Is the H7 bulb for low beam or high beam?

H7 bulb is a universal model that can be used for both low beam and high beam. More information about bulb models: 1. The H7 has two pins and one positioning tab on the edge, mostly used for low beam, while some fog lights also use H1 or H7. 2. Different vehicle models use different bulb types. The H4 is a dual-filament bulb (high/low beam) with three pins and three positioning tabs on the edge, generally used in Japanese and Korean cars. H1 and H7 are mostly used for high and low beams in European cars. 3. There are many automotive bulb models, mainly divided into H and D types, which can be distinguished by the number of pins and positioning tabs. Common models include H1, H3, H4, H7, H11, etc., with different bulb models used for different positions.

What is the structure of a hydraulic power steering system?

Introduction to the structure of hydraulic power steering system: The hydraulic power steering system mainly consists of two parts: mechanical components and hydraulic power assist devices. The mechanical components include the steering transmission pair, steering rocker arm, longitudinal rod assembly, transverse rod assembly, steering knuckle arm, steering kingpin, steering knuckle kingpin sleeve, steering knuckle pressure bearing, and steering knuckle. Below is a related introduction to the hydraulic power steering system: 1. The hydraulic power steering system is based on a mechanical steering system with the addition of a steering power assist device. The steering power assist device of the hydraulic power steering system mainly consists of a steering oil reservoir, steering hydraulic pump, and steering control valve. Hydraulic power steering is classified into constant-flow and constant-pressure types based on the fluid flow form, and can be further divided into spool valve and rotary valve types based on the form of the distribution valve. 2. This device can reduce the force required by the driver to turn the steering wheel, allowing the driver to feel the necessary road conditions acting on the wheels through the steering wheel, commonly known as road feel. It can prevent the impact force from rough roads from being directly transmitted to the steering wheel, making steering easier and more flexible. It also improves the safety factor of the vehicle, especially in situations where a tire blowout occurs during high-speed driving. With this steering system, the driver can effectively adjust the vehicle's direction to prevent severe traffic accidents.

What is the reason why the anti-skid light stays on and cannot be turned off?

When the anti-skid light is on, it indicates that the ESP system is turned off or has malfunctioned. The reasons for the anti-skid system light to illuminate are as follows: 1. Accidentally pressing the ESP system's off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 5. Software issues causing poor signal transmission; 6. ABS pump failure. Methods to turn off the anti-skid light: 1. Restart the engine and briefly press the ESP-OFF button on the vehicle to check if the anti-skid light was accidentally turned off; 2. Take the vehicle to a 4S shop for inspection, use a specialized fault diagnostic tool to locate the issue, and after repair, use a decoder to clear the fault code. Once the ESP system is confirmed to be working normally, the anti-skid light will turn off.

How to Determine When to Replace Spark Plugs?

The main signs that spark plugs need replacement are noticeably high fuel consumption and sluggish vehicle performance with unresponsive throttle. 1. Difficult starting. Whether cold or warm starts, it's nearly impossible to start the engine immediately - even successful starts take 5-6 seconds. This occurs because the spark plug electrodes are severely worn, with rounded edges around the center electrode, resulting in weak and unstable spark discharge. Additionally, excessive spark plug gap leads to insufficient spark intensity and weak penetration power, making it difficult to ignite the air-fuel mixture. 2. Increased fuel consumption. Normal consumption of 7-8 liters per 100km may suddenly jump to over 10 liters. The exhaust pipe emits not just fumes but practically spews money as refueling frequency increases. 3. Noticeable power loss during hill climbs or rapid acceleration. Especially when carrying passengers, the vehicle won't respond even with full throttle. This happens because deteriorating spark plug performance increases misfire rates, causing incomplete combustion of the air-fuel mixture and failure to achieve the engine's designed maximum power output. Spark plug replacement intervals: Under normal maintenance conditions, replacement is recommended at 40,000-60,000 km, though this varies by brand and engine type (consult your owner's manual). Reference these general standards: • Platinum spark plugs: replace at 40,000 km • Standard nickel alloy spark plugs: replace at 20,000 km • Iridium spark plugs: replace at 60,000-80,000 km

How to Use Rearview Mirrors When Reversing?

Method for using rearview mirrors when reversing: When reversing, pay attention to observing the left and right rearview mirrors. To adjust the left rearview mirror, position the horizon in the center, with the left and right positions adjusted so that the car body occupies one-fourth of the mirror's area. For the right rearview mirror, place the horizon in the upper two-thirds to allow more ground visibility, with the left and right positions the same as the left mirror. Control the vehicle speed when reversing and avoid pressing the accelerator if possible. Below are some precautions for reversing: 1. Always check for pedestrians or electric bikes behind you when reversing. Slow down to minimize danger in case of an accident. 2. When making a U-turn or reversing on a wider road, you can directly judge the position of the rear or wheels on the road through the rearview mirror. On narrower roads, if you cannot accurately determine the position of the rear and rear wheels from the mirror, open the door and observe the rear wheels while operating. When making a U-turn or reversing at intersections or street corners, expand the rear visibility and range, and be cautious of passing vehicles, pedestrians, and bicycles.

Is an ignition advance angle of 12 degrees or 9 degrees better?

An ignition advance angle of 9 degrees is better, for the following reasons: The ignition advance angle is generally between 6 and 12 degrees. A 12-degree ignition advance angle is too large compared to 9 degrees, which can lead to delayed ignition. If ignition is delayed, the gas will have difficulty performing work, fuel consumption will increase, efficiency will decrease, and exhaust noise will also increase, affecting the engine's working efficiency. Additional information: Ignition advance refers to the spark plug firing before the engine piston reaches the top dead center of compression. The angle through which the crankshaft rotates from the moment the spark plug fires until the piston reaches the top dead center of compression is called the ignition advance angle.
