What is the recommended speed control for a new car?

Why does the subject three reservation change from 'under review' to 'under application'?

Acceptance is successful, so it shows as under application. The content of the motor vehicle driver's license examination includes the following four types: 1. Subject one: Road traffic, traffic signals, traffic safety violations and accident handling, regulations on the application and use of motor vehicle driver's licenses, motor vehicle registration, and other road traffic safety laws, regulations, and rules; 2. Subject two: Testing the ability to reverse into a parking space, the mastery of motor vehicle driving skills, and the ability to judge the spatial position of the motor vehicle; 3. Subject three: The situation of driving a motor vehicle on the road to complete the test items, compliance with traffic laws and regulations, and the comprehensive control of the motor vehicle; the correct use of lights, horns, seat belts and other devices; the ability to correctly observe and judge road traffic conditions; 4. Subject four: Separating the knowledge about safe and civilized driving requirements from the original 'subject one' and the safe driving skills under complex conditions and emergency handling in dangerous situations, placing them after the actual road driving test of 'subject three' to further test the traffic quality level of the candidates.

What is the normal range for the oil dipstick?

Oil dipstick readings between the lower and upper marks are considered normal. Typically, an oil dipstick has two marked lines, and during routine vehicle checks, the oil level should be between these two lines. If the oil level is below or close to the lower mark, oil should be added. Below are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and pistons, reducing gas leakage and preventing contaminants from entering. 3. Rust prevention: Lubricating oil adheres to part surfaces, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When cylinder pressure rises sharply, suddenly increasing the load on pistons, piston rings, connecting rods, and crankshaft bearings, the lubricated transmission of this load through the bearings helps cushion the impact. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil pan through circulation, flushing away contaminants generated on the working surfaces of the parts.

What is the ME7?

ME7 is the first pure electric SUV launched by Skywell Auto in September 2020. Skywell Auto was established in 2015, and after five years of development, the ME7 was designed. In terms of intelligent technology, the ME7 is equipped with five screens inside the car: a 12.3-inch full LCD instrument panel, a 15.6-inch central control screen, a 12.3-inch co-pilot entertainment screen, and two 12.8-inch rear entertainment screens. The three high-definition screens in the front row are closely connected with the ambient lighting of the starry sky. Among these five screens, through online operation, passengers in the rear can borrow the screen to set navigation routes from the driver's seat or share images throughout the vehicle. The Skywell ME7 is equipped with the latest generation of permanent magnet synchronous motor, with a maximum output power of 160kW, a maximum torque of 330N, and a maximum rotation speed of 12000rpm, ensuring an ultra-long range of 530 kilometers. In addition, the Skywell ME7 also features designs such as a smoked sports package and full-series standard LED lights.

What is the reason why the car air conditioner only has wind at the 4th speed?

The reason why the car heater switch only has wind at the fourth speed is due to the burnout of the heater blower speed control resistor. Specific information is as follows: 1. The solution is to promptly go to the car's 4S shop or repair shop to replace the heater blower speed control resistor, which can solve the problem of the car heater's air outlet failure. 2. Automatic air conditioning and manual air conditioning: Both automatic and manual car air conditioners are similar when turning on the heater. They both adjust the temperature by rotating the temperature control button, with the red area indicating an increase in temperature. However, the automatic air conditioner can set a specific temperature, and it will automatically adjust based on the temperature inside the car. Some car owners, afraid of the cold, turn on the heater immediately after starting the vehicle, thinking it will quickly raise the interior temperature, but this method is actually not effective.

What is the appropriate tire pressure for Nissan Sunny?

The standard tire pressure for Nissan Sunny is 2.4-2.5 bar. Tire pressure may vary depending on different brands and models. Factors such as seasons and load conditions also affect it. The specific recommended pressure can usually be found on the fuel tank cap, the side of the driver's door, or in the user manual. Tire pressure is an indicator of a vehicle's load capacity. The load capacity of a car depends on the tire pressure. According to the relationship between the tire load index, tire pressure, and load capacity, higher tire pressure increases load capacity, while lower pressure reduces it. Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. When a car is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance. Tire pressure significantly affects the rolling resistance coefficient. When the pressure decreases, the rolling resistance coefficient increases rapidly because lower tire pressure causes greater tire deformation and increased hysteresis loss. Therefore, proper tire pressure ensures good vehicle performance.

Can Diesel No. 0 and -35 Be Mixed?

Mixing half No. -35 diesel and half No. 0 diesel is acceptable. The diesel grade is merely an indicator of the fuel's resistance to congealing. The smaller the number in the diesel grade, the stronger its resistance to congealing. However, the diesel grade cannot be used as a basis for judging fuel quality. The anti-freezing capability of a mixture of half No. -35 diesel and half No. 0 diesel is certainly not as strong as that of pure No. -35 diesel. Therefore, when refueling, it is advisable to choose based on the actual local temperature. Below is an introduction to diesel usage: No. 5 diesel is suitable for use at temperatures above 8°C; No. 0 diesel is suitable for use at temperatures between 8°C and 4°C; No. -10 diesel is suitable for use at temperatures between 4°C and -5°C; No. -20 diesel is suitable for use at temperatures between -5°C and -14°C; No. -35 diesel is suitable for use at temperatures between -14°C and -29°C; No. -50 diesel is suitable for use at temperatures between -29°C and -44°C or below.
