Subject 2 cannot be canceled on the platform. You can only call directly and ask the staff to cancel it. Here are specific tips for the driving test Subject 2: 1. Slow speed: Keeping the speed slow is the fundamental rule for practicing Subject 2. Ensure the car doesn't stop while keeping the speed as slow as possible. A slower speed allows sufficient time to adjust each operation. 2. Adjust the rearview mirrors: After getting in the car, always adjust the rearview mirrors properly, which is especially important for reversing into the garage and parallel parking. 3. Master the three-point alignment method: The three points are the driver's eyes, a reference point on the car, and a reference point on the ground. During Subject 2 operations, you must accurately identify and observe these points to ensure precise positioning. 4. Pay attention to the four corners of the car: The front corner is prone to sweeping the outer line when reversing into the garage, while the rear corner is prone to sweeping the side lines of the garage; the front corner is likely to cross the line during curve driving; the front corner is prone to crossing the line during a right-angle turn; the front corner is prone to sweeping the outer line or the left front corner of the garage during parallel parking, while the right rear corner is prone to sweeping the right garage line. Therefore, always be mindful of the four corners and the outer lines.

I remember being extremely nervous before my Subject 2 test and wanting to cancel the appointment last minute. I opened the 12123 App, logged into my account, and found the "Exam Appointment" section. After clicking in, I could see all my scheduled exams. I selected the Subject 2 entry and clicked "Cancel Appointment." The app then prompted me to choose a cancellation reason, such as a schedule conflict or feeling unwell, and after filling it out, I just submitted it. The app processes the request, and usually within a day or two, you'll receive a confirmation SMS for the cancellation. But don’t cancel too often—frequent cancellations can leave a bad record. I suggest evaluating your skills first, practicing reversing and parallel parking until you're confident before taking the test. This makes the roads safer. Back in my day, we didn’t have apps and had to queue for hours at the DMV. It’s much more convenient now, but don’t abuse the feature. Safe driving tests start with preparation, and every cancellation is a chance to reflect and learn.

Reasons Why an Excavator Has Power but Fails to Start

Possible causes include burnt or poor contact inside the battery relay. Also check the contact condition at the battery terminals by pouring hot water over them and starting the engine - poor contact will cause overheating until the water evaporates. Reasons for excavator failing to start: 1. Loose battery clamps causing starting difficulties. 2. Insufficient battery power or loose battery terminals leading to poor contact. 3. Faulty starter motor or generator failing to produce adequate power. 4. Using inappropriate fuel - high viscosity diesel in winter and low viscosity diesel in summer.

What is the method for adjusting valve clearance in a six-cylinder engine?

Place an appropriate feeler gauge between the rocker arm and the crosshead. Loosen the lock nut on the fuel injector rocker arm until the plunger contacts the injector cup, then tighten it by 15° to expel the oil in the cup. Back off the adjustment bolt by one turn, then use a screwdriver to tighten the adjustment bolt until there is no gap between the fuel injector plunger and the tappet. Follow the engine firing order (1-5-3-6-2-4).

Why are AT and CVT transmission efficiencies lower than dual-clutch?

AT and CVT transmissions have lower efficiency than dual-clutch transmissions because: AT transmissions are connected to the engine via a torque converter, which internally uses transmission fluid, making it a soft connection; CVT transmissions transmit power through friction between the steel belt and pulleys, and the steel belt can slip; dual-clutch transmissions are connected to the engine via clutch plates, which is a hard connection, resulting in higher transmission efficiency. Dual-clutch transmissions have gear sets inside, and this type of transmission does not rely on friction to transmit power, leading to lower power loss.

How Many Days Can a Car Battery Sit Without Being Used?

Under normal circumstances, the number of days a car battery can sit without being used depends on its capacity and level of degradation. Generally, a car battery can remain idle for up to two months without affecting its normal operation. When parking the car for an extended period, disconnecting the positive and negative terminals of the battery can prevent natural power drain. For cars in poorer condition, if the battery runs out of power within about a week, simply starting the car and driving normally for one to two hours can restore the battery to its normal charge. If the car is in such a severe condition that the engine cannot be started, a jump start may be required to activate the generator.

What is the function of the brake pedal?

Brake pedal is the pedal that limits power, namely the pedal of the foot brake (service brake), used for deceleration and stopping. It is one of the five major control components in automobile driving and is used very frequently. How the driver controls it directly affects the safety of automobile driving. More information about the brake pedal is as follows: Function: Braking to decelerate or stop. Working principle: A wheel or disc is fixed on the high-speed shaft of the machine, and a corresponding brake shoe, belt or disc is installed on the machine base to generate braking torque under external force. The brake pedal must be pressed with the tip or center of the foot, and the steering wheel should be firmly held when pressing the brake pedal; it is not allowed to press the brake pedal while pressing the accelerator pedal.

What Do Engine Power and Torque Mean?

Engine power is a physical quantity that describes how quickly work is done, meaning that for the same amount of work, the shorter the time taken, the greater the power. Engine torque refers to the specific rotational force output by the crankshaft in the crank-connecting rod mechanism. Under the same power conditions, the faster the speed, the smaller the torque, and the slower the speed, the greater the torque. The magnitude of torque also, to some extent, demonstrates the vehicle's load capacity. These two factors are crucial parameters in determining the quality of an engine. For example, a car with higher power will have better endurance, while a car with higher torque will exhibit stronger explosive force. Both are extremely important for an engine.
