Turbocharger: What Is It And How Many Types Does It Have?

The air entering a turbocharged diesel engine compresses before the fuel injection, which is a considerable change from a standard gasoline engine. It is where AVO turbochargers play a crucial role in the diesel engine’s power production and efficiency. A turbocharger is a technology that uses forced induction to assist an engine in creating more power and torque. A turbo sucks in the air, cools it, and forces more air into the engine than it would obtain from its conventional intake.
What Is a Turbocharger?
The turbocharger is in between the engine and the exhaust, which is a miniature turbine. The turbocharger, connected to both the engine and the air intake, uses the exhaust gases to spin the turbine, which forces more air into the engine and enhances the car’s power. A turbocharger comprises four elements that work together to make it work. These include:
The turbocharger has an air intake, an exhaust intake, two impellers (a turbine in the back and a compressor in the front), and a charged air exhaust that flows to the intercooler, and it looks like a snail. There’s also an oil hose line.
A secondary radiator, or intercooler, intercepts the charged air blasted out of the turbocharger before reaching the engine, lowering its temperature. As a chilling agent, it makes use of coolant.
A wastegate is a valve between the exhaust and the turbocharger that boosts pressure by bypassing the turbine.
● ECU Tuning
Compared to a car with an aspirated engine, the electronic brain of a turbocharged engine requires different tuning for fuel-to-air mixes and ignition timing. As a result, adding a turbocharger to an engine necessitates reprogramming the engine’s electronic control unit (ECU) to make it work properly.
Types Of Turbochargers
There are several different types of turbochargers, as listed below:
1. Single Turbocharger
The most typical turbocharged system is a single turbocharger. It has a single turbine, and you can typically find it in cars that don’t require many horsepowers.
Adding a second turbocharger increases the amount of air pumped into the engine, resulting in increased power and torque. The arrangement is similar to that of a single turbo system.
3. Compound Charged
When a turbocharger and a supercharger are combined, the result is a compound-charged system. The turbocharger extends the amount of top-end horsepower while the supercharger generates more rapid torque.
An e-turbocharger, based on the design of Formula 1 cars, adds electricity to the mix to alleviate turbo lag. Between the turbine casing and the compressor is a small electric motor that runs on a 48V electrical system. Because the electric motor can spin the compressor faster than the exhaust gases, the time between no boost and boost reduces.
5. Hot-V Turbocharger
Mechanics install the turbocharger or turbochargers inside the “V” of an engine in a “Hot-V” arrangement. It minimizes the space necessary for an engine and the distance travelled by charged air between the compressor and the motor. As a result, the turbocharger or turbochargers can spool up faster, reducing lag.
The turbine and compressor are also separated and placed on opposing sides of the engine in a “Hot-V” configuration. It lowers heat build-up in the then-charged air, lowering the cooling load on the intercoolers.
An AVO turbocharger improves an engine’s performance by increasing airflow. It results in higher power and torque. Simultaneously, turbochargers can generate a lot of energy, manufacturers can reduce engine displacement, resulting in improved efficiency and emissions.
