How to Handle After a C1 Driver's License is Deducted 12 Points?

Are there any clothing requirements for driver's license photos?

There are no strict requirements on clothing color for driver's license photos in principle, but wearing bright-colored clothes is recommended. Below is some information about the driver's license test: 1. Subject 1: Road traffic safety laws, regulations and related knowledge test. Written exam, computer-based, full score of 100, passing score is 90 or above (including 90). 2. Subject 2: Field driving skills test. Practical test in enclosed area, pass/fail only. Includes five mandatory tests conducted in sequence: reverse parking, parallel parking, S-curve, right-angle turn, and hill start. Full score of 100, passing score is 80 or above (including 80). 3. Subject 3: Road driving skills test. Practical test on roads or simulated environment. Full score of 100, passing scores vary: 90+ for large buses, 80+ for large trucks, 70+ for other vehicle types. 4. Subject 4: Safety and civilized driving knowledge. Written exam, full score of 100, passing score is 90 or above (including 90).

What Causes Intermittent Air Conditioning Failure in a Land Rover Range Rover?

Reasons for intermittent air conditioning failure in a Land Rover Range Rover: 1. Excessive Refrigerant: Leads to reduced cooling efficiency. Excessive impurities in the refrigerant and refrigeration oil can cause minor blockages, resulting in insufficient cooling capacity. 2. Insufficient Refrigerant: Inadequate refrigerant leads to insufficient cooling capacity. A dirty condenser or a loose compressor drive belt can also cause the air conditioning to blow warm air. 3. Excessive Impurities: High levels of impurities in the refrigerant and refrigeration oil can cause minor blockages, leading to insufficient cooling capacity. If there are too many contaminants in the entire air conditioning system, the filter screen will inevitably become clogged, reducing the refrigerant flow capacity, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, thus resulting in insufficient cooling capacity.

To What Extent is a Car Considered Flooded?

It refers to motor vehicles where the water immersion depth exceeds one-fourth of the wheel height, and the bottom components of the body are in prolonged contact with water. Below are the relevant details: 1. Flooded vehicles: Depending on the extent of water immersion, a car is considered flooded if the water level exceeds the chassis, partially flooded if it surpasses the oil dipstick, and fully flooded if it reaches above the engine hood or dashboard. Generally, the first scenario, where only the bottom of the body is in prolonged contact with water, has minimal impact on normal vehicle usage. The latter two scenarios, however, are entirely different, as they can easily lead to rusting of body components, shortened lifespan, and reduced safety performance. If the vehicle's wiring corrodes or rusts, it may cause sudden engine shutdown due to short circuits while driving, with potentially unimaginable consequences. 2. Repair: Flooded cars can be repaired to some extent, but due to the susceptibility of internal gears, belts, and other components to corrosion, and the fact that engine equipment is not waterproof, the long-term effects of water damage are unpredictable.

Will the Engine Stall if You Slam on the Brakes?

Slamming on the brakes can cause the engine to stall. The reason for the engine stalling when braking is due to the excessive braking force, which prevents the engine and transmission from disengaging in time. For automatic transmission vehicles, it might be caused by a damaged idle speed stabilizer valve, directly resulting in the idle speed being uncontrolled and unable to maintain normal operation. The reasons for brake noise without braking are as follows: 1. Use of low-quality or overly hard brake pads: If low-quality or overly hard brake pads are used, they will produce a squeaking sound when rubbing against the brake disc during braking. Therefore, it is essential to use high-quality brake pads when replacing them. 2. Presence of sand or foreign objects between the brake pad and brake disc: During normal driving, it is inevitable to pass through some complex road conditions. Due to the unique design of disc brakes, some sand and foreign objects may get between the brake pad and brake disc, causing noise during braking.

How to Solve the Problem of a Battery Not Charging After Long-Term Storage?

Here are the reasons and solutions for an electric vehicle battery not charging: 1. Light sulfation: Perform balanced charging. You can carry out general activation charging (i.e., balanced charging) on the battery, usually lasting one to two days, to restore normal function. 2. Moderate sulfation: Perform "hydrotherapy" charging and discharging. "Hydrotherapy" charging and discharging is required to restore normal function. The specific method involves first adding pure water or dilute sulfuric acid with a density of 1.05g/cm3 to the battery until it reaches a liquid-rich state, then charging with a current of 0.05-0.018C2A for about 20 hours, draining the liquid, and then conducting a capacity test. Repeat the above steps until the battery capacity is restored. 3. Severe sulfation: Use a repair device. If the battery is severely sulfated, ordinary repair methods will no longer work. You can use the high-resistance repair function of a repair device to increase the voltage to above 10V before charging again, which may have a certain probability of reactivating the battery.

What is the truth about the Speedmaster fuel catalyst?

Speedmaster fuel catalyst has some scientific basis for improving car performance, but these metal-rich particles can cause certain damage or effects on spark plugs, three-way catalytic converters, and engines. Benefits of the Speedmaster fuel catalyst: 1. More active fuel molecules: The Speedmaster fuel catalyst can make fuel molecules more active, allowing about 90% of the gasoline to fully combust in the cylinder within a short time. This results in relatively more work done during the explosion stroke, stronger crankshaft power, and increased mechanical energy. 2. Strong anti-knock properties: High-end cars with large cylinder compression ratios require higher-grade gasoline. The Speedmaster fuel catalyst creates a low-temperature working environment inside the engine cylinder, making it less likely for low-grade oil to produce high-temperature thermal compression combustion in high-compression-ratio engine cylinders. The fuel molecules inside the cylinder are more stable and controllable, with strong anti-knock properties. 3. Environmental protection: From an environmental perspective, Speedmaster injects new vitality into automotive fuel. During operation, the fuel's molecular activity is enhanced, allowing for full combustion and significantly reducing the emission of harmful substances in vehicle exhaust, thereby achieving energy-saving and emission-reducing environmental benefits.
