Do Vehicle Inspection Stations Work on Holidays?

Vehicle inspection stations operate during holidays. Vehicle Annual Inspection: The annual inspection period is calculated from the date of vehicle registration, and the next inspection date will be clearly noted on the supplementary page of the driving license. Inspection applications can be submitted up to 3 months before the annual inspection date. Additionally, the 6-year exemption for new vehicles does not mean exemption from annual inspection procedures. It refers to waiving the step of bringing the vehicle to the inspection station for testing, but this testing procedure is only one part of the annual inspection. Owners still need to apply for the inspection mark every two years. Pre-inspection Notes: All vehicle violation records must be cleared before inspection. Vehicle modifications are not allowed. A copy of the insurance policy must be submitted during inspection, and this copy will be retained by the inspection agency. Required documents include: driving license, compulsory traffic accident liability insurance policy (copy), inspector's ID card, triangular warning sign, and fire extinguisher. Notably, if the owner needs to delegate the annual inspection to someone else due to busy schedule or other reasons, the owner's ID card is not required; the agent can provide their own ID card instead.

What is the Principle of Kinetic Energy Recovery?

The principle of kinetic energy recovery is to convert the electric motor into a generator, recovering the energy generated during braking and storing it in a high-voltage battery. Kinetic Energy Recovery System: During normal driving, it is inevitable for a car to need to decelerate. At this time, the engine's power output is paused, and an additional resistance load is added to consume the inertia of the car's continued forward motion. This resistance load device is the brake. During braking, the car's forward inertia works on the vehicle's brake, converting it into heat energy of the friction pads, which is irreversibly lost. The current basic solution principle is to store the car's forward inertia using a device or equipment and reuse it when needed. This device is the kinetic energy recovery system. Principle of Kinetic Energy Recovery System: The kinetic energy recovery system is a technology used by FIA in F1 racing cars, abbreviated as KERS in English. Its principle is to recover the vehicle's braking energy through certain technical means and release it as auxiliary braking force during the car's acceleration process. The working principle of a general kinetic energy recovery system is as follows: through the ECU integrating battery control components, it controls the engine and the kinetic energy recovery system. The engine and motor installed on the car act as generators when collecting energy and switch to motor mode when releasing energy. The lithium battery on the car is used to store the electrical energy collected by the engine, and the multifunction steering wheel has an acceleration button to control the duration of energy release.

What is the function of the small wheels at the front of a wiggle car?

The small wheels at the front of a wiggle car are designed to prevent collisions when the ground is uneven. Precautions for riding a wiggle car: Ride on flat surfaces; control the speed of the wiggle car; regularly check if the wheels, frame, etc., of the wiggle car are loose; minimize the use of legs to propel the wiggle car; avoid letting children ride the wiggle car in dangerous areas like roadsides. Concept of a wiggle car: A wiggle car, also known as a fitness and entertainment vehicle, does not require charging, fuel, winding, or pedaling. It moves simply by shaking the steering wheel left and right. Its driving principle is based on centrifugal force and curved force laws, enabling free movement without the need for electricity, fuel, or spring drives. It combines environmental friendliness, entertainment, and fitness into one.

What is the Micro Public Transit Vehicle?

Micro Public Transit is a pure electric vehicle. Purpose of Implementation: Primarily aimed at promoting new energy sources, given the severe environmental pollution. 'Micro Public Transit' achieves zero emissions and zero pollution, and has received government support. The 'Micro Public Transit' only requires a standard 220V socket for charging, which can be done anywhere. A full charge takes 6 to 8 hours, with a top speed of 80 km/h, and a single charge allows for a range of over 100 kilometers. Development Status: 'Micro Public Transit' is the first pure electric vehicle time-sharing rental service in China, with experts calling it a revolution in urban public transportation. The service is currently operational in Hangzhou, with 5,000 'Micro Public Transit' vehicles serving citizens, receiving positive market feedback and recognition and support from government departments.

What is the difference between ladder frame and unibody construction?

The body strength and rigidity differ between vehicles with ladder frames and those without. Ladder frame concept: The fundamental structure of a vehicle, typically composed of two longitudinal beams and several cross members, supported on wheels via suspension systems, front axle, and rear axle. It possesses sufficient strength and rigidity to withstand vehicle loads and impacts transmitted from the wheels. Differences: Passenger cars use unibody construction for comfort, while commercial vehicles employ ladder frames for economic benefits and compressive resistance. Advantages of ladder frames: superior body strength; high rigidity; enhanced vehicle safety; excellent impact and bump resistance. However, the body tends to be bulky, heavy, and tall. Advantages of unibody construction: relatively lighter weight; lower center of gravity; easier assembly. But it has weaker torsional resistance and load-bearing capacity, with smaller mass and lower height.

How to Reverse an Automatic Car on a Slope?

When reversing an automatic car on a slope, it is important to keep the vehicle moving at a low speed. Steps for reversing uphill: Press the brake pedal to bring the car to a complete stop. Hold the lock button on the gear lever and shift to the R (Reverse) position. Check the side mirrors and rearview camera to ensure there are no obstacles behind the car. Additionally, honk the horn twice to alert nearby pedestrians and vehicles. Gradually release the brake pedal (or lightly press the accelerator) to allow the car to move at a low speed. Important Notes: It is always best to start the engine before moving any car. Only when the engine is running will the power steering and brakes function properly. Driving without starting the engine is extremely dangerous. When reversing on a slight slope, it is advisable to start the engine first. If you want the car to coast down, shift to the N (Neutral) position, release the handbrake and foot brake, and the car will roll down. At this point, both the steering and foot brake will be operational, allowing the driver to stop or turn the car as needed.
