When a car displays a transmission failure, it is often due to a malfunction in the power electronic control system, possibly caused by a faulty connection in one of the transmission sensor circuits. Below is an introduction to the transmission system: 1. Main Functions: To alter the transmission ratio, expanding the range of torque and rotational speed variations of the drive wheels to adapt to frequently changing driving conditions, while ensuring the engine operates under favorable conditions. It allows the car to reverse without changing the engine's rotational direction. By utilizing neutral gear, it interrupts power transmission, enabling the engine to start, shift gears, and facilitating gear changes or power output. 2. Working Principle: A manual transmission primarily consists of gears and shafts, achieving speed and torque variations through different gear combinations. An automatic transmission (AT), on the other hand, is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variations through hydraulic power transmission and gear combinations.

Why is the tire pressure always lower than others after repairing the Verano tire?

If the tire pressure of the Verano is always lower than others after repair, you can try replacing the valve stem. Tire pressure, strictly speaking, refers to the air pressure inside the tire. Insufficient tire pressure: If no damage is visible, you can directly inflate the tire to the normal pressure and reset the tire pressure system. If the tire is found to be punctured during inspection, drive to a tire shop promptly for repair and then reinflate. If the tire pressure warning appears again after inflation but there is no puncture, it may be due to air leakage caused by a deformed wheel rim. It is recommended to inspect the wheel rim and replace it if necessary. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; causes heavy steering and potential alignment issues, affecting driving safety; increases movement in various parts of the tire, leading to abnormal heat generation due to excessive rolling; reduces the functionality of the tire cords and rubber, potentially causing delamination or cord breakage, as well as excessive friction between the tire and rim, resulting in damage and abnormal wear at the bead area.

What is the normal tire pressure range for BMW cars?

The normal tire pressure for BMW is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data complies with the international GBT2978-2008 standard. You can find the specified tire inflation pressure data on the door pillar by opening the driver's side door. A pressure gauge can be used to check the tire pressure. Generally, a tire pressure exceeding 2.8bar is considered too high, while a pressure below 2.0bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies the friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually alerts when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system records the previous data, causing the indicator light to come on. Simply reset the tire pressure in this case. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged by impact during driving, the tire pressure warning light will come on. For sensor damage, replacement with a new part is the only solution.

What Causes Sudden Shaking When Accelerating Hard?

The reasons for sudden shaking when accelerating hard: 1. Damaged spark plugs - excessive gap wear leads to insufficient sparking, incomplete combustion of air-fuel mixture, or cracked ceramic parts causing misfires; 2. Poor fuel quality resulting in inadequate fuel injector atomization and incomplete combustion; 3. Uneven tire tread wear including bulges, foreign objects or loose wheel bearings; 4. Engine mechanical issues causing uneven cylinder pressure; 5. Fuel system problems where injectors fail to seal properly or get clogged due to excessive carbon buildup.

What Components Make Up a Car Suspension System?

An automobile suspension system consists of elastic elements, guiding mechanisms, and shock absorbers, with some suspensions additionally including buffer blocks and anti-roll bars. The elastic elements encompass various forms such as leaf springs, air springs, coil springs, and torsion bar springs. Modern passenger cars predominantly utilize coil springs and torsion bar springs, while premium luxury coaches employ air springs. Typically referring to independent suspensions, car suspensions serve as crucial components ensuring ride comfort. Simultaneously, functioning as force-transmitting connectors between the frame/body and axles/wheels, they represent one of the vital safety-critical systems enabling proper vehicle operation.

What are the penalties for motor vehicles not driving in the designated lane?

According to the Road Traffic Safety Law, drivers who fail to drive in the designated lane will be fined and have three points deducted from their driving license. When approaching a traffic signal intersection, drivers should change lanes in advance to avoid the danger caused by not following the designated lane. The directional lane markings are designed to guide vehicles in the correct direction at intersections. Such markings are commonly found at busy intersections to clarify the direction of travel, ensure orderly traffic flow, and reduce congestion. A variable lane, indicated by multiple diagonal lines on the side, is a lane that can change its direction based on real-time traffic flow.

What is the solution when the car battery is dead due to leaving the headlights on?

The solution when the car battery is dead due to leaving the headlights on is: use jumper cables to connect the battery to the car for charging. The impacts of a dead car battery include: 1. Affecting the battery's lifespan, frequent power loss will shorten its service time; 2. Preventing the car from starting, making the vehicle unusable and causing other electrical devices in the car to malfunction; 3. During startup, it may cause data loss in the vehicle's control modules, leading to operational failure; 4. Overheating the starter motor and reducing its lifespan; 5. Forcing the alternator to operate under heavy load after starting, prolonged power deficiency may damage the alternator.
