Is It Serious If a Car's Chassis Gets Submerged in Water?

What Causes the Car to Fail to Engage Gear When Starting with the Clutch Pedal Pressed?

The reasons why a car fails to engage gear when starting with the clutch pedal pressed are as follows: 1. Clutch cable failure: Some manual transmission cars still use cables to control the clutch. The outer sheath of the cable can easily crack, leading to difficulty in engaging gears due to no clutch. This issue is relatively simple to fix—just replace the cable. 2. Excessive gear self-locking force on the clutch side: This makes it difficult to shift in and out of gears. In such cases, it is recommended to go to a repair shop to adjust the clutch cable and gear lock. 3. Clutch master cylinder failure: The clutch hydraulic master cylinder may experience pressure loss or oil leakage during use, resulting in the inability to engage gears when pressing the clutch pedal. The solution is to replace the clutch master cylinder at a service station, followed by bleeding the air from the system. 4. Transmission failure: Insufficient transmission fluid, stuck transmission shift mechanism, or failure of a certain gear or shift fork can all cause difficulty in engaging gears or prevent the car from shifting into gear.

Can a sedan accommodate 5 people?

Each vehicle model is different, and the passenger capacity varies. The specific number of passengers allowed depends on the vehicle's documentation, which states the approved seating capacity. Some cars allow 2 people, some 4, and others 5. Below is relevant information: 1. Regulations: "Road Traffic Safety Law": Driving a family car with passengers exceeding 20% of the approved capacity results in a 3-point deduction; exceeding 20% results in a 6-point deduction. This means that if a sedan approved for 5 people carries 6, exceeding 20%, it incurs a 6-point penalty—as severe as running a red light. Note that traffic laws do not distinguish between adults and children; 4 adults and 1 child still count as 5 people. 2. Precautions: When driving a family car with children under 4 years old, failing to use a child safety seat will result in a fine. Since these new traffic regulations were enacted, penalties have been strengthened not only for overloading but also for other violations. In short, always pay attention to traffic laws—once you get used to them, they won’t feel overly strict.

Is It Normal for Water to Spray from the Car Exhaust Pipe?

During the operation of a car engine, it is normal for water to occasionally spray out from the exhaust pipe. This is a common physical phenomenon. Below is an introduction to the relevant knowledge about water spraying from the exhaust pipe: 1. Principle: After gasoline combustion, the exhaust pipe primarily emits carbon dioxide and water. Due to the high temperature of the engine, water is initially in the form of vapor. When this vapor encounters the cold outside air, it condenses into small water droplets, which may spray out. 2. Precautions: Excessive water inside the exhaust pipe can damage the oxygen sensor in the catalytic converter, leading to inaccurate fuel supply to the engine and affecting the car's performance. Additionally, prolonged retention of water droplets in the exhaust pipe can accelerate pipe corrosion.

What is the Difference Between Supercharging and Turbocharging?

Here are the specific differences between supercharged engines and turbocharged engines: 1. Structure: The supercharger has a simpler structure than the turbocharger. The higher the engine speed, the greater the boost pressure, and there is no turbo lag phenomenon associated with turbocharging. The turbocharger has a more complex structure and a higher failure rate compared to the supercharger. 2. Fuel consumption: The supercharger is driven by a belt, which consumes engine power, so it is not as fuel-efficient as the turbocharger. The turbocharger provides strong boost pressure, allowing even small-displacement engines to deliver powerful performance while also being more fuel-efficient.

Is It Normal to Feel Suction When Opening the Oil Cap?

It is normal for the oil cap to suck in air when opened, because after the engine starts, it operates under a negative pressure state (no air can enter). Therefore, when the oil cap is opened, suction is likely to occur. Especially for some new cars, due to the excellent sealing of the oil cap, the effect of negative pressure is even more noticeable. Here are some related explanations: 1. Effects of Excessive Suction: If there is a strong suction when opening the oil cap, accompanied by a noticeable abnormal sound, it is likely due to a damaged exhaust gas recirculation (EGR) valve, which fails to control the amount of exhaust gas recirculation. This not only affects the stability of the intake but can also cause idle vibration. In such cases, it is necessary to promptly replace the EGR valve to resolve the issue of excessive suction. 2. Reasons for Suction When Opening the Oil Cap: Poor sealing of the oil cap; damaged EGR valve; the oil cap was tightened too much during car maintenance.

What lights should be used on the highway?

Driving on the highway late at night requires the use of high beams. Here is a related introduction to the use of lights when driving on the highway: 1. Reason for using high beams: If you use low beams, when you see an obstacle, switching to high beams provides earlier illumination, allowing you to react in advance and reach your destination safely. 2. Use of lights for night highway driving: The use of lights for night highway driving depends on the situation. If you are very close to the vehicle in front, you should not use high beams, as they will reflect directly into the rearview mirror of the vehicle ahead, potentially blinding the driver and creating a hazard. However, if you maintain a sufficient distance from the vehicle ahead and your high beams do not affect them, using high beams is acceptable.
