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.

Reasons Why Mercedes-Benz Air Conditioning Fails to Cool

Mercedes-Benz air conditioning fails to cool for the following reasons: 1. Damaged air conditioning flap. Damage to the air conditioning flap is relatively rare. The flap is located in the middle-lower part of the dashboard. If it is damaged, it can only be replaced, although replacement is quite troublesome. 2. Dirty condenser. When the condenser is dirty, the air conditioning heat dissipation deteriorates, leading to poor cooling performance, so regular cleaning is necessary. 3. Insufficient refrigerant. Car air conditioning requires refrigerant replenishment every two to three years of use. Although car air conditioning systems are sealed, refrigerant can slowly leak. Leaks in the air conditioning pipes or condenser can also cause refrigerant loss. 4. Aged or loose compressor drive belt. The refrigerant relies on the moving parts driven by the air conditioning compressor. A loose drive belt can cause the compressor to slip, so when the air conditioning is not working properly, the engine belt should be inspected.

Why do BMWs easily stall when wading through water?

BMWs are prone to stalling when wading through water because their air intakes are positioned lower than those of other vehicle models. Here are some precautions to take when driving through water: 1. Drive in a low gear: Use a low gear (automatic transmission vehicles can engage the hill-climbing gear) and slowly pass through the waterlogged area at a steady speed while maintaining control of the steering wheel. Be aware of any potholes or gaps beneath the water-covered road. 2. Do not restart the engine after stalling: If the vehicle stalls in a waterlogged area, remember not to restart the engine. Engine stalling indicates that water has entered the cylinders. Restarting the engine can cause severe damage to the piston connecting rod assembly due to the incompressibility of water, potentially leading to complete engine failure.
