Here are the situations that require engine replacement: 1. Complete engine water ingress: Water enters the cylinders through the intake manifold, shortening the piston stroke, which can lead to bending or breaking of the engine connecting rods. In extreme cases, broken connecting rods may fly out and penetrate the engine block. Restarting the engine under such conditions can easily cause cylinder explosion. 2. Excessive repair costs: When the repair cost is higher than or close to the replacement cost. 3. Malicious alteration of engine-related numbers: If the vehicle is stolen and the engine-related numbers are destroyed through illegal means, an application can be made to replace or restore the engine-related numbers.

Does running the AC while parked in summer affect the car?

Running the AC while parked in summer has little impact on the car. At most, it consumes a bit more fuel, but turning off the engine with the AC still running can harm the engine. Running the AC while parked increases engine load: If the owner turns off the engine without turning off the AC, although the AC stops working after the engine is off, the next time the car is started, the AC will default to its last used state and operate simultaneously with the engine. The load from the AC will be added to the engine, and excessive load on the engine can cause strain. Over time, this will inevitably reduce the engine's lifespan. Precautions for car maintenance: It is recommended to turn off the AC before reaching your destination, allowing the AC compressor to not shut off immediately. This protects the compressor and prevents damage to the engine.

What is a PCV valve?

PCV valve is a valve in the crankcase ventilation system. The following is an introduction to the PCV valve in automobiles: Composition: The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Function: Its main function is to direct the gases from the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve. This prevents phenomena such as icing at the throttle, incomplete combustion, and worsening emissions, avoiding blow-by gases from entering the atmosphere and preventing engine oil from deteriorating. Basic introduction: These blow-by gases would otherwise escape from the crankcase into the atmosphere, causing pollution. If not removed, these blow-by gases can also dilute the engine oil in the crankcase, leading to oil deterioration and premature wear of engine components.

What is the range of XPeng vehicles?

XPeng vehicles have a range of 351-520km. Here are the specific details about XPeng vehicles: 1. Use of ternary lithium batteries: Taking the XPeng G3 as an example, the XPeng G3 is a pure electric SUV equipped with a 197-horsepower motor and uses ternary lithium batteries. Most pure electric vehicles typically use ternary lithium batteries. 2. Advantages of pure electric vehicles: The motor of a pure electric vehicle operates without excess noise or vibration, providing a quieter driving experience. The power output method of the motor in pure electric vehicles also differs from that of most internal combustion engines. A typical internal combustion engine needs to reach a certain RPM to output maximum torque, whereas an electric motor does not. When a pure electric vehicle is stationary and the accelerator pedal is fully pressed, the motor can immediately deliver maximum torque.
