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 runningσ 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 i§t 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 βengine. So how does the internal combustion engine work?

   The internal combustion engine is a power conversion system. It i★s a heat engine that chemically reacts (combustion) betwee n fuel and air in the system and converts the chemical energy (heat eneγrgy) released by the reaction into mechanical energy. This sentence does not seem to have m"any words, but it contains a lot of information. Because to complete this en ergy 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 o r more chemical substances. The chemical substances of internal combustion engines are fuel and ai'r. Fuels include liquid fuels (gasoline, diesel) and gaseous fuels (naπtural 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 be♦st to have a "person" to light the fire. This &£#034;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,γ the piston and the crank connecting rod mechanism are fixed to∑gether. 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 i≈s pressure, there will be resistance. The mixed gas b∞egins to heat up under high pressure and prepares to explod>e. At this moment, the ignition system is ready to release. A sparδk 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 αback, he was unwilling to come back and was beaten back. In this≈ way, the mixed gas is always put into the cylinder, the ignition bo¥dy is uniformly ignited, and the piston keeps reciprocating b☆ack 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 o•f the piston's labor into rotational motion and sends it to the c∏ar wheels. Therefore, the car looks elegant and calm on the surface, but there are many syst‍ems behind it to escort it.

   The neck height of the neck flange is low, which can imprεove the rigidity and load-bearing capacity of the ♣flange. Compared with the butt-welded flange, the welding workload isγ large, the electrode consumption is high, and it cannot withstand high temperature and ¥high pressure, repeated bending and temperature fluctu↔ations, but the on-site device is more convenient, and the process of welding seam scratching canγ 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 pre≤ssure of the pipeline, thereby reducing the high stress concentration in the fla nge base. Neck flange welding is a good design for butt welding those flanges thβat are provided due to their own constructive valuγe. However, the price is relatively high because of the complicated produc÷tion process of the product. Threaded (threaded) flange: The threaded flange is connected by t₽hreaded fasteners. But the center of the product has a thread size corresponding to the pipe. Itεs main advantage is that it can be assembled without welding. Sliding flange: Sliding flange has a> lower hub, because the pipe enters the single flang↓e before welding. This is to provide sufficient strength inside and ou tside 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 fl∏ange: in practice, the lap flange is the same complete sliding flange, unless i÷t 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 weld ing flange is a similar sliding flange, unless it has a hole and a co∏unter hole size. The matching of the counter hole and the pipe allows the pip>e to be inserted into a sliding flange similar to the flange. The diamete≠r of the smaller hole is matched with the same pipe with the sam≥e ID. The restriction is a built-in hole that stays a♦t the bottom as a shoulder sleeve designed for pipes. This eliminates any flow restriction♦s when using socket welding flanges.
  1. In order to compact the sealing surface of the flat welding€ flange, only a small pressure is required. As the required pr↑essure drops, the size of the bolts and the number required are c&orrespondingly reduced. After all, a plan is planned. A flat weld≤ing flange product with a relatively small volume and a relatively lig™ht weight.    2. The production of flat welded flanges can save data a§nd 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 wiβll be high, and the use of this flange can effectively save th♣e cost of materials. Conducive to construction, when connecting, the bolt holes of the f↑lange are inconvenient to align or to avoid replacing the flange bolt ho®les of the equipment, etc., the use of this flat welded flange is veγry 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 siz₹e of the compact flange is reduced is because The diameter of the seal is reduce d, which will reduce the cross-section of the sealing surface. Also, the flaφnge gasket has now been replaced by a sealing ring to↕ ensure an outstanding matching of the flat welded flange seal facing t>he sealing surface.    flat welding flange    But it also has some disadv antages:    Disadvantages of flat welding flange:   "The main design disadvantage of flat welded flanges is t☆hat it cannot ensure no leakage. This is the lack o¥f its planning: the connection is dynamic, and for example, the₽rmal expansion and fluctuating cyclic loads will cause move​ment 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 shortcom•ings, just try to control the lack of products to the minimum, so the company tries to perfect th≤e functions of the products when producing flat welded flanges to make th¶em play the greatest role.
      Flange work characteristics:   Flange work character←istics:    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 r±ange of butterfly valves;   2. The power supply is the driving energy of the∞ butterfly valve, with a wide range of power sources, wide applicatio♦n range, saving human resources, and having work efficiency;   3. Conveβnient operation and easy to meet various control requirements. It can be realized by selec✔ting different actuators, signal feedback, flow adjustment, explosion-proof an"d other functions;   4. Ultra-miniaturization can be realized, mechanicaπl self-locking can be realized, and different sealing rings can be changed to ↔meet different working conditions.   The working princi↕ple of flange:   Using the actuator to input a standard signal of 0-10 mA, the motor group drγives the gear, worm, and torque to drive the disc to rotate. When the valve is in the fully ope∑n 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: elasticγ 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 valv→e 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 valπves are required to be used as flow control, the main thing is to correctly select‌ the size and type of the valve.
