Does the driver's license gain an extra point after learning and deduction?

After learning and deduction, the driver's license does not gain an extra point. After learning and deduction, you can continue to accumulate demerit points. It only reduces the existing demerit points on the driver's license and does not affect its usage. For example, if you were penalized with 6 points for a violation, passing the learning and deduction exam would clear those 6 points, allowing you to start fresh. On the surface, learning and deduction seems to grant the driver's license more behavioral points, but its primary purpose is to encourage penalized drivers to participate in learning, thereby promoting legal awareness. More relevant information is as follows: Note 1: The number of points deducted after learning and deduction depends on how many points the driver had before participating in the learning and deduction program, as well as how many points were reduced. However, the total accumulated demerit points cannot exceed 11. First, it's important to clarify that, regardless of participation in learning and deduction, a driver's license only has 12 points. It can only reduce existing demerit points on the license, not increase the total to 18 points. Note 2: Simply put, the cleared points are not counted in the accumulated demerit points. For example, if you were penalized with 9 points and reduced 6 points through learning and deduction, then in this scoring cycle, you would effectively have only 3 points deducted. Within this scoring cycle, you could still accumulate up to 8 more demerit points.

What Are the Reasons for the Air Conditioning Not Cooling in New Energy Vehicles?

The reasons for the air conditioning not cooling in new energy vehicles could be insufficient or too little refrigerant, or minor refrigerant leakage. Additionally, excessive refrigerant can also cause the air conditioning to not cool properly. This is because the proportion of refrigerant in the air conditioning system must meet specific requirements. If the proportion is too high, it can affect heat dissipation. Similarly, if too much cooling oil is added during maintenance, the heat dissipation of the cooling system may decrease. 1. Insufficient or too little refrigerant solution: This can be observed from the sight glass on top of the dryer. During normal operation of the air conditioning, if there are continuous, slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means the refrigerant is severely insufficient. If the refrigerant is insufficient or too little, the solution is to add refrigerant. However, note that if adding from the low-pressure side, do not invert the refrigerant bottle; if adding from the high-pressure side, do not start the engine. 2. Excessive refrigerant solution: Observe from the sight glass on top of the dryer. If no bubbles are visible in the sight glass during the operation of the car air conditioning, and no bubbles appear after the compressor stops, it definitely indicates excessive refrigerant. If the pressurized cooling oil is excessive, relatively turbid bubbles can be seen in the sight glass during normal operation of the air conditioning system. Of course, if the refrigerant is indeed excessive, some can be slowly released from the maintenance port on the low-pressure side of the air conditioning system.

What is the standard tire pressure for the Envision 1.5T?

The standard tire pressure for the Envision 1.5T is approximately 2.3-2.5 bar. According to the international standard GBT2978-2008, the tire pressure requirements for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to abnormal heat generation due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, leading to damage and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire deformation, causing sidewall cracks and flexing movements, leading to overheating, rubber aging, cord fatigue, and breakage, as well as increased ground contact area, accelerating shoulder wear.

Can Air Filters Be Reused?

They can be reused, but replacement is recommended. Using compressed air to blow or washing with water can remove thick accumulated dust, but it's difficult to clean the dust trapped inside the paper. The function of an air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder, preventing floating dust from being sucked into the engine, which accelerates the wear of the piston group and cylinder. According to the car's maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter element varies depending on the intake form and engine structure. It is usually located in the air cleaner on the engine intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. Using an overly dirty air cleaner in a car while driving can cause insufficient engine intake, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air cleaner clean. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder to reduce early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must first pass through the fine filtration of the air cleaner. An overly dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if you find little dust and minor blockage, you can use high-pressure air to blow it clean from the inside out and continue using it. An overly dirty air cleaner should be replaced promptly.

What are the reasons for the Ford Focus engine warning light to come on?

There are mainly 7 reasons for the engine warning light to come on: Sensor failure: The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to come on. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the engine's air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine warning light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, high oil consumption, reduced power, metal noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the car's intake, it may cause engine pipeline blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust faults can also cause the engine warning light to come on. The rear oxygen sensor, three-way catalytic converter, exhaust camshaft, and bearing failures are all causes of exhaust problems, with the three-way catalytic converter being the most common. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or engine fuel system faults can easily cause three-way catalytic converter failure. Anti-theft system failure: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can also cause the engine to malfunction and the warning light to come on. If the engine warning light comes on, you can follow these steps: First, check if the engine is running normally, whether there is shaking, black smoke, etc. If so, try not to start the engine again. Especially note that if the red light is on, do not start the engine. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without pressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe if the warning light on the dashboard goes off. If the warning light does not go off, please visit a service station as soon as possible to find out the cause. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs.
