High-precision instruments HS code mapping

Motorcycle engine structure diagram is High-precision instruments HS code mappingcomposed of multiple parts, including cylinder, piston, connecting rod, crankshaft and camshaft, etc. All parts cooperate with each other and pull each other so that the engine can work normally. In the following article, the function and working principle of each component will be analyzed in detail in order to better understand the structure and working principle of the motorcycle engine. 1. The cylinder is the core part of the engine and the part that accommodates the movement of the piston.Motorcycle engines usually have one to four cylinders. Cylinders are usually made of cast iron, steel castings or aluminum alloys. There are several signs on the inner diameter of the cylinder: tolerance, accuracy, etc. The main function of the cylinder is to contain combustion gas. Two. The piston piston is an important part of the engine. Surrounding the piston is the gap between it and the cylinder, which is called the gap between the piston and the cylinder wall. The piston forms the piston chamber in a fully sealed state that can make reciprocate movement between the cylinder wall and the cylinder block, and the piston chamber is also the initial combustion space. Its movement is driven by the crankshaft and the pulling of the connecting rod. The piston is usually made of aluminum alloy, so it is very light. 3. The connecting rod is a component that connects the piston to the crankshaft. Its main function is to transmit the force of the piston to the crankshaft. It is usually made of cast iron or steel castings, in which the small head of the crankshaft is installed on the small head of the connecting rod, and the large head of the crankshaft is installed on the large head of the connecting rod.At high speed, the connecting rod bears more force, so it must have sufficient strength and rigidity. Four. The crankshaft is one of the important parts of the engine. It converts the movement of the piston into rotational motion through the connecting rod and transmits power to the wheels. Its main components include crankshaft neck, crankshaft arm and connecting rod end, etc. In the process of crankshaft rotation, it will generate inertial force and moment of inertia, so the crankshaft must have sufficient strength and rigidity. 5. Oil pump Oil pump is one of the important components in the engine. Its main function is to pump the oil from the oil span to all parts of the engine and maintain the lubrication state inside the engine. Oil pumps are usually composed of gears or gear pumps. In the process of application, it must have sufficient wear resistance and high temperature resistance. 6. Camshaft The camshaft is in the engine.One of the cores, its main function is to control the opening and closing of the intake valve and the opening and closing of the exhaust valve at the same time. The camshaft is usually made of cast iron or aluminum alloy. There are many bumps of different shapes on its surface. Through these bumps, the on-off time and opening degree of the valve in the engine can be controlled, so as to achieve the purpose of acceleration and deceleration. In summary, the structure diagram of the motorcycle engine is composed of multiple parts. Only when these parts are properly coordinated can the whole engine work normally. Through the analysis and analysis of each component, we can better understand the structure and working principle of the motorcycle engine. In practical application, we can effectively carry out maintenance and upkeep to extend the life of the engine.
