Oil engine: the core of the driving power source. The HS code-based invoice validationoil engine is an engine that uses fuel as the power source. It is the core of cars, airplanes and other means of transportation, providing powerful power for these machines to run quickly. Nowadays, oil engines have become one of the essential basic equipment in our production life, but few people know its history and principle. The history of oil engines The history of oil engines can be traced back to the end of the 19th century.At that time, automobile and aircraft manufacturers tried to use burning fuel to promote the development of machines. Due to factors such as times and technology, it was difficult to find the perfect power source. Finally, the oil engine was born. The basic principle is: mix oil and air, click the mixture of fuel, generate sparks and energy, and then convert sparks and energy into mechanical energy to promote the operation of the machine. At that time, the earliest oil engines lacked safety and reliability in this regard, and many people were worried that fuel combustion would cause explosions or fires. However, this did not stop the development of oil engines. After many failed attempts, oil engines were finally established and became an important power source for all vehicles. The principle of oil engine The basic principle of oil engine is thermodynamic spontaneous response. By mixing fuel and oxygenThen ignite the mixture to cause combustion, and the thermal energy and pressure energy generated by the flame are converted into mechanical energy. The working principle of the oil engine can be summarized as the following steps: 1. Air intake: Fuel and air are mixed at the engine intake valve to form a fuel mixture. The intake valve can also control the amount of fuel and air required for the oil engine. Two. Compression: The fuel mixture is compressed and the energy is concentrated in a small area to facilitate ignition and combustion. 3. Ignition: The igniter ignites the fuel mixture and burns the gas that produces sparks and high temperatures. Four. Explosion: These ignited substances diffuse sparks and high-temperature energy into the volume of the engine, thus generating explosive energy, and the pressure generated by this energy can drive the piston movement. 5. Exhaust: The exhaust door is opened to discharge the exhaust gas from the engine to prepare for the next cycle.Characteristics of oil engines As one of the most mature power sources at present, oil engines are not as innovative as electric motors in terms of machinery. However, in most cases, oil engines are still the first choice. The main reasons are as follows: 1. High power: Oil engines can provide enough power to drive labor and large machinery and equipment. Two. Long life: Although the technology of other power sources is constantly upgrading, the oil engine is still highly sustainable and can provide long-term stable power support for the machine. 3. Strong adaptability: Oil engines can use various fuels and can be specially designed to adapt to different types and sizes of machines. In a word, oil engines are still important basic equipment in our production and life. Now, with the improvement of technology and people's awareness of environmental protection and sustainability, many new power sources are being developed, and these power sources will also provide us with new options in the future. But in any case, as an indispensable part of our production life, the value and significance of oil engines will never be out of date.
