What is the Difference Between S Mode and M Mode?

The differences between S mode and M mode lie in their gear modes and usage environments, as detailed below: Different gear modes: S mode stands for the car's sport mode, which enhances the vehicle's power performance but also increases fuel consumption; M mode represents the manual mode of the car, available only in vehicles with a manual-automatic transmission. When shifted into M mode, the driver can use the gear lever or paddle shifters behind the steering wheel to control upshifts or downshifts. Different usage environments: S mode provides stronger power, making it ideal for overtaking or quick acceleration. M mode, as a manual mode, can be used when driving on steep inclines or declines. S is short for SPORT, meaning sport. When shifted into S mode, the operating logic of the car's engine and transmission changes. In this mode, the transmission can shift freely, but the shift timing is delayed, keeping the engine at high RPMs for a longer duration to deliver instant high torque, thereby increasing the vehicle's power. Other gears may not perform as well. Shifting into S mode increases the engine's RPM, makes the throttle response more sensitive, and causes the transmission to delay shifting. S mode is suitable for overtaking or aggressive driving. M mode: The + and - signs in manual mode have similar functions—+ for upshifting and - for downshifting. The vehicle can be directly switched to manual mode while moving; there's no need to stop to switch. M mode can also be used for quick overtaking and in very specific road conditions, such as when climbing or descending steep slopes. Introduction to other gears in automatic transmission cars: N gear: Neutral means 'neutral,' also known as the neutral gear. It can be engaged when waiting at a traffic light while pressing the brake pedal. For longer waits, it's advisable to engage the handbrake, allowing the foot to rest off the brake pedal. A common misconception is that shifting into N gear while coasting downhill or at high speeds saves fuel. This is a serious mistake—it not only fails to save fuel but can also damage the transmission. D gear: Drive means 'drive,' representing the forward gear in a car. When this gear is engaged, pressing the accelerator allows the vehicle to move. In this gear, the transmission automatically shifts based on speed and throttle conditions. At traffic lights, D gear can be engaged while pressing the brake. For short waits, this is fine, but prolonged use can raise transmission fluid temperature and degrade the fluid. L gear: Low means 'low speed,' representing the low-speed forward gear in a car. When engaged, the transmission operates only in low gear (equivalent to first gear in a manual transmission) and does not shift automatically based on speed changes. This gear is typically used when climbing or descending slopes. In low gear, the drive wheels output higher torque, providing sufficient power to climb steep inclines. Prolonged braking can overheat the brake pads, reducing braking effectiveness, which is dangerous on long or steep descents. Engaging L gear uses the engine's low RPM to restrain the vehicle's movement, eliminating the need for constant braking.

How to Obtain a Class E Driver's License?

You need to bring your original ID card to a local driving school to register. A Class E motor vehicle driver's license allows you to drive a regular two-wheeled motorcycle. During the exam, you must use a motorcycle with an engine displacement exceeding 50ML and a speed capability of over 50 kilometers per hour. Below is more relevant information: 1. Obtaining a Class E driver's license: Register at a local driving school. After successful registration, study theoretical and practical driving knowledge. Passing the exam determines whether you can receive the driver's license. A driver's license is a mandatory document for motor vehicle drivers, legally recognized. While using it, you must comply with relevant regulations; otherwise, you may face fines, demerit points, or revocation. 2. Information on the driver's license: Details include the driver's personal information, gender, name, nationality, date of birth, address, ID number, and photo. Other details include the initial issuance date, the code for permitted vehicle types, the license's effective start date, its validity period, the license file number, and the issuing authority's seal.

Is It Normal for the Car to Pull to One Side When Not Holding the Steering Wheel?

It is not normal for the car to pull to one side when not holding the steering wheel. The reasons for the car pulling to one side when the steering wheel is not moved include unbalanced tire pressure, unbalanced wheel alignment, and unbalanced braking system. Unbalanced tire pressure: Uneven tire pressure on both sides of the vehicle can directly cause the car to pull to one side. When the tire pressure is uneven, the contact area with the ground differs. On normal road surfaces, tires with lower pressure have greater friction, causing the car to pull toward the side with underinflated tires. If you notice the car pulling to one side, it is recommended to visit a repair shop to check whether the tire pressure on both sides is normal. Changes in wheel alignment data can alter the mechanical angles between the wheels and the chassis, especially for vehicles frequently driven on bumpy roads or over curbs. The wheel alignment parameters are more prone to change in such cases, making the car particularly susceptible to pulling to one side. Therefore, it is advisable to regularly visit an auto repair shop for wheel alignment, especially for vehicles frequently driven on uneven roads. Braking system issues: If you notice the car pulling to one side during braking, it is important to inspect the system promptly. The issue could be with the front wheel brake calipers, preventing the brake pads from returning to their normal positions. This is equivalent to one front wheel being in a slight braking state continuously, causing the car to pull to one side. Pay attention to whether the wear on the brake calipers and the brake pads on both sides is even, and visit a repair shop for inspection as soon as possible.

Why has China's oil price been continuously rising?

The reasons for the rise in China's oil prices are as follows: 1. Long-term turmoil in the Middle East: A large number of oil fields have been forced to reduce production or shut down, leading to insufficient crude oil supply, which directly causes fluctuations in international crude oil prices. Additionally, oil prices have already exceeded $60 per barrel and show a continuous upward trend. International oil prices are manipulated by the United States, and China does not have pricing power. On the contrary, China's dependence on oil is increasing. 2. High taxation on oil: There are value-added taxes, consumption taxes, urban construction taxes, etc. On average, half of the price of a barrel of oil goes to taxes. The domestic demand for crude oil is high, and the profitability of major domestic refineries is still insufficient compared to developed countries. The increase in refining costs naturally leads to higher domestic oil prices. 3. Low oil prices would severely impact the new energy industry: For example, new energy vehicles are inherently more expensive than conventional vehicles. If oil prices were to drop, new energy vehicles would lose their market value. Given China's large population, the use of low oil prices could also lead to waste.

What Causes Low Low Pressure and High High Pressure in Car Air Conditioning?

The reason for low low pressure and high high pressure in the air conditioning system is poor circulation within the system. Key areas to inspect include: Capillary tube (or expansion valve) blockage (e.g., due to dirt or ice clogging). Clogged dryer filter. Kinked or pinched connection pipes causing restricted flow. Throttle valve not fully open. Four-way valve not properly aligned. Dirty or clogged condenser radiator tubes. Below is additional relevant information: Notes: 1. Measure the high and low pressure of the air conditioning system while the engine is idling. 2. The normal high pressure for car air conditioning should be 1.3-1.7MPa (13-17kg/cm2 or Lbf/in2); normal low pressure should be between 0.1-0.25MPa (1-2.5kg/cm2 or 15-35Lbf/in2). If the low pressure is higher or lower than this range, it indicates improper adjustment of the expansion valve. Compressor issues are not included in this category. When the engine throttle is increased, the measured low pressure should decrease with engine speed—the faster the speed, the greater (and quicker) the pressure drop. This indicates good compressor performance; otherwise, it suggests a compressor malfunction. 3. It's important to note that car air conditioning pressure is significantly influenced by ambient temperature (the working environment of the condenser).
