Where is the Envision's external circulation button?

auto right side second button press once light on is external circulation, light off is internal circulation: 1. Location: On the car's air conditioning panel, there are two simplified vehicle pictograms. One shows an arrow circling inside the vehicle body - this is the internal circulation button. The other shows an arrow blowing inward from the windshield - this is the external air intake or external circulation mode button. Some vehicles have mechanical lever-type AC controls with similar pictogram markings at both ends of the lever, serving the same function. The Buick Envision defaults to external circulation being enabled: 2. External circulation maintains airflow: In external circulation mode, the fan draws outside air into the vehicle, maintaining airflow between the exterior and interior. The fan blows outside air, and even when the fan is off, driving motion creates airflow into the cabin to replenish fresh air, which explains why you might feel airflow even with the fan turned off.

What is the difference between 2.0t and 1.5t engines in cars?

The differences between 2.0t and 1.5t engines in cars are as follows: 1. Different fuel consumption: On ordinary roads, considering the vehicle's own weight, the 1.5t engine consumes more fuel than the 2.0t during the initial acceleration phase because turbo engagement requires RPM support. On highways, the 2.0t engine has higher fuel consumption, while the 1.5t, with its smaller displacement, is more economical. 2. Different comfort levels: The 1.5t engine may experience some jerkiness when driving in congested areas as the turbo alternates between working and not working. In contrast, the 2.0t engine operates more smoothly under such conditions. 3. Different maintenance costs: The maintenance cost for the 2.0t engine is relatively higher. If you prioritize power, it is recommended to purchase a 2.0t engine. However, from a maintenance perspective, the 1.5t engine is more advisable.

What does the red flashing of the Passat's temperature gauge indicate?

Passat's temperature gauge flashing red indicates: there is a problem with the engine cooling system or a lack of coolant. Taking the 2020 Passat as an example, it belongs to the mid-size car category, with body dimensions of: length 4933mm, width 1836mm, height 1469mm, a wheelbase of 2871mm, and a curb weight of 1470kg. The 2020 Passat features a front suspension of MacPherson independent suspension and a rear suspension of multi-link independent suspension. It is equipped with a 1.4T turbocharged engine, delivering a maximum horsepower of 150PS, a maximum power of 110kW, a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.

Are the low beam and high beam the same bulb?

Depending on the vehicle model, the bulb types for low beam and high beam may vary. Some vehicles have integrated low and high beam bulbs, while others have separate bulbs for each. The method to turn on the low beam is: 1. Locate the light control switch on the left side of the steering wheel; 2. Rotate the switch forward one notch to turn on the dashboard lights; 3. Rotate another notch to activate the low beam. Situations where low beams should be used include: 1. Driving in areas without streetlights at night, during dusk when it's dark, or at dawn; 2. During fog, snow, or heavy rain when visibility is affected; 3. When driving on roads with insufficient lighting.

Does replacing the anti-collision beam count as a damaged vehicle?

Replacing the anti-collision beam does not necessarily classify a car as a damaged vehicle. A damaged vehicle refers to a car that has suffered damage from non-natural wear and tear incidents, leading to a decline in mechanical performance and economic value. Typically, this refers to vehicles with structural damage, including those affected by flooding or fire, which fall under the category of special damaged vehicles. The anti-collision beam is a device used in motor vehicles to mitigate collision impact by absorbing collision energy. It consists of a main beam, an energy-absorbing box, and mounting plates that connect to the car. These components effectively absorb collision energy during low-speed impacts, significantly reducing the force of the impact on the vehicle's body weight and providing excellent protection.

What can be extracted from a three-way catalytic converter?

A three-way catalytic converter can extract platinum (Pt), rhodium (Rh), and palladium (Pd), which are platinum group precious metals. The function of a three-way catalytic converter is to react with the exhaust gases emitted by a car, catalyzing or altering the nature of harmful emissions, thereby reducing their pollution. Methods for extracting precious metals from a three-way catalytic converter: Grind the catalyst inside the three-way catalytic converter into powder, as the precious metals are coated as a layer of catalyst inside; burn the powdered catalyst at high temperatures; add a sodium borohydride aqueous solution and boil to 100 degrees Celsius, then add a sodium chlorite hydrochloric acid solution; maintain the temperature around 100 degrees Celsius; after 3 hours, filter; add a 10% HCl aqueous solution for acid washing and water washing, keeping the temperature around 100 degrees Celsius. After separation, platinum group metals can be obtained. Precautions for using a three-way catalytic converter: Do not use leaded gasoline; avoid prolonged idling (open-loop control state); avoid sudden changes in engine speed; do not set the ignition timing too late; do not pull out the high-voltage wire for extended periods to test for sparks; when measuring cylinder pressure, disconnect the central control connector of the fuel pump to stop the injector from spraying fuel into the cylinder; if any cylinder is found to be malfunctioning, stop the vehicle promptly to inspect and rectify the issue, etc.
