Can High Beam Be Used on Highways?

High beam can be used on highways. Here are some relevant introductions about high beam: 1. Reasons for using high beam on highways: When driving on highways, due to high speed, lack of street lights, and poor visibility, if high beam is not used, it will be impossible to see the road conditions ahead in time, which may lead to traffic accidents. 2. Hazards of improper use of high beam: It can cause visual blind spots for drivers, easily leading to accidents. 3. Measures to deal with improper use of high beam: Adjust the rearview mirror direction, tap the brakes, or install anti-glare rearview mirrors. 4. Reasons why high beam cannot be used at signal-controlled intersections: The intense light of high beam can cause temporary dizziness, so it is not allowed to use high beam when driving in urban areas. When overtaking at night, high beam and low beam should be used alternately to alert the vehicle in front.

Can You Keep Driving with Engine Shaking?

Engine shaking occurs when certain components malfunction, but whether you can continue driving depends on the actual cause of the shaking. Here are the reasons for engine shaking: 1. Engine Misfire: Engine misfire mainly refers to one or more cylinders not functioning properly. Common symptoms include intermittent exhaust flow, severe shaking of the exhaust pipe, and noticeable engine vibration, sometimes accompanied by a sputtering sound. This is often related to ignition coil failure. 2. Worn or Loose Engine Mounts: Engine mounts are rubber blocks placed between the engine and the frame to reduce vibration and cushion the engine's operation while securing it in place. Once these mounts become worn or loose, the engine shaking will become significantly worse. Replacing the mounts can greatly reduce this issue. 3. Carbon Buildup: Carbon buildup is an unavoidable issue in cars, including carbon deposits in cylinders, throttle valves, spark plugs, and intake systems. When excessive carbon accumulates inside the engine, it affects ignition energy, air intake efficiency, and the air-fuel mixture ratio, leading to unstable power output. Both idling and acceleration may exhibit shaking. It is recommended to visit a 4S shop for an engine cleaning service.

Reasons for Increased Fuel Consumption

Generally, it is caused by temperature and lack of engine maintenance. Below are the relevant explanations: 1. Temperature impact: Fluctuations in fuel consumption due to temperature changes are normal. In winter, lower temperatures typically lead to slightly higher fuel consumption, almost comparable to using air conditioning in summer. This is because low temperatures increase heat dissipation from the engine. To maintain a constant operating temperature, the engine burns more gasoline to generate heat, which is wasted as it doesn't contribute to work output, thus increasing fuel consumption unavoidably. Additionally, winter warm-up times are longer, requiring more time and gasoline from cold start until normal water temperature is reached. 2. Prolonged lack of vehicle maintenance: Dirty engine oil and air filters can also increase fuel consumption. Dirty oil leads to poor lubrication, increasing resistance in engine moving parts and requiring more energy to overcome it, thereby raising fuel consumption. A dirty air filter restricts airflow, first requiring more energy for intake and second leading to incomplete combustion as insufficient air results in unburned gasoline being expelled, naturally requiring more fuel for the same distance traveled.

Can Used Cars with China 5 Emission Standard Still Be Registered?

Normally, used cars with China 5 emission standard can be registered. The restriction on China 5 registration mainly applies to new cars, but in the used car market, vehicles with China 5 emission standards are not subject to registration restrictions. Therefore, used cars meeting China 5 emission standards can be registered normally. As for registering used cars from other regions, it depends on the requirements and conditions of the local vehicle management office. It is recommended to verify the situation with the local vehicle management office in advance. Below is relevant information: 1. China 5: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as "China 5 Standard," has emission control levels equivalent to the European Union's Stage 5 emission standard currently in effect. 2. Difference: Compared to the China 4 standard, the new standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on an annual vehicle registration volume of approximately 350,000 in Shanghai, it is estimated that annual nitrogen oxide emissions could be reduced by around 1,000 tons from newly added vehicles.

What are the symptoms of car valve problems?

When car valves have problems, symptoms may include driving vibration, unstable engine operation, difficulty starting, black smoke from the exhaust pipe, increased fuel consumption, and in severe cases, abnormal engine noises, illuminated fault lights indicating misfire faults, and other phenomena. When these symptoms appear, a fault diagnostic tool can be used to determine the specific position of the throttle valve and observe the data stream display. If the throttle opening is found to be too large, it should be cleaned. If the throttle valve's fault is permanent, the entire assembly usually needs to be replaced as it generally cannot be disassembled for repair. Cleaning should be done with moderation, as excessive cleaning can lead to premature failure of the throttle valve, gradually removing the special coating inside the throttle chamber, causing oil sludge buildup and creating a vicious cycle.

What is the difference between double wishbone and double transverse arm?

Double wishbone and double transverse arm have the following differences: 1. Different in nature: Double transverse arm suspension refers to a suspension system with two transverse arms. Double transverse arm suspension can be further divided into equal-length double transverse arm suspension and unequal-length double transverse arm suspension. The equal-length double transverse arm suspension can maintain the kingpin inclination angle unchanged when the wheels move up and down, but it causes significant changes in wheel track, leading to severe tire wear, and is rarely used nowadays. Double wishbone suspension, also known as double A-arm independent suspension, features upper and lower A-shaped wishbones that can precisely position various parameters of the front wheels. When the front wheels turn, both the upper and lower wishbones can absorb the lateral forces on the tires, while the strut only bears the weight of the vehicle body. 2. Different advantages: The advantage of double transverse arm independent suspension is that the shock absorber does not bear lateral loads, and the upper end height is relatively low, which helps reduce the height of the front of the car and improve the vehicle's styling. The advantages of double wishbone suspension are high lateral stiffness, excellent anti-roll performance, good grip performance, and clear road feel. 3. Different disadvantages: The disadvantage of double transverse arm independent suspension is its complex structure and large space occupation. The disadvantage of double wishbone suspension is the complexity in setting the suspension positioning parameters. 4. Different applicability: For unequal-length double transverse arm suspension, by appropriately selecting and optimizing the lengths of the upper and lower transverse arms and through reasonable arrangement, the changes in wheel track and front wheel positioning parameters can be kept within acceptable limits, ensuring good driving stability for the vehicle. Currently, unequal-length double transverse arm suspension is widely used in the front and rear suspensions of sedans, and some sports cars and racing cars also adopt this suspension structure for their rear wheels. Double wishbone suspension is not suitable for the front suspension of small cars. Double wishbone suspension excels in sportiness and is used by supercars such as Ferrari and Maserati.
