White semicircular distance confirmation markings are installed every 50 meters on both sides of road sections with complex meteorological conditions that affect driving safety, serving as a reference for drivers to maintain a safe following distance. Below are three types of distance confirmation markings: White zigzag distance confirmation markings: These markings have a total width of 300cm with line widths of 40cm or 45cm. Starting from the 0m reference point, they are placed every 5 meters in pairs, with a 50m interval between groups. Five sets are typically installed, though more may be arranged based on site conditions. White semicircular distance confirmation markings: These semicircular markings have a radius of 30cm and are spaced 50m apart, usually installed consecutively along certain road sections. White rectangular distance confirmation markings (expressway distance confirmation markings): Used in conjunction with distance confirmation signs, these are installed on sections prone to overtaking, accidents, or other hazardous conditions.

How to Adjust the Carburetor to Optimal Condition?

You can use the three-high three-low method, which involves first adjusting the mixture ratio to make the engine speed reach its highest, then adjusting the idle speed to make the engine speed reach its lowest point, and then adjusting the mixture ratio again. Repeat this cycle three times, and finally slightly increase the idle speed. This way, the carburetor of the vehicle can operate at its optimal condition. There are usually two types of carburetor mixture ratio screw adjustments, with the actual effects after adjustment being: 1. Air-adjusting type: Turning clockwise to tighten increases the richness of the gasoline mixture, while turning counterclockwise reduces the richness and increases air. 2. Fuel-adjusting type: Turning clockwise to tighten increases the air intake and reduces the fuel intake, i.e., leans the mixture; turning counterclockwise reduces the air intake and increases the fuel intake, i.e., enriches the mixture.
