How Long Can a Car Air Conditioner Be Turned On?

It is advisable to turn on the car air conditioner for about 15 minutes at a time. Prolonged use can lead to poor heat dissipation and damage to the car engine. In relatively enclosed environments, such as garages, it may cause carbon dioxide poisoning. It's best to use the air conditioner in open or well-ventilated areas and leave a slight window gap. When the car is idling, the engine operates at a lower speed, resulting in lower intake pressure. In this state, the engine increases the throttle opening, thereby increasing fuel injection. Shortly after entering the car, you should open the windows or activate the external circulation ventilation system to introduce fresh air. Avoid driving for extended periods with closed windows and doors, and never sleep or rest for long durations in a sealed car. As oxygen levels gradually decrease in the enclosed space, occupants may experience dizziness, nausea, and general weakness over time. Maintain air exchange between the inside and outside of the car: After purchasing a new car, it's essential to facilitate air exchange between the interior and exterior, similar to ventilating a newly renovated house, to allow harmful gases inside the car to dissipate as quickly as possible. Regularly clean the car's air conditioning system: If not cleaned for a long time, bacteria can proliferate within the system, posing health risks to passengers.

What Causes the Clicking Sound When Starting an Electric Tricycle?

The reasons for the clicking sound when starting an electric tricycle are as follows: Controller malfunction: The controller is the main device that controls occasional commutation. When the controller is damaged (mainly due to internal control program disorder or loss), the electric vehicle will make a clicking noise during startup and riding. In this case, it is necessary to replace the controller with the corresponding phase angle and brake level, or replace it with a Hall-less self-learning type controller. Throttle handle malfunction: According to electric tricycle manufacturers, when the throttle handle has poor contact or the internal Hall performance deteriorates, the electric vehicle will make a clicking noise during startup and riding. At this time, you can use the DC voltage range of a multimeter to measure the voltage between the Hall signal line and the negative pole, and the value varies depending on the throttle handle and controller.

Do electric motorcycles require a driver's license?

Electric motorcycles also require a driver's license. Here is the relevant information: Classification of electric vehicles: Electric vehicles are divided into two types, electric bicycles and electric motorcycles. The range of an electric vehicle is determined by the capacity of the battery pack. For example, a new electric bicycle with a 48V12A battery can travel about 40 kilometers, while an electric motorcycle with a 48V20A battery can also travel about 40 kilometers. Electric bicycles generally have a 350W controller and a 350W motor. With the same battery, a vehicle with higher power will have greater kinetic energy but a shorter range. Range: The distance an electric vehicle can travel is referred to as the range in the industry. It is not only related to the battery voltage and current but also to the motor type, rated power, output efficiency, and load capacity. Under normal driving conditions, if the motor efficiency reaches 80%, the vehicle can travel about 61 kilometers.

What does TRC off mean?

TRC off means the traction control system of the car is turned off. Turning off TRC has no impact on the car itself and does not affect normal driving, but the vehicle may experience wheel spin when starting on slippery surfaces. The traction control system, also known as the anti-slip system, primarily functions to maintain driving stability. Different brands have different names for the traction control system. For example, Mercedes-Benz calls it ASR, Bosch calls it ESP, Toyota calls it TRC, and Cadillac calls it TCS. Although the names vary by brand, the principles and functions are the same. The traction control system allows the vehicle to start or accelerate smoothly on poor road surfaces, ensuring a smooth acceleration performance.

What is the difference between yellow license plate vehicles and blue license plate vehicles?

The differences between yellow license plate vehicles and blue license plate vehicles: 1. Different applicable vehicle types: Yellow license plates are used for large vehicles, low-speed vehicles, trailers, ordinary motorcycles, ordinary M2 class light buses, and training vehicles; Blue license plates are used for general passenger vehicles, light motorcycles, M1 class passenger vehicles, and light trucks with a load capacity of less than 1.0 tons. 2. Different requirements for driver's licenses: Yellow license plate vehicles require a B-class license; Blue license plate vehicles require a C-class license. 3. Different requirements for operating permits: Yellow license plate vehicles need an operating permit; Blue license plate vehicles do not need an operating permit. License plates, commonly known as vehicle plates, refer to the plates hung on the front and rear of a vehicle. They are usually made of aluminum, iron, plastic, or paper, and display the vehicle's registration number, registration area, or other relevant information.
