Using a turbocharger is one of the most effective ways to improve efficiency and increase engine power. How does a turbocharger work and is it worth having it in your car? From our article you will learn more about how these devices work and their exact uses.
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 easily increased, but in the case of air it is a bit more complicated. One of the most effective solutions that will allow more air to be sucked into the engine is to supply it with compressed air, which, with the same volume, is able to provide much more oxygen necessary during the combustion process.
This is what a turbocharger in a car is for. It is a rotating machine used in motor vehicles, whose main task is to charge and increase the engine's power by increasing the amount of air supplied to it . The turbocharger enables more efficient fuel combustion, thereby improving engine performance without the need to increase its capacity.
How a turbocharger works: mechanism and structure
The mechanism of operation of a turbocharger is based on the use of engine exhaust energy to drive the compressor rotor. This rotor 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 thermal one is the mentioned turbine, which is located in the exhaust manifold. The cold one, i.e. the compressor, is located in the intake pipe. The hot side drives the cold side, which is responsible for creating intake pressure.
Additionally, the turbocharger has two rotors corresponding to these parts - the turbine rotor and the 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 consequence, the engine power increases significantly.
Additionally, the turbocharger consists of the following elements:
- turbine housing and compressor housing,
- center hull,
- sealing rings,
- sliding 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 are some of the benefits that a turbocharger provides:
- increasing engine power,
- better performance,
- greater fuel efficiency,
- reduced exhaust emissions,
- better engine flexibility.
The most frequently mentioned disadvantages related to the use of turbochargers in cars include:
- faster wear of some engine components,
- increased thermal load on the turbine,
- higher engine failure rate,
- the so-called phenomenon turbo lag.
What is turbo lag?
The phenomenon of turbo lag is characteristic of vehicles equipped with a turbocharger. It involves a sudden drop in engine torque within a specific rev range. It is the effect of a delay in the operation of the turbocharger and negatively affects driving dynamics and combustion efficiency, increasing fuel consumption and exhaust emissions.
The main cause of turbo lag is the lack of a direct connection between the rotor and the combustion engine . In passenger cars, turbo lag is felt mainly at low revs, when the rotor is not turning 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. Most often, this type of supercharging is used in modern diesels 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 gasoline engine, it is often necessary to replace components such as the cooling system, exhaust system, fuel system or electronics. Most often, you also need 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 several thousand zlotys. In the case of replacement or used turbines, the price will be slightly lower.
However, you must remember that purchasing just a turbocharger is not everything. This should include its installation and possible adaptation of other car elements to work with the new device. How much can it cost? It all depends on what car and engine the turbocharger is to be installed in. In the case of gasoline engines, the cost of turbulence may increase significantly due to the need to adapt more elements.
The turbocharger installation service along 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 will be a good idea to replace the engine oil and filters, as well as check the condition of the oil pump. However, in the long run, 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's power by up to 40% while maintaining its relatively low weight. Although purchasing and installing this device is more expensive, its use has many advantages. The turbocharger allows you to improve performance, increase fuel efficiency, and reduce the emission of harmful substances into the environment.
