What is the battery capacity of the Tang DM?

The Tang DM is a DM dual-mode electric vehicle. Below are the detailed specifications: Introduction: The Tang DM can operate using either fuel or electricity. The mid-range and lower configurations are equipped with a 20kWh ternary lithium battery pack, providing a range of 80km. The high-end and above configurations feature a 24kWh ternary lithium battery pack, offering a range of 100km. Currently, it boasts the longest pure electric range in its vehicle class. BYD's DM-i Engine: The core component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid dedicated engine, which comes in two versions: a 1.5L engine primarily used in the Qin PLUS and Song PLUS, and a 1.5T turbocharged engine for larger models like the Tang DM-i. These models feature two key components: the EHS dual-motor system and the DM-i Super Hybrid dedicated Blade Battery. Along with a series of vehicle control systems, engine control systems, motor control systems, and battery management systems, they form the Super Hybrid system. Most importantly, all these core components and key technologies are entirely independently developed by BYD.

What engine is used in the Volvo C70?

Volvo C70 uses a total of three engines, which are a 2.3-liter turbocharged engine, a 2.4-liter naturally aspirated engine, and a 2.5-liter turbocharged engine. The 2.3-liter turbocharged engine is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. This engine produces 245 horsepower and a maximum torque of 330 Nm, with the maximum torque achieved at 2400 rpm and the maximum power at 5400 rpm. The 2.4-liter naturally aspirated engine is also equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head and block, producing 170 horsepower and a maximum torque of 230 Nm, with the maximum torque achieved at 4400 rpm and the maximum power at 6000 rpm. The 2.5-liter turbocharged engine is equipped with a VIS (Variable Inertia Intake System) and uses an aluminum alloy cylinder head and block, producing 230 horsepower and a maximum torque of 320 Nm, with the maximum torque achieved between 1500 and 5000 rpm and the maximum power at 5000 rpm.

What are the functions of a transmission?

The functions of a transmission are: 1. Changing the transmission ratio: Altering the transmission ratio to expand the range of torque and speed variations in the driving wheels. 2. Enabling reverse driving: Allowing the vehicle to move backward while the engine's rotation direction remains unchanged. 3. Facilitating gear shifting: Utilizing neutral gear to interrupt power transmission, enabling the engine to start, change speed, and making it easier to shift gears or output power. Vehicle transmissions are divided into manual and automatic types: 1. Manual transmission: A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. A manual transmission, also known as a manual gearbox, requires the driver to manually shift the gear lever to change the gear engagement positions inside the transmission, altering the transmission ratio to achieve speed changes. 2. Automatic transmission: An automatic transmission uses planetary gear mechanisms to change speeds. It automatically adjusts the gear ratio based on the degree of throttle pedal input and changes in vehicle speed. The driver only needs to control the speed by operating the accelerator pedal.

How to Replace the Air Conditioning Filter in a Golf?

Golf air conditioning filter replacement steps are as follows: 1. First, remove the air conditioning unit and pull out the entire glove box. 2. Locate the air conditioning filter cover at the bottom of the center console, and lift the cover to reveal the air conditioning filter inside. 3. Take out the old filter and replace it with a new one. Here are some precautions regarding air conditioning filter replacement: 1. After prolonged use, the activated carbon filtration function of the air conditioning filter will diminish. Therefore, you can purchase a compatible air conditioning filter from the auto parts market for replacement. 2. If the airflow from the air conditioner significantly decreases, the air conditioning filter may be clogged. First, clean the filter, and replace it if necessary. 3. The cleaning frequency depends on road conditions (such as dusty roads, etc.). 4. The air conditioning filter should be correctly installed in its position. 5. If the air conditioner is used while the air conditioning filter is removed, it may degrade the dustproof performance and affect the air conditioner's performance.

What is the external air circulation symbol for vehicle air conditioning?

The circulation symbol is a circular arrow within a car graphic; while the external circulation symbol features an arrow entering the vehicle from outside. However, many current vehicle models no longer have a dedicated external circulation button. This doesn't mean the function is absent, but rather manufacturers simplify the design by making external circulation the default mode when the internal circulation button isn't activated. Additional information is as follows: 1. External circulation mode: This mode uses a fan to draw outside air into the cabin, meaning the air passage between exterior and interior remains open. The fan blows external air, and even when the fan is off, moving vehicles still allow airflow into the cabin to replenish fresh air. The sensation of airflow with the fan off often indicates active external circulation settings. 2. Internal circulation mode: This mode seals the airflow passage between interior and exterior. Without the fan, no air circulates, and when activated, the fan only recirculates existing cabin air. Internal circulation primarily serves to effectively block external pollutants like dust, harmful gases, smoke, road dust, strong odors, or exhaust fumes from preceding vehicles in dense traffic. It also helps maintain cabin temperature.

What to Do When There's a Layer of Frost on the Windshield?

When there is a layer of frost on the car windshield, simply start the car and wait for the engine to warm up. Then, adjust the air conditioning to direct airflow toward the windshield. After a few minutes, cracks will begin to appear in the frost. At this point, using the windshield wipers along with windshield washer fluid can quickly remove the frost. Additional Tips: 1. After using the car for the day, do not immediately lock the car and leave. Instead, open both doors to allow ventilation until the interior temperature drops to match the outside temperature before locking the doors and leaving. The next morning, there will definitely be no frost on the windshield. Even if it snowed the night before, simply brushing off the snow from the windshield will prevent ice formation, allowing you to drive immediately. 2. The reason the windshield ices over is that after the occupants leave, residual heat inside the car keeps the windshield temperature higher than the outside. This causes moisture in the air or snowflakes to melt upon contact with the windshield. Once the interior and exterior temperatures equalize, the melted snow begins to freeze.
