Trade data for public policy design

* Engine schematic diagram (engine operation diagram: principle overview) The Trade data for public policy designengine of a car is the core component of the vehicle and is the key to achieving vehicle drive. It is very important for drivers to understand the principle and operation of the engine. In this article, we will deeply study the principle and operation mode of the engine, and briefly analyze how each part works together to achieve efficient operation of the engine. Engine schematic The basic principle of the engine is to convert the energy generated by fuel combustion into mechanical energy to drive the car.An engine is mainly composed of the following parts: 1. Cylinder block and cylinder head: the combustion chamber of the engine 2. Piston: The moving part of the engine, responsible for compressing gas and converting it into mechanical energy 3. Connecting rod: Convert the up and down movement of the piston into rotational motion and move on the engine hinge 4. Crankshaft: the core part of the engine movement, responsible for transforming the rotational movement of the connecting rod into the rotational movement of the engine 5. VALE: PARTS THAT CONTROL GAS INFLOW AND OUTFLOW OF THE ENGINE 6. Fuel injector: inject a mixture of fuel and air into the inside of the engine to provide energy for the engine 7. Spark plug: Generate high-voltage current to ignite the mixture, and combustion generates energy. After understanding the basic principle of the engine, we can further explore the operation mode of the engine. Below is a picture of the engine running.Illustration: The operation mode of the engine can be simply summarized into four steps: air intake, compression, combustion and exhaust. 1. Air intake: When the car is running, the valve opens and the air is sucked into the engine. After mixing with the sprayed fuel, it forms a flammable mixture in the combustion chamber. Two. Compression: The piston moves upwards to compress the mixture so that it can burn more easily and release more energy. In this process, the mixture is compressed and the piston is pushed down, and the kinetic energy generated by the expansion of the working gas is collected by the crankcase to convert the corresponding kinetic energy to output the hinge output interface. 3. Combustion: The spark plug emits high-voltage current, ignites the mixture, generates energy, and pushes the gas to move the piston down, while pushing the crankshaft to rotate to complete the work of the engine. Four. Exhaust: withThe piston moves upwards, the exhaust gas is discharged through the exhaust valve, and the engine returns to its original state to prepare for a new round of work. Efficiency and performance of the engine A high-efficiency engine can provide more powerful and reliable power. The speed of a car and maintaining a stable speed depend on the efficiency and performance of the engine. In actual use, some factors will lead to reduced efficiency of the engine, such as engine wear, fuel problems, oxygen problems and some factors. And these problems are often caused by the incoordination of the problem parts with other parts. In summary, the operation of the engine basically consists of four steps: intake, compression, combustion and exhaust. Each part needs to work with other parts to achieve efficient operation of the engine. For conventional power output, technological innovation has designed a new engine suitable for different models and wheelbases, and the forms are endless.For the future development trend of automobiles, we will pay more attention to the intelligent upgrading of engines, strive to innovate fuel efficiency and reduce automobile pollution, and make greater contributions to environmental protection and energy conservation.
