What is the difference between a D license and a C1 license?

The difference between a D license and a C1 license lies in the completely different types of vehicles they authorize to drive. A D license allows driving all types of three-wheeled motorcycles and two-wheeled motorcycles; a C1 license permits driving all types of small passenger vehicles, which are essentially family cars. There is no compatibility between the two. Vehicles authorized for C1 license: The scope of a C1 driver's license includes small and mini passenger vehicles, light and mini cargo vehicles, and light, small, and mini special-purpose vehicles. Small passenger vehicles must have a seating capacity of 9 or fewer people. A C1 driver's license does not authorize driving: large buses, tractor units, city buses, medium-sized buses, large trucks, regular three-wheeled motorcycles, regular two-wheeled motorcycles, mopeds, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not permit driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

How many kilometers can you drive after the fuel gauge light comes on?

After the fuel gauge light comes on, you can generally drive approximately 40-60 kilometers. Below is more information about the fuel gauge light: 1. Introduction: The fuel gauge light is one of the essential components in a car, used to monitor the remaining fuel quantity in the fuel tank. 2. Consequences: Driving until the car runs out of fuel can cause damage to the vehicle, potentially harming the fuel pump. 3. Refueling: When refueling the car, avoid filling the tank too full. In high-temperature summer environments, gasoline can evaporate into vapor, and with no extra storage space in the tank, this not only pollutes the environment but also increases the car's fuel consumption. In winter, overfilling the tank can damage the car and fill the interior with the smell of fuel, affecting human health. There is also a risk of danger if exposed to open flames. It is generally recommended to refuel when the fuel level drops to one-quarter and to fill the tank to only 80%-90% capacity.

What is the reason for the EA888 reporting a knock signal that is too small?

EA888 reporting a knock signal that is too small may be caused by poor fuel quality, fuel line issues, high engine operating temperature, sensor problems, sensor wiring faults, or the need for an engine computer upgrade or repair/replacement. Below are specific details about knock sensors: 1. There are many types of knock sensors, with the magnetostrictive knock sensor being the earliest type used, mainly composed of a magnetic core, permanent magnet, and induction coil. When the engine vibrates, the magnetic core shifts due to vibration, changing the magnetic flux within the induction coil and generating an induced electromotive force in the coil. 2. Other types, such as piezoelectric ceramic sensors, generate an electrical signal when the ceramic inside is squeezed due to engine vibration. Because this electrical signal is very weak, the connecting wires of knock sensors are usually wrapped with shielded cables.

When Will China 6 Vehicles Be Available?

As early as 2019, some automakers began producing China 6 models. By mid-2020, all automakers had ceased production of China 5 models, and all newly launched models were China 6 compliant. More information about China 6 emissions is as follows: 1. China 6 Emission Standards: The emission limits for China 6A are: carbon monoxide 700mg/km, non-methane hydrocarbons 68mg/km, nitrogen oxides 60mg/km, PM fine particles 4.5mg/km, etc.; China 6B: carbon monoxide 500mg/km, non-methane hydrocarbons 35mg/km, nitrogen oxides 35mg/km, PM fine particles 3mg/km, etc. 2. Impact After Implementation: After the implementation of the China 6 standard, it will only affect the registration of new China 5 vehicles. Already registered and annually inspected China 5 vehicles will not be affected in normal use.

What is the torque specification for connecting rod bearing bolts?

Automotive cylinder head connecting rod cap bolts require 8 Nm torque for the main bearing caps and 6 Nm torque for the small bearing caps. Below are specific details about connecting rod cap bolts: 1. Engine compression ratios vary across different vehicle models, resulting in different bolt torque specifications. You can use a torque wrench to measure the N/m value when removing the bolts. 2. Classification by connection force method: ordinary and reamed hole. Classification by head shape: hexagonal head, round head, square head, countersunk head, etc. Hexagonal heads are most commonly used, while countersunk heads are typically used where flush connections are required. 3. Thread types are divided into coarse and fine threads, with coarse threads not displayed in bolt markings. Bolts are classified into eight performance grades: 3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9.

Why is the tire pressure of the left front tire lower than the other three?

It may be due to a slow leak in the underinflated tire, causing the pressure to naturally decrease over time. Alternatively, the tire might have been punctured by a nail, leading to air leakage. When low tire pressure is detected, it should be promptly inspected and repaired or replaced to prevent safety hazards. What to do if the tire pressure is insufficient: If no visible damage is found, simply inflate the tire to the normal pressure and reset the tire pressure system. If a puncture is discovered during inspection, drive to a tire shop immediately for repair, then reinflate the tire. If the tire pressure warning reappears after inflation but there is no puncture, it might be due to a leaking rim caused by deformation. In this case, check the rim and consider replacing it. According to the international GBT2978-2008 standard, the recommended tire pressures are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure should not exceed 3.5bar.
