Is Quattro a Full-Time Four-Wheel Drive or an On-Demand Four-Wheel Drive?

1 Answers

Quattro mostly adopts full-time four-wheel drive in National V emission standard models, while it uses on-demand four-wheel drive in National VI emission standard models. Introduction to Full-Time Four-Wheel Drive: It refers to a driving system where all four wheels independently propel the vehicle at all times. In English, "All Wheel Drive" is abbreviated as "AWD" to distinguish it from 2WD (which includes FWD and RWD). Function of Full-Time Four-Wheel Drive: It means that the vehicle maintains a four-wheel drive form throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels in a fixed proportion. This driving mode ensures good off-road and handling performance at all times, but it cannot adjust torque distribution based on road conditions and has relatively higher fuel consumption.

China IV vehicles are equipped with three-way catalytic converters. Here are the specific details: 1. Three-way catalytic converter: The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. When high-temperature exhaust gases pass through the purification device. 2. Principle: When high-temperature exhaust gases pass through the purification device, the purifying agents in the three-way catalytic converter enhance the activity of CO, HC, and NOx gases, promoting certain oxidation-reduction chemical reactions, where CO oxidizes at high temperatures to become colorless.

Does Opening Car Doors While Both Vehicles Are Stationary Count as a Traffic Accident?

This is not a traffic accident. If one of the vehicles is parked illegally, the owner of that vehicle is responsible. Below are the handling methods for illegal parking: 1. On-site illegal parking penalty: For violations of the road traffic safety law regarding motor vehicle parking regulations, if the driver is present, the traffic police can point out the violation, issue a verbal warning, and order the driver to leave immediately.

Off-site illegal parking penalty: If the driver is not present, in addition to issuing a fine ticket, if the parked vehicle obstructs the passage of other vehicles or pedestrians, the traffic police department has the authority to tow the vehicle to a location that does not obstruct traffic or to a parking location designated by the traffic management department of the public security organ.
