What should be paid attention to when reversing at night?

Precautions for reversing at night: 1. First carefully observe the parking position and mentally simulate an exit route map; 2. The illumination of the reversing lights is limited, make full use of the brightness of the brake lights; 3. All interior lights should be turned off; 4. Frequently get out of the car to observe; 5. When someone is directing, pay special attention to their standing position. Tips for reversing into a parking space: 1. Adjust the direction of the vehicle to align the rear with the parking space; 2. When the left rearview mirror can see the corner of the vehicle on the left side of the parking space, you can start reversing; 3. While reversing, observe the left and right rearview mirrors, paying attention to the distance between the rear wheels and the adjacent vehicles to avoid scratches; 4. When the rear wheels of the vehicle have entered the parking space, observe both sides through the rearview mirrors; 5. Correct the direction appropriately to straighten the vehicle into the space as much as possible.

How to Use ETC After Successful Activation?

Usage method after successful ETC activation: 1. You need to recharge the ETC card and attach the small device to the front windshield; 2. When entering the ETC lane at highway toll stations, maintain a speed of approximately 20 kilometers per hour, and the toll will be automatically deducted. ETC is an electronic toll collection system that doesn't require stopping. The ETC dedicated lane is designed for vehicles equipped with ETC onboard units, utilizing electronic toll collection methods. The ETC non-stop toll system achieves the purpose of paying bridge and road tolls without stopping by establishing microwave-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, using computer networking technology for backend settlement processing with banks.

What does driving on the shoulder mean?

Driving on the shoulder refers to a vehicle traveling on the far-right lane of the road, which is the edge section adjacent to the roadside. On both regular roads and highways, driving on the shoulder is prohibited due to its high risk, especially on highways where the far-right lane is designated as an emergency lane. The emergency lane is not permitted for regular vehicle traffic. Under normal circumstances, the shoulder is not allowed for driving. However, in emergencies (including vehicle breakdowns), vehicles may briefly stop on the shoulder. Special vehicles such as police cars, ambulances, and tow trucks performing official duties have the right of way, and other vehicles may only pass under police direction. Therefore, the shoulder can also be referred to as an emergency stopping lane or emergency driving lane. The emergency lane is primarily designated for situations involving traffic accidents where police cars, ambulances, or fire trucks need immediate access to the scene for rescue operations. During normal driving, it is illegal to occupy the emergency lane, and prolonged driving or stopping in this lane is strictly prohibited. Emergency lanes are typically marked on both sides of urban ring roads, expressways, and highways.

What is the reason why Wuling Zhiguang cannot accelerate when the engine is hot?

Check the fuel pressure. Check whether the intake manifold (including the air filter) is unobstructed. The following is a related introduction to Wuling Motors: 1. Introduction: Wuling is the registered trademark and brand of Liuzhou Wuling Automobile Co., Ltd. This logo has been fully authorized for use by SAIC-GM-Wuling. 2. Appearance: Wuling Hongguang adopts the currently very popular double U front face design and a three-dimensional vertical waterfall-style chrome-plated air intake grille, which not only makes the front of the car look more fashionable and dynamic but also inherits some characteristics of the General Motors series. The eye-catching eagle-eye crystal diamond headlights and feather-shaped crystal diamond front fog lights further enhance the vehicle's sense of grade. The two powerful lines on the engine hood give a strong sense of power visually.

What Causes Engine Oil to Leak into the Radiator?

Causes of engine oil in the car radiator: 1. Blown head gasket: After the head gasket is damaged, the oil passage and coolant passage become connected. Since the oil pressure is higher than the coolant pressure, the oil enters the coolant passage and then the radiator. Observe air bubbles escaping from the surface of the radiator coolant. After stopping the engine, the coolant will flow into the oil passage and then into the oil pan. 2. Cracked cylinder liner: Due to the high fuel pressure in the cylinder, oil and diesel are "squeezed" into the coolant through cracks in the cylinder liner under high pressure. Observe the surface of the coolant for intense movement of air bubbles. 3. Faulty oil cooler: During assembly or manufacturing of the oil cooler, cracks in the cooling tubes, poor welding, or freezing and cracking of the cooling tubes due to not draining the coolant properly in winter can cause oil to enter the coolant. If you observe the surface of the radiator coolant, it is generally calm.

What Causes the RPM of a Single-Cylinder Diesel Engine to Fluctuate?

Air entering the fuel line, leading to poor fuel supply, prolonged use of the fuel injection system, and aging of the fuel injection system, among others. Common causes of unstable diesel idle speed are as follows: 1. Significant air leakage: During idle, excessive cylinder air leakage results in substantial energy loss within the cylinder, leading to lower compression temperatures and pressures, poor fuel atomization, and significant combustion fluctuations. 2. Insufficient fuel supply: At idle, the fuel supply is minimal, and slight variations in fuel supply to each cylinder can cause differences in their operating states. This uneven fuel distribution during idle leads to the diesel engine's idle hunting phenomenon. 3. Low nozzle precision: The direct injection in diesel engines has driven fuel injection pressures to higher levels, especially with the adoption of multi-hole injectors. This makes the nozzle less precise when delivering small fuel quantities, prone to fluctuations. Unstable fuel supply in diesel engines is a major cause of idle instability.
