Engine analysis diagram (automotive engine component analysis diagram,Pharma cold chain HS code analysis showing the engine structure in detail.) The engine of a car is one of its most important components, because it provides power for the car. The main task of the engine is to burn the mixture of fuel and air into energy and drive the wheels to rotate. Different parts of the engine have different functions, and they work together to make the engine run efficiently. This article will introduce the analysis diagram of automobile engine parts in detail to better understand the engine structure. 1. The core component of the cylinder block engine is the cylinder block, which is usually made of cast iron or aluminum. The cylinder block is composed of several cylinders, each of which has a piston. The combustion chamber is located inside the cylinder block, in which the fuel is ignited to generate energy. As the engine runs, the cylinder block discharges steam and flue gas from the engine. Two. The piston piston is a machine part that cooperates with the cylinder. It moves in the cylinder and is under the pressure of a mixture of fuel and air.Each cylinder of the engine has a piston, which moves up and down in the combustion chamber. When the fuel is ignited, the piston moves down while compressing the air and the fuel mixture. If the engine is a four-stroke engine, the piston is also responsible for pushing the exhaust gas upwards. 3. The crankshaft is another core component of the engine, which converts the movement of the piston into rotational motion. The crankshaft consists of multiple connecting rods, which are connected to each piston of the engine. As the piston rises and falls, the connecting rod is stretched and compressed to transfer the movement to the crankshaft. The torsional motion of the crankshaft changes the linear motion of the piston, transferring energy to the transmission system and the drive wheel. Four. The valve is an important part of the internal combustion process of the engine. Through the valve, the engine can control the fuel and air into and out of the cylinder block. The valve is controlled by the transmission mechanism, which is connected to the camshaft.As the camshaft rotates, the valve opens or closes. This design can accurately control the mixture in the combustion chamber, so as to achieve efficient and economical combustion. 5. Spark plug Spark plug is a small part placed in the cylinder block of a car engine. Its main function is to ignite a mixture of fuel and air, thus causing an explosion and generating energy. Each cylinder has a spark plug to ensure that all fuel and air mixtures are ignited. Regular replacement of spark plugs can ensure that the engine is always in the best condition. 6. The intake pipe is a pipe connecting the engine and the air filter. Its function is to introduce air into the combustion chamber of the engine and mix it with fuel for combustion. The air intake pipe can also play a role in sound insulation and shock absorption, which is very important for reducing noise and improving driving comfort.7. Exhaust pipe is another important part of the engine. Its function is to exhaust the engine gas from the vehicle and introduce it into the exhaust system. The exhaust pipe can also play a role in sound insulation and shock absorption, which is very important for reducing noise and improving driving comfort. In addition, the catalyst in the exhaust pipe can filter the harmful substances in the exhaust. In a word, the analysis diagram of automobile engine parts is a good way to gain an in-depth understanding of the engine structure. Each part of the engine plays an indispensable role, and reasonable cooperation can make the engine run efficiently. Car owners can better understand car engines based on these knowledge and carry out timely repair and maintenance.
