What procedures are required for mobile refueling vehicles?

Introduction to the procedures required for mobile refueling vehicles: Must hold the "Wholesale (Retail) Operation License for Refined Oil", "Hazardous Chemicals Operation License", "Road Transport Operation License" and "Business License", and carry on board the vehicle and driver's qualification certificates, refined oil distribution contract, and oil purchase outbound certificate. Additional information: 1. Note 1: Mobile refueling vehicles must also pay attention to avoiding other vehicles while driving on the road. The driving of the vehicle is subject to a dedicated person responsibility system, and others are not allowed to use the refueling vehicle without permission. 2. Note 2: Staff operating refueling vehicles must undergo professional training and pass corresponding assessments before they can start working. In daily work, attention should be paid to checking the specific conditions of the oil pump, valves, oil pipelines, and other parts, and only after confirmation can they be started for use.

Will the tire lose all its air overnight if punctured?

Tire air will not completely leak out overnight if punctured. For tubeless tires with a nail puncture, the air can typically last about a week if the nail is not removed. Since the tire is tubeless, it won't immediately lose air when punctured by a nail. However, over time, the air will gradually escape. When driving on highways, if you discover a nail in your tire, you should immediately drive to the nearest exit for tire repair before continuing. The functions of tires are: 1. Transmit driving force, braking force, and steering force to enable vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging automotive components. Tire maintenance methods include: 1. Regularly check tire pressure; 2. Periodically inspect tires for bulges, cracks, cuts, punctures, or abnormal wear; 3. Remove foreign objects such as stones, metal pieces, or nails from tire treads; 4. Perform wheel alignment or tire balancing.

What are the differences between the 2018 and 2019 Envision models?

The differences between the 2018 and 2019 Envision models lie in their emission standards: the 2018 Envision complies with the China V standard, while some 2019 models meet the China VI standard. The Envision is a strategic model launched by General Motors, classified as a midsize SUV. Its body dimensions are: length 4694mm, width 1839mm, height 1686mm, with a wheelbase of 2750mm, a fuel tank capacity of 66 liters, and a curb weight of 1610kg. The Envision features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 169PS, a maximum power of 124kW, and a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.

Will the Engine Stall When Releasing the Clutch in Subject 3?

No, since the clutch is already in the semi-engaged state (half-clutch state), the engine will not stall. Below is relevant information about the driver's license test: 1. Subjects: The test is conducted in sequence from Subject 1, Subject 2, Subject 3, to Subject 4. In the Subject 3 test items, the new regulations circulating online also place more emphasis on the driver's safety and civilized awareness. 2. Retake: For the driving test, Subjects 2 and 3 can only be taken five times each. If you fail, you will have to pay the tuition fee again. According to the Ministry of Public Security's Order No. 123 and 124, if you fail the fifth scheduled test for Subject 2 and Subject 3 road driving skills, all previously passed subject scores will be invalidated. If you want to obtain a driver's license, you will have to re-register and pay the tuition fee to the driving school.

What is the difference between a four-cylinder and a six-cylinder engine?

The differences between a six-cylinder and a four-cylinder engine are as follows: 1. A six-cylinder engine has six cylinders, while a four-cylinder engine has four cylinders. 2. Different engine displacements: A 2.5-liter engine is typically a four-cylinder, while a 3-liter engine is usually a six-cylinder. 3. Six-cylinder engines have a longer lifespan than four-cylinder engines; four-cylinder engines vibrate more than six-cylinder engines; six-cylinder engines consume more fuel than four-cylinder engines; six-cylinder engines have higher horsepower output than four-cylinder engines; six-cylinder engines have higher torque output than four-cylinder engines; four-cylinder engines are more environmentally friendly than six-cylinder engines; six-cylinder engines are more expensive than four-cylinder engines; six-cylinder engines have higher modification potential than four-cylinder engines; four-cylinder engines have higher maintenance costs than six-cylinder engines; six-cylinder engines have higher usage costs than four-cylinder engines. Here is some related information: 1. Based on displacement, engines are categorized into three-cylinder, four-cylinder, six-cylinder, and eight-cylinder types. 2. Currently, most cars with displacements ranging from 1.3 to 2.3 liters use inline four-cylinder engines, which are characterized by their compact size, simple structure, and easy maintenance. Engines with displacements above 2.5 liters generally use multi-cylinder designs, including inline six-cylinder engines like those in BMWs, and V6 engines arranged at an angle to reduce vibration and noise, such as those in Buick models. 3. Generally, the larger the displacement, the higher the engine's power output. However, some small-displacement cars now use technologies like turbocharging, multi-valve systems, and variable valve timing to increase power. Typically, with the same cylinder diameter, more cylinders mean larger displacement and higher power output. With the same displacement, more cylinders allow for smaller cylinder diameters, enabling higher engine speeds and thus greater power output.

Can You Still Take the Driving Test in Heavy Rain?

You can still take the driving test in heavy rain. Here are some precautions for taking the test in rainy conditions: 1. Brake earlier in the rain: The braking distance on muddy or wet roads can be up to three times longer than on dry roads, so braking is not as responsive as in normal weather. For safety, apply the brakes earlier than usual. Compared to completely wet roads, roads that are not fully soaked are more prone to skidding. 2. Driving through waterlogged sections: When passing through waterlogged areas, observe the driving conditions of other vehicles to ensure you avoid obstacles like deep potholes. When water submerges the exhaust pipe, be cautious of water entering it. To prevent this, shift to a low gear before entering the water and maintain a steady, slightly higher speed to drive straight through. Do not lift off the accelerator after entering the water to avoid water entering the exhaust pipe; avoid shifting gears midway to prevent the drive wheels from losing traction; and maintain a steady, straight drive to reduce resistance.
