Electric power steering in cars is composed of components such as a torque sensor, vehicle speed sensor, electronic control unit (ECU), electric motor, and electromagnetic clutch. It utilizes the power generated by the electric motor to assist the driver with steering. Working principle: The torque sensor is connected to the steering shaft. When the steering shaft rotates, the torque sensor activates, converting the relative angular displacement between the input and output shafts caused by the torsion bar into electrical signals, which are then transmitted to the ECU. Electric power steering systems have evolved from traditional mechanical steering systems, using the power generated by an electric motor to aid the driver in steering operations. The electric power steering system primarily consists of three major components: signal sensing devices, steering assistance mechanisms, and electronic control devices.

How often should the spark plugs of Volkswagen Tiguan be replaced?

The recommended replacement interval for the original spark plugs of the Volkswagen Tiguan is 40,000 to 60,000 kilometers, using NGK double platinum spark plugs with the model number PFR7S8EG. Spark plug replacement cycle: Under normal maintenance conditions, replacement is required after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to refer to the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.

What do L1, L2, and L3 represent in a car?

L1 refers to first gear, where the transmission is locked in first gear and will not upshift. This gear can be used for steep uphill or downhill driving. L2 indicates that the gear can shift between first and second gear, with the highest gear being second. L3 means the gear can shift among first, second, and third gears, with the highest gear being third. Additional information: The function of D gear: 1. D gear is used for normal road driving and is the most commonly used driving position. During normal driving, placing the gear in D allows the car to automatically shift between 1st and 3rd (or 4th) gears. 2. Another feature of D gear is forced downshifting, which is useful for overtaking at high speeds. While driving in D, quickly pressing the accelerator pedal to the floor activates the forced downshift switch, automatically downshifting the gear. The car accelerates quickly, and releasing the accelerator pedal will automatically upshift again. 3. D1 gear, driving gear: fixed in 1st gear (used for steep slopes). D2 gear, driving gear: fixed in 2nd gear (used for starting on snowy roads). D3 gear, driving gear: automatically switches between D1-D3 gears.
