How much deviation in straight-line driving is considered unqualified?

In straight-line driving, the stability control of the driving direction is considered unqualified if the deviation angle of the vehicle's direction exceeds 10 degrees. Additional information is as follows: 1. Inverse ratio: During straight-line driving, the amount of steering wheel operation should be inversely proportional to the vehicle's speed. The faster the speed, the smaller the steering wheel operation should be, and the slower the steering wheel should be turned. 2. Driving: The vehicle should be driven in the center of the lane. On straight sections, try to find the feeling of driving on the right, left, or center to choose the appropriate driving position. 3. Principle: During straight-line driving, the steering wheel should be primarily controlled with the left hand, assisted by the right hand. Moreover, adhere to the principle of "timely correction, minimal turning and returning." If you feel the vehicle is deviating from the driving path, adjust the steering wheel as early as possible to correct it.

Why does the car's power drop significantly when the air conditioning is turned on?

When the car's air conditioning is turned on, the power drops significantly because the car's air conditioning is powered by the engine. The compressor's power comes from the car's engine, so running the air conditioning consumes some of the engine's power. Here is an introduction to the related content: 1. Power: The power of a typical car's compressor is around 2-5 kW, and the engine's maximum power is achieved when the engine reaches 5000 RPM. 2. Implication: This means that when the engine is running at low speeds, its power output is only around 20-30 kW, so the air conditioning can consume up to about 20% of the engine's power at this time.

How is a fuel injector composed?

Fuel injectors are divided into five components: the electromagnet assembly, armature assembly, valve assembly, injector body, and nozzle coupling. Electromagnet assembly: Consists of a coil, iron core, cavity, electrical connector, and retaining cap. When energized, it generates electromagnetic force to attract the armature plate upward, controlling the nozzle needle valve. The fuel supply section comprises the fuel tank, fuel pump, fuel filter, pressure regulator, and fuel injector. The fuel pump draws gasoline from the tank, filters impurities through the fuel filter, pressurizes the gasoline via the pressure regulator to ensure its pressure exceeds the intake manifold's negative pressure, and then delivers the gasoline to each cylinder's fuel injector through the fuel delivery lines.

What was the pass rate for Subject 2 in 2021?

In 2021, the one-time pass rate for Subject 2 was generally around 50%. Due to the high difficulty level of Subject 2, which requires both practical driving skills and psychological resilience, fewer candidates actually pass. Preparation tips for the Subject 2 test: 1. Pre-test preparation If you don't want to travel long distances to the vehicle management office for the test, consider staying at a hotel near the office the night before, preferably with a companion. Being well-rested and not having to rush to queue for a number is a good start to the test, helping you stay relaxed and composed. 2. Waiting before the test The vehicle management office usually opens at 7 AM, with tests starting at 8 AM. The assigned numbers are arranged in chronological order, and the position in the queue can give you a rough idea of your test time. If someone around you is extremely nervous and affects your mood, distance yourself immediately to avoid catching their anxiety.
