The working principle of the internal combustion engine of the car engine

(Summary description)We all know that a car can't walk without gas, and start running again after adding gas, but have you ever thought about why this is? How does it turn gasoline into a steady stream of power? Is it digested and absorbed by the stomach like a human?

　　 The reason why a car can run is because it has a heart, an engine. Like the human heart, it continuously outputs power to make cars run wild. The engine is also called the engine, and the scientific name is the internal combustion engine. So how does the internal combustion engine work?

　　 The internal combustion engine is a power conversion system. It is a heat engine that chemically reacts (combustion) between fuel and air in the system and converts the chemical energy (heat energy) released by the reaction into mechanical energy. This sentence does not seem to have many words, but it contains a lot of information. Because to complete this energy conversion, at least the following conditions must be met:

　　 One, fuel supply system

　　 2. Gas distribution system

　　 Three, ignition system

　　 Four, crank connecting rod mechanism

　　 5. Lubrication system

　　 Six, cooling system

　　 Seven, start the system

　　 First of all, to produce a chemical reaction, there must be two or more chemical substances. The chemical substances of internal combustion engines are fuel and air. Fuels include liquid fuels (gasoline, diesel) and gaseous fuels (natural gas). With chemical substances, there are also chemical reaction conditions. The chemical conditions for fuel combustion are of course high temperature and high pressure. It is best to have a "person" to light the fire. This "person" is the ignition system.

The reaction starts when all the reaction conditions are met. The specific process is as follows: the fuel supply system and the air distribution system put the fuel and air into a closed container (cylinder) at a set ratio according to the instructions of the control computer. The movable piston, the piston and the crank connecting rod mechanism are fixed together. When the mixed gas of fuel and air enters the cylinder, the crank-connecting rod mechanism leads the piston to start compressing the mixed gas. Where there is pressure, there will be resistance. The mixed gas begins to heat up under high pressure and prepares to explode. At this moment, the ignition system is ready to release. A spark came out, instantly igniting the mixed gas. The volume of the ignited mixed gas instantly expanded, and the piston couldn't resist it and retreated. After going back, he was unwilling to come back and was beaten back. In this way, the mixed gas is always put into the cylinder, the ignition body is uniformly ignited, and the piston keeps reciprocating back and forth. It looks so boring, however, it comes cleverly:

　　 It turns out that the crank and connecting rod mechanism secretly converts all the fruits of the piston's labor into rotational motion and sends it to the car wheels. Therefore, the car looks elegant and calm on the surface, but there are many systems behind it to escort it.

