What speed corresponds to each gear while driving?

Which is More Important: Maximum Horsepower or Maximum Torque?

Both maximum horsepower and maximum torque are important. Maximum Horsepower: Refers to the maximum power output a vehicle can achieve, measured in PS (Pferdestärke), which is equivalent to the maximum power data. Power is defined as the work done by an object per unit of time. The higher the power, the higher the rotational speed, and the higher the top speed of the vehicle. Maximum power is commonly used to describe a car's dynamic performance. The level of maximum horsepower affects a car's top speed, while torque influences the force during acceleration, including initial acceleration. Theoretically, the greater the torque, the faster the initial acceleration, resulting in a shorter time from 0 to top speed. If a car has high horsepower but low torque, acceleration will be very slow, making the driver feel the car lacks power. Maximum Torque: This is the moment output by the engine from the crankshaft end, measured in N·m/rpm (Newton meters per revolution per minute). Maximum torque typically occurs in the engine's mid to low RPM range. As the RPM increases, torque tends to decrease.

What Type of Fire Extinguisher Should Be Kept in a Car?

Dry powder fire extinguishers and water-based fire extinguishers should be kept in cars. The usage scenarios and relevant regulations for different types of fire extinguishers are as follows: Usage scenarios for different fire extinguishers: Common causes of car fires include electrical fires and fuel leakage fires. For electrical fires, water-based mist extinguishers are more suitable; for fuel fires, water-based foam extinguishers are preferable. Dry powder fire extinguishers, on the other hand, offer good versatility and a wide range of applications, making them suitable for both types of fires mentioned above. Relevant regulations: Medium-sized and larger passenger vehicles, as well as hazardous goods transport vehicles, must be equipped with valid fire extinguishers and firefighting equipment. Failure to comply may result in warnings or fines. Although there are no strict regulations for private cars regarding fire extinguishers, during annual vehicle inspections, a fire extinguisher must be present in the car; otherwise, the inspection will not be passed. For safety reasons, it is recommended to equip your vehicle with a fire extinguisher.

Can You Pick Up the Car in Heavy Rain?

You can pick up the car in heavy rain. However, if visibility is too low due to a heavy downpour, it is recommended to reschedule the pickup to avoid traffic accidents caused by unfamiliarity with the new car's operation, which would be counterproductive. The precautions for picking up the car are as follows: Inspect the car's paint surface: First, check whether the car's paint surface is intact, especially at prominent edges such as the front and rear bumpers, and ensure there is no damage. Next, verify that the paint color is consistent and free of scratches or other defects. Check the tires: Also, inspect whether the tire tread hairs are intact. The presence of tread hairs indicates that the car has not been driven extensively, as new cars typically retain them. Additionally, check the car's manufacturing date. If it exceeds three months, it may be considered stock inventory, and you can request the manufacturer to replace it with a new one.

What is the problem when the Volkswagen Tiguan fan does not turn?

Reasons why the Volkswagen Tiguan fan does not turn: Water temperature not reaching the required level: Most car radiator fans nowadays operate using electronic temperature control. Therefore, the fan usually starts turning normally only when the internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not turn. Hence, when the car radiator fan fails to turn, the first thing to check is whether the water temperature has reached the required level. Relay malfunction: If the water temperature meets the requirements but the car radiator fan still does not work, the issue might be with the fan relay. If the relay malfunctions, the car's radiator fan cannot operate. Thermostat switch problem: If there are no issues with the above two aspects, then the thermostat switch should be checked. Sometimes, faults can occur in this area, which can also affect the operation of the car radiator fan. Therefore, it is important to inspect this as well.

What is the Scrapping Period for Private Cars?

Private cars do not have a mandatory scrapping period. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. The difference between guided scrapping and mandatory scrapping: Guided scrapping is a recommendation for scrapping, but if the vehicle still meets the requirements for continued use, it does not have to be scrapped. Mandatory scrapping means the vehicle must, without exception, be scrapped. There are four criteria for mandatory scrapping: reaching the stipulated service life; failing to meet the national safety technical standards for in-use vehicles even after repairs and adjustments; failing to meet national standards for pollutant emissions or noise from in-use vehicles even after repairs, adjustments, or control technology implementation; and failing to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection period. Motor vehicle scrapping process: The owner of the car applying for scrapping and renewal must fill out and submit one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form," stamped with the owner's seal. Apply at the registration and acceptance counter. For vehicles that have reached the scrapping age, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping age, after inspection and confirmation by the motor vehicle inspection counter that they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice." The recycling company will dismantle the vehicle and take photos after verifying the "Notice." The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form," "XX Province Vehicle Renewal Technical Appraisal Form," "Scrapped Vehicle Recycling Certificate," and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates will be reclaimed, and the scrapping registration will be processed according to regulations after approval.

Is There a Difference Between Refueling in the Morning and at Noon?

There is no difference between refueling in the morning and at noon. Below are some precautions regarding the use of automotive fuel: Difference between 95 and 92 octane fuel: 95 octane gasoline consists of 5% n-heptane and 95% isooctane, while 92 octane gasoline consists of 8% n-heptane and 92% isooctane. The higher the octane number of the gasoline, the stronger its anti-knock properties, but the price will also be higher. 95 octane gasoline has a higher octane number than 92 octane gasoline, so in terms of stability, 95 octane gasoline burns more easily than 92 octane gasoline and delivers more power. 95 and 92 octane fuels should not be mixed for long-term use: Occasionally, in special circumstances, mixing the two fuels when refueling generally won't cause major issues, but long-term use is not recommended as it can lead to knocking, insufficient power, and other problems. Similarly, using 92 octane gasoline occasionally in a vehicle designed for 95 octane won't cause major issues, but long-term use will increase the frequency of knocking and accelerate engine wear.
