Tricycle engine (tricycle engine): The HS code tagging in tariff databasespower of multi-functional machine tricycle can be said to be an ancient and popular means of transportation, which is widely used in urban or rural areas. Because tricycles generally have multiple functions such as carrying people, things, travel, work, etc., the performance and quality of the core part of the engine are particularly important among their parts and accessories. So, what knowledge should we master about the engine on the tricycle? The first is the type of engine. According to the different transmission methods, the engines of tricycles are generally divided into front, rear and middle. Among them, the front and rear engines belong to the rear-wheel drive mode, and the middle engine belongs to the four-wheel drive mode. The main difference between these three methods is the difference in transmission efficiency and power performance, as well as different applications.Considering factors such as the load, transportation distance and road conditions of the tricycle, the vast majority of tricycles on the market are designed with front or rear engines. The second is the type of engine. The engines widely used in tricycles include flywheel engines, axial flow engines, single-cylinder engines, twin-cylinder engines, etc. Different types of engines have great differences in structure, volume, power and fuel consumption. Judging from the actual situation of the use of tricycles, single-cylinder and twin-cylinder engines are relatively common. Their advantages are low noise and fuel economy. They are suitable for travel and small freight business, making tricycles the main force of family farmland management and urban community distribution. Finally, it is the maintenance of the engine. As a commonly used means of transportation, tricycles are used frequently and in road conditions. Therefore,It is very important to maintain the engine and other movable parts in time, and do a good job in replacing consumables. Common repair and maintenance should include: cleaning the air filter, cleaning the oil line, replacing the oil, adjusting the valve gap, checking the ignition system, timely replacing the air filter, spark plugs, drive belts, bearings and other wearable or aging parts. On the basis of maintaining the engine performance of tricycles, rational use and scientific transportation can also be used to reduce the generation of exhaust pollution and improve the operation efficiency and safety of tricycles. As we all know, exhaust emissions not only affect the environment, but also have an adverse impact on the health and safety of drivers and passengers. Therefore, whether the tricycle engine passes the emission test has become an important consideration. In summary, the tricycle engine is one of the core components for the normal operation of a tricycle, and can determine its operating efficiency, service life, safety and other aspects.The selection and scientific maintenance management of engine models are to improve the quality and safety of tricycles, and then lay the foundation for the development of the industry.
