What is the Difference Between Gear Oil and Engine Oil?

Gear oil and engine oil differ in their working environments and primary focuses. Below are the key differences between gear oil and engine oil: 1. Different working environments: Gear oil is mainly used in manual transmissions, reducers, and differentials, while engine oil is primarily used in car engines. Since gear teeth engage in direct contact, gear oil requires extremely high viscosity to form an oil film at the gear engagement points. In contrast, engine lubrication involves surface contact and does not experience the extreme pressure generated by gear meshing, so its viscosity requirements are relatively lower. 2. Different focuses: Gear oil emphasizes protecting gears under high temperatures, while engine oil prioritizes low-temperature fluidity. Additionally, gear oil is strongly alkaline, whereas engine oil is weakly alkaline.

How to Start the Car with a Remote Key?

To start the car with a remote key, the method is: When you are within 50 meters of the car, press the start button on the remote key to start the vehicle. In simple terms, the working principle is as follows: First, the key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the action of unlocking/locking. Its greatest advantage is that, regardless of day or night, you can conveniently unlock (open) and lock (close) the car from a distance without needing to locate the keyhole. Here are some maintenance precautions for the remote key: Replace the battery promptly: If the key runs out of power, it is recommended to replace the battery promptly; otherwise, it may affect normal use. Avoid repeated remote operations from a distance: During regular use, try to avoid remote operations from a distance or repeated remote operations, as this can accelerate battery consumption. Keep it dry: When not using the remote key, store it in a dry place. Avoid water exposure: When using the remote key, avoid contact with water, as the outer shell of the car remote key is not waterproof. If water enters the key, it can cause the chip to burn out, rendering the key unusable.

What are the benefits of using high-octane gasoline?

Using high-octane gasoline can increase power for high-compression ratio engines. Here is an introduction to the advantages and disadvantages of using high-octane gasoline in cars: 1. Disadvantages of using high-octane gasoline in low-compression ratio engines: Since the cylinder pressure does not reach a certain value, the high-octane gasoline is not sufficiently compressed to reach the flammable point, resulting in incomplete combustion. This means the engine's power cannot be fully utilized, leading to wasted fuel and the potential for engine carbon deposits, which may not be worth the trade-off. 2. Advantages of using high-octane gasoline in high-compression ratio engines: In addition to using the appropriate gasoline for the vehicle, high-compression ratio engines can also use relatively higher-grade gasoline. Due to the higher octane rating, the high-compression ratio engine can burn the fuel more completely, which helps provide more power to the car.

What does a capital A in a circle on a car represent?

This is the on/off switch for the vehicle's auto start-stop function. Below is a related introduction to the engine auto start-stop function: 1. Brief description: The engine auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Its English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a set of controls for engine start and stop. 2. Auto start-stop principle: The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this time, the Start/Stop system automatically detects: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero.

What Do the Numbers on Motor Oil Mean?

The numbers on motor oil represent the following meanings: 1. Winter: Winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 2. Summer: Summer oil grades are: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. 3. All-season: All-season oil grades are: 5W/20, 5W/30, 5W/40, 5W/50, 10W/20, 10W/30, 10W/40, 10W/50, 15W/20, 15W/30, 15W/40, 15W/50, 20W/20, 20W/30, 20W/40, 20W/50. The smaller the number representing the winter part, and the larger the number representing the summer part, the higher the viscosity and the wider the applicable temperature range.

Does driving resistance increase or decrease in rainy weather?

Driving resistance decreases in rainy weather. The main factors affecting safe driving on rainy days include the following aspects: 1. Impaired visibility. 2. Slippery road surfaces. 3. Reduced traction. 4. Decreased friction. Here are some additional details: 1. If a heavy rain has just stopped and the road has been dried by the sun, this provides the best friction performance. 2. During rainy weather, impaired visibility and slippery road surfaces cause the wheel traction to decrease sharply as speed increases, making the wheels prone to skidding. At high speeds, vehicles are also susceptible to hydroplaning, so it is essential to control the speed appropriately.
