How many spark plugs are there?

There is one spark plug per cylinder, so a 3-cylinder car has 3 spark plugs, and a 4-cylinder car has 4 spark plugs. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage wires in the firing order, and then snap the cover back into place.

Why does the engine make a whining sound when accelerating with the AC on?

The detailed reasons for abnormal noises when accelerating with the AC on are as follows: 1. Caused by compressor damage: The electromagnetic clutch of the AC compressor may be slipping, or the internal bearings may be worn due to prolonged use. 2. Due to collisions during daily vehicle use: Or when replacing components such as the electric fan, radiator, or condenser, improper installation during repairs—such as mismatched part sizes, differences in rubber bushings, or improper alignment of the radiator and condenser frame—can cause body resonance when the electric fan operates with the AC on, leading to abnormal noises during acceleration. 3. Due to issues with the AC system pressure: If the radiator or condenser surface is excessively dirty, heat dissipation efficiency decreases. Poor heat dissipation after turning on the AC increases pressure in the pipes, causing the electric fan to operate at high speed and produce abnormal noises. Alternatively, overcharging the system with refrigerant can cause the system pressure to rise when accelerating with the AC on, leading to high-speed operation of the electric fan and resulting in abnormal noises.

What is diesel vehicle urea made of?

Automotive urea refers to an aqueous urea solution with a urea concentration of 32.5% and a solvent of ultra-pure water, made from specialized automotive urea raw materials and ultra-pure water. Automotive urea is an essential product for heavy-duty diesel vehicles to meet the China IV emission standards. Below is relevant information about automotive urea: 1. Introduction: For heavy-duty trucks, buses, and other diesel vehicles to meet the China IV emission standards, they must use an appropriate SCR system for exhaust treatment. This system requires urea solution to treat nitrogen oxides in the exhaust. Therefore, automotive urea solution has become an essential product for heavy-duty trucks and buses to achieve the China IV emission standards. 2. Usage instructions: Automotive urea must use Grade 1 ultra-pure water from the electronics industry. Since the SCR catalyst carrier is highly susceptible to metal ion poisoning, which would deactivate the catalyst, the urea solution must use Grade 1 ultra-pure water from the electronics industry. The urea solution begins to freeze at -11°C and completely solidifies at -20°C in practical use. Current technology involves adding modifiers to lower the solution's freezing point and external heating devices to prevent solidification.

What to Do If All 12 Points of a C1 Driver's License Are Deducted?

Drivers need to go to the traffic management department of the public security authority at the location of the violation to undergo a 7-day training program on road traffic safety laws and related knowledge, with 8 hours of instruction per day. After completing the training, they must pass the subject one exam to have their license points reset to zero. Below are the penalties for point deductions on a C1 driver's license: 1. If the license accumulates 11 points or fewer within a cycle, there is no significant impact on the driver. As long as the driver settles the violation records, the license points will reset to 12 in the next cycle. However, unpaid fines will carry over the points to the next cycle. 2. If the license accumulates 12 to 23 points within a cycle, the driver must attend the aforementioned 7-day training and pass the subject one exam to reset the points. 3. If the license accumulates 12 points or more twice within a cycle, the driver must not only complete the subject one training and exam but also retake the subject three training and exam. Only after passing both can the driver regain their license. 4. The probation period for a driver's license is one year. If a probationary driver accumulates 12 points, their license will be directly revoked.

How many turns is the steering wheel locked for C1?

C1 steering wheel with power steering generally turns a little more than one and a half turns, while those without power steering require about two and a half turns. The steering wheel is turned clockwise or counterclockwise until it can no longer rotate. Below are different steering techniques for various road conditions: 1. Continuous curves: First, pay attention to slowing down, and before entering the curve, if it's a right curve, slightly lean to the left, and vice versa. 2. Turning at intersections: Turn the steering wheel one full turn, but on narrow mountain roads, it must be turned fully. 3. U-turns are divided into two situations: One is at large multi-lane intersections, where you can use a "wide turn." Keep a slightly greater distance from the inner side of the vehicle to avoid scraping accidents. The other situation is at small single-lane intersections, where if you can't complete the turn in one go, consider making it in two passes. When making a U-turn, there's no need to lock the steering wheel completely; leave some room and adjust flexibly based on the actual situation.

What are the Three Guarantees for 4S Car Tires?

4S car tire three guarantees refer to repair, replacement, and refund, with the following regulations: 1. If quality issues are found before actual use after purchasing the tire, a new tire can be exchanged. For appearance quality issues, both parties can negotiate a solution; 2. If quality issues are discovered during use, the compensation standard is calculated based on the wear depth of the tread pattern; 3. Tires with quality defects that have undergone compensation procedures must have their trademark logos removed. Tires that are not eligible for compensation after evaluation must also have their trademark logos removed to distinguish them from genuine products and prevent duplicate claims.