 The valve is an accessory of the pipeline, used to control t♣he flow, pressure, and direction of the fluid. The fluid to be controlled ca≠n be liquid, gas, gas-liquid mixture or solid-liquid mixture.   one. Basi§c parameters of valve   The basic parameters of the valve include worki₹ng 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 teεmperature. 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 val ve, it can be divided into the following five types:  ☆ ①Shutoff valve    shut-off valve is also called clεosed-circuit valve, its function is to connect or ♠cut off the medium in the pipeline. Block valves include gate valves, globe valves, plug valv×es, ball valves, butterfly valves, and diaphragm valves.   ②Chec k valve    Check valve is also called one-way valve or check valve, its functio n is to prevent the back flow of the medium in the pipeline. For example, th∏e 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 th€e pipeline or device from exceeding the specified value to protect the safe opera‍tion of subsequent equipment.   ④Regulating valve   The function of th☆e regulating valve is to regulate the pressure, flow and other parameters of t≤he medium. The regulating valve has different classification m♣ethods. According to the purpose and function, the regulating valve can be divided into:  ε  (1) Two-position valve. The two-position valve i✘s mainly used to close or connect the medium.    (2) Regulat∞ing valve. The regulating valve is mainly used for regulating the coeff icient. When selecting the valve, the flow characteristics of tαhe regulating valve need to be determined; the reg∏ulating valve can be divided into the following forms according to the struc•ture: single-seat regulating valve; double-seat reg→ulating valve; sleeve regulating valve; angle regulating Valve; three-way reguφlating valve; diaphragm valve; butterfly valve; ball valv♥e; 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 diver₽ter valve includes various distribution valves and flow valves, etc., whose function is to distrib☆ute, 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 th≥at do not require external drive, but rely on the energy of the medium to ac>tuate the valve, such as safety valves, pressure reducin©g valves, traps, check valves, automatic control valves, etc.   ②Power₽ driven valve   The power-driven valve can be dri"ven by various power sources. Including electric valves driven by electricity, pneumatic $valves driven by compressed air, hydraulic valves driven by hydrau<lic pressure such as oil, and combinations of various driving methods, such© as pneumatic-electric valves.   ③Manual valve   Manual valves use handwheels, handles, ÷levers, sprockets and other components to manipulate the valveσ action by manpower. When the valve closing torque is large, a gear γor turbo reducer can be set between the handwheel and the valve stem​. If necessary, universal joints and drive shafts can also be used for ★long-distance operation.   3. Press the connection ∏method    can be divided into the following six types according to the connection method:   ①T$hreaded connection valve: The valve body has an internal threa♦d or an external thread to connect with the pipe thread;   ②Flange con'nection valve: the valve body has a flange to connect with the pipe≠line flange;   ③Welding connection valve: The valve≠ body has a welding groove and is welded to the pipe☆line;   ④Clamp-connected valve: the valve body has a clamp§ to connect with the pipe clamp;   ⑤ Card sleeve connection valve: It is connected with th©e pipeline by a card sleeve;   ⑥Wafer connection valve: a  connection form in which the valve and the two pipes are directly clamped toge↕ther with bolts.   4. According to the valve body material   ①Metal material valve   The val✔ve body and other parts are made of metal materials, suφch as cast iron valves, carbon steel valves, alloy steel va♥lves, copper alloy valves, aluminum alloy valves, lead alloy valves, titanium alloy valves,→ Monel alloy valves, etc.   ②Non-metallic valve   The va lve body and other parts are m
The caliper can also be called a brake cylinder. There are a lot of pistons inside the calip≈er. The function of the caliper is to push the brake pads to clamp the brake disc, soπ 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 vita↕l system in a car. The brake system is related to t>he 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 disc★s. Brake pads and brake discs are basically wearing parts that ©need to be replaced on a regular basis. As the driving distan$ce of the car increases, the brake pads and brake discs will basical↕ly continue to wear. After the brake pads and brake  discs are worn to a certain degree, they need to be replaced. If they aπre not replaced, the braking distance will be affected. After the driver  steps on the brake pedal, the master cylinder can push the brake cylinder through the‌ brake fluid. At this time, the brake cylinder can push the brake pads to clamp the brake ✔disc. The vacuum booster pump provides power assistance, and the vacuum booster pump allows✘ the driver to easily step on the brake pedal. The brake fluid in ↑the brake system needs to be replaced regularly. If it ‍is not replaced for a long time, it will affect the braking force an$d 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 replaceσd. After replacing the brake fluid, the air in the brake system pipeline needs to be empt₽ied, otherwise the braking force and braking distance may also be affected.
   We have seen many products using gears in our lives, but do you know what princip★le they use gears? According to its working principle,  ₹  gear has the following functions: First, gears can transmit mechanical power, such as automo↕bile gear shifting devices, industrial gearboxes, etc.; se×cond, gears can change the direction of movement, such as mechanical watche₩s, shaking head devices in electric fans, etc.; third, gears can reduce speed and Improve torque, s±uch as motor reducer, various speed change mechani♣sms, etc.   Gear transmission mechanism    Here are two interesting applications of  gears in automobiles and aviation, let's take a look at the role of gear∏s in them.    There is a mechanical structure in a car called a differ$ential, which is an extremely important part. When a car turns, the speeds of πthe inner and outer wheels are different. If there is no differential, the speeds of the inner and βouter wheels are the same. The wheels slip and roll over. Moreover, the speed of the car is ver♦y fast, and it is absolutely impossible to have no differential at σhigh speeds. The gear here is on the differential, which can ₽not only transmit the power of the engine, but als♣o 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 beca use of their excellent performance. This helicopter has tw o 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 reversa∏l structure, it can be seen that after two transformations of the φgear, the mechanical transmission direction is smoothly changed, and tw&o different rotation directions are realized on the☆ same shaft.
