What kind of oil should be used under the spare tire?

Unclean oil contains various chemical substances that can corrode tire rubber upon contact, thereby damaging the tire. Tire maintenance methods: For tire maintenance, use tire wax, also known as tire renovator or tire blackener, which comes in both liquid and paste forms. Tire maintenance tips: Maintain tire pressure at the standard level and regularly service the vehicle. Non-standard tire pressure can lead to excessive tire wear and cause blowouts. The vehicle owner should be fully aware of the tire wear indicators and the tire production date, and ensure regular vehicle maintenance. Before driving on highways, check the tire condition. At the same time, avoid using the spare tire for extended periods.

What is the maximum torque speed range?

Maximum torque speed range is from 1800 rpm to 4000 rpm. Speed range: "Maximum torque speed 1800-4000 rpm": refers to the maximum torque value within the entire engine speed range, which occurs between 1800 rpm and 4000 rpm. Range: Maximum torque usually appears in the medium to low speed range of the engine. As the speed increases, the torque will decrease. Torque: The unit for maximum torque speed is rpm, indicating the engine speed at which maximum torque occurs. The maximum torque of an engine is related to the design of the intake system, fuel supply system, and ignition system. At a certain speed, when these systems achieve optimal performance matching, the maximum torque can be reached.

How to Activate the Four-Wheel Drive on the Audi Q5L?

Audi Q5L is equipped with an on-demand four-wheel drive system, namely Audi's Quattroultra four-wheel drive system, which automatically switches between two-wheel drive and four-wheel drive modes based on road conditions without requiring manual activation. Here is the relevant content introduction: The Audi Q5L replaces the previous Torsen center limited-slip differential with a multi-plate clutch-type center differential, transitioning from a full-time four-wheel drive to an on-demand four-wheel drive system. Comparatively, the on-demand four-wheel drive results in a 4kg weight reduction and a 5% improvement in the efficiency of the four-wheel drive system, which also provides the Audi Q5L with better fuel economy.

What is the ECT in a car?

The ECT mode in a car is a rapid acceleration mode, similar to a sports racing mode. It can quickly increase the engine's RPM, but fuel consumption will significantly increase. It is mostly used for highway driving. When activated, the throttle feels more responsive and direct, and the gear shift timing typically occurs above 4500 RPM. The usage of ECT is as follows: 1. When the ECT switch is turned on, the transmission mode switches to sport mode. In this mode, the transmission downshifts more frequently and responsively. Additionally, since the gear is limited to a lower range, the engine RPM increases accordingly, torque output rises, and the vehicle's power performance is greatly enhanced. 2. When the ECT switch is turned off, the transmission will switch back to standard mode. In this mode, the transmission's shift logic will determine the timing of gear shifts based on the actual road conditions and the driver's intentions.

Is Engine Power Equal to Torque Multiplied by Speed?

Engine power is equal to torque multiplied by speed. Engine power conversion: Power P = π multiplied by torque (M) multiplied by speed (n), where π is approximately 3.14. The concept of power refers to the work done per unit of time. Under a certain power condition, the higher the speed, the lower the torque, and vice versa. The three can be converted into each other. Therefore, the engine's power can be calculated from torque and speed. Automotive engine torque: Torque T = coefficient K multiplied by power P / speed n, where K is often taken as 9549. At each speed, there is a corresponding torque value. Dividing these values by a length can yield force data.

Is it mandatory to drive above 80 km/h on highways?

There is no mandatory requirement for vehicles to drive above 80 km/h on highways. The specific speed should refer to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" and local speed limit signs. Highway regulations stipulate: Article 78: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," highways shall indicate lane driving speeds. The maximum speed shall not exceed 120 km/h, and the minimum speed shall not be lower than 60 km/h. The maximum speed for small passenger cars on highways shall not exceed 120 km/h, other motor vehicles shall not exceed 100 km/h, and motorcycles shall not exceed 80 km/h. Precautions for vehicle traffic accidents: In the event of a traffic accident on a highway, the driver should promptly signal danger to following vehicles, immediately turn on the hazard warning lights, and at night, also turn on the width marker lights and tail lights. The driver and passengers must quickly move to the right shoulder or emergency stopping lane, place a warning sign at least 100 meters behind the accident vehicle, and immediately report to the traffic police or highway monitoring room via emergency phone, briefly describing the following: accident location, time, condition (collision, rollover, or fire, etc.), scale, and casualties. Other personnel should take measures to rescue the injured and protect the scene. If there are injured individuals requiring immediate hospital treatment, they may signal for help from passing vehicles but must not attempt to forcibly stop vehicles or rescue the injured on the driving lane themselves.
