Does idling with AC on after starting the car have any impact?

Idling with the AC on after starting the car does have negative effects. Keeping the AC on while idling not only harms the vehicle, increases fuel consumption, and poses health risks, but also contributes to greater atmospheric pollution. Running the AC for an entire day can easily lead to carbon monoxide poisoning. Leaving the AC on while the car is stationary means the engine is only operating at idle speed, which results in incomplete combustion of gasoline. This incomplete combustion produces toxic substances such as carbon monoxide. If the car windows and doors remain tightly closed for an extended period under these conditions, exhaust fumes can enter the sealed cabin. When these fumes accumulate to a certain level, they can cause carbon monoxide poisoning. Precautions for using the car AC: After the car has been exposed to the sun outdoors, first turn on the external circulation to ventilate and dissipate heat. You can also open the windows and sunroof to speed up the cooling process. After 3-5 minutes, when the interior temperature has stabilized, close all windows, turn on the air conditioning, and switch the AC to internal circulation. In cold weather, wait a moment after getting in the car until the engine reaches normal operating temperature. Then, turning on the heater with internal circulation can quickly raise the temperature.

What does the R gear mean?

R gear means reverse gear, used for reversing; D gear means drive gear: the car must be shifted to D gear to move forward; P gear means parking gear, when the car is parked and not in use, the gear is in this position, at which time the wheels are mechanically locked to prevent the car from rolling. Additionally, there is the L gear, which means low gear. When going downhill or descending a long slope, shifting to this gear limits the car's gear to only the lowest gear (equivalent to first gear in a manual transmission car), allowing the car to use engine power for braking when going downhill, preventing the driver from having to press the brake for a long time, which could cause the brake pads to overheat and lead to danger.

How fast can 136 horsepower go?

136 horsepower for a non-sports car should be below 200 km/h. Here is relevant information: 1. Horsepower: Horsepower is a unit of measurement for power, with two calculation methods: metric and imperial. Currently, the metric horsepower unit is used. 136 horsepower represents the maximum power output of the engine, not a unit of speed. The unit of speed is kilometers per hour. Horsepower and power data refer to the same concept, both describing work done. The higher the power, the higher the engine speed, and the higher the maximum speed of the car. 2. Power: Power refers to the amount of work done by an object per unit of time, meaning power is a physical quantity that describes how quickly work is done. For a given amount of work, the shorter the time, the greater the power value. The formula for power is power = work / time. Power is a physical quantity that indicates the speed of work done. The work done per unit of time is called power, denoted by P. Therefore, power equals the scalar product of force and the speed of the object's point of application.

Do both AC and Auto need to be turned on for the air conditioner?

The auto switch and AC switch of the air conditioner do not need to be both turned on. The AC button is the switch for the air conditioning compressor, which must be turned on for cooling in summer; Auto means automatic, that is, after this function is turned on, the air conditioner in the car will automatically adjust to a suitable temperature and wind speed. In summer, when the Auto button is pressed, the AC button will be automatically turned on; In winter, after the engine is preheated, the heat is delivered through the water circulation in the engine, so there is no need to press the AC button. Precautions for using the car air conditioner are as follows: 1. Turn off the AC during startup and rapid acceleration: Since the air conditioner (non-independent air conditioner) consumes part of the engine power when turned on, it is best to turn off the AC during vehicle startup and rapid acceleration, and then turn on the AC switch after the vehicle starts moving. This will not only prevent insufficient engine power during acceleration and startup but also save fuel. 2. Do not set the air conditioner temperature too low: In summer, many car owners like to set the temperature very low, thinking it is comfortable, but this is actually a misconception. Excessive temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and excessively low temperature may also pose a risk of arthritis for passengers in the car. Normally, the temperature inside the car should be 5°C to 6°C different from the outside temperature. 3. Control the direction of the air outlet: Based on the principle that cold air sinks and hot air rises, car owners can follow the rule of directing the air outlet upward when cooling and downward when heating.

Is Subject One All Multiple-Choice Questions?

The driving license test for Subject One is not entirely composed of multiple-choice questions. There are 100 questions in total, according to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," which include both multiple-choice and true/false questions. Each question is worth 1 point, totaling 100 points. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject One, also known as the theoretical driving test or driver's theory test, is part of the motor vehicle driving license assessment. The exam content includes theoretical driving knowledge, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. Subject One test content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One exam precautions: During the Subject One exam, candidates should pay attention to their attire—no slippers are allowed. Electronic devices and bags are prohibited in the exam hall. Bring your ID card and queue up to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the exam hall. Upon entering the exam hall, the identity verification station will assign a seat. Once seated, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay and reschedule. After the exam, queue up to collect your score report and sign it. Failure to sign renders the result invalid. There is no limit to the number of times you can reschedule the Subject One exam. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail it again, the exam process ends, and you must reschedule. For Subject Two and Subject Three, there are only five exam attempts. Subject Two and Subject Three exams must be scheduled at least ten days apart. If you fail the Subject Three safety and civilized driving knowledge test, the previously passed road driving skills test results remain valid. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One refers to the road traffic safety laws, regulations, and related knowledge test; Subject Two refers to the field driving skills test; Subject Three is divided into two parts: road driving skills and safety and civilized driving knowledge tests. The safety and civilized driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject Four."

How to Tell if an Air Filter is Dirty?

Methods to determine if an air filter is dirty: 1. Observe the engine's operating condition. If the air filter is dirty, the air intake will be insufficient, leading to incomplete fuel combustion, which causes unstable engine operation. When continuously pressing the accelerator pedal, the engine sound becomes muffled, acceleration response is sluggish, and the exhaust is thick and black. 2. Check the surface color of the air filter. If the filter paper remains gray-black after cleaning off the dust on the surface, it indicates that the filter paper can no longer be used and should be replaced immediately. The car's air filter is installed in front of the carburetor or intake pipe to filter the air entering the engine. During operation, the engine inhales a large amount of air, which contains many dust particles. Without filtration by the air filter, it can accelerate the wear of the piston group and cylinder. If larger particles enter between the piston and cylinder, it can cause cylinder scoring.
