Help explain turbocharging? Who knows what turbocharging is all about

Hello, turbocharging is actually an air compressor. In order to increase the output of the engine. On the premise of not changing the cylinder capacity of the engine, the only way to increase the compression ratio of the air entering the cylinder is to increase the engine.

The purpose of the motor output power is to use the engine exhaust gas discharged from the engine exhaust port as the power to push the impeller in the turbine room. At the same time, the impeller is directly connected to the booster wheel in the pressurization chamber. The pressurization chamber was connected to the air at one end.

The other end presses air from the west into the engine's cylinders. The purpose of increasing the air in the engine has been achieved.

The first thing to be clear about is that the turbocharging system works using the exhaust gases of the engine. If you don't use it, it's a waste to get the exhaust fumes out in vain. (From this point of view, I don't see the economy of stopping or restricting the use of turbocharging) and if you think about it from a control point of view, adding a controller with or without turbocharging is not conducive to the structure of turbocharging (since it is supercharging, of course, the fewer interfaces, the better.

Reduce the rate of air leakage).

As for the disadvantages of turbocharging, it should be the response speed of turbocharging to the throttle should be the reason for the working principle. Pressing the accelerator hard, first the fuel is injected into the engine, and then the car accelerates forward. Fertilizer its discharge, pushing the turbine.

So turbocharging has to be a bit more unresponsive. The same problem arises with the throttle closed (not taking into account the brakes).

In a similar situation, it is said that the industry is now overcoming it by increasing the machining accuracy of the compression chamber and adopting new materials such as ceramics.

The problem with turbocharging is that the operating environment of turbocharging is extremely harsh. It's about 700 degrees Celsius. At the same time, the maximum drilling speed of the turbine is said to reach 8-100,000 rpm.

So the problem is the bearing on the turbine. That is, the bearing on the fan blade that is pushed by exhaust gas. Hope.

If you see a turbo or T at the rear of a car, it means that the engine used in the car is turbocharged.

A turbocharger is actually an air compressor that compresses air to increase air intake. It uses the inertia impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the impeller back to the shaft, and the impeller pressurizes the air sent by the air filter pipe to pressurize it into the cylinder.

The biggest advantage of the turbocharger is that it can greatly increase the power and torque of the engine without increasing the engine displacement.

First, let's figure out what turbocharging is. Generally speaking, if we see Turbo or T at the rear of the car, it means that the engine used in the car is turbocharged. I believe you have seen a lot of such models on the road, such as Audi A6, Passat, Bora.

Help explain that turbocharging doesn't invite anyone else to this problem, right?

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 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.

You may think that the turbocharging device is very complicated, but it is not complicated, the turbocharging device 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 intake manifold, and finally the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are connected coaxially and rigidly.

With such a monolithic turbocharging device in place, your engine is "overclocked" like a computer CPU.

Common turbocharging can be divided into four types: mechanical turbocharging system, air wave boosting system, exhaust gas turbocharging system, and compound turbocharging system.

For example, the Passat uses a discarded turbocharger, the Mercedes-Benz uses a mechanical supercharger, and so on...

The simple thing is to suck a part of the exhaust gas into the intake pipe through the turbocharger to increase the air intake volume and power!

Upstairs said the wrong thing. It's not about re-entering the exhaust gas. In fact, the principle of a turbine is very simple.

In the place of engine exhaust emissions. Connect a turbocharging system. This system is connected to the intake manifold.

But pay attention. The two places connected separately are independent. There is only one impeller that connects them coaxially.

It's like h-h. In this way, both impellers can rotate at the same time. Right?

That's how it works. How much exhaust gas is emitted. Fresh air enters as much as it gets.

Because of the high speed of the car, the entry of fresh air is very difficult. With enough air. The engine burns better.

Burn more thoroughly. The performance of the engine is strengthened by about 20 percent.

At high speeds, turbocharging is more advantageous.

The biggest advantage of turbocharged engine is strong power, explosive power, but also economical and fuel-efficient, at high speed, can easily reach the speed range that the owner wants, such a vehicle is more suitable for unscrupulous galloping, like a wild horse, in the grassland can better reflect its running advantages.

In urban road conditions, the self-priming engine is smoother.

The self-priming engine, the engine air intake is slightly soft, with the increase of the depth of the accelerator pedal, the engine output torque gradually increases, and the turbocharged engine has a turbo delay phenomenon, therefore, the self-priming engine is more suitable for driving in urban road conditions, especially when the traffic jam, the self-priming engine driving feeling is higher, how much the accelerator pedal is pressed, how much power the vehicle has, and the vehicle will not appear to have a sudden increase in power.

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

2. Similar to the function of the supercharger (supercharger), both can increase the air flow into the internal combustion engine or boiler, thereby improving the efficiency of the machine.

3. Commonly used in automobile engines, the turbocharger can increase the horsepower output of the internal combustion engine by using the heat and flow rate of exhaust gases.

4. Generally, the weight of the internal combustion engine will increase after the supercharger is installed, and the energy used to overcome the inertia will rise. Because turbochargers are driven by exhaust engine fumes most of the time, they are superior to superchargers driven by engine crankshafts.

5. However, due to the low exhaust gas flow rate of the engine when the engine is running at low rev, the performance of the turbocharger is not ideal, and the turbo-lag phenomenon occurs.

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.

Hehe, you can see it literally.

First of all, you understand from two aspects, the first is the turbine, the turbine is the rotation from large to small into a performance part. Its main function is to compress the gas from the large to small of the turbine (from the large mouth and out from the small mouth) to make the gas burst out more forcefully under the same pressure.

And supercharging is achieved through the turbine.
