What RPM Should a Manual Transmission Car Maintain?

What is the difference between automatic transmission D and S modes?

The differences between automatic transmission D mode and S mode are: 1. Different automatic shift control logic: D mode is comfort and economy oriented; S mode is performance oriented. 2. Different response speeds: When shifted into S mode, if you suddenly press the accelerator while driving, S mode will respond quickly; D mode will wait slightly until it confirms the driver's intention for rapid acceleration before upshifting. 3. Different fuel consumption: When in S mode, the fuel injection volume is greater at high RPM, which will inevitably increase the car's fuel consumption; in D mode, the car runs smoothly with less fuel consumption. Additional information: Automatic transmission means the driver doesn't need to shift gears manually - the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions.

Should You Press the Clutch or Brake First When Turning?

You must press the brake first to reduce speed, while pressing the clutch ensures the car doesn't stall. For sharp turns, if the car shakes while braking, downshifting is necessary. Specific situations require specific operations—some intersections have gentle turns where third or fourth gear may suffice. Below are precautions for turning a car: 1. Adapt to the road: When turning, adjust the steering wheel according to the road's curvature and coordinate with driving speed, ensuring appropriate steering angle, timing, and timely correction. Never remove both hands from the steering wheel to avoid dangerous deviations. 2. Control intensity: Reduce speed when turning and avoid sudden steering to prevent excessive centrifugal force causing skidding. If the car skids, immediately release the accelerator, steer toward the side of the skid, and only resume normal steering after the car straightens its course.

What are the differences between the BMW 520 and 525?

Here are the differences between the BMW 520 and 525: 1. Transmission: The BMW 520Li is equipped with a manual-automatic transmission with a maximum power of 177 horsepower and a peak torque of 230 Nm. It has 4 cylinders, 4 valves per cylinder, and a compression ratio of 12. The BMW 525Li is equipped with a 6-speed manual-automatic transmission with a maximum power of 160 horsepower and a peak torque of 250 Nm; it has 6 cylinders, 4 valves per cylinder, and a compression ratio of 11. 2. Power parameters: The new 525Li's power parameters are basically the same as the previous 520Li, still featuring a 184 horsepower 2.0T engine, but with a different number and name. German brands, especially German luxury car brands, have always had their own logic when it comes to model number naming.

How Many Points Can Be Deducted from a Probationary Driver's License?

During the probationary period, a driver's license can have a maximum of 1-11 points deducted. A probationary license is subject to point deductions, similar to a regular driver's license, with a total penalty value of 12 points. However, for a probationary license, the maximum points that can be deducted range from 1 to 11. If all 12 points are deducted, the probationary driving qualification for the permitted vehicle type will be revoked. In such cases, the driver must reapply for a driver's license and pass all subject tests. Additional Information: Below are methods for new drivers to avoid point deductions: 1. Avoid speeding: It is recommended to use in-car navigation or a safe driving system for speed monitoring and to strictly avoid speeding. 2. Familiarize yourself with road traffic safety laws: Understand relevant regulations and use vehicle lights properly, as failure to comply with light usage rules may result in fines and point deductions.

How to Add Car Refrigerant?

Car air conditioning refrigerant, commonly known as car refrigerant, is mainly divided into two types in vehicles: environmentally friendly 134a and non-environmentally friendly R12. The steps to add car refrigerant are as follows: 1. After vacuuming the system, close the high and low pressure manual valves on the manifold gauge. 2. Connect one end of the middle hose to the refrigerant tank injection valve fitting: open the refrigerant tank valve, then loosen the nut at one end of the manifold gauge hose to allow gas to escape for a few minutes, then tighten the nut. 3. Fully open the high-pressure side manual valve and invert the refrigerant tank. 4. Inject the specified amount of liquid refrigerant from the high-pressure side: close the refrigerant tank injection valve and the high-pressure manual valve on the manifold gauge, then remove the gauge. When adding refrigerant to the system from the high-pressure side, ensure the engine is not running and do not open the low-pressure manual valve on the manifold gauge to prevent hydraulic shock.

What does it mean to be exempt from appointment within 9 days for Subject 4?

In the driving test, there is no Subject 4. The safety and civilization knowledge test of Subject 4 is just an extension of Subject 3, but it is commonly referred to as Subject 4. Therefore, after completing Subject 3, there is no need to wait for 10 days or be exempt from appointment within 9 days. As long as the required learning hours are completed, you can schedule Subject 4 at any time. The relevant introduction to Subject 4 is as follows: Introduction 1: Subject 4 is also known as the theoretical test of Subject 4 or the driver's theoretical test, which is part of the assessment for the motor vehicle driver's license. Introduction 2: The original test consisted of the theoretical test of Subject 1, the stake test of Subject 2, the electronic subject test, and the road test of Subject 3. According to the Ministry of Public Security's Order No. 123, another theoretical test is required after the road test. Since this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test.
