The advantages of multi-point fuel injection are high efficiency, fuel economy, and mature technology, as detailed below: High combustion efficiency: Compared to traditional single-point fuel injection technology, multi-point fuel injection has electronic fuel injectors installed in each intake manifold, forming a mixture in the intake pipe. The mixture is more uniform, so the combustion efficiency is higher than that of traditional single-point fuel injection. Higher combustion efficiency means the engine's output power is greater. More economical and fuel-efficient air-fuel ratio control: Compared to traditional single-point fuel injection technology, multi-point fuel injection technology can adopt sequential injection, so the control of the air-fuel ratio is higher and more precise than traditional methods. This reduces toxic emissions and is more economical and fuel-efficient. Mature technology: Whether compared to traditional single-point fuel injection technology or newly developed direct injection technology, multi-point fuel injection technology has been developed for some time and is superior to the former two in terms of engine break-in and economy.

How Long Can Car Headlight Polishing Last?

Car headlight polishing can last for two to three years. Here are some precautions for car headlight maintenance: 1. Replacement: Car headlights should maintain good sealing, especially to prevent contamination and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the mirror surface with fingers to prevent leaving sweat or oil marks that could cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular Inspection: Regularly check and adjust the headlight beams to ensure the illumination distance meets requirements and that the bright light beams are consistent vertically. The diffuser glass should be correctly installed as specified to prevent loosening or displacement, maintaining the vertical alignment of the prisms.

What is the plastic buckle on the seat belt called?

The plastic buckle on the seat belt is called a seat belt buckle. A seat belt buckle is a device that can be inserted into the seat belt socket of a car, preventing the seat belt alarm from sounding when the driver is not wearing the seat belt.
