Do you need to turn on the A-C for car air conditioning heating in winter?

You do not need to turn on the A-C for car air conditioning heating in winter. Here are the reasons why it is unnecessary to turn on the A-C: Only the blower is needed for heating in winter: Based on the heating principle of fuel vehicle air conditioning, the compressor is not required to work for heating in winter. Therefore, theoretically, there is no need to turn on the A-C. From a power consumption perspective, heating only requires the blower to be turned on, which consumes minimal power. Turning it on will increase fuel consumption: However, if the A-C switch is turned on, the compressor will consume additional energy when powered on. Although it will not blow cold air, it will unnecessarily increase power consumption and indeed lead to higher fuel consumption.

What Does Engine Anti-Theft System Authentication Failure Mean?

Engine anti-theft system authentication failure means that the car key is not detected. The reasons for this are: 1. The car key battery is dead; 2. Severe signal interference in the surrounding environment; 3. Damage to the key's adjustment unit; 4. The key code does not match. An engine is a machine that can convert other forms of energy into mechanical energy, and it is suitable for power generation devices. Precautions for engine maintenance include: 1. Using high-quality engine oil can provide lubrication, cleaning, cooling, sealing, and wear reduction; 2. Using qualified coolant; 3. Regularly cleaning the radiator scale; 4. Periodically removing carbon deposits from the car; 5. Changing the car's three filters on time.

What engine does the Verna use?

The engine of the Verna is produced at the engine factory located in Shunyi, Beijing, and is a domestically manufactured engine. The Verna's engine model is G4FA, with a maximum output power of 73kW, maximum torque of 132Nm, and maximum horsepower of 100, paired with a CVT continuously variable transmission. For daily maintenance of the Verna's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent faults, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.
