Single-cylinder engine illustration (single-cylinder engine operation principle illustration) Single-cylinder engine is HS code tagging in tariff databasesa simple and effective internal combustion engine.It only uses one cylinder, not two or more cylinders of a multi-cylinder engine. Although it is relatively simple, the single-cylinder engine is still an important source of power widely used in lightweight vehicles such as motorcycles, small cars and light aircraft. In this article, we will introduce the principle, components and operation process of a single-cylinder engine in detail. The principle of single-cylinder engine The basic principle of single-cylinder engine is the same as that of other internal combustion engines. It uses combustion to release energy and push the piston back and forth in the cylinder to drive the vehicle. Each cylinder consists of a piston, a valve, an igniter and a fuel injector. The valve controls the inflow and outflow of gas, the igniter ignites the fuel, and the injector mixes the fuel into the cylinder to generate energy. Components of a single-cylinder engine A single-cylinder engine consists of the following components: 1.Piston: The piston is the core part of a single-cylinder engine. In operation, it drives the engine in the same way as before. The piston is made of metal and combined with the swing of the progressive camshaft to achieve gas and compression. At the same time, the piston also helps to control the position of the valve and injector of the cylinder. Two. Valve: The valve is a device that cuts off the connection between the cylinder and the external gas. It allows fresh gas to enter the cylinder, and it also exhausts air during compression and combustion. 3. Ignitioner: The ignitioner is used to ignite a gas mixture. While the engine is down, the pressure will rise and lead to gas liquefaction. The igniter ignites the gas with an electric spark, thus releasing energy. Four. Fuel injector: The fuel injector is the control center of the engine. It consists of an electronic controller, a fuel pump and an injector, which makes the engine run smoothly by generating a mixture and spraying it into the cylinder.The working process of the single-cylinder engine The working cycle is the working process of the single-cylinder engine, which is divided into four steps: I. Intake: In this cycle, the piston moves down to inhale fresh air and fuel smoke into the cylinder to prepare for combustion. II. Compression: In this cycle, the piston moves upwards to compress the gas into a high-pressure state. Release more energy through a mixture of compressed air and fuel. III. Combustion: In this cycle, the igniter ignites the mixture. When the mixture is burned, heat and compression are generated to push the piston down and drive the vehicle forward. IV. Exhaust: In this cycle, the piston moves up again to exhaust the exhaust and complete the whole working cycle. To sum up, a single-cylinder engine is a simple and effective engine. Although it uses only one cylinder, it works the same as other internal combustion engines.Each cylinder consists of a piston, a valve, an igniter and a fuel injector. In the working cycle, it realizes the operation of the engine through the four steps of inhalation, compression, combustion and exhaust. Single-cylinder engines are one of the commonly used power components for lightweight vehicles (such as motorcycles, small cars and light aircraft).
