  • Principle of gasoline engine (brief analysis of the working principle of gasoline engine) Gasoline engine is Pharma active ingredients HS code checksan internal combustion engine, which uses flammabilityLiquid fuel - gasoline is used as fuel and burned internally to produce heat energy, which is further converted into mechanical energy to drive the car. In order to better understand the working principle of gasoline engines, it is necessary to analyze its structure and working process. I. Gasoline engine structure (1) Cylinder, piston and crankshaft The core components of gasoline engine are cylinder, piston and crankshaft. The cylinder is a long tubular structure inside the engine, which is cast from high-strength alloy. Generally, there are multiple cylinders inside the engine. The piston is a moving part in the cylinder, which is made of light alloy or aluminum. The piston is connected to the crankshaft through the connecting rod, and the cylinder rotates with the up and down movement of the piston, and the crankshaft also rotates. ( II) Intake and exhaust pipes. Gasoline engines need gas in and out, so intake and exhaust pipes are needed to complete this process.The intake pipe introduces air into the cylinder and adds it to the oil mixture for combustion. The exhaust pipe discharges the exhaust gas to the outside world. ( III) Ignition system The ignition system is an important part of the mixture to ignite and burn. Its core part is the ignition plug, which is made of metal and ceramics to guide the high-voltage arc to ignite the oil mixture. II. Working principle of gasoline engine The working principle of gasoline engine can be divided into four-stroke cycle and two-stroke cycle according to different power cycles. As the name implies, the four-stroke cycle is divided into four steps: intake, compression, combustion and exhaust. 1. Inhalation process: The piston moves from top to bottom, showing a trend of linear movement, inhaling fresh mixed gas inside and outside the cylinder, and the piston at the entranceWhen the valve is close to the lower stop point, the mixed gas is concentrated into the cylinder. Because the piston is still retained at the lower stop point, the mixed gas added to it will be objectively compressed. 2. Compression process: The piston begins to move towards the top of the cylinder. Friction produces heat, and compression compresses the mixture into a smaller space, which compresses the gas in the mixture, thus raising the temperature of the mixture. 3. Ignition combustion process: When the piston is extremely close to the upper dead point, the ignition plug activates the mixture that has been ignited, generating sparks and burning the mixture, so that the gas can release a large amount of energy. The flame expands in the cylinder, pushing the piston to move from the initial position. At the same time, the combustion of gasoline will release exhaust gas and generate pressure to promote the movement of the cylinder. 4. Exhaust process: when gasoline is completely burnedNext, the piston moves downwards. When moving, it discharges the burned exhaust gas, discharges the cylinder, and discharges it out through the exhaust pipe under the control of the displacement gate. As the name implies, the two-stroke cycle has only two-strokes, which include the processes of intake and compression, combustion and exhaust in one stroke. Although such a simple structure, its efficiency is slightly lower than that of the four-stroke cycle. Summary The gasoline engine converts the mixture in a series of transformations and chemical energy into mechanical energy through the cycle of four strokes. Therefore, the above analysis and understanding of the principle of gasoline engines are crucial for the maintenance of cars. Maintaining a suitable engine working level can not only ensure the safety and performance of the car, but also save fuel and related costs.
