What to Do When a Car Engine Leaks Water?

When a car engine leaks water, first identify the cause before taking any action. Here are relevant materials for solving engine leakage issues: 1. Cause Analysis: (1) If the leakage occurs at the gap between the cylinder block and cylinder head, it is caused by a leaking cylinder head gasket. (2) If the leakage comes from other parts of the cylinder head, it is due to bubbles formed during casting that have burst, causing the cylinder head to leak. 2. Solutions: (1) Check the location of the leakage. If it is at the gap between the cylinder block and cylinder head, replace the cylinder head gasket promptly. (2) If the leakage is from other parts of the cylinder head, contact the manufacturer for a claim or free replacement of the cylinder head assembly.

What to Do If Your Car Gets Struck by Lightning While Driving?

If your car gets struck by lightning while driving, follow these steps: 1. Turn off all devices: Shut down all electronic equipment in the car, including the engine, audio system, and radio. Retract the car antenna and close all windows to create a fully enclosed space. 2. Avoid touching anything: Do not touch the window handles, gear shift, steering wheel, etc. Keep your hands on your thighs, stay calm, and wait for the thunderstorm to pass. Generally, cars are less likely to be struck by lightning for the following two reasons: 1. Cars are usually not very tall and have a relatively flat shape, which makes them less likely to attract lightning. 2. The tires that connect the car to the ground have low conductivity and can be considered insulators. If an object has high resistance, it is less likely to be penetrated by lightning.

Where can the manufacturing date of a new car be found?

The manufacturing date of a car can be checked in the following two locations: 1. Below the B-pillar on the passenger side: Open the door to see this plate, which only specifies the year and month, and includes the vehicle's VIN. 2. The certificate of conformity that comes with the new car: Located in the upper right corner of the certificate, the production date here can be specified down to the exact day. It should be noted that the above two methods may not apply to all vehicle models. When a new car arrives at the dealership, there will be a paper manufacturing plate on the windshield in front of the driver's seat. This paper plate indicates the VIN and the official fuel consumption. If the date at the very bottom of the paper plate is specified down to the exact day, it can be considered as the manufacturing date. If the plate only specifies the year and month, it cannot be used as the manufacturing date.

What is the fuel consumption of the Buick Envision Plus?

The fuel consumption of the Envision Plus is 7.4 to 7.8L. Not maintaining the engine leads to higher fuel consumption: Abnormalities in the engine ignition system also significantly affect fuel consumption. Issues such as inaccurate ignition timing, leaking high-voltage wires, or weak ignition due to spark plug carbon buildup can reduce engine combustion efficiency and increase fuel consumption. Additionally, poor engine maintenance can lead to a 10% to 20% increase in fuel consumption, which is considered normal. Using the trunk as storage increases fuel consumption: The relationship between vehicle weight and fuel consumption is directly proportional. It is said that for every 10% reduction in vehicle weight, fuel consumption will decrease by a corresponding percentage.

Which is Better: Supercharger or Turbocharger?

Superchargers and turbochargers operate on the same principle, both increasing a car's power by pressurizing the air entering the engine. However, each has its drawbacks, making it difficult to definitively say which is better. Nowadays, an increasing number of high-end vehicles utilize both systems simultaneously. Below is an introduction to superchargers and turbochargers: 1. Turbocharger: It relies on the exhaust gases from engine combustion to drive a turbine, which in turn powers a compressor to force more air into the cylinders. The advantage is that it doesn’t increase fuel consumption, and the effect improves as engine RPM rises. The downside is that turbocharging requires a sufficient amount of exhaust gas to build up pressure before it becomes active. At lower engine speeds with less exhaust flow, turbo lag can occur. Additionally, after each gear shift, the air in the turbo is completely purged, requiring pressure to rebuild. Unfortunately, this lag happens precisely when the vehicle most needs acceleration—during low-speed conditions. 2. Supercharger: It connects to the engine’s crankshaft via a belt, using engine RPM to drive internal blades within the supercharger, generating pressurized air that is then fed into the engine’s intake manifold. The overall structure is relatively simple. In other words, the supercharger’s blades operate in sync with the engine’s RPM, eliminating any lag. This results in instant throttle response and linear power output that scales with engine speed. Moreover, superchargers are maintenance-free, reliable, and have a long lifespan. The drawback is that acceleration at lower RPMs is less noticeable. Additionally, due to limitations imposed by engine speed and the supercharger’s own boosting capacity, power loss at high speeds can be significant.

Do I Need to Affiliate with a Driving School to Take the Road Test in Another City?

No. According to the regulations of the Ministry of Transport, driving schools are not allowed to open branches or provide training in other locations. Here are ways to avoid enrolling in an affiliated driving school: 1. Check for certification: A legitimate driving school must have a recruitment point qualification certificate issued by the municipal auto repair management office, with a specific address and responsible person. The certificate must be displayed at the recruitment point, which is only for enrollment and not for training. 2. Contract or agreement: A legitimate driving school will sign a "Driver Training Agreement" and provide a formal invoice, while an affiliated driving school only gives a receipt. 3. Don’t believe intermediaries or instructors: Always enroll through official channels and avoid recommendations from acquaintances or intermediaries.
