Can Suspension Modifications Be Registered?

No, suspension modifications cannot be registered. According to the "Road Traffic Safety Law," altering the suspension system or other structural components without permission from the traffic management department of the public security authority constitutes an illegal modification. In other words, modifying the suspension is considered an illegal alteration of a motor vehicle. Below are relevant details: 1. Scope of Illegal Vehicle Modifications: Per the "Road Traffic Safety Law," illegal modifications include changes to the vehicle's chassis, engine, transmission system, steering system, wheel rims, lights, tire appearance color coating, and external structure. Any alterations to these components that do not match the official data from the vehicle's regulatory authority are considered modifications. 2. Failure to Pass Annual Inspections: According to the "Road Traffic Safety Law," unauthorized modifications to a vehicle's appearance or powertrain are illegal and will result in failure to pass annual inspections. If discovered during inspection, traffic police will require the owner to restore the vehicle to its original condition immediately and may impose fines or revoke the vehicle's license.

Can You Stop in the Emergency Lane When Feeling Drowsy on the Highway?

You cannot stop in the emergency lane on the highway when feeling drowsy. The emergency lane is designated for vehicle emergencies. If you feel extremely tired, you should drive to the next rest stop to take a short break. Remember, unauthorized use of the emergency lane is strictly prohibited and may result in fines and penalty points. Below is relevant information: 1. Definition: The emergency lane on a highway refers to the lane adjacent to the right-side traffic lane, including the hard shoulder, with a width of over 3 meters and an effective length of 30 meters or more, which can accommodate vehicle parking. In emergencies, vehicles are allowed to drive or stop in the emergency lane. 2. Regulations: Article 82 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates that motor vehicles driving on highways shall not engage in the following behaviors: reversing, driving in the opposite direction, making U-turns by crossing the central divider, or stopping within the lane; overtaking on ramps, acceleration lanes, or deceleration lanes; riding or straddling lane dividers or driving on the shoulder; driving or stopping in the emergency lane under non-emergency circumstances; or test driving or learning to drive a motor vehicle.

What are the symptoms of insufficient cylinder pressure while driving?

If the cylinder pressure is insufficient, the following symptoms may occur while driving: lack of power; excessive smoke from the exhaust pipe; and difficulty starting the engine. Insufficient cylinder pressure is usually caused by air leakage in a certain part of the engine or excessive clearance between the piston and the cylinder wall. The effects of insufficient cylinder pressure include: 1. Burning oil: If the clearance between the piston and the cylinder wall is too large, it may also lead to oil burning. Long-term oil burning can damage the vehicle's catalytic converter and accelerate engine wear. 2. Severe carbon buildup: If the cylinder pressure is insufficient, severe carbon deposits may form inside the engine, which can be quite harmful. Excessive carbon deposits on the piston crown can increase the engine's compression ratio, leading to knocking during operation. Engine knocking may cause connecting rod deformation or piston cracking.

Is High-Speed Four-Wheel Drive H or L?

High-speed four-wheel drive is 4H. Here are the relevant details: 1. Definition: 4L stands for low-speed four-wheel drive. The transfer case has a larger gear ratio, which can amplify torque, reduce speed, and increase power. It is suitable for extremely harsh road conditions. 4H stands for high-speed four-wheel drive, where the transfer case has a smaller gear ratio, allowing driving at relatively higher speeds, but with less guaranteed power. It is suitable for general mild off-road conditions. 2. Precautions: It is not recommended to use 4L on icy, muddy, or desert terrains; instead, use 4H. The reason is that on low-traction surfaces during startup, the torque amplified by 4L can be too large, causing the tires to spin and slip instantly, making it difficult to start. Switching between two-wheel drive (2H) and all-wheel drive (4H) can be done while the vehicle is moving, but only within a certain speed range.

What is the normal intake air flow in kg/h?

Intake air flow varies greatly depending on engine design and displacement, and there is no uniform figure. Engine intake air flow is generally controlled by the throttle. Below is an introduction to the throttle: 1. Throttle: The throttle is a controllable valve that regulates air entry into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the throat of the car engine. 2. Types: There are two main types of throttles—traditional cable-operated and electronic. In traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or rod, connecting the accelerator pedal to the throttle linkage plate. Electronic throttles primarily use throttle position sensors to adjust the throttle opening angle based on the engine's power demand, thereby regulating the intake air flow.

Where are the accelerator, clutch, and brake located respectively?

The car clutch is on the left, the brake is in the middle, and the accelerator is on the right. Here are the specific introductions: 1. Clutch: The clutch is the component in the car's transmission system that is directly connected to the engine. Its function is to smoothly engage or temporarily separate the engine's power from the transmission device, reliably transmitting engine torque, so that the driver can perform operations such as starting, stopping, and shifting gears. 2. Brake: The brake is also known as the stopping device. The principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding belt or disc on the machine, which, under external force, generates braking torque. 3. Accelerator: The accelerator, also known as the 'throttle' or 'gas pedal,' refers to the control device that regulates the engine's power (thrust).
