What are the functions and roles of spark plugs?

How spark plugs work: The ground electrode of the spark plug is connected to the metal shell, which is threaded into the engine block through the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the center electrode, it ionizes the medium between the center electrode and the ground electrode to generate a spark, thereby igniting the air-fuel mixture in the cylinder. Spark plug replacement intervals: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. The following standards can be used as a reference for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

How to Check the Production Date of Glass?

The production date of automotive glass is usually marked in the lower right corner of the window or below the logo. Here is a detailed introduction to the coding of automotive glass: 1. Date Reading Method: The numbers represent the year, small dots represent the quarter (there are 4 quarters in a year, with a maximum of 4 small dots), and large dots represent the months within the quarter (a quarter consists of 3 months, with a maximum of 3 large dots). 2. 3C Certification: The authenticity of the glass determines its shatter resistance and the extent of injury it may cause upon breaking. A qualified automotive glass product must have 3C certification, and this 3C certification mark should be clear and extremely difficult to scrape off with a fingernail or blade.

What is chaoyang tire?

chaoyang is Chaoyang tire. The following is the specific introduction of Chaoyang tire: 1. Product field: Chaoyang tire is a brand under Zhongce Rubber Group Co., Ltd. Chaoyang tire focuses on the production and manufacturing of tires and rubber products, and its products have covered passenger car tires, commercial vehicle tires, industrial engineering tires, agricultural tires and two-wheel tires. 2. Tire composition: The tire is generally composed of three parts: the outer tire, the inner tube and the cushion belt. The inner layer of the tire has a rubber layer with good air tightness, gradually making the tire develop in the direction of lightweight. The outer tire is mainly composed of the tire body buffer, the tread sidewall and the bead. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces and high and low temperature effects during driving, so they must have relatively high load-bearing performance, traction performance and cushioning performance.

What is the Difference Between Tiptronic and Automatic Transmission?

Here are the specific differences between automatic transmission and tiptronic transmission: 1. In terms of shifting method: Tiptronic combines manual shifting and automatic shifting, allowing free adjustment of gears and RPM. Automatic transmission vehicles use an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's RPM and load, replacing the driver's subjective judgment of timing and shifting operations. 2. In terms of characteristics: Tiptronic requires higher maintenance costs and more stringent usage requirements. In automatic transmission vehicles, when the gear lever is placed in the drive position and the brake pedal is released, as the throttle is applied and the engine RPM increases, the transmitted torque increases, pushing the vehicle forward. 3. In terms of driving experience: Manual transmission provides a sporty driving experience due to the ability to adjust gears and RPM, offering more driving pleasure. The advantages of automatic transmission become more apparent in traffic jams.

Does Adding Water to Antifreeze Have Any Impact?

Adding water to antifreeze does have an impact on the vehicle, as it lowers the antifreeze's freezing point and can cause boiling. Additionally, it reduces the antifreeze's antifreeze properties, and in severe cases, the engine may be at risk of cracking due to freezing. Methods to Determine if Antifreeze is Low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add antifreeze. Inspect the water level markings on the antifreeze bottle. Normal antifreeze levels should be between the maximum and minimum marks. To determine if antifreeze is low, check the markings—if the level is below the minimum, it indicates a deficiency. Method for Replacing Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with particular attention to the five-way hose. The five-way hose gets its name from having five connection points to various parts of the vehicle. Antifreeze flows through this hose and is distributed to different parts of the car to perform its function. If there are signs of antifreeze leakage in this area, replace the hose or resecure the connections as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir and continue filling until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Continue adding clean water until the outflow is clear. Note: Remember to disconnect the heater hose and drain any remaining water from the heater core.

What is the function of ESP in a car?

ESP stands for Electronic Stability Program. Here is a detailed introduction to the ESP system: 1. Function: ESP is the Electronic Stability Program, which analyzes vehicle driving state information from various sensors and issues commands to ABS, EBD, etc., helping the vehicle maintain dynamic balance. ESP can keep the vehicle stable under various conditions, with particularly noticeable effects in cases of oversteering or understeering. 2. Oversteering situation: When the ESP system sensors detect and transmit signals to the ESP control unit, it will intervene by braking the outer front wheel during steering. Through single-wheel braking, this allows the vehicle to remain stable without driver intervention. 3. Understeering situation: After the ESP control unit receives the sensor signals, it brakes the inner rear wheel during a turn. Through such braking corrections, the vehicle's stability is also ensured.