Talking about the welding technology of neck flange [ 2021-08-13 ]
　　 The neck height of the neck flange is low, which can improve the rigidity and load-bearing capacity of the flange. Compared with the butt-welded flange, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations, but the on-site device is more convenient, and the process of welding seam scratching can be omitted, which is more popular. Butt welding flange with neck: neck flange welding is usually called "high hub" flange. Its purpose is to transfer the pressure of the pipeline, thereby reducing the high stress concentration in the flange base. Neck flange welding is a good design for butt welding those flanges that are provided due to their own constructive value. However, the price is relatively high because of the complicated production process of the product. Threaded (threaded) flange: The threaded flange is connected by threaded fasteners. But the center of the product has a thread size corresponding to the pipe. Its main advantage is that it can be assembled without welding. Sliding flange: Sliding flange has a lower hub, because the pipe enters the single flange before welding. This is to provide sufficient strength inside and outside the welding to avoid leakage. Sliding flanges are matched with boring pipes with slightly larger outer diameters. They are better than neck flange welding due to lower initial cost. flange Many users, but the cost of the latter device will not be low, due to the increase in the number of weld neck flanges, lap flange: in practice, the lap flange is the same complete sliding flange, unless it is in the hole and A radius between flange races. It is necessary for the radius to have the flange to contain the lap stub to complete. Usually, the lap flange and the lap stub end mating together will assemble the system. The socket welding flange is a similar sliding flange, unless it has a hole and a counter hole size. The matching of the counter hole and the pipe allows the pipe to be inserted into a sliding flange similar to the flange. The diameter of the smaller hole is matched with the same pipe with the same ID. The restriction is a built-in hole that stays at the bottom as a shoulder sleeve designed for pipes. This eliminates any flow restrictions when using socket welding flanges.
Advantages of flat welding flange [ 2021-08-13 ]
　　1. In order to compact the sealing surface of the flat welding flange, only a small pressure is required. As the required pressure drops, the size of the bolts and the number required are correspondingly reduced. After all, a plan is planned. A flat welding flange product with a relatively small volume and a relatively light weight. 　　 2. The production of flat welded flanges can save data and reduce costs. When the raw material of the pipe is special and the price is high, the cost of welding the flange of the same raw material will be high, and the use of this flange can effectively save the cost of materials. Conducive to construction, when connecting, the bolt holes of the flange are inconvenient to align or to avoid replacing the flange bolt holes of the equipment, etc., the use of this flat welded flange is very suitable.         3. The flat welding flange can save space and reduce weight in the process of use. The most important thing is to ensure that the head part will not leak. It has a very outstanding sealing function. The reason why the size of the compact flange is reduced is because The diameter of the seal is reduced, which will reduce the cross-section of the sealing surface. Also, the flange gasket has now been replaced by a sealing ring to ensure an outstanding matching of the flat welded flange seal facing the sealing surface. 　　 flat welding flange 　　 But it also has some disadvantages: 　　 Disadvantages of flat welding flange: 　　The main design disadvantage of flat welded flanges is that it cannot ensure no leakage. This is the lack of its planning: the connection is dynamic, and for example, thermal expansion and fluctuating cyclic loads will cause movement between the flange surfaces, which will affect the function of the flange, which will damage the integrity of the flange and eventually lead to leakage. It is impossible for any product to be without shortcomings, just try to control the lack of products to the minimum, so the company tries to perfect the functions of the products when producing flat welded flanges to make them play the greatest role.
The principle and characteristics of the use of flanges [ 2021-08-13 ]
      Flange work characteristics: 　　Flange work characteristics: 　　 1. A self-control butterfly valve that can be remotely controlled, which also has the characteristics of a flanged butterfly valve, and can be equipped with a wide range of butterfly valves; 　　2. The power supply is the driving energy of the butterfly valve, with a wide range of power sources, wide application range, saving human resources, and having work efficiency; 　　3. Convenient operation and easy to meet various control requirements. It can be realized by selecting different actuators, signal feedback, flow adjustment, explosion-proof and other functions; 　　4. Ultra-miniaturization can be realized, mechanical self-locking can be realized, and different sealing rings can be changed to meet different working conditions. 　　The working principle of flange: 　　Using the actuator to input a standard signal of 0-10 mA, the motor group drives the gear, worm, and torque to drive the disc to rotate. When the valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. 　　Butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. The valve with metal seal generally has a longer life than the valve with elastic seal, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the defect of temperature limitation. If flanged butterfly valves are required to be used as flow control, the main thing is to correctly select the size and type of the valve.
The role and use of the valve [ 2021-08-13 ]
　The valve is an accessory of the pipeline, used to control the flow, pressure, and direction of the fluid. The fluid to be controlled can be liquid, gas, gas-liquid mixture or solid-liquid mixture.   one. Basic parameters of valve 　　The basic parameters of the valve include working pressure (PN), working temperature (T) and nominal diameter (DN). For various valves equipped on pipelines, nominal pressure and nominal diameter are commonly used as basic parameters. Nominal pressure refers to the maximum working pressure that a valve of a certain material can withstand at a specified temperature. The nominal diameter refers to the nominal inner diameter of the connecting end of the valve body and the pipeline. Valves, pipelines and pipeline accessories of the same nominal diameter can be connected to each other, which is interchangeable.   two. Valve classification 　　 1. According to function and purpose 　　 According to the different functions of the valve, it can be divided into the following five types: 　　①Shutoff valve 　　 shut-off valve is also called closed-circuit valve, its function is to connect or cut off the medium in the pipeline. Block valves include gate valves, globe valves, plug valves, ball valves, butterfly valves, and diaphragm valves. 　　