Using a turbocharger is one of the most effective ways to improve engine efficiency and increase power. How does a turbocharger work and is it worth having one in your car? In our article you will learn more about how these devices work and their exact applications.
What is a turbocharger and what is it used for?
The power of an internal combustion engine is directly related to how much fuel and air we supply to it. The amount of fuel can be increased easily, but with air it is a bit more complicated. One of the most effective solutions to drawing more air into the engine is to supply it with compressed air, which, with the same volume, is able to provide a lot of oxygen necessary during the combustion process.
This is exactly what a turbocharger in a car is for. It is a rotating machine used in motor vehicles, the main task is to boost and increase the engine power by increasing the amount of air supplied to it . A turbocharger enables more efficient fuel combustion, thereby improving engine performance without the need to increase its capacity.
How a Turbocharger Works: Mechanism and Construction
The operation of a turbocharger is based on the use of engine exhaust energy to drive the compressor rotor. This impeller draws in air and then compresses it before feeding it to the engine. As a result of this process, more oxygen enters the cylinders, which allows for better fuel combustion and increased vehicle power.
The turbocharger is divided into two sides - hot and cold. The heat source is the aforementioned turbine, which is located in the exhaust manifold. The cold one, i.e. the compressor, is located in the intake tract. The hot side drives the cold side, which is responsible for generating intake pressure.
Additionally, the turbocharger has two rotors corresponding to these parts - turbine rotor and compressor rotor. They are connected by a common shaft, which means they rotate simultaneously. The turbine is powered by exhaust gases coming out of the engine, and the air compressed by the compressor is sucked in. . As a result, the engine power increases significantly.
Additionally, the turbocharger consists of the following elements:
- turbine housing and compressor housing,
- middle hull,
- sealing rings,
- slide and thrust bearings,
- oil channels,
- wastgate or blow-off valves.
Advantages and disadvantages of a turbocharger
Having a turbocharger in your car obviously has its advantages and disadvantages. Here Some of the benefits a turbocharger provides include:
- increasing engine power,
- better performance,
- greater fuel efficiency,
- reduced exhaust emissions,
- better engine flexibility.
Down the most frequently mentioned disadvantages related to the use of turbochargers in cars, the following can be included:
- faster wear of some engine components,
- increased thermal load of the turbine,
- higher engine failure rate,
- the phenomenon of the so-called turbo lag.
What is turbo lag?
The turbo lag phenomenon is typical for vehicles equipped with a turbocharger. It involves a sudden drop in engine torque within a specific RPM range. It is the result of a delay in the operation of the turbocharger and has a negative impact on driving dynamics and fuel economy, increasing fuel consumption and exhaust emissions.
The main cause of turbo lag is the lack of direct connection between the rotor and the combustion engine. . In passenger cars, turbo lag is felt primarily at low revs when the rotor does not rotate at a sufficient speed and the boost pressure in the system is too low to achieve turbo acceleration.
Can every car have a turbocharger?
Theoretically, a turbocharger can be installed in a car with any engine. In practice, however, in some cases it will be necessary to make some corrections and modifications. This type of supercharging is most often used in modern diesel engines or spark-ignition cars, which are adapted to withstand a large increase in the power of the drive unit.
To install a turbocharger in a car with a petrol engine, it is often necessary to replace components such as the cooling system, exhaust system, fuel system or electronics. Most often, it is also necessary to use an intercooler, the so-called. intercooler .
What are the costs of installing a turbocharger and is it worth it?
A turbocharger is not the cheapest car part. The cost of purchasing a new, original device ranges from several to even several thousand zlotys. In the case of replacement or used turbines the price will be slightly lower.
However, it must be remembered that purchasing just a turbocharger is not everything. This must include its installation and any necessary adaptation of other car components to operate with the new device. How much might it cost? It all depends on which car and which engine the turbocharger is to be installed in. In the case of petrol engines, the cost of turbocharging can increase significantly due to the need to adapt more components.
The service of installing a turbocharger, together with the necessary modification of the exhaust system, costs from several hundred to over a thousand zlotys, but during such a procedure it is also worth taking care of other elements that affect the operation and durability of the turbine. It would be a good idea to change the engine oil and filters, as well as check the condition of the oil pump. In the long run, however, a turbocharger can reduce fuel costs. .
Why is it worth installing a turbocharger in your car?
Thanks to a turbocharger in a car, it is possible to increase the engine power by up to 40% while maintaining its relatively low weight. Although the purchase and installation of this device involves a higher expense, its use has many advantages. A turbocharger allows you to improve performance, increase fuel efficiency, and reduce harmful emissions into the environment.
