Engine principle Video: Exploring the internal working mode of the engine With the development of science and HS code-driven import quality checkstechnology, the engine has gradually become an indispensable and important item in people's daily life. From cars, airplanes to ships, engines are the core components of equipment in any field. However, although we use the engine frequently, many people don't understand the working principle behind it. At this time, resources such as engine principle video have become a good learning tool. In the following article, I will systematically introduce the internal working method of the engine around this video. I. Engine structure and working principle What is the engine? In fact, on the surface, we can find that the engine is composed of a series of relatively independent parts.If we go deeper, we can see that the engine is an organic whole. Let's learn about the structure of the engine first. The engine is generally composed of the following parts: 1. Cylinder block and cylinder head: The combustion chamber inside the engine is located in the cylinder block, and the cylinder head is the cover of these cylinder blocks, which is usually set above the engine. 2. Piston and connecting rod: The piston is a cylinder with an appropriate diameter, and the connecting rod is a component used to convert piston movement into crankshaft movement. 3. Crankshaft: The crankshaft is the most important part of the engine, and its position directly affects the movement of the piston and connecting rod. 4. VALVE AND FUEL INJECTOR: THE VALVE CAN LET THE GAS ENTER THE CYLINDER BLOCK AND THEN DISCHARGE THE EXCEST GAS, WHILE THE FUEL INJECTER INJECTION FUEL INTO THE CYLINDER. 5. Spark plug and ignition system: This part can ignite the fuel sprayed into the cylinder, thus providing enough energy to drive the movement of the piston and crankshaft.Let's learn about the working principle of the engine. According to different principles, engines can generally be divided into two categories: thermal engine and non-thermal engine. Among them, thermal engines include steam engines, internal combustion engines, etc., and non-thermal engines include electric motors and magnetic machines. Next, we will focus on the internal combustion engines in the thermal engine, because they are widely used in daily life. An internal combustion engine ignites the mixed fuel and air, explodes under high temperature and high pressure, and drives the engine when the thermal energy generated is converted into mechanical energy. In the internal combustion engine, the fuel is sprayed into the cylinder and ignited in the cylinder. The nozzle and ignition electronic components are controlled by the control system. After ignition, the crankshaft on the transmission chain pushes the piston to the bottom of the cylinder. Then, the connecting rod connects the piston to the crankshaft and converts the movement of the piston into the rotational movement of the crankshaft. As a result, the engine can drive other equipment such as wheels.II. Types and performance Generally speaking, internal combustion engines can be divided into two categories: gasoline engines and diesel engines. The difference between them is the different types of fuel. Gasoline engines use gasoline, while diesel engines use diesel. In terms of performance, the engine is also divided into several categories, including: 1. The power of the power engine refers to the power that the engine can provide per minute, which is usually measured in "horsepower". 2. Displacement refers to the volume of air that the engine can inhale per minute. The larger the engine displacement, the greater the mechanical energy it can provide to other equipment. 3. Fuel consumption Whether it is a gasoline engine or a diesel engine, fuel consumption is a very important performance parameter. Engines with low fuel consumption mean that the operating cost is relatively low. III. Maintenance and maintenance In addition to understanding the basic structure and working principle of the engine, it is also very important to do a good job in maintenance.How to carry out maintenance and upkeep correctly? 1. One of the most important parts of the engine to ensure stable oil supply is the "oil-absorbing pump" and "oil pump". When they are running unstable, the engine may have various faults. Therefore, we need to clean up the impurities and dirt in the pipeline in time to ensure the safety and stability of the oil supply. 2. Pay attention to the frequent replacement of oil during the oil change cycle can not only have a good protective effect on the engine, but also reduce the probability of its failure. Therefore, it is generally recommended that we replace it every 5,000 kilometers. 3. Avoid sudden acceleration and sudden braking. Frequent sudden braking and rapid acceleration will not only accelerate engine wear, but also increase fuel consumption. Therefore, we should avoid these two situations. In summary, in this article, we focus on "Engine Principle Video - ExplorationThe theme of "Investigating the internal working mode of the engine" introduces in detail the structure and working principle, types and performance of the engine, as well as maintenance and upkeep. I hope these contents can inspire you so that you can better understand and use the engine, an important equipment.