②Check valve 　　 Check valve is also called one-way valve or check valve, its function is to prevent the back flow of the medium in the pipeline. For example, the suction valve of the water pump belongs to the non-return valve category. 　　③Safety valve 　　 The role of safety valves is to prevent the pressure of the medium in the pipeline or device from exceeding the specified value to protect the safe operation of subsequent equipment. 　　④Regulating valve 　　The function of the regulating valve is to regulate the pressure, flow and other parameters of the medium. The regulating valve has different classification methods. According to the purpose and function, the regulating valve can be divided into: 　　 (1) Two-position valve. The two-position valve is mainly used to close or connect the medium. 　　 (2) Regulating valve. The regulating valve is mainly used for regulating the coefficient. When selecting the valve, the flow characteristics of the regulating valve need to be determined; the regulating valve can be divided into the following forms according to the structure: single-seat regulating valve; double-seat regulating valve; sleeve regulating valve; angle regulating Valve; three-way regulating valve; diaphragm valve; butterfly valve; ball valve; eccentric rotary valve. 　　 (3) Shut-off valve. Usually refers to a valve with a leakage rate of less than one part in 100,000. 　　⑤Divert valve 　　 The diverter valve includes various distribution valves and flow valves, etc., whose function is to distribute, separate or mix the medium in the pipeline. 　　2. According to the valve drive mode 　　According to the valve drive mode, it can be divided into the following three types: 　　①Automatic valve 　　 refers to valves that do not require external drive, but rely on the energy of the medium to actuate the valve, such as safety valves, pressure reducing valves, traps, check valves, automatic control valves, etc. 　　②Power driven valve 　　The power-driven valve can be driven by various power sources. Including electric valves driven by electricity, pneumatic valves driven by compressed air, hydraulic valves driven by hydraulic pressure such as oil, and combinations of various driving methods, such as pneumatic-electric valves. 　　③Manual valve 　　Manual valves use handwheels, handles, levers, sprockets and other components to manipulate the valve action by manpower. When the valve closing torque is large, a gear or turbo reducer can be set between the handwheel and the valve stem. If necessary, universal joints and drive shafts can also be used for long-distance operation. 　　3. Press the connection method 　　 can be divided into the following six types according to the connection method: 　　①Threaded connection valve: The valve body has an internal thread or an external thread to connect with the pipe thread; 　　②Flange connection valve: the valve body has a flange to connect with the pipeline flange; 　　③Welding connection valve: The valve body has a welding groove and is welded to the pipeline; 　　④Clamp-connected valve: the valve body has a clamp to connect with the pipe clamp; 　　⑤ Card sleeve connection valve: It is connected with the pipeline by a card sleeve; 　　⑥Wafer connection valve: a connection form in which the valve and the two pipes are directly clamped together with bolts. 　　4. According to the valve body material 　　①Metal material valve 　　The valve body and other parts are made of metal materials, such as cast iron valves, carbon steel valves, alloy steel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, titanium alloy valves, Monel alloy valves, etc. 　　②Non-metallic valve 　　The valve body and other parts are m
What is the role of calipers [ 2021-08-13 ]
The caliper can also be called a brake cylinder. There are a lot of pistons inside the caliper. The function of the caliper is to push the brake pads to clamp the brake disc, so that the car can slow down. After the brake pads clamp the brake disc, the kinetic energy can be converted into heat energy. The brake system is a vital system in a car. The brake system is related to the driving stability and driving safety factor of the car. The key components of the brake system include vacuum booster pump, brake master cylinder, brake cylinder, brake pads, and brake discs. Brake pads and brake discs are basically wearing parts that need to be replaced on a regular basis. As the driving distance of the car increases, the brake pads and brake discs will basically continue to wear. After the brake pads and brake discs are worn to a certain degree, they need to be replaced. If they are not replaced, the braking distance will be affected. After the driver steps on the brake pedal, the master cylinder can push the brake cylinder through the brake fluid. At this time, the brake cylinder can push the brake pads to clamp the brake disc. The vacuum booster pump provides power assistance, and the vacuum booster pump allows the driver to easily step on the brake pedal. The brake fluid in the brake system needs to be replaced regularly. If it is not replaced for a long time, it will affect the braking force and braking distance. Brake fluid is a kind of fluid that is easier to absorb water. When the water content of the brake fluid reaches 3%, it needs to be replaced. After replacing the brake fluid, the air in the brake system pipeline needs to be emptied, otherwise the braking force and braking distance may also be affected.
What are the functions of gears [ 2021-08-13 ]
　　 We have seen many products using gears in our lives, but do you know what principle they use gears? According to its working principle, 　　 gear has the following functions: First, gears can transmit mechanical power, such as automobile gear shifting devices, industrial gearboxes, etc.; second, gears can change the direction of movement, such as mechanical watches, shaking head devices in electric fans, etc.; third, gears can reduce speed and Improve torque, such as motor reducer, various speed change mechanisms, etc. 　　Gear transmission mechanism 　　 Here are two interesting applications of gears in automobiles and aviation, let's take a look at the role of gears in them. 　　 There is a mechanical structure in a car called a differential, which is an extremely important part. When a car turns, the speeds of the inner and outer wheels are different. If there is no differential, the speeds of the inner and outer wheels are the same. The wheels slip and roll over. Moreover, the speed of the car is very fast, and it is absolutely impossible to have no differential at high speeds. The gear here is on the differential, which can not only transmit the power of the engine, but also reduce the speed through the different speed ratios of the gear device, and at the same time can achieve a very cool "differential" function. 　　 three-dimensional model of differential 　　In aviation, helicopters using coaxial reversal technology are favored by many countries because of their excellent performance. This helicopter has two propellers on the same shaft. When the plane is flying, the rotation direction of the two propellers must be opposite to ensure the power balance of the plane. 　　Helicopter using coaxial reversal technology 　　 From the three-dimensional model of the coaxial reversal structure, it can be seen that after two transformations of the gear, the mechanical transmission direction is smoothly changed, and two different rotation directions are realized on the same shaft.
