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).

What engine does the Geely Boyue have?

The engine of the Geely Boyue is produced by Geely Auto itself, utilizing Volvo's technology, making it a domestically manufactured engine. The engine model of the Geely Boyue is JLE-4G18TDC, a 1.8T version with a maximum power of 135kw/5500rpm and a maximum torque of 285Nm/1500-4000rpm. The 2.0L version has a maximum power of 104kw/6000rpm and a maximum torque of 178Nm/4000-4500rpm. For daily maintenance of the Geely Boyue's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
