What to Pay Attention to in High Temperatures?

When driving in high temperatures, it is important to carefully check for any aging or exposed wiring and repair it promptly to avoid unexpected incidents such as vehicle self-ignition. Be cautious about items placed inside the car; flammable and explosive items like lighters, perfumes, and spray cans should not be left in the car for extended periods to prevent accidents caused by excessive interior temperatures. More details are as follows: 1. During prolonged summer driving in high temperatures, regularly check tire pressure. The pressure should not be too high; it can be slightly lower, but not too low, as this may cause the steel wires inside the tires to deform, leading to potential hazards. 2. When wearing sunglasses while driving in high temperatures, avoid overly dark lenses. Opt for lighter-colored sunglasses to prevent visual errors. 3. Some drivers prefer wearing sandals when driving in summer heat, but this can be dangerous as sandals may cause the feet to slip, leading to reduced pedal control and abnormal braking, increasing the risk of accidents. 4. High temperatures can easily cause drowsiness, especially during midday in summer when people tend to feel particularly sleepy. It is crucial to avoid fatigue driving. If you feel mentally foggy while driving, find a safe spot to rest briefly until you regain alertness before continuing.

What is the actual fuel consumption of the Haval Big Dog 2.0?

Haval Big Dog 2.0t has three models on sale. The two-wheel-drive Zhonghua Hunting Dog version is equipped with a 211-horsepower engine, with an NEDC fuel consumption of 7.2L per 100 kilometers. The four-wheel-drive Xiaotian Dog version and the four-wheel-drive Zhonghua Pastoral Dog version are also equipped with a 211-horsepower engine, with an NEDC fuel consumption of 8L per 100 kilometers in fuel mode. The distance that the Haval Big Dog can travel on a full tank of fuel is as follows: The fuel tank of the Haval Big Dog 2.0t is 61L, and the distance it can travel on a full tank is 61/7.2*100=847km. The fuel tanks of the four-wheel-drive Xiaotian Dog version and the four-wheel-drive Zhonghua Pastoral Dog version are 60L, and the distance they can travel on a full tank is 60/8*100=750km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when encountering a red light, can increase fuel consumption. The car itself: Cars with larger displacements consume more fuel than those with smaller displacements because larger displacements generally mean greater power, requiring more gasoline to burn and perform work. Cars with greater weight also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Environmental temperature: Low environmental temperatures result in lower engine block temperatures. During cold starts, the injected gasoline is less likely to atomize, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, low temperatures cause the engine computer to control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Should a Car with a Blown Head Gasket Be Repaired or Sold?

A car with a blown head gasket can be repaired. With the continuous advancement in repair techniques and standards, if the engine receives proper and correct repairs after a blown head gasket, it will not significantly affect the car's usage. Here is some relevant information: 1. Main causes of a blown head gasket: (1) The engine operates at high temperatures for extended periods without adequate cooling, leading to deformation of the engine block due to overheating. (2) During engine assembly, the bolts connecting the cylinder head to the engine block were not tightened to standard specifications. Excessive pressure can then damage the head gasket. (3) Uneven surfaces between the cylinder head and engine block cause uneven pressure distribution on the head gasket, resulting in damage from high-pressure gas. (4) Neglecting regular maintenance, such as failing to check coolant and engine oil levels. Insufficient lubrication and coolant can lead to engine overheating, increased wear, and deformation of the engine block. (5) Long-term aggressive driving causes fluctuating pressure levels within the engine block. 2. Common symptoms of a blown head gasket: (1) Overheating coolant temperature (normal operating temperature is around 90°C). (2) Severe engine shaking accompanied by unusual noises. (3) Rapid consumption of coolant. (4) Engine oil turning into a cloudy, milky yellow color.

What Does the Structure of a Car Door Lock Include?

The structure of a car door lock includes the following: 1. Large Bracket: The large bracket is the main component that drives the movement of the large latch. It serves as the main body for installing the large latch. The head of the large bracket is the riveting area for the large latch. The rectangular hole in the middle can engage with the hook on the pull plate. The outer step is the slot for the brake plate to snap into, while the lower part can fit into the slider clamp, facilitating the pulling of the slider. Additionally, when the large bracket is pushed inward, it is not obstructed by the slider clamp. 2. Small Bracket: The small bracket is the main body for installing the small latch and serves as the primary component controlling the self-locking of the large latch. The head of the small bracket is used to assemble the small latch, and the protruding triangular part in the middle is used to push the brake plate, thereby eliminating the self-locking effect of the brake plate on the large bracket. 3. Pull Plate: The pull plate plays a role in positioning and releasing the self-lock when the large latch is pulled inward. The hook at the top of the pull plate can be inserted into the rectangular hole in the middle of the large bracket, allowing it to pull the large bracket inward together or slide within the rectangular hole when the large bracket is pushed inward. The side extensions of the pull plate can move the brake plate to release its self-locking effect on the large bracket. The small circle in the middle of the pull plate is used for its own positioning, while the protrusions on both sides enable the large bracket to move within the formed groove. The lower clamp can fit into the slider clamp, allowing movement under the control of the slider.

How many chances are there for the B2 driver's license probationary period exam?

The number of attempts is unlimited; candidates can retake the exam until they pass. However, if they fail to participate in the required study, education, and exams as stipulated, the review will not be approved. Within thirty days after the end of the B2 driver's probationary period, candidates must take an exam covering road traffic safety laws and regulations, civilized driving practices, emergency handling, and other related knowledge, and they must also undergo at least half an hour of traffic accident case warning education. Here are the relevant details: 1. Continuous Examination: The "Opinions" propose that in the future, venue driving and road driving skill exams will gradually adopt a one-time appointment system, allowing continuous examination to reduce the number of trips candidates need to make. The nighttime exam method for small vehicles will be adjusted, allowing simulated nighttime lighting exams to be conducted during the day. After passing all subjects and completing the necessary procedures, the motor vehicle driver's license should be issued to the candidate on the same day. This way, obtaining a driver's license will no longer require multiple trips as it does now. 2. Passing Standards: (1) Traffic laws and related knowledge (Subject 1) — Written test, scored out of 100, with 90 or above considered passing (including 90). (2) Venue driving (Subject 2) — On-site, actual vehicle. Only pass or fail. The five mandatory tests, conducted in sequence, include reversing into a parking space, parallel parking, S-curve driving, right-angle turns, and hill starts and stops. Scored out of 100, with 80 or above considered passing (including 80). For large buses, medium buses, and large trucks, 90 or above is required (including 90). (3) Road driving (Subject 3) — Highway or simulated venue, actual vehicle. Scored out of 100, with 90 or above considered passing (including 90). (4) Safe and civilized driving knowledge (Subject 4) — Written test, scored out of 100, with 90 or above considered passing (including 90).
