The new regulations are as follows: According to the latest regulations mentioned in the document, it is stipulated that reflective markings should be inspected on all trucks (excluding multi-purpose trucks and coach vehicles modified based on multi-purpose trucks), special operation vehicles modified from truck chassis, and trailers (excluding residential trailers). More relevant information is as follows: Inspection: For trucks (excluding multi-purpose trucks and truck-type coach vehicles) and special operation vehicles (excluding fire trucks), it is required to inspect whether the total mass (or maximum allowable towing mass), height of sideboards, tank volume, and the types or names of allowed cargo are marked.

Does a Fixed Gear Bike Have Brakes?

Fixed gear bikes have brakes. The braking methods are as follows: Skid Stop: The skid stop is actually a very simple maneuver. Maintain a riding speed of about 10 to 15, then when the rear foot reaches the highest point, place the front foot on the handlebar stem and straddle it. Then, use the rear foot to drive the crank for one full rotation. When the chainring reaches around the 7 o'clock position, apply force with the rear foot and push down to complete the skid stop. Track Stand: Shift your weight backward, extend both arms straight, and grip the saddle with your inner thighs. Position your feet symmetrically along a horizontal line (to facilitate adjusting front and rear positions). Determine which foot is naturally in front and turn the handlebars 45 degrees in that direction, then hold steady. If you feel like you're about to fall, you can slightly stand up to stabilize, concentrating your weight on both feet. Backpedaling: Here, it's worth mentioning that backpedaling isn't overly complicated, but it's not simple either. At the very least, to learn backpedaling, you must be able to perform a track stand for over 10 to 20 minutes (practicing stability, concentrating your weight, and learning how to apply force). The relationship between backpedaling and the track stand is like that of mother and child. Stand firmly in place, adjust your position slightly, with the rear foot slightly higher, then apply force to pedal backward. The next step is to sit on the saddle to find your balance. (During this process, you must practice keeping your weight pressed backward on the saddle while riding, with both arms extended straight, to maintain control of the entire situation.)

Why does an automatic transmission car suddenly shift gears while driving?

Automatic transmission cars suddenly shift gears while driving because the driver did not fully engage the gear when shifting. Solution: Simply shift the gear again. Introduction to automatic transmission gears: The gears on an automatic transmission car, from top to bottom, are P, R, N, D, S, and L. Cars that use automatic transmissions to adjust speed typically rely on the transmission's control system to automatically select the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and shifting operations. Precautions: Driving an automatic transmission car using only the parking gear (P), reverse gear (R), neutral gear (N), and drive gear (D) can fully meet the needs of general driving. However, in some special driving environments, other functional gears may be required.

How Many Types of Electronic Fuel Injection Systems Are There?

Automotive electronic fuel injection systems are divided into gasoline and diesel electronic fuel injection systems. Gasoline electronic fuel injection technology has a high penetration rate, and most major automobile manufacturers have mastered this technology. However, diesel electronic fuel injection technology is monopolized by a few companies such as Delphi (USA), Bosch (Germany), and Denso (Japan). Naturally, diesel electronic fuel injection systems for vehicles in China are also dominated by foreign brands. More relevant information is as follows: In terms of R&D: Especially in the field of diesel electronic fuel injection systems, there is a lack of participation from large companies, while small enterprises struggle with limited resources. Most efforts remain at the research and experimental stage, making it very difficult to achieve breakthroughs in a short time. In terms of industrialization: Even if technical challenges are resolved, there is still a long way to go before achieving industrialization. The establishment of production lines and the construction of marketing systems all require time, with progressive difficulties piling up layer by layer.

What are some names for car detailing?

Car detailing refers to the maintenance and care of various parts of a vehicle. Expanded information about car detailing: Services included in car detailing: Nowadays, car detailing is not just about routine care like car washing, waxing, stain removal, deodorizing, vacuuming, and interior cleaning. It also includes using professional detailing products and high-tech equipment for services such as car washing, paint surface detailing, interior care, and refurbishment of other vehicle components. Special techniques and methods are employed for paint surface enhancement, waxing, polishing, coating, crystal coating, scratch treatment (both deep and shallow), full-vehicle paint detailing, undercoating, and engine surface refurbishment—a comprehensive range of vehicle maintenance technologies. Differences in materials between car detailing and traditional car washing: Traditional car washing operations often lack proper cleaning equipment and tend to skimp on materials, such as using laundry detergent as car wash soap, with water sources that may not meet standards. In contrast, professional car detailing utilizes various specialized equipment and materials, all of which are safe, environmentally friendly, and pose no harm to human health or the environment. Only by using dedicated care products tailored to different vehicle body materials can a comprehensive detailing service truly achieve its purpose of vehicle maintenance and care.

Why Was There a Severe Shortage of Automotive Chips in 2021?

Because the current demand for chips in automobile manufacturing is significantly higher than before. In the past, automotive chips were mainly used to control electronic devices in the car and the engine. However, modern vehicles now include various assisted driving functions, which has considerably increased the demand for chips. More related information is as follows: Introduction to Automotive Chips: Automotive chips primarily refer to controller and processor chips. The normal operation of a vehicle relies on the processing of data and information. Note: Every function in a car involves chips. With the increasing production of automobiles, the shortage of chips has become frequent, as each controller requires chips.
