What is the working principle of turbocharged engine?What is a turbine? What's the matter with supercharging? _Baidu...

When the gas of the exhaust pipe is discharged, the gas will drive the turbine to rotate. The turbine rotation of the exhaust pipe will drive the turbine of the intake pipe through the connecting rod, so the turbine of the intake pipe will push the air to accelerate into the cylinder, so that the intake process of the cylinder is no longer simply using air pressure. The intake volume has also increased greatly.

The working principle of the turbine is: a special compressor is used to compress the gas in advance before entering the cylinder, so as to improve the gas density entering the cylinder and reduce the volume of the gas. In this way, the mass of the gas is greatly increased in the unit volume, and the intake can meet the combustion needs of the fuel, so as to reach To the purpose of improving the engine power.

Turbocharging is a technology that uses the exhaust gas generated by the operation of the internal combustion engine to drive the air compressor.

What is the difference between a steam turbine and a flattening machine?

1. The working quality of the permeable machine can be gases, such as steam, gas (gas turbine), air and other gases or mixed gases, or liquids, such as water (water turbine), oil or other liquids. The quality of the turbine can only be steam, so it is also known as steam leveling machine.That is to say, the turbine is a permeable flat machine.

2. The cooling method of gas permeable and turbine and permeable blades is: the gas permeable blades are all hollow structures, and PCD air is introduced into the flow channel formed by the hollow blades to achieve the purpose of cooling.

3. Toping is the transliteration of English turbine, which translates as steam turbine.

Who designed the most efficient steam engine? What's the name? Not the inventor.

1. There are many kinds of steam engines, but at present, the most efficient steam engine is the steam turbine. Its full name is Steam turbine, which is a machine that converts the kinetic energy of water vapor (formed by heating water) into the kinetic energy of turbine rotation. .

2. Watt is not the inventor of the steam engine. Before him, the steam engine, that is, the Newcomen steam engine, appeared long ago, but it consumed a lot of coal and had low efficiency. Using scientific theory, Watt gradually discovered the problem of this steam engine.

3. He is Watt, the inventor of the steam engine. Some people once said that Watt invented the steam engine because he had superhuman genius and wisdom. Actually, it's not. In order to explain this problem, let's tell the story of Watt's diligent study, hard study; invention and creation.

4. The world's first steam engine was invented by the ancient Greek mathematician Hiro of Alexandria in the 1st century AD, which is the rudiment of the steam engine. In about 1679, the French physicist Dennis Papin made the working model of the first steam engine after observing the steam escape from his pressure cooker.

5. James Watt, a Scottish inventor, is often known as the inventor of the steam engine and is a key figure in the industrial revolution. In fact, Watt was not the first person to invent the steam engine. In the first century AD, Alexander Hiro designed a similar machine.

The principle of turbo engine

1. The principle of turbocharged engine: When the driver steps on the accelerator, the engine speed changes. Due to the inertia of turbines and compressors, they cannot keep up with the change of this speed in time. This phenomenon is called "slugging phenomenon" and "lagging phenomenon" that delays the engine to increase or decrease the output power.

2. The second type increases the speed of the engine by increasing the speed of the engine, it can also increase the output power of the engine, and the increase in speed is the number of ignitions per unit time of the engine. If the engine is ignited more times per unit of time, the output power of the engine will undoubtedly increase, but due to mechanical stability.

3. The working principle of turbocharging is that the exhaust gas enters the turbine housing through the exhaust manifold to promote the turbine rotation. Because the turbine and the impeller are co-axes, the impeller in the other side of the housing also rotates with the turbine. The impeller compresses the air and sends the high-density compressed air into the combustion chamber to participate in the combustion.

4. Basically, it evolved from the principle of turbofan engine, but the latter turns the fan into a propeller, while the former turns the fan into a helicopter rotor.

5. Turbocharging is mainly beneficialUse the energy of the engine exhaust to drive the compressor to achieve the supercharging of the intake. The whole process basically does not consume the power of the engine and has good acceleration sustainability. However, the turbine cannot intervene in time at low speed, which has a certain lag.

What is the principle of the turbine engine?

1. The turbine system is one of the most common supercharged systems in supercharged engines.

2. The working principle of the four-stroke engine is to realize the process of intake and exhaust through the switch of the intake control valve and the exhaust control valve. Control the time point of gas combustion by controlling the spark plug to ignite. Then through the ECU, the intake, exhaust and combustion are organically combined in order, and the engine can achieve normal operation.

3. The working principle of the turbine is: a special compressor is used to compress the gas in advance before entering the cylinder to improve the density of the gas entering the cylinder and reduce the volume of the gas. In this way, the mass of the gas is greatly increased in the unit volume, and the intake of air can meet the combustion needs of the fuel, from And to achieve the purpose of improving the engine power.
