Engine internal structure (internal structure revealed: engine operation secret) When we step on DigiPlusthe accelerator, the car will continue to accelerate. This is because the engine of the vehicle converts chemical energy into mechanical energy through various mechanical devices. However, many people don't know that there is a complex mechanical structure behind all this. In this article, I will reveal the secrets inside the engine and show you how the engine works. The most common type of engine is an internal combustion engine, which uses the combustion of fuel to generate power. This engine requires three basic conditions to work: fuel, air and spark/compression.Sparks ignite the mixed gas, and compression makes the mixed gas spontaneously ignite without sparks. In an internal combustion engine, combustion is completed by the piston (OSW) in the cylinder, which is connected to the crankshaft (CRAN) through the connecting rod (CR) to convert the linear motion of the piston into the rotational motion of the crankshaft. In the internal structure of the engine, the piston and connecting rod are its most important parts. The piston is located in the cylinder and is usually a metal rod used to compress fuel and air. In a gasoline engine, when the piston enters the cylinder, it compresses the mixture to the maximum pressure and then ignites the mixture. When the mixture burns, the piston is pushed down to push the connecting rod. The connecting rod converts the linear motion of the piston into the rotational motion of the crankshaft. This movement will be transmitted to the wheels to push the vehicle forward. The crankshaft is another important part of the engine.It rotates under the action of connecting rods and pistons. When the crankshaft rotates, it drives the movement of the wheels. If the crankshaft rotates unsteadily, the vehicle will cause bumps, and if it is serious, it will also cause mechanical failure. Therefore, the manufacture of crankshafts requires very fine processes and manufacturing standards to ensure its stable and smooth rotation. There are many other key parts inside the engine, such as valves, piston rings and valve rods. The valve is the component that controls the entry and discharge of fuel and air into the cylinder. The piston ring is a ring-shaped part close to the piston. Its main function is to prevent gas leakage in the combustion chamber. The valve lever is responsible for controlling the opening and closing of the valve. To sum up, the internal structure of the engine is extremely complex. Each of these parts has its own function, and problems with any part may lead to the failure of the entire engine, thus endangering the safety of the driver.Therefore, when maintaining a car, detail and accuracy are crucial, and it is necessary to be careful of the wear and aging of mechanical parts. Only in this way can we better understand the internal structure of the engine, maximize the performance of the car, and improve our driving safety and comfort.
