What is the depreciation period for a van?

The depreciation period for a van is 10 years. Overview of depreciation periods: Tax laws stipulate the following minimum depreciation periods for fixed assets: 20 years for houses and buildings; 10 years for trains, ships, machinery, mechanical equipment, and other production equipment; 5 years for electronic equipment, transportation vehicles other than trains and ships, as well as tools, furniture, and other items related to production and operation. The residual value ratio is uniformly set at 5% of the original price. Depreciation positioning: Even for used vehicles, the depreciation period is calculated as 5 years from the date of purchase. There are several different methods for depreciating vehicles, which can be easily confused. These generally include the straight-line depreciation method (straight-line method), accelerated depreciation method (MACRS), and special depreciation method (special depreciation allowance method).

What is the function of a fuel pump?

The function of a fuel pump is to draw gasoline from the fuel tank and deliver it through the pipeline and fuel filter to the float chamber of the carburetor. Below are the specific details about the fuel pump: 1. Unaffected by air pressure and component wear: The operation of the fuel pump is driven by the eccentric wheel on the engine camshaft. In diesel engines, the camshaft is installed in the crankcase, while in gasoline engines, it is mounted on the cylinder head. The eccentric wheel drives the rocker arm, which pulls the diaphragm downward, compressing the spring. This creates a negative pressure in the space above the diaphragm, drawing fuel in through the inlet port. Since the outlet valve is closed, the fuel is stored in the volume above the diaphragm. The pump rotor comes into contact with gasoline, which does not cause wear and is only responsible for providing pressure. Fuel pressure regulation is handled by the pressure regulator and is independent of atmospheric pressure. 2. The fuel pump is controlled by the ECU: The operation of the fuel pump is primarily determined by the ignition switch and the ECU. As long as the engine is running, the fuel pump will operate. If the engine stops, the interrupted signal will prevent the transistor VT from conducting, causing relay L1 to stop working, and the fuel pump will also cease operation. Even if the engine is not started, turning the key switch to the 'on' position will activate the VT control circuit, typically causing the fuel pump to run for 3-5 seconds before shutting off, pre-pressurizing the pipeline.

What is the correct way to press the accelerator pedal?

Correct methods for pressing the accelerator pedal are as follows: 1. Locate the pedal position: Place the heel of your right foot on the floor of the driver's compartment as a pivot point. Gently press the ball of your foot on the accelerator pedal, using ankle joint flexion to depress or release it, as shown in the illustration. 2. Key techniques for accelerator pedal operation: Press lightly and release gradually, accelerate linearly, apply force gently, avoid sudden movements, use toe control, and prevent jerky motions. 3. Light press and gradual release: When starting the engine, don't depress the throttle pedal completely; it's better to keep it slightly above idle speed. 4. Linear acceleration: During startup, apply throttle slightly before the clutch engagement point, with moderate throttle opening being optimal. Coordinate clutch pedal release with throttle pedal pressing for swift action. 5. Gentle force application: While driving, adjust throttle opening according to road conditions and actual needs. Select appropriate gears to keep the engine running at medium speed most of the time for fuel efficiency. If the engine doesn't respond with increased RPM when the throttle is depressed 3/4 of the way, downshift before accelerating again. 6. Avoid abrupt movements: When climbing hills, don't floor the throttle pedal; in low gears, typically depress it halfway. 7. Toe control technique: Even when charging up hills, avoid fully depressing the throttle pedal. 8. No sudden jerks: Before stopping the vehicle or turning off the engine, first release the throttle pedal; never rev the engine abruptly with neutral throttle.

Do all urban road cameras measure speed?

Urban road cameras do measure speed. Mobile speed measurement: This type of speed measurement is random. Traffic police will set up a speed measuring device at a random point on the highway. This method is characterized by its single-point nature, unpredictability, and mobility, making it difficult to avoid through navigation. Section speed measurement: Section speed measurement is more complex in terms of equipment compared to single-point speed measurement. At the starting point of the section speed measurement, there is a set of speed measuring devices, and at the ending point, there is another set. By recording the time a vehicle enters the starting point and the time it leaves the ending point, and dividing the length of the measured section by the time taken, the average speed can be accurately calculated. Section speed measurement is considered more reasonable.

What is the Rearview Mirror Parking Assist Function?

The rearview mirror parking assist system intuitively informs the driver of the relative position between the vehicle and obstacles through images and sounds, eliminating the blind spots caused by rearview mirrors. This provides convenience for drivers during parking and reversing, while also enhancing safety. Operating Principle: The reversing camera system utilizes visual measurement-based rearview technology. It relies on a rear-mounted camera to display road conditions behind the vehicle on the central display screen. The driver can freely move a square representing the vehicle body on the touchscreen. When the position is appropriate, the square will change from red to green. At this point, simply engage reverse gear and control the vehicle speed to complete automatic parking. Structural Components: The reversing camera system consists of three main parts: the camera device, control unit, and display.

Which countries do not have Subject 2 in their driving tests?

There are many countries that do not have Subject 2 in their driving tests. Each country has different road designs and driving regulations, so not all countries use the Subject 1 and Subject 2 format for obtaining a driver's license. Reverse Parking: Considered the most challenging part of the Subject 2 test, the difficulty lies in mastering the timing of steering. Hill Start: Rolling back or stalling during hill starts is a common issue. If the car starts to roll back while releasing the brake, immediately press the brake and clutch firmly to stabilize the vehicle, then restart using the same method. 90-Degree Turn: There are many techniques for executing a 90-degree turn. The simplest one is to turn the steering wheel sharply when the hood covers the opposite yellow line.
