Generally, car engines in the market are divided into naturally aspirated engines and turbocharged engines. The naturally aspirated engine is a traditional type with lower manufacturing costs, simpler processes, and relatively low failure rates. Vehicles equipped with naturally aspirated engines typically exhibit average performance in terms of power. The turbocharged engine is a commonly used type known for its strong power output and high fuel efficiency. Compared to naturally aspirated engines, vehicles with turbocharged engines tend to have higher maintenance and repair costs.

Will the Car Automatically Lock if the Key is Inside?

If the vehicle is equipped with an automatic locking or anti-theft system, the car doors may automatically lock when the key is left inside. However, vehicles with keyless entry systems will not experience this issue. Solutions include using a spare key or contacting a locksmith. Automatic Locking: The design purpose of automatic locking is to prevent vehicle theft and enhance driving safety. After closing the door, the system will automatically lock the doors after a specified period to prevent situations where the owner forgets to lock the car after turning off the engine or where the doors accidentally open during driving. Keyless Entry: Keyless entry vehicles typically feature push-button start, eliminating the need to insert or remove the key. Therefore, the key is usually carried by the owner, significantly reducing the chance of leaving it inside the car. Additionally, the door handles of keyless entry vehicles often have touch-sensitive fingerprint functions, so even if the key is left inside, there is no need to worry. Prevention Methods: When exiting the vehicle, always turn off the engine, remove the key, and keep it with you. If you must exit the vehicle while it is still running, ensure the handbrake is engaged, the door is not fully closed, or the window is rolled down. Furthermore, when retrieving items from the trunk, avoid placing the key inside the trunk.

Can Auto Hold and Engine Start-Stop Be Used Together?

Auto Hold and Engine Start-Stop can be used together. Auto Hold refers to an automatic braking function. After activating this function, for example, when stopping at a traffic light, it is equivalent to not having to pull the handbrake, avoiding the use of the handbrake or electronic handbrake and simplifying operations. For automatic transmission models, it also eliminates the need for frequent shifting between D to N or D to P. Engine Start-Stop automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts it when it's time to move forward again. Auto Hold and Engine Start-Stop are two different functions, and car owners should not confuse them. For instance, when preparing to park, do not press the Engine Start-Stop button thinking it's Auto Hold, as this may lead to forgetting to engage the handbrake and causing the vehicle to roll.

Is it a big deal if the car's valve cap is lost?

It won't have any impact. If the tire loses its valve cap, it won't cause air leakage because the valve itself is what functions. Here are the specific reasons: 1. Valve function: As long as the valve is intact, there will be no air leakage. The valve cap only protects the valve core, preventing dust, water, oil, etc., from damaging the valve core's sealing rubber, thereby extending the valve core's service life. 2. Valve cap function: However, it is safer to have the valve cap installed as it can extend the valve core's service life and also looks more aesthetically pleasing. 3. Safety note: After all, tires are related to driving safety and personal safety, so one must not be careless about them.

What does the PVC valve in a car mean?

The PVC valve in a car is a component of the Positive Crankcase Ventilation (PCV) system in the engine, consisting of a valve body, valve, valve cover, and spring. Below are the main functions of the PVC valve in a car: 1. Conduit: It directs 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. 2. Preventing various issues: It helps avoid phenomena such as throttle icing, incomplete combustion, and worsening emissions, while also preventing blow-by gases from entering the atmosphere and preventing engine oil from deteriorating.

Why is valve clearance necessary in the valve train?

Here are the reasons why valve clearance is necessary in the valve train: 1. Prevent gas leakage: If there is no clearance when the valve train components expand due to heat, it may push the valve open when it should be closed, causing combustion chamber leakage. 2. Affect power output: Excessive valve clearance will result in insufficient valve opening, affecting air intake; insufficient clearance will prevent the valve from closing tightly, causing leakage and affecting engine power. 3. Adjustment method: Adjust the adjusting screw at the rear of the valve rocker arm, measuring the clearance between the rocker arm head and the valve stem head. During adjustment, the tappet should be positioned at the base circle of the camshaft lobe, which is when the valve is in the closed position.
