Electric power steering requires steering fluid. Electric power steering is an EPS system, which is a power steering system that directly relies on an electric motor to provide auxiliary torque. The electric power steering system does not have the hydraulic pump, hydraulic pipelines, or steering column valve structure of a hydraulic power steering system. Instead, it directly transmits the assistance generated by the motor to the steering system through a reducer in a purely mechanical manner. The electric power steering system consists of a steering column, torque sensor, servo motor, and control module. Its working principle is as follows: after the vehicle starts, the system begins to operate. When the vehicle speed is below a certain threshold, the signal is sent to the control module, which then issues control commands to the servo motor based on data such as the steering wheel's torque, rotation direction, and vehicle speed. This causes the servo motor to output torque of a corresponding magnitude and direction to generate assistance. When no steering is performed, the electronic control unit does not send torque signals to the servo motor, and the current of the servo motor tends toward zero.

What are the function keys of the Bora car?

Introduction to the function keys of the Bora car is as follows: Electronic Stability Program (ESP): Effectively prevents loss of control such as skidding or fishtailing. It is generally not recommended for drivers to manually turn it off. Hazard Warning Lights (commonly known as hazard lights): Used in special situations such as car breakdown or temporary parking, mainly to warn other vehicles. Parking Radar/Image: The central control screen displays the reversing image, and the radar will sound an alarm when detecting obstacles nearby. Driving Assistance System: Includes functions such as pre-collision protection, distance warning, and fatigue reminder. Auto Hold: When waiting at a red light, it relieves foot fatigue by automatically locking the wheels with the brake calipers. Pressing the accelerator again will allow the car to continue moving forward. Auto Start-Stop: During brief stops, the engine will shut off. When the driver's foot leaves the brake pedal, the vehicle will restart.

Will not having my vehicle inspected affect other cars under my name?

Not having my vehicle inspected will not affect other cars under my name. Small and micro non-operational passenger vehicles: Small and micro non-operational passenger vehicles must be inspected once every 2 years within 6 years; once every year after exceeding 6 years; and twice every year after exceeding 15 years. Operational passenger vehicles: Operational passenger vehicles must be inspected once every year within 5 years; and once every 6 months after exceeding 5 years. Trucks and large and medium non-operational passenger vehicles: Trucks and large and medium non-operational passenger vehicles must be inspected once every year within 10 years; and once every 6 months after exceeding 10 years. Motorcycles: Motorcycles must be inspected once every 2 years within 4 years; and once every year after exceeding 4 years.

Motorcycle: Charging or Refueling?

Motorcycles come in both electric charging and gasoline-powered types. Cost-effectiveness: An electric scooter typically has a maximum range of 50~60 kilometers per charge. Gasoline-powered motorcycles are more convenient for refueling, with a single tank lasting at least 100 kilometers for scooters. Performance: Electric scooters without speed modifications can only reach a maximum speed of 40~50 km/h. Current 110CC or 125CC motorcycles can exceed 80 km/h. Build quality and materials: Electric scooters generally have inferior build quality and materials compared to reputable brand motorcycles (excluding knockoff motorcycles). A well-maintained reputable brand motorcycle can last over 10 years with careful riding. In contrast, electric scooters typically become unusable within 3~5 years. Moreover, electric scooters often use substandard materials along with poor craftsmanship, posing potential safety hazards.

Why Can't I Check My Driving Test Scores After Getting the License?

Reasons for not being able to check test scores after obtaining the driver's license are as follows: Platform reasons: After receiving the driver's license, the platform no longer retains test scores. The learning phase has ended, and you are no longer in the "driving student" status. Online query scores will not be retained. Conversely, some people can still schedule exams after getting their license due to system not being updated or errors. License levels: Driving licenses are divided into 16 levels: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, P. The sequence of vehicle types that motor vehicle drivers are permitted to drive is divided into: Large passenger vehicles, tractor-trailers, city buses, medium passenger vehicles, large trucks, small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, small automatic transmission passenger cars for disabled people, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams.

Can Engine Coolant Be Replaced with Cold Water?

Engine coolant cannot be replaced with cold water for the following reasons: High-temperature damage caused by replacing coolant with water: In the early days when automotive engine technology was not as advanced, the cooling medium used in car engine radiators was indeed water—plain water or tap water—and it was commonly added and used this way. Therefore, in the past, it was often observed that after driving for a relatively long time, the water in the radiator would boil, a phenomenon commonly referred to as "boiling over." At this point, the engine could not function properly, and the vehicle had to be stopped to wait for the water temperature in the radiator to decrease, along with the engine temperature, before continuing to drive. Low-temperature damage caused by replacing coolant with water: In colder climates, the issue of freezing at low temperatures needs to be addressed. Some substances added to coolant include those that lower the freezing point, giving coolant a much lower freezing point than water. This ensures that even at temperatures below zero or as low as -20 degrees Celsius, the coolant will not freeze. Coolant prevents corrosion and scale formation: Compared to the earlier practice of using plain water for cooling, modern coolant contains additives that provide anti-corrosion and anti-scaling properties. During long-term vehicle use, especially for rubber and metal piping, the continuous exposure to high and low temperatures in the cooling cycle can lead to corrosion if coolant is not used. Over time, accumulated corrosion can easily cause leaks or damage to related pipes and components, rendering the cooling system inoperable and subsequently preventing the engine from functioning properly.

What are the reasons for the abnormal noise when raising and lowering the Civic's windows?

The abnormal noise when raising and lowering the Civic's windows can be attributed to two main reasons: Dirty or obstructed door window rubber tracks: The door window rubber tracks may be dirty or have foreign objects. Unless they have just been cleaned, the door window tracks of every car accumulate dust over time, which can cause abnormal noises when the windows are raised or lowered. Aging door window rubber tracks: The door window rubber tracks may have aged. After all, the door window tracks are exposed to sunlight and rain, and over time, they naturally deteriorate. When raising or lowering the windows, you may hear abnormal noises caused by the aged rubber scraping against the glass. Solution: In this case, you can temporarily use a rubber protectant to restore some elasticity to the rubber and reduce the noise from friction against the glass, but this effect only lasts for about ten minutes. The best solution is to replace the tracks.
