Spark plugs generally require a torque of 25-30 N/m. Here is some extended information about spark plugs: 1. Spark plug size: The mainstream spark plugs in the Chinese market have a thread diameter of 14 mm. 2. Spark plug installation: (1) Choose the appropriate size: Always select spark plugs that are the correct size for your vehicle model. You can check the official website or, preferably, consult a 4S store. (2) Use the right tools: Specialized tools are necessary for removing and installing spark plugs. You can rent or borrow a set of tools and follow the torque specifications corresponding to the spark plug size for removal and installation. (3) Use the correct method: Avoid using excessive force. Prevent the spark plug from stripping its threads or even falling into the cylinder, which could cause engine damage or lead to ignition failure due to air leaks.

What Does a Car's Automatic Following System Rely On?

The automatic following system of a car mainly relies on the ACC control unit, which can coordinate with the anti-lock braking system and the engine control system to appropriately brake the wheels, ensuring the vehicle maintains a safe distance from the one ahead. Introduction to Adaptive Cruise Control System: The adaptive cruise control system is an advanced system built upon the traditional cruise control system that maintains a set speed. It adds the function of keeping a reasonable distance from the vehicle ahead. How the Adaptive Cruise System Works: Based on information detected by the inter-vehicle distance sensor, as well as the vehicle speed sensor and yaw rate sensor that determine the vehicle's driving route, the system judges whether there is a vehicle ahead in the same lane. The inter-vehicle distance sensor uses microwave radar or distance radar.

Is it necessary to install a reversing radar?

If the vehicle itself does not have the function of a reversing camera, it is highly recommended to install a reversing radar for driving safety. However, if there is already a reversing camera, the installation of a reversing radar becomes optional, and the decision should be based on personal driving habits. Introduction to Reversing Radar: A reversing radar is a safety assist device for parking or reversing a car. It informs the driver about surrounding obstacles through sound or more intuitive displays, eliminating the hassle of checking around when parking, reversing, or starting the vehicle. It also helps the driver overcome blind spots and unclear vision. How Reversing Radar Works: When reversing, the reversing radar uses ultrasonic principles. The sensor installed on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle and the obstacle, and then alerts the driver, making parking or reversing easier and safer.

What is Vehicle Classification?

According to the relevant provisions of China's national standards, vehicle classifications include trucks, off-road vehicles, dump trucks, tractor vehicles, special-purpose vehicles, buses, and passenger cars. Vehicle type refers to a form of vehicle distinguished by its general characteristics, intended use, and functionality. Below are the descriptions of each vehicle category: Truck: Also known as a freight vehicle, heavy-duty vehicle, or lorry. It is primarily used to transport various goods or tow full trailers. Trucks can be categorized into micro, light, medium, and heavy-duty based on their load capacity (1.8 tons, 6 tons, 14 tons). Off-road vehicle: Mainly used for transporting personnel and goods or towing equipment off-road, typically featuring all-wheel drive. They can be classified by drive type into 4×4, 6×6, and 8×8 configurations. Dump truck: Refers to a freight vehicle with a cargo compartment that can automatically tip over. There are two types: those that tip backward and those that can tip in three directions (left, right, and backward). Tractor vehicle: Specifically or primarily designed for towing. It can be divided into full-trailer tractors and semi-trailer tractors. Special-purpose vehicle: Equipped with specialized equipment and designed for specific transportation tasks or operations. Bus: A vehicle designed to carry nine or more passengers, featuring a rectangular compartment mainly for transporting people and their luggage. Buses are categorized into micro, light, medium, large, and extra-large based on their length (3.5 meters, 7 meters, 10 meters, 12 meters). Passenger car: A small passenger vehicle accommodating 2 to 8 people. It can be classified into micro, standard, intermediate, upper-intermediate, and luxury cars based on engine displacement (1 liter, 1.6 liters, 2.5 liters, 4 liters).

How Many Days Does It Take to Detect a Covered License Plate?

Generally, it takes 3-7 days. Covering a license plate is a serious traffic violation.

Unless the covering process is captured on camera. License Plate Overview: A license plate, commonly known as a vehicle plate, refers to the plates affixed to the front and rear of a vehicle. They are usually made of aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, or other relevant information. Traffic Violation Overview: A traffic violation (formerly called a traffic offense, now referred to as a traffic infraction) generally refers to actions by motor vehicle drivers, non-motor vehicle riders, or pedestrians that violate road traffic safety laws, traffic management regulations, or affect road conditions. Additionally, a violation can also refer to handling matters contrary to standard procedures.

What is the Fire Compartment Area for an Automobile Garage?

For open-type, staggered-floor, and sloping-floor automobile garages, the interconnected upper and lower floor areas should be calculated cumulatively. The maximum allowable floor area for each fire compartment should not exceed 2.0 times the values listed in the table above. For mechanical parking garages with driveways and personnel occupancy, the maximum allowable fire compartment area should be reduced by 35% compared to the values in the table above. Fire Safety in Automobile Garages: Automobiles are the most widely used means of transportation today, handling heavy passenger and freight transport tasks. Automobile garages (or parking lots) are facilities used for parking or vehicle maintenance. In the event of a fire in an automobile or garage, extinguishing the fire is challenging, and the consequences can be severe. Therefore, it is essential to strengthen safety management for both automobiles and garages. Introduction to Automobile Garages: Commonly referred to as garages, these are buildings designed for parking automobiles powered by internal combustion engines and without rails, such as buses, trucks, and engineering vehicles.

What is the Function of a Clutch?

The function of a clutch is to ensure stable vehicle starting and smooth gear shifting. During the driving process, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transmitting the power from the engine to the transmission. Clutch Introduction: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. Clutch Precautions: The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris.
