The function of the S gear in an automatic transmission car is: 1. In this mode, the vehicle's power performance is stronger, commonly used for overtaking, uphill driving, long downhill driving, traffic jams, and clearing carbon deposits; 2. The transmission can shift freely. The S gear is the car's sport mode, where the transmission can shift freely in sport mode, keeping the engine at high RPM for a longer time, allowing the car to drive at low gear and high RPM for an extended period, thereby obtaining greater torque output and acceleration. Situations where the S gear is not suitable include: 1. High-speed driving is not suitable for the S gear, as the S gear is set to downshift for speed increase, which can cause the vehicle speed and RPM to mismatch, increase noise, and raise fuel consumption; 2. Coasting is not suitable for the S gear, as it can cause significant wear to the transmission in a short time.

How Long Can Automotive Paint Last Without Peeling?

As long as the paint job is done through proper channels, such as at a 4S shop, and genuine paint is used, the quality is generally guaranteed without major issues. Therefore, such paint jobs can typically last for 4 to 5 years without problems. Relevant information about car waxing is as follows: Introduction: Car waxing, as a traditional aspect of car detailing, primarily serves to waterproof and protect against acid rain. The protective layer of wax reduces the amount of water droplets adhering to the car body. Waxing Frequency: Theoretically, the interval for car waxing depends on how long the wax layer remains effective on the paint surface, which in turn is determined by the quality of the wax used.

Does Rain Affect a Car After Polishing?

Rain can affect a car after polishing, as rainwater contains acidic substances that may damage the car's paint. Introduction: Car polishing is a step in the car detailing process, performed before waxing, sealing, or coating to prepare the car's surface. Polishing, especially fine polishing, is essential for achieving a mirror-like finish required for sealing or coating. This step is mandatory for effective sealing, as untreated or uneven paint surfaces will not hold the sealant for long, failing to provide lasting protection. Market: The demand for car polishing is significant, yet the supply is somewhat limited. There are few companies with core intellectual property rights and high-quality products, resulting in a lack of strong brand recognition across the industry.

Will a Car's Generator Be Damaged When Driving Through Water?

Water entering a car's generator will not cause immediate damage, but it can affect the engine's lifespan. It is recommended that car owners take protective measures. The generator is an electrical component containing stator windings and rotor coils. Related information about generators: Function: The car generator serves as the primary power source, supplying electricity to all electrical devices (except the starter) while the engine is running normally and simultaneously charging the battery. Composition: Due to the superiority of AC generators in many aspects, DC generators have been phased out. AC generators generally consist of four parts: the rotor, stator, rectifier, and end cover.

What Causes the Buzzing Sound in a Car Engine?

The buzzing sound may be caused by worn or loose wheel bearings or uneven tire wear. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. External Combustion Engine: An external combustion engine refers to an engine where fuel is burned outside the engine. Internal Combustion Engine: An internal combustion engine, specifically a reciprocating piston engine, differs primarily from external combustion engines in that the fuel is burned inside it. There are many types of internal combustion engines, with common examples being gasoline and diesel engines.

What problems will occur if the car relay is broken?

Symptoms of a damaged car relay include the starter not turning, the starter being weak, and the starter spinning freely. Function: The basic function of a car relay is to use a small current to control the operation of a large current, acting as an "automatic switch." It plays roles in automatic adjustment, safety protection, circuit conversion, and switching in the circuit. Selection based on usage environment: Usage environmental conditions mainly include temperature (maximum and minimum), humidity (generally referring to the maximum relative humidity at 40 degrees Celsius), low air pressure (can be ignored if the usage altitude is below 1000 meters), vibration, and impact. Additionally, there are requirements for packaging methods, installation methods, dimensions, and insulation. Due to differences in materials and structures, relays can withstand varying environmental mechanical conditions. Using a relay beyond the environmental mechanical conditions specified in the product standards may damage it. Therefore, relays can be selected based on the environmental mechanical conditions of the entire machine or higher conditions.

Where is the Reiz engine number located?

The Reiz engine number is located on the cylinder block, typically consisting of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle's driving license prints the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, with each engine using only one engine number, and each engine's number is unique.
