How can beginners judge the distance from the front of the car?

When you can see the upper edge of the rear bumper of the car in front, the distance is approximately 1 meter; when you can see the lower edge of the rear bumper, the distance is about 2 meters; and when you can see the bottom of the rear tires, the distance is around 3 meters. Here are some methods to judge the distance from the front of the car: 1. Imagine a person about 1.7 to 1.8 meters tall, with the top of the feet about 10 cm high, the knees about 45 cm high, and the bottom of the hips about 70 cm high. 2. When you see the front of the car moving upward from the ground to the person's feet or heels and stopping there, the distance between the front of the car and the person is about 3 meters. 3. When the front of the car rises to the height of the person's knees (i.e., you can see the knees), the distance is approximately 2 meters. 4. When the front or sides of the car rise to the bottom of the person's hips, the distance between the front of the car and the person is about 0.3 meters.

What are the age requirements for automatic transmission vehicles designed for people with disabilities?

The age requirement for automatic transmission vehicles designed for people with disabilities is between 18 and 70 years old. Specific requirements for obtaining a driver's license: For people with disabilities taking the driver's license test, the vehicle must be a small automatic transmission car, with the permitted driving model code C5. For the driver's license medical examination, individuals with left lower limb, right lower limb, or both lower limb disabilities are allowed to learn to drive. Among them, if only the left lower limb has motor dysfunction, they can learn to drive a C2 automatic transmission vehicle. For upper limb disabilities, the eligibility to learn to drive is determined based on the medical examination results from designated hospitals, such as missing certain fingers. Registration and training examination process: You need to find a driving school qualified to provide C5 driver's license training. The driving school will guide you to a designated hospital for a medical examination. If you pass the examination, you can successfully register. Study for the theoretical part of Subject 1 and take the exam. Participate in the practical training and exams for Subject 2 and Subject 3. You can schedule the Subject 2 exam 15 days after passing Subject 1 and the Subject 3 exam 20 days after passing Subject 1. After passing both Subject 2 and Subject 3, you can proceed to the theoretical training for Subject 4 and schedule the Subject 4 exam.

What is the difference between 1.8L and 1.8T?

1.8L and 1.8T have the following differences: 1. The 1.8T engine is a turbocharged engine equipped with a turbocharger, while the 1.8L engine is a naturally aspirated engine, which is a conventional engine. 2. After the turbocharger of the 1.8T engine engages, its maximum power output is significantly higher than that of the 1.8L engine (typically 1.5 times that of a naturally aspirated engine). 3. In terms of long-term maintenance costs, the 1.8L engine is less expensive and generally more reliable in terms of quality. The maintenance costs for 1.8T models are considerably higher, including expenses such as regular servicing, which usually requires 95-octane gasoline and full synthetic oil. Additionally, the turbocharger needs replacement after reaching a certain mileage. Below are some relevant details: 1. Turbocharged (and supercharged) engines are denoted by "T," while standard naturally aspirated engines are denoted by "L." The preceding number represents the engine displacement. Turbocharging is a technology that utilizes exhaust gases from internal combustion engine operation to drive an air compressor. 2. The primary function of turbocharging is to increase the engine's air intake volume, thereby enhancing its power and torque output, making the vehicle more powerful.

Does opening windows while sleeping in the car with AC on have any impact?

Opening windows while sleeping in the car with AC on does not have any impact, and it is also recommended to open windows for ventilation when sleeping in the car with AC on. When the car engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. While the car is moving, the air creates convection through the AC system, keeping the carbon monoxide concentration inside the car very low, so occupants won't feel anything. However, when the car is stationary with the AC still running and all doors and windows closed, the air inside the car cannot circulate. The carbon monoxide emitted by the engine can leak into the car and gradually accumulate, increasing its concentration, which can eventually lead to poisoning or even death of the occupants. Therefore, if you choose to rest in the car for an extended period, you should open both side windows slightly to allow ventilation, ensuring that carbon monoxide does not accumulate inside the car and maintaining a certain oxygen concentration. Additionally, avoid sleeping too deeply while resting in the car; it's best to set an alarm to wake up periodically. More importantly, do not use the AC in recirculation mode; allow the air inside the car to circulate with the outside air for safety. If the outdoor wind is strong, positioning the car with the front facing the wind can help direct exhaust gases away from the car, reducing the chance of exhaust entering the car and lowering the risk.

What Causes Low-Speed Jerking?

Transmission jerking is the impact sensation caused by the inertia of moving parts inside the engine. The following are the reasons for jerking: 1. Engine jerking: During the process where engine speed is either raised or lowered, if not handled properly, sudden changes in engine speed during gear shifts can cause the inertia of the engine's internal moving parts to react against the vehicle body. 2. Low-speed jerking: When driving at low speeds, frequent gear shifts between first and second gears cause the clutch to repeatedly disengage and engage, preventing smooth power transmission in a short time, resulting in common low-speed jerking. Jerking sensations may occur during startup and low-speed driving.

What does ACM mean in new energy vehicles?

ACM in new energy vehicles stands for Auxiliary-Control-Module in English, which translates to auxiliary control module in Chinese. Introduction to ACM: The ACM (Active Control Mount) system needs to be connected to the engine's intake manifold through an electromagnetic control valve (ECM), which is controlled by the electromagnetic control valve. Introduction to new energy vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and drive systems, resulting in vehicles with advanced technical principles, new technologies, and new structures.
