The function of the ignition system is to generate a sufficiently energetic electric spark between the two electrodes of the spark plug at the right time according to the working sequence of the cylinders. In a gasoline engine, when the compression is near the top dead center, the combustible mixture is ignited by the spark plug, thereby burning to perform external work. The combustion chamber of a gasoline engine is equipped with a spark plug. The ignition system is an important component of a gasoline engine, and its performance significantly affects the engine's power, fuel consumption, and exhaust pollution. The engine ignition system consists of all the equipment that can generate an electric spark between the two electrodes of the spark plug, usually including the battery, generator, distributor, ignition coil, and spark plug.

What does a keyless entry system mean?

Keyless entry system means starting the vehicle without taking out or turning a physical key. Simply keep the key in your bag or pocket, then press the in-car button or turn the knob to ignite the engine. One-button start is a derivative function of the keyless entry system. The keyless entry system refers to an intelligent system that utilizes advanced RFID (Radio Frequency Identification) technology and identity code recognition. With this system, the owner no longer needs to use a traditional mechanical key to unlock the car door or start the vehicle. Instead, they only need a key equipped with a smart chip to sense the vehicle. When the owner steps within a specified range, the system can identify them as the authorized driver and automatically unlock the door.

Is the AC light on for cold air or hot air?

The AC light on indicates cold air, because when the AC function is activated, the air conditioning compressor starts working. AC is short for Air Condition, which translates to air control and air conditioning in Chinese. In a car, it can be understood as the air conditioning cooling switch. When the AC light is on, the air conditioning compressor starts, increasing the engine load and consequently fuel consumption. Besides cooling, the air conditioning compressor also serves to dehumidify. Turning on the AC button helps maintain a dry interior, preventing fogging on the car windows and keeping the temperature inside the car constant.

What are the disadvantages of parallel imported cars?

The disadvantages of parallel imported cars are: 1. Potential risks of used cars: Parallel imported cars need to be imported from abroad, and some merchants may sell refurbished cars as new ones. Therefore, when purchasing a parallel imported car, it is necessary to understand the condition of the car to avoid potential risks; 2. No manufacturer warranty: Since parallel imported cars are not authorized by the manufacturer, the manufacturer naturally does not provide warranty services for these cars; 3. Possible incompatibility with fuel or parts: Due to differences in fuel quality between countries, many parallel imported cars may not adapt to local fuel, leading to various malfunctions. Therefore, it is important to clarify these aspects before purchasing.

How to Permanently Disable Auto Start-Stop?

Auto start-stop cannot be permanently disabled, but you can use techniques while driving to prevent it from engaging. Lightly pressing the brake pedal will prevent the auto start-stop from activating. When you need the auto start-stop, press the brake pedal firmly to stop the engine, then return to the normal brake pedal position; the engine will restart when you release the pedal. If the driver does not want the auto start-stop, simply brake normally, shift to neutral (N), and engage the handbrake. If the auto start-stop has already engaged, the engine will only remain off if you shift to park (P). Auto start-stop is a system that automatically controls engine shutdown and ignition. During brief stops, the engine automatically "sleeps," primarily designed for urban traffic situations like waiting at traffic lights or during traffic jams. After the engine shuts off, the electrical system can still power the engine cooling fan and cabin air conditioning, replacing the belt-driven system, to achieve fuel savings and emission reduction.
