What does turbocharging mean? What are its benefits?

A turbocharger consists of a turbine chamber and a supercharger, which is mainly achieved by a turbo and supercharging. The air intake of the turbine chamber is connected to the engine exhaust manifold, which is connected to the exhaust pipe. The air intake of the supercharger is connected to the air filter tube, the exhaust port is connected to the intake pipe, and finally the turbine and impeller are installed in the turbine chamber and supercharger respectively, which are coaxial and rigidly connected.

The constant pressure turbocharging system collects the exhaust gases from all cylinders of the internal combustion engine into an exhaust pipe with sufficient volume, which is then introduced into the turbine.

One of the benefits is increased engine power and torque. The biggest benefit 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, its maximum power output can be increased by about 40% compared to an engine without a supercharger.

This means that engines of the same size and weight can be supercharged to produce more power, or smaller displacement engines can be supercharged to produce the same amount of power as larger displacement engines.

The second benefit is to save costs and protect the environment. The small size and relatively simple structure of turbocharged engines greatly reduce their R&D and production costs, which are much lower than the cost of optimizing large-displacement naturally aspirated engines. Turbocharged engines use turbocharging technology to reduce CO (carbon monoxide), CH (hydrocarbons) and PM (particulate matter) in emissions, which is beneficial to the environment.

At the same time, the turbocharged engine is also quieter than the naturally aspirated engine.

It is important to know that the main role 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. With a turbocharger installed, the maximum power of the engine can be increased by 40% or more than without a turbocharger. This means that the same engine can put out more power when supercharged.

Take, for example, our most common turbocharged engine. After supercharging, the power can reach the level of the engine, but the fuel consumption is not much higher than that of the engine.

Turbocharging is a technology to increase the amount of air intake, which is to use the exhaust gas from the engine to drive the turbine to achieve the supercharging of the engine, turbocharging can improve the engine power, so that the engine becomes full of power.

It refers to the installation of a turbocharger between the intake pipe and the exhaust pipe, and the turbo is driven by the force of the exhaust to boost the intake air volume. The benefit is that it can increase the density of air entering the intake duct and increase the engine power.

A turbocharger is an air compressor that is powered by exhaust gases generated by the operation of an internal combustion engine. Similar to superchargers, both increase the flow of air into an internal combustion engine or boiler, thereby increasing machine efficiency. Commonly used in automobile engines, turbochargers can increase the horsepower output of internal combustion engines by harnessing the heat and flow of exhaust gases.

In general, the weight of the internal combustion engine of the vehicle will increase after the supercharger is installed, and the energy used to overcome the inertia will increase.

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.

The biggest significance of the existence of turbocharging on the car is to increase the air intake of the car, increase the power of the car under the same displacement, and increase the efficiency of the car's combustion, which is a good thing. But the role of this thing is not only good but also some disadvantages, whether you want to buy this kind of turbocharged car, you should think about it first. <>

The advantage is that once the car turbocharger is turned on, it can increase the air intake of the car, because the efficiency of gasoline combustion is relatively low, you should have learned the internal combustion engine of gasoline in junior high school physics, and its combustion efficiency is generally 30% 40%. That is to say, the liter of oil is really used for power, and the rest is wasted, or the remaining 60% or 70% of the heat is wasted, because oxygen is limitedAt the same time, the efficiency of combustion is limited, and this turbocharging is to increase the speed of oxygen absorption, increase the speed of air intake, and the efficiency of combustion will increase. <>

The increase in combustion efficiency will lead to more sufficient power of the car, because the turbocharged car is the same displacement, for example, yes, the turbocharger itself has no limb problem, and it is no problem to increase the power by 30% or 40%, that is, the displacement of the car, it can achieve even the power state of the car. But do you think there are only good places? The most obvious is the frustration and damage to the engine when the car starts.

The turbocharged car itself is not particularly fast when it is just started, it has a turbocharger starting this process, this starting process has a time delay, the average is 2 3 seconds, I will say that you step on the accelerator for almost 2 3 seconds, this turbocharger starts to work, you can feel that the feeling of this power has a certain delay. And then it's because no matter how much oxygen Sun Jiajun loses, the temperature of the car's engine will be higher when it is runningThere is a problem of how to cool down the temperature is relatively high, and there is no particularly good solution for this at present, which will affect the life of the engine of the truck.

The turbo on the car is particularly useful, which can help the car accelerate instantaneously, especially when climbing the slope. I learned about a good car, and its turbocharger is very powerful.

The specific role of turbocharging: the use of exhaust energy to compress the intake air, and the high-density mixture into the combustion chamber to increase the output power, when the turbine uses the exhaust energy to rotate, the supercharger impeller installed at the other end of the shaft will be compressed intake air into the engine, there is also a mechanical turbocharger, which through the crankshaft, directly by the transmission belt to drive the compressor, increase the intake volume.

Turbocharging is well used in engines, and turbocharging can increase power and improve the performance of diesel engines.

When an engine is equipped with a turbocharger, the maximum power output can be increased by about 40% or more compared to the non-turbocharger. Turbo increases the daily use and maintenance of the engine is a bit more troublesome. Compared with naturally aspirated engines, turbocharged engines have stricter requirements for the working environment and maintenance.

With the exhaust gas turbocharger, the plateau diesel generator set is just as powerful.

Turbochargers are mainly composed of compressors and turbines. The exhaust gas discharged from the diesel engine enters the nozzle through the turbine shell and flows to the turbine blade in a certain direction, pushing it to rotate at high speed, driving the compressor impeller on the coaxial to rotate at the same high speed to produce siphon effect, the siphon principle is: the essence of siphon is generated because of gravity and intermolecular cohesion.

Fresh air is sucked into the compressor casing through the air filter, the speed and density of the air flow increase and the pressure increases through the diffuser, and the air flow energy through the compressor casing and the diffuser becomes static energy, and the pressure is further increased and enters the engine intake pipe, so as to achieve the purpose of air intake pressurization and increase engine power.

Due to the better combustion performance of the engine with turbocharger, fuel savings of 3%-5% can be achieved. Of course, there are advantages and disadvantages, the disadvantage of turbochargers is hysteresis, that is, due to the inertia of the impeller, the engine delay increases or decreases the output power.

The exhaust gas turbocharging system increases the air intake by compressing the air. 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 coaxial impeller, and the impeller pressurizes the air sent by the air filter pipe to pressurize it into the cylinder.

If the supercharger can not be assembled on the matching engine, the role is also greatly reduced, the power of a turbine is directly related to the exhaust temperature and pressure of the engine, whether it is well matched but also to consider whether the choice of turbine flow is appropriate. It is also necessary to observe various data such as air consumption characteristics to maximize the advantages. The main performance indicator of an exhaust turbocharger is the air pressure rise ratio, known as the pressure ratio.

It is expressed as the ratio of compressor outlet air pressure pk to compressor inlet air pressure p1, i.e., nk = pk p1.

Generator manufacturer Dingbo power technicians told us that the performance of the diesel engine supercharger is broken, the engine power will be greatly reduced, there is no supercharging effect, and the exhaust heat dissipation of the motor will not be smooth for a long time. After the supercharger is damaged, the air will not be able to enter the combustion chamber sufficiently, and the power will drop by 30%, and the throttle power will not increase but only emit black smoke.
