How long can the annual review of a B2 driver's license be delayed?

B2 driver's license annual review can be supplemented within three years after its expiration. If the review is not conducted for more than three years, a notice will be issued to downgrade the license within 30 days. If no action is taken, the driver's license will be declared invalid. However, driving motor vehicles is not allowed before the review. Therefore, drivers holding a B2 license should complete the annual review as early as possible. Notes related to B2 review: Drivers holding a B2 large truck driver's license should report to the traffic management department of the public security authority for review within 30 days after the end of each scoring cycle. However, if there is no record of demerit points within a scoring cycle, the review for that cycle is exempted. Motor vehicle drivers aged 70 or above should undergo an annual physical examination and submit a health certificate issued by a county-level or military regimental-level medical institution within 30 days after the end of the scoring cycle. Within 90 days before the expiration of the motor vehicle driver's license, an application for renewal should be submitted. When renewing the motor vehicle driver's license, the driver must undergo a review by the traffic management department of the public security authority. If the household registration of a motor vehicle driver is transferred out of the jurisdiction of the original vehicle management office, an application for renewal should be submitted to the vehicle management office of the new location, and a review is also required at this time.

What is the function of a grating?

Grating is the most important auxiliary equipment in sewage pumping stations. Generally composed of a set of parallel bars, it is installed at an angle of 60°~80° at the inlet of the pump station's collecting tank. A working platform should be set up behind the grating, usually 0.5m higher than the highest upstream water level. For manually cleaned gratings, the platform should be at least 1.2m long along the water flow direction, while for mechanically cleaned gratings, it should be at least 1.5m long, with a passage width of no less than 0.7m on both sides. 1. Grating specifications: (1) By shape: Gratings can be divided into flat and curved types. Flat gratings consist of bars and a frame. Curved gratings can be further divided into fixed curved gratings and rotating drum gratings. (2) By bar spacing: They can be classified into coarse (50~100mm), medium (10~40mm), and fine (1.5~10mm) gratings. Both flat and curved gratings can be made in these three types. 2. Related information: Since gratings are crucial for sewage treatment, newly designed sewage treatment plants usually employ coarse and medium gratings, or even coarse, medium, and fine gratings. Based on cleaning methods, gratings can be manual or mechanical. Manual cleaning is suitable for small sewage treatment plants when the residue volume exceeds 0.2m.

What is the deluxe edition version?

deluxe-edition means the luxury version in Chinese, which refers to a type of car with relatively high configuration and price. The luxury version of a car is the one with higher configuration among the same model, equipped with many more comfortable and high-performance devices. The luxury version usually refers to D-segment cars. D-segment cars generally have a wheelbase of more than 3000mm; the engine displacement is greater than 3.0 liters. Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Lexus LS, and Jaguar XJ are relatively common D-segment luxury cars. Here are the precautions for driving on highways: Drive in the designated lane: Highways have clearly marked lanes, including dedicated lanes for large vehicles, small vehicles, etc. Once you occupy a certain lane when overtaking, return to your corresponding lane in time after overtaking, and do not occupy other lanes for a long time. In addition, the emergency lane should not be occupied for a long time unless for special reasons. Maintain a safe speed and do not speed: The dangers of speeding are well known, whether on local roads or highways, it can cause irreversible consequences. Maintain longitudinal distance between vehicles: Generally, under dry road conditions and good braking, the distance between vehicles (m) should not be less than the numerical value of the speed (km/h). For example, when the speed is 80km/h, the distance should not be less than 80m; when the speed is 100km/h, the distance should not be less than 100m. Always pay attention to the distance signs on the roadside. In rainy, foggy, snowy, or wet road conditions, the distance between vehicles should be more than doubled. Pay attention to traffic signs: Always pay attention to the signs and markings on the roadside and overhead while driving, and drive appropriately to the right to avoid running over the right lane dividing line, so as to provide enough lateral distance for overtaking vehicles behind. Do not occupy the emergency lane at will in case of traffic accidents: Traffic accidents are inevitable on highways. If other vehicles cause traffic accidents that block the driving lane, do not occupy the emergency lane at will, which may prevent rescue vehicles from performing their duties. Avoid fatigue driving and take timely breaks: Fatigue driving is very dangerous on highways. Once a person is fatigued, their physical reaction ability decreases, making it difficult to respond correctly to emergencies.

How Long Does It Take to Remove a Three-Way Catalytic Converter?

Removing a three-way catalytic converter is a time-consuming and labor-intensive process. Here is some information about three-way catalytic converters: Introduction to Three-Way Catalytic Converters: A three-way catalytic converter is a device that converts harmful gases emitted from vehicle exhaust into harmless substances through oxidation and reduction reactions. Functions of Three-Way Catalytic Converters: (1) Improve fuel atomization, enhance combustion efficiency, reduce fuel consumption, and save 5-20% of fuel. (2) Enhance cold-start capability at low temperatures and reduce noise. (3) Boost engine performance, extend the lifespan of both the engine and the catalytic converter, and ensure proper vehicle maintenance.

What Causes Black Smoke and Insufficient Power in Diesel Vehicles?

Here are the possible reasons for black smoke and insufficient power in diesel vehicles: Reason 1: Check the intake system to ensure smooth air intake, proper turbocharger function, and correct valve clearance. Reason 2: Inspect the fuel lines for blockages or leaks in both high and low pressure circuits. Reason 3: Examine the fuel system for issues such as faulty fuel supply pumps, wear, or poor injector performance. Reason 4: Check for wear or damage to other engine components affecting power output. Insufficient piston ring tension can cause black smoke due to poor oil scraping, leaving residual oil on cylinder walls that mixes with combustion gases.

What is the principle of braking?

Car braking is fundamentally based on the driver pressing the brake pedal, which applies pressure to the brake fluid in the master cylinder. The fluid then transmits this pressure through the lines to the pistons in the brake calipers at each wheel. The pistons drive the brake calipers to clamp the brake discs, generating significant friction to slow down the vehicle. The following are the functions of the braking system: Service Brake: During driving, the service brake (foot brake) is commonly used to decelerate the car or bring it to a stop within the shortest distance possible; it also helps maintain a stable speed when driving downhill. Parking Brake: The parking brake not only keeps the car stationary but can also be used if the service brake fails. Once the car is parked, the parking brake (handbrake) should be applied to prevent the vehicle from rolling forward or backward.
