Why doesn't BYD support CarPlay?

BYD does not support CarPlay because its original in-car system is essentially a tablet computer equipped with a full range of apps. CarPlay is an in-car system launched by Apple Inc., which seamlessly integrates users' iOS devices and iOS experience with the dashboard system. CarPlay only supports iPhones with Lightning ports. Although iPads also support this interface, Apple has not included iPads as hardware devices supported by CarPlay. Ways to control CarPlay: Siri: You can communicate with the car through Siri, instructing it on what to do next. You can also hear the system read out messages received on your phone and reply using voice dictation. Touchscreen display: Some cars that support CarPlay come with a touchscreen display, allowing you to open or close apps on a relatively simple home screen. Physical buttons: Cars equipped with physical buttons can also control CarPlay as one of the methods.

What is the difference between China V and China VI?

The difference between China V and China VI can be summarized in one sentence: China VI has higher tailpipe emission standards than China V. Of course, China VI is further divided into China VI a and China VI b. The transition from China V to China VI a in terms of emission standards only involves a difference in carbon monoxide emissions, which decreased from 1000mg/km to 700mg/km, a reduction rate of 30%. As for the China VI B standard, carbon monoxide emissions are reduced by 50% compared to China V, and other pollutants have also been significantly reduced.

What does CVT continuously variable transmission mean?

CVT is a type of car transmission, also known as a continuously variable transmission, which literally translates to continuously variable transmission. CVT does not have specific gears, but the change in speed ratio is different from the gear-shifting process of an automatic transmission—it is continuous, so power transmission is sustained and smooth. The advantage of CVT is that it has a wide working speed ratio range, allowing it to operate at an economically ideal speed, reducing fuel consumption. The disadvantage is that the steel belt cannot transmit excessive torque, otherwise it will slip.

What are the differences between a three-cylinder engine and a four-cylinder engine?

The differences between a three-cylinder engine and a four-cylinder engine include the number of cylinders, structure, distribution, engine balance, fuel consumption, weight, and low-speed torque. A three-cylinder engine has one fewer cylinder than a four-cylinder engine. Below are the detailed explanations: Number of cylinders: A three-cylinder engine has three cylinders; a four-cylinder engine has four cylinders. Structure: A three-cylinder engine has a simpler structure, smaller size, lighter weight, and easier layout; a four-cylinder engine has a relatively more complex structure. Distribution: The three pistons in a three-cylinder engine cannot move up and down simultaneously, making it difficult to suppress vibrations; in a four-cylinder engine, cylinders 1 and 4, and cylinders 2 and 3 move up and down simultaneously, which helps suppress vibrations to some extent. Engine balance: Due to having one fewer cylinder, a three-cylinder engine performs worse in terms of engine balance control compared to a four-cylinder engine. Weight: A three-cylinder engine is smaller in size and lighter in weight; a four-cylinder engine is relatively larger in size and heavier in weight. Fuel consumption: A three-cylinder engine consumes less fuel; a four-cylinder engine consumes relatively more fuel. Low-speed torque: A three-cylinder engine has greater low-speed torque; a four-cylinder engine has relatively lower low-speed torque. A three-cylinder engine consists of three cylinders arranged on a single block, sharing a common crankshaft to output power. Its main function is to convert chemical energy into mechanical energy. A four-cylinder engine, also known as a four-cylinder engine, is a machine that converts one form of energy into another more useful form of energy. The working principles of three-cylinder and four-cylinder engines are the same. They convert the chemical energy of gasoline (or diesel) into thermal energy. The combustion and expansion of the sealed cylinder's gas mixture push the piston to perform work, converting thermal energy into mechanical energy.

How should the rearview mirrors be adjusted?

Left rearview mirror: The optimal adjustment angle is to have the road environment occupy most of the mirror surface, with only 1/4 of the car body visible. Right rearview mirror: Similarly, the road environment should occupy most of the mirror surface. Since the right rearview mirror is farther from the driver's line of sight, position the vanishing point of the road at the top of the mirror, with the car body also showing 1/4. Interior rearview mirror: Simply adjust it manually so that the distant horizon is centered in the mirror.

What are the reasons why the BYD Song USB port cannot recognize the USB flash drive?

The BYD Song USB port may not recognize the USB flash drive due to a loose connection at the USB port. Once the port is loose, the USB may fail to recognize the device, or the USB flash drive itself may be damaged. First, check if the USB flash drive is faulty. If it is not faulty, plug it into a computer to check the format of the USB flash drive and reformat it to NTFS format. If it still cannot be read, the car's USB port may be faulty and requires repair at a professional auto repair shop. Precautions for using the car USB port: Do not unplug the USB flash drive while it is reading, writing, or saving data to avoid damaging the USB flash drive and the port. The USB flash drive also requires driver loading during use. If the USB flash drive or phone is occasionally not recognized, try reconnecting it by unplugging and plugging it back in. If the USB flash drive is not used for a long time, unplug it promptly to prevent accelerated aging of the USB flash drive. Additionally, the host system frequently reads and writes to the USB flash drive, which may affect the host's operating speed. When the vehicle is on a bumpy road, vibrations may cause an unstable USB connection, leading to disconnection. Please wait patiently for the system to reconnect or try reconnecting the USB flash drive or phone by unplugging and plugging it back in.
