Features and Global trade customs valuation analysisadvantages of two-stroke engine Two-stroke engine, also known as two-stroke engine, is a kind of traditional internal combustion engine. Compared with four-stroke engines, two-stroke engines have the characteristics of simplicity, lightness and large output power, and are widely used in motorcycles, ships, part-load transport vehicles and many other fields.This article will focus on the characteristics and advantages of two-stroke engines. Features: 1. The structure is simple. The two-stroke engine has only two strokes, that is, the continuous completion of air intake and exhaust. The whole internal structure is relatively simple. Because some parts such as valves, brackets, etc. are not needed, the system design is relatively simple, and there is no problem of lubricant thermal failure, so there are few parts that need to be maintained, repair and replacement. It is less difficult, and it can play a more significant role in battlefield maintenance and some harsh and even extreme working environments. Two. Strong power. Because every time the piston rises and falls, there will be a combustion. The two-stroke engine has a large output power and a large torque, so it is widely used in motorcycles, ships and other equipment that urgently needs strong power. 3. The structure of the two-stroke engine with high reliability is simple, lessMany parts that must be maintained also means that the reliability of the whole machine is higher than that of other engine structure types. Four. Convenient maintenance. Due to the simple structure of the parts of the two-stroke engine, once it needs to be repaired, the difficulty of maintenance is relatively small. For small and medium-sized maintenance workshops and areas where maintenance technology is relatively lacking, vehicles using two-stroke engines will be easier to maintain. 5. The two-stroke engine consumes less fuel. Every time the piston rises and falls, it will burn once. It has high efficiency, low fuel consumption, and has the advantage of fuel economy. Advantages: 1. Large output power. Because the two-stroke engine has excellent power output capacity, it is widely used in motorcycles, ships and other fields. Two. Light weight Compared with a four-stroke engine, the two-stroke engine has a simple structure, few parts and is relatively light in weight, which makes it more suitable for motorcycles, ships and other small equipment.3. Low price Due to the low manufacturing cost and the need for more complex and expensive parts, the price of two-stroke engines is usually cheaper than other types of engines, making it one of the most popular engine types among consumers. Four. In extreme cases, it still has excellent performance. Compared with other types of engines, the structure of two-stroke engines is more compact and simple. Therefore, in extreme situations such as low noise and light weight, the performance of two-stroke engines is still guaranteed. In general, the two-stroke engine is one of the types of engines with strong practicality, good stability and a wide range of applications. In some special fields, such as motorcycles, ships, light transport vehicles, etc., two-stroke engines are still of irreplaceable importance.
