Signs of a bad engine include: 1. Abnormal noises during engine operation; 2. Damage to the cylinder gasket. Functions of the engine: 1. Fully combusting the fuel in the cylinders to generate power; 2. Determining the vehicle's power, fuel efficiency, stability, and environmental performance. Engine maintenance methods: 1. Use high-quality engine oil; 2. Use qualified coolant; 3. Regularly clean the radiator scale; 4. Periodically remove carbon deposits from the engine; 5. Replace the vehicle's air filter, oil filter, and fuel filter on time; 6. Check the condition of the spark plugs; 7. Maintain normal engine speed.

What to Do When the Spare Key Doesn't Work?

There are several possible reasons: The spare key's battery is dead. The vehicle's central locking system has malfunctioned. The vehicle's onboard computer data is corrupted. You need to replace the key's battery. If the car door still cannot be unlocked, you should contact the 4S store's after-sales department. Related information is as follows: 1. Storage location: The spare key for motor vehicles can be kept at home, in the office, or even in a friend's car. As long as you can quickly access the spare key when needed, there should be no problem. Note that the spare key should not be stored inside the vehicle itself. If accidentally locked inside, it can cause inconvenience. 2. Spare battery: The spare key should not be stored in damp or dark places, nor in direct sunlight. The storage location for the spare key should also contain spare batteries, as prolonged storage may cause the spare key to lose power, affecting its normal use. Otherwise, the purpose of having a spare key is defeated.

Can Automatic Parking Be Enabled in a Manual Transmission Car?

Manual transmission cars can enable automatic parking. Here is the relevant information: Automatic parking is a feature that automatically applies the brakes. Once activated, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying the operation by avoiding the use of the handbrake or electronic parking brake. Additional information: Advantages of using automatic parking: If you frequently drive in stop-and-go traffic, it can lead to foot fatigue. Automatic parking is designed to free the driver's right foot. When automatic parking is enabled and the brake is firmly pressed, the vehicle takes over the braking, allowing the right foot to rest, which can reduce driving fatigue.

Can an Overheated Radiator Damage the Engine?

"This situation can indeed damage the engine. When the temperature of the car's radiator reaches the boiling point, commonly referred to as 'the water in the car radiator boiling into hot water,' it becomes a serious issue. The radiator's temperature can be monitored through the car's coolant temperature gauge, which generally should not exceed 95 degrees Celsius. If the temperature reaches 100 degrees Celsius, driving should be stopped immediately. If the engine temperature becomes too high, the expansion of components will reduce the clearance between parts. Additionally, excessive temperature will lower the viscosity of the engine oil, leading to increased wear and tear on components and ultimately shortening the engine's lifespan. 'Boiling over' is not a minor issue and should be taken seriously by drivers, with preventive measures strengthened. When the engine temperature is too high, avoid pouring cold water onto the engine. Forgetting to add coolant when starting the car and then attempting to cool the engine by pouring cold water onto the cylinder block or cylinder head upon noticing the high temperature can have severe consequences. This may cause the engine block to crack due to sudden cooling, resulting in irreparable damage. When the coolant temperature rises (exceeding 95 degrees Celsius), the thermostat's main valve opens, and the side valve closes the bypass port. All the coolant flows through the main valve into the radiator for cooling, then to the water pump inlet, and is pumped back into the water jacket. This circulation of coolant in the cooling system is referred to as the major circulation."

Is a CVT Continuously Variable Transmission an Automatic Transmission?

CVT continuously variable transmissions are not necessarily automatic transmissions, as CVT transmissions can also be manual. Car transmissions can be divided into two main categories: manual transmissions and automatic transmissions, which correspond to manual and automatic gear shifts. Among automatic transmissions, they can be further subdivided into four types: AT (Automatic Transmission), AMT (Semi-Automatic Transmission), DTC (Dual-Clutch Transmission), and CVT (Continuously Variable Transmission). Advantages of CVT: Simple structure, compact size, and fewer parts, making the cost of mass production lower than that of conventional automatic transmissions; wide working ratio range, making it easier to achieve an ideal match with the engine, thereby improving the combustion process and reducing fuel consumption and emissions; high transmission efficiency, minimal power loss, and good fuel economy. Weaknesses of CVT Technology: For example, the transmission belt is prone to damage and cannot withstand heavy loads. These technical challenges have historically limited its application to small-displacement, low-power vehicles.
