Automobile steering system is a power steering system, the so-called power steering, that is, with the help of external force, so that the driver can complete the steering with less force. The symptoms of power steering include: heavy steering, steering noise, steering system oil leakage, poor steering wheel return ability, etc. Fault causes and solutions for heavy steering: The power steering system contains a large amount of air, resulting in abnormal steering. Foreign matter in the steering hydraulic pipeline causes the steering pump flow control valve to stick. Check the steering gear, steering pump control valve, oil cup filter, steering oil, and clean the entire power steering system. Looseness in the connection parts of the power steering system causes steering fluid leakage. Check all connection parts of the oil pipe and tighten all connection bolts. Excessive wear of the steering gear piston cylinder, poor sealing of the oil seal, sticking or damage of the control valve. Replace the oil pipe, power steering pump or power steering gear. Fault causes and solutions for steering noise: Overload operation of the steering system causes excessive wear of the stator and rotor inside the steering pump, resulting in irregular movement of the oil in the pump and noise. Clean the entire steering system. Looseness in the installation of the steering gear and steering pump on the bracket, internal wear of the steering gear and improper adjustment of the gear and rack. Adjust the gear and rack clearance of the steering gear according to the regulations. Fault causes and solutions for steering system oil leakage: The steering pump will not leak oil without damage. However, it is still necessary to check the connectors and connection parts in the power system and steering system to see if there is any leakage. Check the oil pipe, oil cup, steering gear and power steering pump in the steering system.

What Lights Should You Use in Foggy Weather?

Introduction to using car lights in foggy weather: 1. When driving in fog, you should turn on both front and rear fog lights. If the fog is extremely heavy, you can also turn on the hazard lights. The main purpose of turning on fog lights and hazard lights is to alert other drivers and avoid rear-end collisions or side-swipe accidents. 2. If your vehicle doesn't have fog lights, turn on the width marker lights and hazard lights to attract other drivers' attention. 3. Do not use high beams in foggy conditions. High beams will create a blinding white wall ahead, making visibility even worse. Therefore, it's recommended that drivers use high beams only as signal lights to alert oncoming vehicles, but the flashing duration should be extremely brief to avoid impairing other drivers' vision and causing accidents.

ETC Electronic Tag Failure?

ETC displaying 'tag failure' indicates that the ETC electronic tag is not activated. You need to bring the ETC device to an ETC service center or ETC service outlet for inspection. If the failure is not caused by human factors, a simple secondary activation of the ETC will restore its functionality. How ETC Works: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, ETC utilizes computer networking technology to process background settlements with banks. This enables vehicles to pass through highway or bridge toll stations without stopping to pay fees. Where to Install ETC: For small vehicles such as cars and minivans, the ETC card and OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part.

How to Judge the Distance Between Cars When Driving?

A following distance of about 2 meters is generally appropriate. Being too close can easily lead to rear-end collisions, while being too far may allow other vehicles to cut in. Normally, drivers can judge the distance by observing the position of the rear bumper and tires of the preceding vehicle from the outline of their own car's front: How to judge the distance between cars on the left, right, front, and rear To determine the position of the left wheel, we need to know where the left wheel will pass to avoid running over solid lines or obstacles like potholes and rocks on the road. When our line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will pass over that object. For example, in the following illustration, if the wiper node aligns with the centerline on the ground, the tire will run over the centerline.

What does 3T on tires mean?

The 3T marking on tires refers to the Treadwear Index, Traction Index, and Temperature Index. The Treadwear Index indicates the tire's wear resistance—the higher the number, the more wear-resistant the tire is, but the harder the rubber becomes, resulting in reduced comfort. Conversely, a lower number means less wear resistance, softer rubber, and better comfort. Below are the specific details of the 3T indicators: 1. TREADWEAR (Wear Resistance Index). The higher the number following this, the more wear-resistant the tire is. For typical family sedans, the number is usually above 300, indicating relatively high wear resistance. Performance tires with superior grip, however, often have numbers below 200. 2. TRACTION (Traction Ability). The Traction Index measures the tire's grip performance on wet surfaces, categorized into four grades: AA, A, B, and C. 3. TEMPERATURE (Temperature Index). The Temperature Index grade reflects the tire's heat dissipation capability.

Which is More Fuel-Efficient: Naturally Aspirated or Turbocharged?

Naturally aspirated engines are generally more fuel-efficient than turbocharged engines. Typically, the fuel consumption of a 1.8T turbocharged engine is equivalent to that of a naturally aspirated 2.0-2.4L model. The main reason is that turbocharging only increases pressure within the same cylinder volume to achieve better power and torque performance. With increased air pressure, gasoline consumption cannot be too low. Additional information: 1. A turbocharged engine refers to an engine equipped with a turbocharger. 2. A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then compresses the air delivered from the air filter pipe, pressurizing it before it enters the cylinder.
