiffness of the shock absorbers.

What is the composition of transmission fluid?

Transmission fluid consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the deficiencies in the base oil's performance, endowing it with certain new characteristics, making them an essential part of lubricating oil. Hazards of not changing transmission fluid: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission's valve body. Transmission fluid and engine oil are not the same. Although both serve a lubricating function, their specific roles differ and should not be confused. Differences: Engine oil is the lubricating oil for the engine system, possessing certain properties such as oxidation resistance, wear resistance, and corrosion prevention, whereas transmission fluid is primarily used to keep the gear shift system clean and can extend the service life of internal transmission components. Because the structure and operating environment of the transmission and engine are different, transmission fluid cannot be used as engine oil, nor can engine oil be used as transmission fluid.

What is the purpose of the hole next to the motorcycle fuel tank?

The vent hole on the motorcycle fuel tank cap serves to maintain communication between the interior of the tank and the external atmosphere. During motorcycle operation, it ensures that one atmospheric pressure consistently acts on the fuel surface, guaranteeing smooth fuel delivery from the tank. If this hole becomes blocked, it can lead to fuel starvation and engine stalling while riding. Air filter connection: Even if the air filter's inlet is blocked, there are at least three other air intake points: one is the atmospheric balance hole leading to the oil reservoir, another is the bottom drain hole (which internally serves as a filtered overflow outlet), and the third is the throttle cable installation hole. This opening connects through the throttle body and isn't completely sealed. The adjustment screw at the throttle body isn't airtight either, and if there's a manual choke, none of the through-shafts are fully sealed. Important notes: If you manually block the air filter intake and start the engine, not only will it not completely prevent air intake, but it may also cause gasoline to be sucked back into your palm. This method is commonly used to enrich the fuel mixture for easier starting, particularly when dealing with carburetors that have an excessively lean mixture.

Is It Normal for a New Car's Steering Wheel to Be Loose?

It is not normal for a new car's steering wheel to be loose. The reason for the looseness may be due to steering wheel play, which is generally acceptable if it is within 15-20 degrees and not considered a fault. If the steering gear is not power-assisted, it indicates an internal issue with the steering gear, which usually requires replacing the steering gear. Introduction to the Steering Wheel: Steering wheel play refers to the free movement (also called free angle or travel) of the car's steering wheel. It is the angle the steering wheel can turn without causing the steering wheels to deviate. When the vehicle is stationary, turning the steering wheel without affecting the wheel movement is called play. This is the combined gap between the entire steering system and the steering wheels. However, this gap has a range, typically around 15-20 degrees. Beyond this 15-20 degrees, the wheels will start to turn with the steering wheel. Introduction to Steering Wheel Play: Most modern cars are equipped with steering wheel play functionality. Without this feature, the car would behave like a go-kart, where even slight turns of the steering wheel would immediately adjust the direction, especially at high speeds, making the tires prone to deviation and potentially causing safety hazards. With steering wheel play functionality, the free movement of the steering wheel can absorb the impact forces from the road surface.
