Disassembly of car parts engine (disassembly of parts and Carbon steel HS code referencesfunction analysis of automobile engines) Car engines is one of the core components of modern vehicles. Its complex structure and high performance enable us to drive the car on the road unimpeded. . However, the internal parts of the engine and their functions are still a mysterious field in the eyes of most people. This article will show readers the internal structure of the engine and its working principle by disassembling and analyzing the parts and functions of the automobile engine, combined with actual cases.I. The basic structure and working principle of automobile engine Automobile engine is a device that converts fuel combustion into mechanical power. Usually, the structure of the automobile engine is relatively stable, mainly including the main components of the intake system, fuel supply system, ignition system, cylinder and crankshaft, connecting rod, piston and valve mechanism, cooling system, lubrication system and exhaust system. The various parts inside the engine work together to generate power, thus driving the car. The working principle of the engine can be briefly described as the following process: 1. The fuel enters the combustion chamber and mixes with the air entering the cylinder. At the same time, the piston in the cylinder began to move down, so that the mixed gas was compressed. Two. When the piston reaches the bottom, the ignition system triggers an explosion of the mixed gas, which will generate heat energy to expand outward with the surrounding gas.3. The inflated gas pushes the piston upwards, and then drives the crankshaft. Four. The crankshaft converts the movement of the piston into rotation through the connecting rod mechanism, generating the corresponding mechanical power. 5. The mechanical power drives the tires and flips the vehicle through the transmission system. II. Parts of automobile engines and their functions 1. Piston piston is one of the keys of the engine. Its main function is to convert the original energy of combustion and explosion into mechanical force. When the piston moves up and down, it compresses and sucks in the gas in the combustion chamber, and then relaxes and expands. Further adjust the linear movement of the piston by pushing the connecting rod. The bulge at the bottom is to transform the movement of the piston into the power to rotate the crankshaft. Two. The crankshaft of the automobile engine is an important part that transforms the up and down movement of the cylinder piston into mechanical power. Its main designThe purpose is to provide support for the power caused by the piston, which is one of the main movement components of the engine. The crankshaft movement is carried out on a vertical plane and converted into a single-axis rotational motion through the connecting rod. 3. Lubrication system The lubrication system of automobile engines can provide the engine with the necessary oil pressure and oil film to supplement the lubrication and cooling, thereby reducing the heat and wear of the parts. The design of the engine will maintain a layer of oil film on the sliding surface to form an isolation between the two layers and reduce friction. This process is usually initiated by the crankshaft connected to the spacer ring and the spindle. The oil circulates in the engine, is absorbed from the oil sap pump, and then circulates after entering the engine through the oil filter, and forms an oil film between the lubrication and cooling parts. With the accumulation of impurities, the suction and pressure of the oil span pump are reduced and output to filter paper containing impurities, while reducing fuel economy and reliability.Four. The air intake system The intake system must have a certain flow rate in the car engine, which can ensure that the fuel and air reach the appropriate proportion. The air intake system mainly includes air intake, air filter, air intake pipe, air intake tube throat and throttle valve. 5. Ignition system The ignition system mixes fuel with oxygen through electrical energy, and then ignites it in the cylinder to achieve the effect of combustion. Ignition systems usually include ignition coils, ignition switches, ignition telephones, spark plugs (or high-voltage wires and spark plugs integration), etc. 6. The cooling system engine will generate a large amount of heat during its operation. If there is no reasonable heat dispersion mechanism, the engine will overheat and burn out. The main function of the cooling system is to keep the engine in the ideal temperature range and reduce the wear of the components through the water tank and coolant.The cooling system is usually composed of a water pump, a water tank, a hydraulic control valve, a thermometer and a liquid flow meter. The liquid flows through the coolant channel of the pump and the engine to absorb the heat generated in the engine and bring the heat to the air at the front of the car to radiate and dissipate heat. 7. The main function of the exhaust system of the exhaust system engine is to convert thermal kinetic energy into mechanical power and discharge the exhaust gas of the document. The exhaust system usually includes silencers, exhaust pipes, exhaust manifolds and exhaust valves, etc. The exhaust gas of the engine will enter the exhaust manifold through the exhaust valve and be discharged through the silencer. The conclusion is a brief introduction to the disassembly of automobile engines, parts and their working principles. For many people, car engines are still a relatively esoteric field. In addition to the basic knowledge required in repair and maintenance,A deeper understanding of car engines will help you understand the working principle of cars and master the knowledge of safe driving.
