License plate F represents hybrid electric vehicles, while license plate D represents pure electric vehicles. Both license plates F and D are green plates, symbolizing new energy vehicles. New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources, integrating advanced technologies in vehicle power control and driving systems to form vehicles with advanced technical principles, new technologies, and novel structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices).

I've been driving for over a decade and can tell where a car is from just by looking at the license plate letters. For example, in our Guangdong Province, 'Yue F' indicates a car from Shaoguan, while 'Yue D' is from Shantou. Each province has its own numbering system, with the provincial capital usually starting with A, like 'Yue A' for Guangzhou. This rule is standardized nationwide, making it easy for traffic police to check vehicles and quickly identify their origin. However, with the rise of new energy license plates in recent years, the letters D and F have taken on additional meanings. D stands for pure electric vehicles, and F represents hybrid vehicles—a pretty scientific distinction. I remember being puzzled when I first saw plates with F, only to later learn it was part of the new rules for new energy vehicles. Whenever I spot such plates on the road, I take an extra glance, as eco-friendly models are becoming increasingly common.

Where is the Correct Position of the Steering Wheel?

The correct position of the steering wheel is in the middle directly below the car's dashboard. Here is some related information about the steering wheel: 1. Function: The steering wheel is generally connected to the steering shaft via splines, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a larger-diameter steering wheel reduces the hand force required from the driver when turning. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of steering gears, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel more reasonable in the vehicle. 2. Fault Diagnosis: Drive at a speed of 15 kilometers per hour on a relatively open road, turning the steering wheel left and right while driving to check if the steering wheel is flexible and whether there is any lack of return force. Also, observe if the vehicle veers off course when the steering wheel is released.

What Causes the Brake Pedal to Be Hard to Press When Starting the Vehicle?

The reasons why the brake pedal is hard to press when starting the vehicle are: 1. Vacuum booster pump leaks or malfunctions; 2. The brake was pressed again after the engine was turned off; 3. Too much impurity in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid, or gas resistance caused by mixing several types of brake fluid and heating, leakage in the brake master cylinder or wheel cylinder, or leakage in the air reservoir or pipeline interface. Precautions for pressing the brake while driving include: 1. When emergency braking, hold the steering wheel with both hands and avoid single-handed operation; 2. The free travel of the brake pedal directly affects braking time and distance; 3. Braking actions should be swift, and the brake pedal can be released when the vehicle skids; 4. Avoid emergency braking during high-speed turns. Braking should be appropriately done before turning, maintaining straight-line braking as much as possible to control the turning speed.

What are the materials for engine guard plates?

Engine guard plates are available in the following materials: 1. Hard plastic/resin guard plates: Relatively inexpensive with simple production processes. They can easily handle mud erosion and minor scratches to the chassis, but their overall strength is inferior to steel plates. Although they have some toughness, they can easily break under slightly severe impacts. However, this characteristic helps the engine to sink smoothly in the event of a serious accident. It should be noted that these guard plates are prone to breaking, especially in winter, and once damaged, they cannot be repaired, failing to provide long-term protection. 2. Steel plate guard plates: The advantage of steel plates is their strong impact resistance and low cost. In severe accidents, steel plates only deform and are less likely to break. However, this can interfere with the engine's safety sinking during an accident and poses a risk of damaging the engine first due to deformation during a collision, making it a double-edged sword. 3. Aluminum alloy (titanium alloy) guard plates: The advantage of aluminum alloy (titanium alloy) plates is their lighter weight compared to steel plates. However, they are more expensive, lack elasticity, can hinder engine sinking, are prone to resonance, and have lower material strength. 4. Alloy plastic steel guard plates: The characteristics of alloy plastic steel materials include light weight, high toughness, and strong pressure resistance. They also exhibit excellent physical properties such as rigidity, elasticity, corrosion resistance, and aging resistance.

What is the difference between engine displacements?

The differences between engine displacements are as follows: 1. Different maximum speeds: Different displacements result in varying maximum speeds that vehicles can achieve, also affecting their performance when fully loaded on good road surfaces. 2. Different acceleration capabilities: Different displacements lead to variations in acceleration time, performance, and distance. 3. Different climbing abilities: When facing maximum gradient slopes during driving, different displacements provide varying climbing capabilities. 4. Different fuel economies: Vehicles with different displacements offer different fuel economies, and displacement size can also reflect load-carrying capacity which relates to fuel consumption. Under the same technical level and objective conditions, larger displacements consume more fuel.

How to Remove Carbon Deposits?

Methods to remove carbon deposits are as follows: 1. Engine drip cleaning method: Cut off the fuel supply, connect the carbon deposit cleaner to the engine fuel injector, and use the cleaner to soften the carbon deposits inside the engine, which are then burned and emitted. 2. Direct disassembly cleaning method: Remove the engine intake manifold, scrape off the stubborn carbon deposits, clean them, and then reassemble the vehicle. 3. Hydrogen-oxygen carbon removal machine: The hydrogen-oxygen carbon removal machine uses machine atomization to simultaneously clean the air intake and the gasoline engine cylinder. 4. Fuel additives: Using fuel additives can effectively prevent carbon deposits and slowly remove carbon particles. However, the chemical components in the additives have certain corrosiveness. Pay attention to the product's normality and usage cycle when using it.

Can points be deducted for traffic violations processed on 12123?

12123 can handle traffic violation point deductions. Below is relevant information about vehicle violations: 1. Required documents for processing violations at the vehicle management office: original vehicle license of the violating vehicle, original ID card of the point-deducted driver, and original driver's license of the point-deducted driver. With these three documents prepared, the point-deducted driver can personally go to the vehicle management office or traffic police station service hall to take a number and queue for processing. 2. Processing time: According to traffic regulations, after a motor vehicle violation, it generally takes 3 to 7 days to query online or receive SMS notification, with a maximum delay of no more than 13 working days. The vehicle owner needs to go to the local traffic police station to handle the violation within 15 days after the violation occurs.
