What is Continuously Variable Transmission?

Can license plates be transferred to others?

License plates cannot be transferred to others. The original license plate can only be transferred to the owner's new vehicle information. According to the motor vehicle registration regulations, when a motor vehicle undergoes a transfer registration, the license plate must be replaced. Only yellow license plates for commercial vehicles can be retained. Vehicle transfers require a license plate change, and the new owner can randomly select a number from the self-service selection machine. The old license plate must be surrendered. The old license plate number can be retained under the original owner's name for one year. If not used within this period, it will be recycled into the number resource pool. The vehicle management office may periodically release numbers when the available pool is insufficient. License plates, also known as vehicle registration plates, are plates mounted on the front and rear of a vehicle, typically made of aluminum, plastic, or stickers. They display the vehicle's registration number, registration region, or other basic information. License plates serve as unique identifiers for vehicles, allowing identification of the province, city, or county to which the vehicle belongs. The vehicle management office can trace the vehicle's owner through the license plate.

What Are the Types of Brakes?

Automobile brakes can be broadly categorized into two types based on their overall structure: disc brakes and drum brakes. Drum brakes can be further divided into internal expanding type and external contracting type, while disc brakes can be classified as full-disc type and caliper-disc type. Here is a detailed introduction: Disc Brakes: Disc brakes are the most common type of braking system. They utilize stationary brake pads that clamp onto a rotating brake disc attached to the wheel, creating friction to reduce the wheel's rotational speed. When the brake pedal is pressed, the piston in the master cylinder is pushed, generating pressure in the brake fluid lines. This pressure is transmitted through the brake fluid to the brake caliper. The piston in the brake caliper, under pressure, moves outward and pushes the brake pads to clamp the brake disc, causing friction between the pads and the disc to slow down the wheel. Drum Brakes: Drum brakes were the earliest braking systems used in vehicles. The brake drum is mounted on the wheel and rotates with it. Inside the drum, brake shoes are installed. When braking, the brake piston pushes the brake shoes outward to create friction with the brake drum, achieving the braking effect.

What Causes the Throttle of a Single-Cylinder Diesel Engine to Fluctuate?

It is mainly related to the fuel injection volume from the injector, the atomization effect of the fuel, and the mixing ratio with air. A common issue is severe contamination of the injector, which can clog it and lead to poor or uneven fuel injection. This results in inconsistent fuel delivery, causing the throttle to fluctuate. Additional Information: 1. Composition of a Diesel Engine: The internal system of a diesel engine consists of power transmission components, the engine block and main bearings, valves, the fuel system and governor, lubrication system, cooling system, and the starting system of the internal combustion engine. 2. Diesel Engine Fuel: The primary fuel for diesel engines is diesel. Typically, high-speed diesel engines use light diesel, while medium- and low-speed diesel engines may use either light or heavy diesel. Diesel engines employ an injection pump and injector to spray fuel into the cylinder under high pressure. The injected fuel atomizes and mixes with air for combustion. As a result, diesel engines can use heavier or lower-quality fuels with poor volatility, such as crude oil and residual oil.

How to Clock In for Subject 2?

When starting the in-car practice, insert the study time card into the clock-in device and press your fingerprint or begin facial recognition to start the clock-in. After the practice session ends, remove the card from the clock-in device to complete the study time clock-in. Below is relevant information about Subject 2: 1. Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license examination and refers to the field driving skills test. 2. Subject 2 Test Items for Small Vehicles (C1/C2): Includes five mandatory test items—reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns). Some regions may include a sixth item, highway card collection. 3. Subject 2 Test Items for Large Vehicles (A1/A2/A3/B1/B2): Includes pile test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, curve driving, right-angle turns, passing through a width-restricted gate, navigating continuous obstacles, driving on undulating roads, making U-turns on narrow roads, as well as simulated scenarios like highways, continuous sharp turns on mountain roads, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.

What is spow20 engine oil?

spow20 engine oil belongs to the highest grade of engine oil, and many Japanese cars use this type of oil. 'sp' represents the quality grade of the engine oil, with sg, sj, sl, sm, and sp being the grades for gasoline engine oils, where sp is the highest grade. 'ow20' indicates the SAE standard viscosity value of the oil. Additional information: Functions of engine oil: 1. Lubrication: There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearing bushes. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. 2. Auxiliary cooling: Engine oil has a relatively low specific heat value and is located inside the engine, so it does not inherently have a cooling effect. However, during engine operation, the oil can carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water (or antifreeze liquid) outside the engine casing. 3. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation. The flow of the lubricating oil washes away dirt generated on the working surfaces of the parts.

How to Deal with Excessive Car Voltage?

If the car voltage is too high, the solution is to repair the generator. Excessive voltage can damage the battery, easily harm the electronic control unit, and cause bulbs to burn out, leading to system-wide chaos. Therefore, the generator should be repaired as soon as possible. Additional Information: 1. Generator Working Principle: The generator operates based on electromagnetic induction, where the output voltage varies with the rate of change in the coil's magnetic field strength. In the generator, the rate of change in the magnetic field is regulated by the generator's rotation speed and the magnitude of the magnetic current, meaning the output voltage is determined by the generator's excitation current. 2. Generator Voltage: The generator voltage changes with the vehicle speed. When the speed is higher than the battery voltage, it can exceed the battery voltage by up to 30%. When the speed is lower than the battery voltage, it may drop to zero. 3. Voltage Regulator: Every car is equipped with a voltage regulator, which reduces the generator's high voltage to a suitable range for the car's use. When charging the battery, if the generator's voltage is too low, the regulator automatically draws current from the battery, ensuring the car always has a stable voltage supply.
