How Many Types of White Car Paint Are There?

Automotive white paint can be categorized into four types: Pearl White, Ivory White, Cream White, and Crystal White. Below is a detailed introduction: 1. Pearl White and Ivory White: Pearl White and Ivory White are paint formulations that incorporate pearl powder or mica flakes. Although they may slightly lack in color accuracy (white), the complex light refraction and interference they create result in an outstanding overall visual effect, making them more distinctive. 2. Cream White and Crystal White: Cream White and Crystal White paint types offer a pure white appearance without transitions or blends of other colors. While the color may seem relatively simple, under sunlight, the paint's gloss level becomes noticeably apparent.

What is the function of valves?

The function of valves is specifically responsible for introducing air into the engine and expelling exhaust gases after combustion. In terms of engine structure, they are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Here is additional information: 1. Composition: A valve consists of a valve head and a stem. The shape of the valve head can be flat, spherical, or trumpet-shaped, among others. Flat valve heads are simple in structure, easy to manufacture, have a small heat absorption area, and are lightweight, making them suitable for both intake and exhaust valves. The valve stem is cylindrical and continuously moves back and forth in the valve guide, requiring its surface to be heat-treated and polished. The shape of the valve stem end depends on the method of fixing the valve spring, with the common structure using two half-lock pieces to secure the spring seat. The valve stem end has a groove for installing the lock pieces, while some use a lock pin for fixation, with a hole at the end for installing the lock pin. 2. Current Status: To improve intake and exhaust efficiency, multi-valve technology is now widely used, commonly featuring four valves per cylinder (though some designs have three or five valves per cylinder, following the same principle, such as the Audi A6's engine). For a four-cylinder engine, this totals 16 valves, often indicated as "16V" in automotive specifications. This multi-valve structure easily forms a compact combustion chamber, with the fuel injector positioned centrally, allowing the air-fuel mixture to burn more quickly and uniformly. The weight and opening of each valve are appropriately reduced, enabling faster opening and closing speeds.

What are the lengths of concrete pump trucks?

There are 7 common specifications for the length of concrete pump trucks, which are 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters, 35 meters, and 37 meters. Below is the relevant introduction: 1. Boom-type concrete pump trucks: Initially, domestic boom lengths were mostly 37 meters, but in recent years there has been a trend towards longer booms. In the coming years, as demand continues to grow, concrete pump trucks with even longer booms will enter the market. 2. Delivery cylinder: Concrete pump trucks use large-diameter, long-stroke delivery cylinders to increase the suction area and reduce the number of directional changes per unit time, thereby decreasing the wear on the delivery cylinder, concrete piston, wear plate, and cutting ring, directly extending their service life.

How Many Years Are 7-Seater Vehicles Exempt from Inspection?

7-seater vehicles are exempt from inspection for 6 years. Starting from November 20, 2020, 7-seater vehicles have been officially included in the exemption scope. For 7-seater vehicles within 6 years, when a biennial periodic inspection is required, the vehicle owner can directly apply to the traffic management department of the public security authority for the inspection label by providing the compulsory traffic accident liability insurance certificate, and the tax payment or exemption certificate for vehicle and vessel tax, without the need to undergo safety technical inspection at an inspection institution. Inspection cycle: For 7-seater vehicles over 6 years but under 10 years, the inspection cycle has been relaxed from once a year to once every two years, meaning only 2 on-site inspections are required within 10 years, specifically in the 6th and 8th years (also effective from November 20, 2020). For vehicles over 10 years, an annual inspection is required; for those over 15 years, a semi-annual inspection is required. For on-site inspections, 7-seater vehicle owners or agents need to bring their ID card, vehicle license, compulsory traffic insurance certificate, and vehicle and vessel tax payment certificate to the local vehicle inspection institution for the annual inspection. Inspection items mainly include vehicle detection, safety inspection, exhaust emission testing, etc. Newly added items now include appearance inspection, OBD check, fuel evaporation detection, and adjustment of pollutant emission limits.

What to Do When Small Cracks Appear on Car Tires?

Minor cracks do not affect usage, but if there are numerous and deep cracks, it is recommended to replace the tire. Below is an introduction to tire cracks: 1. Tire Material: Tires are made of rubber, and rubber exposed to air and sunlight will oxidize. When tires oxidize, they become harder. Therefore, after a period of use, small cracks may appear on the tire beads, especially on harder and more wear-resistant tires, which are more prone to such issues. 2. Tire Lifespan: The general lifespan of a tire is three years. During vehicle use, it is recommended to replace tires every two years, regardless of how deep the tread remains. For the safety of the driver, replacement is advised.
