What is the Appropriate Torque for Spark Plugs?

For 12mm spark plugs, the generally applicable torque is 20 to 25 Nm, while for 14mm spark plugs, it is typically 25 to 30 Nm. What is a Spark Plug: A spark plug is a crucial component in the ignition system of a gasoline engine. It introduces high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. Components of a Spark Plug: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. How a Spark Plug Works: Under high voltage, the air between the center electrode and the 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 and forming a discharge channel, resulting in a 'breakdown' phenomenon. At this point, the gas becomes a luminous body, known as a 'spark.' Along with the thermal expansion, a 'crackling' sound is also produced. The temperature of this electric spark can reach as high as 2000-3000°C, sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.

To retain the license plate number after vehicle scrapping, apply to the vehicle management office within six months after completing the transfer registration or cancellation registration. To apply for using the original motor vehicle license plate number, the following conditions must be met: Submit the application within six months after completing the transfer registration or cancellation registration; the motor vehicle owner has owned the original motor vehicle for more than three years; all road traffic violations and accident handling related to the original motor vehicle have been completed. Motor vehicle registration regulations: According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the motor vehicle transfer registration or cancellation registration, the original motor vehicle owner can apply to the vehicle management office to use the original motor vehicle license plate number when registering a newly purchased motor vehicle. Notes on vehicle transfer: Transfer registration time: The original license plate has been used for more than one year, and the motor vehicle owner has owned the original motor vehicle for more than three years. The application must be submitted within 6 months after completing the transfer registration or cancellation registration. Conditions for applying to retain the original license plate: When the vehicle is transferred, canceled, or relocated, and when purchasing a new or used car, you can apply to retain the original license plate. All road traffic violations and accident handling must be completed. Surrendering old plates: If you do not want to use the old license plate, the old plate must be surrendered. If it is not used within one year, it will be recycled into the number resource pool. The vehicle management office can periodically release numbers when the number source is insufficient.

What Causes Abnormal Noise and Failure to Start in the Starter?

Starter abnormal noise and failure to start are caused by battery power deficiency, motor malfunction, and excessive carbon buildup. The specific reasons and solutions for starter abnormal noise and failure to start are as follows: Specific reasons for starter abnormal noise and failure to start: Battery power deficiency: Insufficient voltage in the car battery. When the battery power is insufficient, it cannot drive the engine to reach the starting speed. The clicking sound during startup is due to the repeated engagement between the solenoid and the relay. Motor malfunction: Severe oxidation of the starting connection metal block in the motor control mechanism, resulting in poor starting contact. Excessive carbon buildup: Too much carbon buildup in the intake pipe, throttle valve, idle motor, and other parts can prevent the engine mixture from reaching the required air-fuel ratio, causing the vehicle to fail to start. This can also lead to the clicking sound of the solenoid and starter relay engaging. Solutions for starter abnormal noise and failure to start: Replace the battery; replace the severely worn motor starting gear and the connection metal block; clean the carbon buildup.

Can a motorcycle still be inspected after 6 years of overdue inspection?

A motorcycle that has not been inspected for 6 years cannot participate in the annual inspection. If a motorcycle has not been inspected for 3 consecutive inspection cycles, it will be deregistered. Driving a vehicle with an overdue inspection is illegal and may result in a warning from the public security traffic management department. Motorcycle inspection schedule: For motorcycles within 6 years of registration, inspection must be applied for every 2 years at the public security traffic management department to obtain the inspection compliance label; motorcycles over 6 years old must be inspected annually. Motorcycle inspection process: For the motorcycle inspection, basic identification documents must be brought, and the motorcycle must be driven to the designated vehicle inspection site on a working day for registration and inspection. The motorcycle inspection mainly covers three aspects: the braking system, the lighting system, and exhaust emissions. Motorcycle overdue inspection: If the motorcycle inspection is overdue for less than 3 months, it can be directly rectified, usually with a verbal warning; if overdue for more than 3 months but less than 2 years, rectification may involve an unspecified fine. If the inspection is overdue for more than 2 years, the vehicle's registration will be directly canceled. Once the inspection is overdue, the vehicle owner will be fully liable for any accidents.

What is the Difference Between Commercial and Non-commercial Vehicles?

Commercial and non-commercial vehicles are primarily distinguished by whether they are used for profit-making purposes. A commercial motor vehicle refers to a vehicle engaged in road transport operations for profit-making purposes, meaning it generates and obtains economic benefits through transport activities related to business operations. Examples include taxis, chartered minibuses, private large dump trucks, and small trucks. In short, commercial motor vehicles are those used for profit-making purposes, such as transporting passengers or goods. Non-commercial motor vehicles are those not used for profit-making purposes. Generally, private cars and company-owned vehicles fall under this category. Non-commercial vehicles cannot participate in commercial transport activities. The vehicle registration certificate specifies whether a vehicle is commercial or non-commercial. There are no special requirements for the driver's license, but if you drive a commercial vehicle, you must obtain a professional qualification certificate from the transport department. This is not required for non-commercial vehicles. The "use nature" section of the registration certificate for commercial vehicles will state "commercial," and the vehicle must obtain a road transport permit from the transport management department. In addition to holding a driver's license for the specific vehicle type, the driver must also obtain a professional qualification certificate. Commercial vehicles are required to pay regular transport management fees to the transport management department. Non-commercial vehicles do not incur any transport management fees and thus do not need to pay such fees. The "use nature" section of their registration certificate will state "non-commercial," and they do not require a road transport permit. Drivers only need a valid driver's license for the specific vehicle type.

How many points are deducted for not wearing a seat belt while driving?

When driving on urban expressways, if the driver fails to use the seat belt as required, they will be fined and have 2 points deducted. When driving on roads other than highways or urban expressways, if the driver fails to use the seat belt as required, they will be fined but no points will be deducted. Passengers who do not wear seat belts as required will also be fined. Below is an introduction to seat belts: Types of seat belts: high-altitude work type, semi-full-body type, bungee equipment type, and automotive type. Function of seat belts: The function of automotive seat belts is to instantly tighten and secure the loosely worn seat belt when a vehicle collision occurs or emergency braking is applied, firmly restraining the occupant in the seat to prevent secondary collisions. Once the tightening force of the seat belt exceeds a certain limit, the force-limiting device will appropriately loosen the seat belt to maintain stable chest pressure. Therefore, automotive seat belts play a role in restraining displacement and buffering, absorbing impact energy, dissipating inertial force, and avoiding or reducing the severity of injuries to drivers and passengers. Automotive accident investigations show that in frontal collisions, wearing a seat belt can reduce fatalities by 57%, in side collisions by 44%, and in rollovers by 80%.
