Does using P gear with air conditioning on affect the car?

Leaving an automatic transmission car in P gear with the engine running and air conditioning on for a long time does not damage the car. P gear is the most common gear in automatic transmission models, usually located at the frontmost position of the gear shift console, in front of the R gear, designed to lock the axle when the car is stationary on a slope. However, when the vehicle is idling in place, the gasoline in the engine may not burn completely. If this happens frequently over a long period, it can increase the formation of carbon deposits in the engine, and relatively, fuel consumption may also increase. In addition, if you rest in the car with the air conditioning on in a confined environment, a large amount of gas can enter the car through the vehicle's ventilation system. Staying in the car for an extended period under such conditions can easily lead to carbon monoxide poisoning. If the driver must rest in the car, it is advisable to first park the car in an open and ventilated location. Then, lower the window by about two fingers' width for ventilation, and finally switch the air conditioning mode from internal circulation to external circulation to ensure proper air flow inside the car.

Will traffic violations with temporary license plates be photographed and fined?

Temporary license plate violations will result in points deduction and fines. Introduction to temporary license plates: Temporary license plates refer to paper motor vehicle license plates that allow temporary road use of motor vehicles, mainly issued by public security vehicle management departments for newly purchased vehicles before formal registration. There are four types: temporary license plates for administrative jurisdictions, temporary license plates for cross-administrative jurisdictions, temporary license plates for testing purposes, and temporary license plates for special-type motor vehicles. Regulations related to temporary license plates: New cars using temporary license plates must not exceed 15 days, and owners should promptly apply to the vehicle management authority for formal license plates. After expiration, they may face penalties such as vehicle impoundment, fines, and points deduction.

What are the hazards of parking in neutral with the handbrake engaged?

Parking a car in neutral with the handbrake engaged is possible and generally does not cause harm to the vehicle. However, this practice is not recommended, especially on inclined roads. Below is relevant information about the handbrake: Handbrake Principle: The handbrake, technically known as an auxiliary brake, operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force. Prolonged use of the handbrake can lead to plastic deformation of the steel cable. Since this deformation is irreversible, it reduces effectiveness over time and increases the handbrake's travel distance. A return spring works in conjunction with the handbrake. When the handbrake is engaged, the spring stretches; when released, it returns to its original length. Long-term use can also cause deformation in the spring. Importance of Proper Use: The handbrake is a frequently used system. Proper and correct usage ensures smoother operation in the future, extends the adjustment cycle, and reduces maintenance and replacement costs.

Why does the car still roll when in N gear?

If the car still rolls when in N gear, it's because the wrong gear was selected. When parking, you should shift to P gear. N gear is neutral and does not have a parking function, while P gear is the actual parking gear. Below is an introduction to the related gear functions: P gear: Parking lock position. When the gear lever is moved to this position, the drive wheels are mechanically locked. The gear lever can only be moved to this position after the car has come to a complete stop. To move the gear lever out of this position, you must press the brake pedal and turn on the ignition. R gear: Reverse position. Move the gear lever to this position when reversing. The gear lever can only be moved to this position after the car has come to a complete stop. N gear: Neutral position. When the gear lever is moved to this position, the transmission does not engage any gear. After shifting to this position, no power is transmitted to the wheels, and the engine's braking function cannot be utilized.

Does stepping on the accelerator in P gear have any impact?

Stepping on the accelerator in P gear has no impact on the vehicle. The P gear in an automatic transmission vehicle is the parking gear. In this gear, pressing the accelerator does not transfer power to the transmission system, meaning no substantial damage is involved. It is similar to stepping on the accelerator in neutral, where the engine operates in an idle state. When the vehicle is parked in P gear, the mechanical lock gear teeth secure the transmission output, effectively disengaging the engine from the transmission. There is no power transfer, and revving the engine only increases its RPM without transmitting power to the transmission. Like neutral (N gear), the engine spins freely, and the vehicle does not move. P gear is a special neutral position that mechanically locks the transmission output shaft to immobilize the vehicle. Its primary function is to act as a parking brake, preventing the vehicle from moving. For practical safety reasons, car manufacturers place the P gear in the first position on the gear selector and configure internal mechanisms to ensure the ignition key can only be removed when the gear lever is in P gear. Therefore, P gear is specifically designed for long-term parking in automatic transmission vehicles. Occasionally stepping on the accelerator in P gear will not harm the vehicle, but prolonged operation can cause the engine temperature to rise rapidly. Without cool air intake, the radiator's cooling efficiency significantly decreases, potentially leading to severe issues such as burning the piston's bearings (big and small ends). Additionally, it can negatively affect belts and gears.

Can You Release the Clutch Immediately After Shifting to Second Gear?

You cannot directly release the clutch after shifting to second gear. After shifting up to second gear, you should gently lift the clutch and slowly apply throttle—do not release the clutch immediately. Releasing the clutch too quickly: After pressing the clutch and completing the gear shift, the car's speed has not yet increased, so the clutch must be released gradually. Releasing the clutch too quickly can cause the engine to stall. You can wait until the clutch is fully released before applying throttle, as coordinating the clutch and throttle requires relatively advanced skill. Proper clutch operation: Only press the clutch pedal when braking at speeds below 20 km/h. Pressing the clutch pedal at higher speeds does not aid braking effectiveness. Of course, during emergency braking, you should simultaneously press both the brake and clutch.
