Fuel system cleaning is necessary. Carbon deposits and sediments can clog the injector needle valves and valve holes, affecting the performance of the precision components in the injection system, leading to poor fuel injection, inadequate atomization, and reduced power performance. Here is some relevant information about the fuel system: Fuel system maintenance methods: Regularly add high-quality fuel system cleaner (use once every 20,000 kilometers). Benefits of cleaning the fuel system: It can effectively remove gum, carbon deposits, and sediments from the combustion chamber, intake and exhaust valves, injectors, and fuel lines while driving, keeping all parts of the fuel system clean. Maintaining the cleanliness of the fuel system can also decompose moisture in the fuel and reduce harmful emissions.

Cleaning the fuel system is really necessary. I've worked in a repair shop for over ten years and encountered too many car failures caused by carbon deposits. Driving frequently in the city, especially short trips and frequent traffic jams, can easily lead to dirt buildup in the fuel injection system. Over time, issues like clogged fuel injectors, engine shaking, and soaring fuel consumption will arise. A thorough cleaning can make the car run smoother, restore the engine's original power level, and extend the lifespan of components. I recommend cleaning it every 20,000 to 30,000 kilometers. Don't wait until problems appear to address it, as replacing parts later can be costly. Handling it during routine maintenance is affordable, safe, and reassuring.

Is the Vehicle License Required to Be Kept in the Car?

Vehicle License must be kept in the car. Here are the relevant details: 1. Motor Vehicle License: It is the legal document that permits a motor vehicle to drive on roads within China. The license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page contains the endorsed core, while the back features a photo of the vehicle, all sealed in a plastic cover. The supplementary page also contains the endorsed core. 2. Article 17 stipulates: "A vehicle must pass the inspection by the vehicle management authority and obtain a license plate and a Vehicle License before it is allowed to drive." Therefore, possessing a Motor Vehicle License is one of the prerequisites for a vehicle to be driven on the road. Driving without carrying the Vehicle License is a violation, whether it is due to not having obtained the license or simply forgetting to bring it.

Will driving in S gear have any impact?

It will increase fuel consumption but has no impact on the vehicle. Here are the relevant details: 1. S Gear: This is the sport mode, which essentially increases the engine's power output by raising the shift RPM and increasing fuel injection. The sport mode in cars is generally controlled by the transmission computer, meaning the shift programming is different. 2. Benefits: The car's transmission will shift freely, but the shift timing is delayed, forcing the engine to maintain higher RPMs for a longer period. Although using S gear can reduce some safety hazards during overtaking and better utilize the engine's braking effect when going downhill, thereby improving safety.

What Causes Cracks in Tires of a New Car Less Than a Year Old?

Cracks appearing in the tires of a new car less than a year old may be related to the quality of the tires. Below is an introduction to tire-related information: 1. Functions of tires: Mainly include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load-bearing capacity, handling performance, average wear, and mileage. 2. Tire cross-sectional structure: Generally, it can be divided into four parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the rim to provide sealing. 3. Internal composition of tires: The inside of the tire is composed of multiple layers of different materials, including tread pattern, cover layer, steel belt layer, stress absorption rubber strip, carcass ply layer, and airtight layer.

How long does it take to check traffic violations on highways in another city?

It usually takes 3-5 days to check traffic violations on highways in another city. Here are the relevant details: 1. Violation: The captured footage needs to be confirmed before it can be uploaded to the traffic police internal network. The time required for confirmation and upload varies depending on the location, behavior, and penalty of the violation, typically taking 3-5 days. Not all violations can be confirmed and uploaded immediately. 2. Out-of-city violations: Car owners need to bring their ID card, driver's license, vehicle license, and violation notice to the traffic management department for processing. The deadline for processing violations is 15 days. After 15 days, a late fee of 3% per day will be added, with the maximum not exceeding the original fine amount.

What is the RPM for first gear clutch engagement?

First gear clutch engagement is at 1000 RPM. Below are the relevant details: 1. Engine RPM: When shifting gears and accelerating, you should not focus on the engine RPM. Instead, release the clutch slowly while gently applying throttle to start the vehicle, then fully release the clutch and apply appropriate throttle. Considering RPM can be misleading, especially on slopes where higher RPM may be required. Therefore, operation should not be based solely on engine RPM. 2. Clutch semi-engagement: This refers to the unstable connection state of the clutch, where the driver presses the clutch pedal to gradually reduce clutch pressure, resulting in a combination of rotation and slipping between the driving and driven plates. The main purpose of semi-engagement is to prevent stalling during operation. Most civilian engines maintain an idle speed between 600~1000 RPM, which corresponds to a fixed transmission speed, typically ranging between 0~10 km/H.

What lights to use when passing through a crosswalk at night?

At night, you should alternate between high and low beams at least twice when passing through a crosswalk. Here are the relevant details: 1. Article 59: When a motor vehicle passes through a sharp curve, slope, arch bridge, crosswalk, or an intersection without traffic signal control at night, it should alternate between high and low beams as a signal. When a motor vehicle approaches sections with limited visibility that affect safety, such as sharp curves or the top of a slope, or when overtaking or encountering an emergency, it should slow down and sound the horn as a signal. 2. Low visibility: In low-visibility conditions such as at night, the driver's visible range is much greater when using high beams compared to low beams, but high beams are not suitable for all scenarios.
