What is pot wheel pressurization and what is double pot wheel pressurization

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

The main function of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine and making the car more powerful. When an engine is equipped with a turbocharger, its maximum power can be increased by 40% or more compared to without a turbocharger.

This means that the same engine can be boosted to put out more power. Take our most common turbocharged engine, for example, after supercharging, the power can reach the level of the engine, but the fuel consumption is not much higher than the engine.

A turbocharger (tubro) is actually an air compressor. It uses the exhaust gases from the engine as power to push the turbine in the turbine chamber (located in the exhaust duct), and the turbine drives the coaxial impeller to be located in the inlet duct? The impeller compresses the fresh air from the air filter duct and feeds it into the cylinder.

When the engine speed is accelerated, the exhaust gas discharge speed and the turbine speed are also accelerated, the degree of air compression can be increased, and the air intake of the engine will be increased accordingly, and the output power of the engine can be increased.

The biggest advantage of turbocharging is that it can greatly increase the power and torque of the engine without increasing the engine displacement. When an engine is equipped with a turbocharger, the maximum power output can be increased by about 40 or more compared to the unsupercharger.

The common turbocharging is single turbocharging, which is divided into mechanical turbocharging, exhaust gas turbocharging and composite turbocharging.

Mechanical supercharging is the engine running directly to drive the turbine, the advantage is that there is no turbo hysteresis, the disadvantage is that part of the power is lost, and the boost value is low.

Exhaust gas turbocharging is to rely on the remaining kinetic energy of the engine exhaust to drive the turbo spin, the advantage is that the turbo speed is high, the boost value is large, the power is obviously improved, the disadvantage is that there is turbo hysteresis, that is, the engine at a lower speed stool disadvantages (generally below 1500-1800 rpm) exhaust kinetic energy is small, can not drive the turbine to rotate at high speed to produce the effect of increasing the intake pressure, the engine power at this time is equivalent to natural aspiration, when the speed increases, the turbocharging plays a role The power will suddenly increase.

Twin turbocharging is for the exhaust gas turbo turbo turbo hysteresis phenomenon, increase the height quietly add a low-speed turbo, when the engine is low, less exhaust can drive the turbine to rotate at high speed to produce enough intake pressure, when the engine speed is increased, the high-speed turbo work continues to enter the state of high boost value, providing a coherent strong power.

That is, there are two turbochargers.

Reuse the exhaust gases from the engine! The exhaust gas is then output to the air intake and enters the combustion chamber together with fresh air for combustion, so that the speed of the air intake is fast and the pressure is high, which can increase the power and speed of the engine!

The exhaust gas is reused, and a part of the exhaust gas after combustion is transferred to the cylinder again to participate in combustion, so as to improve the utilization rate of combustible gas and play the effect of fuel saving and environmental protection.

The first turbochargers were used in sports cars or formula cars, so that in racing races where engine displacement was limited, the engine was able to get more power. As we all know, the engine relies on the fuel to do work in the cylinder to output power, and the amount of fuel input is limited by the amount of air drawn into the cylinder, so the power output of the engine will also be limited. If the engine is already running at its best, increasing the output can only increase the amount of fuel by compressing more air into the cylinders, thereby increasing the combustion function.

Therefore, under the existing technical conditions, the turbocharger is the only mechanical device that can increase the output power of the engine under the same working efficiency.

You may think that the turbocharger is very complicated, but it is not complicated, the turbocharger is mainly composed of a turbine chamber and a supercharger. The first is that the air intake in the turbine chamber is connected to the engine exhaust manifold, which in turn is connected to the exhaust pipe. Then the air intake of the supercharger is connected to the air filter duct, the exhaust port is connected to the air intake pipe, and finally the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are connected coaxially and rigidly.

That's a complete turbocharging unit, and your engine is "overclocked" like a computer CPU.

Generally speaking, turbocharging is the use of the exhaust gas inertia impulse discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, and the impeller compresses and transports the air from the air filter pipe to pressurize and enter the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, the pressure and density of the air increase can make more fuel fully combusted, increase the amount of fuel and adjust the speed of the engine, you can increase the output power of the engine.

The turbocharger of the car is mounted on the engine.

Turbocharging device is actually a kind of air compressor, through the compression of air to increase the air intake of the engine, in general, turbocharging is the use of the engine exhaust gas inertia impulse to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller compresses and transports the air from the air filter pipeline, so that it enters the cylinder after pressurization. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, the pressure and density of the air increase can make more fuel fully combusted, increase the amount of fuel and adjust the speed of the engine, you can increase the output power of the engine.

on the intake and exhaust manifolds. The working principle is to let the incomplete gas circulate and burn again, and the size of the throttle is controlled, and generally the large throttle starts to work.

The intake port in the turbine chamber is connected to the engine exhaust manifold, which in turn is connected to the exhaust pipe. Then the air inlet of the supercharger is connected with the air filter pipeline, the exhaust port is connected to the intake manifold, and finally the turbine and the impeller are installed in the turbine chamber and the supercharger respectively, and the two are coaxial rigid connection The principle is: the turbine in the turbine chamber is driven by the exhaust gas inertia impulse discharged by the engine, and the turbine drives the coaxial impeller again, and the impeller pressurizes the air sent by the air filter pipe to pressurize it into the cylinder.

When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and the pressure and density of the air increase can burn more fuel.

Name implies.. It is a device for car pressurization and air intake! It is to increase the air intake!
