What is the maximum speed limit on urban one-way streets?

Motor vehicles driving on roads must not exceed the speed indicated by speed limit signs or markings; on urban roads with two or more motor vehicle lanes in the same direction and without speed limit signs or markings, the maximum speed is 70 kilometers per hour, while on enclosed motor vehicle-only roads and highways, the maximum speed is 80 kilometers per hour. According to regulations, motor vehicles must not exceed the speed indicated by speed limit signs or markings when driving on roads. On roads without speed limit signs or markings, motor vehicles must not exceed the following maximum speeds: 1. Roads without a central dividing line: 30 kilometers per hour for urban roads and 40 kilometers per hour for highways; 2. Roads with only one motor vehicle lane in the same direction: 50 kilometers per hour for urban roads and 70 kilometers per hour for highways.

Is the left side of the car the clutch or the brake?

In most cars, the left side is the clutch. For automatic transmission vehicles, the right side is the accelerator pedal; the middle is the brake pedal; and the left side is the parking brake pedal. For manual transmission vehicles, the right side is the accelerator pedal; the middle is the brake pedal; and the left side is the clutch pedal. 1. Do not press the brake and clutch simultaneously: For safety reasons, if the brake and accelerator were placed on opposite sides, a driver might panic in an emergency and press both pedals at the same time, causing the car to brake and accelerate simultaneously, which poses a significant danger. 2. Function of the clutch: In a car, the clutch pedal is an important device operated by foot. The key to operating the clutch effectively is mastering the engagement point. Disengaging the clutch is relatively simple—just press the clutch pedal quickly and fully without hesitation to prevent partial slipping and accelerated wear.

What is the appropriate tire pressure for the Nissan X-Trail?

The appropriate tire pressure for the Nissan X-Trail is around 2.5 bar. Tire pressure refers to the air pressure inside the tires, which is essentially the 'blood pressure' of a car. The level of tire pressure plays a crucial role in the vehicle's performance and power. It also serves as an indicator of the car's load capacity, as the load a car can carry depends on the tire pressure. Taking the 2021 Nissan X-Trail as an example, its body structure is a 5-door, 5-seat SUV with dimensions of 4675mm in length, 1820mm in width, and 1722mm in height. It has a wheelbase of 2706mm, a front track of 1575mm, a rear track of 1570mm, a fuel tank capacity of 65 liters, and a trunk capacity of 700 liters.

Why is the car display screen still on after the engine is turned off?

The reason why the car display screen is still on after the engine is turned off is: there is a problem with the power supply module, and the relay needs to be checked and repaired in time. At this time, you can use a car diagnostic tool to detect, enter the SMK system to read the data stream. If the data stream ACC and ACC input circuit and battery circuit are all in the ON state when the engine is off, it means that it is currently in a short circuit state. The display screen includes the central control door lock system, central console, and audio control panel. Its functions are: 1. The central lock actuator can be used to execute the driver's instructions to lock or unlock the door; 2. Control the adjustment of memory seats, music system adjustment, entertainment system adjustment, roof camera function, and automatic parking function.

What does the red pavement on urban roads represent?

This is a modified asphalt pavement compared to traditional asphalt pavement. It incorporates new additives such as rubber, resin, polymer, and finely ground rubber powder, which customize and improve the performance of the asphalt. Roads paved with this material exhibit excellent durability, wear resistance, high-temperature resistance (reducing softening), low-temperature resistance (reducing cracking), and good water permeability. Here are the applications of this asphalt: 1. Function: The use of red and colored asphalt serves as a better visual cue for drivers, enhancing road safety. Therefore, red asphalt is increasingly being used in hazardous sections or near schools and hospitals where speed reduction is required, complementing traffic signs to remind drivers to control their speed. 2. Advantages: The new modified asphalt offers strong friction performance, high chemical resistance, low noise, reduced dust, and a more comfortable driving experience, making it highly suitable for highway curves and long tunnels. Particularly in sections prone to water accumulation, modified asphalt can enhance water permeability, preventing hydroplaning accidents caused by high-speed driving.

Is the Mitsubishi 4a92 Engine Really That Outdated and Fuel-Consuming?

The Mitsubishi 4a92 engine is not particularly fuel-consuming; it largely depends on road conditions and vehicle usage. Below is relevant information about the engine: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, among others. 3. External Combustion Engine: An external combustion engine means the fuel burns outside the engine. 4. Internal Combustion Engine: An internal combustion engine, or reciprocating piston engine, differs significantly from external combustion engines in that the fuel burns inside it. There is a wide variety of internal combustion engines, with common gasoline and diesel engines being typical examples.
