What do the China 1, China 2, China 3, China 4, and China 5 labels mean?

The China 1, China 2, China 3, China 4, and China 5 labels refer to the green environmental protection marks for motor vehicles that comply with the corresponding emission standards. These labels are typically affixed next to the A-pillar on the co-driver's side of the vehicle's windshield. Currently, China is implementing the China 5 and China 6 emission standards, so new vehicles must meet these standards to be sold. In contrast to the green environmental protection mark, there is the yellow environmental protection mark, commonly known as the 'yellow-label vehicle.' The yellow label is issued when a vehicle's emissions fail to meet the minimum requirements during the annual inspection. Yellow-label vehicles are restricted from entering many urban areas and can only operate on suburban or rural roads. The China 1, China 2, China 3, China 4, and China 5 labels correspond to the Roman numerals China I, China II, China III, China IV, and China V, respectively. The upcoming China 6 standard is denoted as China VI. The dedicated environmental protection labels have now been abolished, with emission inspections integrated into the annual inspection process, represented by the annual inspection compliance mark. The implementation of China 6 means that vehicles meeting the China 5 standard can no longer be sold, resold, or transferred, but it does not affect their normal operation. The only vehicles significantly impacted are those meeting the China 3 standard, which are restricted from entering urban areas. Due to these restrictions, China 3 vehicles are often left with no option but to be scrapped.

Shift Mechanism

Shift mechanisms can be divided into two types: direct control and remote control. Direct control: In this configuration, the transmission is located near the driver's seat, and the shift lever extends from the floor of the cab, allowing the driver to operate it directly. This type is commonly used in front-engine, rear-wheel-drive vehicles. Remote control: When the transmission is far from the driver's seat, auxiliary levers or a set of linkage mechanisms are added between the shift lever and the shift fork to form a remote control mechanism. This type is often used in front-engine, front-wheel-drive vehicles, as their transmissions are installed near the front drive axle, which is far from the driver's seat, necessitating this control method.

How far can a car generally go when the fuel gauge reaches the red line?

How far a car can generally go when the fuel gauge reaches the red line depends on the specific model. Typically, when the fuel gauge needle reaches the red line, there is still about 10% of fuel left in the tank, allowing the car to travel an average of 20 to 60 kilometers further. When the fuel gauge is approaching the red line, it is advisable to refuel in advance, which is more beneficial for the vehicle's usage. If you continue driving without refueling after reaching the red line, it may lead to the fuel pump burning out. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from the distillation, cracking, or pyrolysis of petroleum. It is used as fuel and appears as a transparent, flammable liquid.

What impact does water ingress into spark plugs have on the engine?

Water ingress into spark plugs does not affect the vehicle as long as the engine starts normally. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage into the combustion chamber, causing it to jump across the electrode gap to generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. The spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. Under high voltage, the air between the center electrode and side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. A discharge channel forms across the gap, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2000-3000°C, sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.
