Is It Okay to Keep the Car Running with the Air Conditioner On Without Turning Off the Engine?

1 Answers

No, keeping the engine running with the air conditioner on while parked can have negative effects on the vehicle. Here is an introduction to the impacts of running the air conditioner without turning off the engine: 1. Effects: When the car is idling, the engine speed is relatively low. Running the air conditioner can cause incomplete combustion of fuel in the engine, which may lead to carbon deposits forming in the cylinders and on the throttle valve. Additionally, keeping the engine running with the air conditioner on will increase fuel consumption. 2. Recommendations: During seasons when the air conditioner is used frequently, it is advisable to clean and disinfect the air conditioning ducts more often to improve cooling efficiency. It is also good practice to develop the habit of turning off the air conditioner before shutting down the engine.

When Does the Driver's License Point System Reset?

The driver's license point reset occurs on the anniversary of the initial issuance date, marking a 12-month scoring cycle. For example, if the license was obtained on February 1, 2019, the points would reset on January 31, 2020, restoring the full score. Additional Information: According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": 1. The cumulative scoring cycle for road traffic safety violations (i.e., the scoring cycle) is 12 months, with a full score of 12 points, calculated from the date of initial issuance of the motor vehicle driver's license. Based on the severity of road traffic safety violations, the points deducted for a single violation can be: 12 points, 6 points, 3 points, 2 points, or 1 point. 2. If a motor vehicle driver's accumulated points within a scoring cycle do not reach 12 points and all fines have been paid, the points will be cleared. If the points do not reach 12 points but there are unpaid fines, the points will carry over to the next scoring cycle.

What Causes the Impact Sound When Shifting to Reverse Gear in an Automatic Transmission?

The essence of this sound is the hard impact between the reverse gears, which occurs when shifting to reverse before the car has come to a complete stop. This causes intense wear on the gears, making them increasingly prone to gear grinding, slipping out of gear, and entering a vicious cycle, ultimately leading to major repairs. The reasons for the noise when shifting to reverse gear are as follows: 1. Reverse gear lacks a synchronizer: The synchronizer is an internal device in the transmission that ensures smooth gear engagement when shifting. If the clutch is depressed and the gear is immediately shifted, the reverse gears will collide due to speed differences, creating resistance and gear grinding noise. 2. Friction between gears during shifting: When the clutch is depressed, the reverse gears in the transmission may still be rotating for a short time. Shifting at this moment can cause gear grinding. The solution is to wait a few seconds after depressing the clutch until the rotating reverse gears have completely stopped before shifting, which will eliminate the abnormal noise. Therefore, when shifting to reverse, it is essential to ensure the car is fully stopped by pressing the brake before engaging the gear.
