What are the technical advantages and disadvantages of the turbocharged engine of the current car

I have an article in my space that professionally introduces the working principle of turbochargers, you can take a look. The biggest advantage of turbocharging is that under the current technical conditions, the only mechanical device that can increase the output power of the engine under the same working efficiency can theoretically increase the power by 40%-50%.

The only drawbacks: Turbo lag, maintenance is also more expensive, and the engine life is shorter than that of the NA engine.

Turbochargers are divided into exhaust gas turbocharging and mechanical turbocharging. Exhaust gas turbocharging uses exhaust gases to drive the impeller to rotate. Exhaust gas pressurization consists of an impeller for exhaust and intake, connected by a rotor shaft.

When the engine starts, the oil pump runs to press the oil into the main oil channel, which enters the intermediate shaft of the two impellers, and uses the oil pressure to suspend the intermediate shaft to make it run at high speed. The supercharger presses air into the engine cylinder and takes in more air than the normal one. Turbocharged engines with exhaust gases will make use of exhaust gases, mechanical ones will not.

With a supercharged gas engine, it is powerful, fuel consumption increases, choose carefully.

Oil. Air filtration requirements are high. The service life is not perfect.

High maintenance costs. Mostly there are turbine hold-ups. But it's not very obvious that it's better now.

Turbine intervention is still relatively early. Most of the advantages are known. Low fuel consumption.

The power is noticeably better after the turbine intervenes.

It has two structures, one is to drive the supercharger through the exhaust gas of the engine, which is commonly used. There is also an electric one. The main thing is that the speed of the power burst is different. Pressurization requires high rpm. The disadvantage is that the maintenance cost is high.

A car engine can be said to be the heart of a car. The quality of a car's engine determines the power of the car. Turbocharged engines, I don't know if my friends have heard of them.

Today, Bian Xiao from the automobile maintenance technology network came to talk about turbine engines for friends. What are the advantages and disadvantages of turbine engines? Do any friends know?

Let's take a look at it with a car repairer.

Introduction to Turbocharged Engines: Introduction.

A turbocharged engine is an engine that is equipped with a turbocharger. A turbocharger is actually an air compressor that compresses air to increase air intake. It uses the inertial impulse of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine center kicks the coaxial impeller, and the impeller pressurizes the air sent from the air filter line into the cylinder.

When the engine speed increases, the exhaust gas exhaust speed increases in sync with the turbine speed, and the impeller compresses more air into the cylinder. The pressure and density of the air increases, burning more fuel. The power output of the engine can be increased by increasing the amount of fuel and adjusting the engine speed accordingly.

Introduction to turbocharger functions: Functions.

The main role of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine, making the car more dynamic. With a turbocharger attached to the engine, the maximum power can be increased by 40% or even more than without a turbocharger. This means that the same rent-issuing motor can output more power when pressurized.

Take, for example, the turbocharged engines that we often see. After supercharging, the power can reach the level of the engine, but the fuel consumption is not much higher than that of the engine. On the other hand, it is to improve fuel economy and reduce exhaust emissions.

The above is the content of the car turbocharging function introduced by Bian Xiao Automobile Maintenance Technology Network for friends. From the content introduced to friends by Bian Xiao Auto Maintenance Technology Network, friends can also see that this technology is still very powerful. I hope that the introduction of Bian Xiao Auto Maintenance Technology Network can be helpful to friends.

Advantages: Under the premise of the same displacement, the power of the turbocharged engine is higher than that of the engine of the same displacement, which means that the power of the draft is stronger. Relative fuel consumption is less.

Disadvantages: The engine is relatively expensive to maintain, and it takes dozens of seconds to idle after starting and before stalling to ensure that the turbocharger is well cooled and lubricated.

1. With the progress of science and technology, people continue to develop various types of engines for different purposes, but no matter what kind of engine, its basic premise is to produce power from a certain fuel combustion. Therefore, the electric motor with electricity as the energy is not in the category of the engine.

2. The body is the skeleton of the engine, the installation foundation of the engine's various mechanisms and systems, and all the main parts and accessories of the engine are installed inside and outside to bear various loads. Therefore, the body must have sufficient strength and rigidity. The body group is mainly composed of parts such as cylinder block, crankcase, cylinder head and cylinder gasket.

3. The cylinder block and the upper crankcase of the water-cooled engine are often cast into one, which is called the cylinder block - the crankcase, which can also be called the cylinder block. The cylinder block is generally made of gray cast iron, the cylindrical cavity of the upper part of the cylinder block is called the cylinder, the lower half is the crankcase supporting the crankshaft, and the inner cavity is the space for the crankshaft to move. There are many stiffeners, cooling water jackets and lubricating oil channels cast inside the cylinder block.

The advantages and disadvantages of the turbocharged engine are as follows: Advantages: The exhaust energy of the engine is effectively used to provide supercharging for the air intake system, and the energy-saving effect is good.

Disadvantages: The exhaust energy in the low-speed zone is insufficient, and the pressurization effect is not obvious. The involvement of turbocharging is not felt until a certain speed, and there is a sense of sluggishness and incoherence in acceleration.

Here's the extended information: The main function of turbocharging: to increase the air intake of the engine, thereby increasing the power and torque of the engine, making the car more dynamic.

Another aspect is to improve fuel economy and reduce tailpipe emissions. Working under suitable working conditions and after the turbine positive pressure, it can reduce emissions and exhaust noise, and can greatly increase the power in the case of a small volume increase. The disadvantage is that the acceleration response is slow, and the linearity and smoothness are not enough. Huai Hall.

The advantages and disadvantages of turbocharged engines are as follows: 1. Advantages: Effective use of the exhaust energy of the engine provides supercharging and energy-saving effect for the intake system.

2. Disadvantages: The exhaust energy in the low-speed area is insufficient, and the supercharging effect is not obvious, and the intervention of the turbocharging can be felt after a certain speed, and the acceleration is delayed and incoherent. Here's the extended material:

The main functions of turbocharging: 1. Increase the air intake of the engine, thereby increasing the power and torque of the engine, so that the car is more energetic. On the other hand, it is about improving fuel economy and reducing tailpipe emissions.

2. Working under the working conditions after the turbine is properly matched and the positive pressure of the turbine can reduce emissions and exhaust noise, and the power can be greatly increased under the condition that the volume increase is not large. The disadvantage is that the acceleration response is slow, and the work is not linear and smooth.

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 produce more power after being pressurized.

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, on another level is to improve fuel economy and reduce exhaust emissions.

Advantages: Under the premise of the same displacement, the power and torque of the engine can be greatly improved, about 40%, that is, it can be equivalent to. Fuel burns more fully.

Disadvantages: Maintenance is quite expensive, and most of the time in the city the turbocharger does not work, because it is generally set at about 3500 rpm before the turbocharger is activated. Moreover, the power output response of the car with turbocharging lags behind, and there will be a delay in speeding up when the accelerator is pressed, because the exhaust gas turbocharger needs the exhaust gas drive of the engine, and the turbocharger does not immediately improve the work efficiency when you step on the accelerator, and it will take more than two seconds to react.
