What is the difference between 0w40 and 5w40 engine oil?

The difference between 0w40 and 5w40 engine oil lies in their state at low temperatures: 0W40 means the oil remains liquid at minus forty degrees Celsius and will solidify below that temperature; 5w40 means the oil remains liquid at minus thirty-five degrees Celsius and will solidify below that temperature. W40 indicates a viscosity range between 12.5 and 16.3, where 0 represents minus forty degrees Celsius and 5 represents minus thirty-five degrees Celsius. The number before W indicates low-temperature tolerance—the smaller the number, the lower the low-temperature viscosity and the better the low-temperature fluidity. The number after W represents the SAE viscosity range—the larger the number, the thicker the oil, and the higher the summer temperature it can withstand.

How to Defrost Car Windows in Winter?

Methods to defrost car windows in winter: 1. Use the car's defogging function to remove frost. After starting the car, turn on the air conditioning defogging function to blow away the frost on the windows; 2. Purchase a defogging spray. Spray the defogging agent on the inner surface of the window to prevent frost formation. One application of the defogging spray can prevent fogging for ten days; 3. If the frost is not too heavy, open the window slightly to allow air convection inside the car, which will also disperse the frost; 4. If frost forms while parked, rinse with warm water or start the car and turn on the hot air conditioning to blow on the windows for a while; 5. If frost forms while driving, wipe it off with a clean cloth or newspaper. When starting the car, slightly lower the two front windows to reduce the interior temperature. Once the car warms up, switch the mode to internal circulation, adjust the blower to hot air, and direct it to blow on the windows.

How to Turn on the Car Air Conditioner?

Method to turn on the car air conditioner: 1. Start the car, turn the temperature control knob to the cold side (blue end), turn on the AC switch and the fan (with settings 1-4), and you can also turn on the internal circulation; 2. In winter, turn the temperature control knob to the hot side (red end) and turn on the fan switch to get warm air. Method to turn off the car air conditioner: Set the fan speed switch to 0 to turn off the air conditioner. If the owner wants to turn off the cooling function while keeping the fan on, simply turn off the separate cooling switch. If you want the car air conditioner to produce heat in winter, switch the cooling/heating conversion switch to the heating area, turn on the fan switch, and adjust the fan speed to the desired setting. When heating, the cooling switch must be in the off state.

What Happens When the Controller is Broken?

When the controller is broken, the vehicle may become unable to move or experience weak driving performance, resulting in difficulty starting or pushing. The electric vehicle controller is a core component that manages the motor's start, operation, direction, speed, stop, and other electronic functions. If the controller fails, it will affect the normal use of the vehicle. Common failures in electric vehicle controllers include damage to high-power components like power transistors and capacitors. A damaged power transistor, often referred to as a 'blown transistor,' can prevent the vehicle from moving, cause the dashboard power light to flicker or stay off, and create resistance in the motor, making it hard to push. Additionally, a faulty controller may lead to short circuits, blown fuses, or tripped circuit breakers.

What does National III and National IV emission standards mean?

National III and National IV refer to exhaust emission standards. National III emission standard is the abbreviation for the third-stage national motor vehicle pollutant emission standard, while National IV emission standard is the abbreviation for the fourth-stage national motor vehicle pollutant emission standard. Compared to National III, National IV requires light-duty vehicles to reduce single-vehicle pollutant emissions by approximately 50%, heavy-duty vehicles to reduce single-vehicle emissions by about 30%, and particulate matter emissions by more than 80%. Automobile emission pollutants mainly include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. The National IV standard achieves control and reduction of vehicle emissions below specified levels through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices.

What is the principle of hybrid power?

The principle of hybrid power is that when the battery is fully charged, its energy output can meet the vehicle's requirements, and the auxiliary power system does not need to work. When the battery level drops below 60%, the auxiliary power system starts. Due to the presence of the battery pack, the engine operates under relatively stable conditions, thereby improving its emissions. The power system of a hybrid electric vehicle mainly consists of a control system, drive system, auxiliary power system, and battery pack. Hybrid power refers to the combination of fuel (gasoline or diesel) and electric power. A hybrid vehicle uses an electric motor as an auxiliary power source to assist the engine. The electric motor assisting the engine can generate strong power during normal driving.
